About Dementia

Prescribing Dementia

If you’re becoming increasingly forgetful, particularly if you’re over the age of 65, it may be a good idea to talk to your GP about the early signs of dementia.

As you get older, you may find that memory loss becomes a problem. It’s normal for your memory to be affected by age, stress, tiredness, or certain illnesses and medications. This can be annoying if it happens occasionally, but if it’s affecting your daily life or is worrying you or someone you know, you should seek help from your GP.

How common is dementia?

According to the Alzheimer’s Society, there are around 800,000 people in the UK with dementia. One in three people over 65 will develop dementia, and two-thirds of people with dementia are women.

The number of people with dementia is increasing because people are living longer. It is estimated that by 2021, the number of people with dementia in the UK will have increased to around 1 million.

What is dementia?

 

Dementia is a common condition. Your risk of developing dementia increases as you get older and the condition usually occurs in people over the age of 65.

Dementia is a syndrome (a group of related symptoms) associated with an ongoing decline of the brain and its abilities. This includes problems with:

memory loss

thinking speed

mental agility

language

understanding

judgment

People with dementia can become apathetic or uninterested in their usual activities, and have problems controlling their emotions. They may also find social situations challenging, lose interest in socializing, and aspects of their personality may change.

A person with dementia may lose empathy (understanding and compassion), they may see or hear things that other people do not (hallucinations), or they may make false claims or statements.

As dementia affects a person’s mental abilities, they may find planning and organising difficult. Maintaining their independence may also become a problem. A person with dementia will therefore usually need help from friends or relatives, including help with decision making.

Your GP will discuss the possible causes of memory loss with you, including dementia. Other symptoms can include:

increasing difficulties with tasks and activities that require concentration and planning

depression

changes in personality and mood

periods of mental confusion

difficulty finding the right words

Most types of dementia can’t be cured, but if it is detected early there are ways you can slow it down and maintain mental function.

Diagnosis Difference

Carol and her mum

Diagnosis

By Carol

 

Once a diagnosis has been given to dementia, things

fall into place of why the behaviour’s has been 

happening, Its a bit of a relief to get a name for 

odd happening’s but a protective feeling comes

into play and suddenly I started to help more and

I become very protective over my Mum just like 

you do your child, Suddenly I became the protector,

the one that chose what would be okay to do, or 

not to, The one that had to make sure Mums life

was happy and safe, comforting her daily and 

telling her everything was going to be alright, I 

told her the day of the diagnosis we were in this

together and we would see it through as best we 

could. I may not have always got things right but

I will always believe I dealt with it the best way I 

could. Mum looked at me as the Mum and if I told

her not to do something then I knew she wouldn’t

do it, This is where you need to educate yourself about

and what to expect, how to deal with certain 

situations with the best outcome,what not to say and

to know the person is not giving you a hard time but 

the dementia is giving the person a hard time, It’s a scary

world full of uncertainties of the outcome but if you 

can say you have given it your full understanding, time, love

and patience then you have done your best and that

is all you can do. Your heart will break into tiny pieces 

watching a loved one getting confused and scared of 

changes what they feel not to be right but you need to be

stronger than never before and see the person through 

dementia, not taking independence away but stepping in

to help when you see the person struggling and getting

embarrassed, angry and frustrated. Imagine yourself in 

the situation sometimes too confused to do the simplest 

of tasks, to say a word but the wrong word comes out, they 

are aware of the changes and it must be so terrifying to 

know your mind is not your own, patience and comfort is 

needed at all times, keep reminding yourself the person 

is very ill even if they look the same. We need to get into 

the person’s reality as sometimes it is impossible for 

the person to get into our reality, always remember we 

can come out anytime we want to and the person cant,

they are stuck in the confusion and it’s very cruel to watch.

Dementia is evil in what it does and takes away for all 

concerned, life will never be the same again after you 

have looked dementia in the face daily but once you 

look back and see how well you did cope with the changes

you will feel proud to have helped the person along the 

way, no one is perfect and you will make mistakes but if

we learn from these then it won’t happen again and we can 

find different coping strategies to help us along.

Remember to get as much help as you can, take Me Time 

and do the things you enjoy when you have time off,

too many people get lost and its hard to get back the 

life you once had, slot it in in your Me Time and become

the person you once was and do the things you enjoy,

this  way it will recharge your batteries to deal with the 

battle you are fighting with dementia.

 

 

 

Kind regards

What’s the difference between Alzheimer’s and Dementia

What’s the Difference

Is one of the more commonly asked questions about Alzheimer’s disease and

Dementia.

Let’s talk about the differences.

Alzheimer’s is a disease, dementia is not actually a disease but a collection of symptoms that occur when the brain cells stop working properly. You might also hear it described as a condition.

Dementia is a broad term used to describe a set of symptoms including Alzheimer’s Vascular Dementia, Dementia with Lewy bodies, Frontotemporal dementia, and many other types, in all there are over one hundred types of Dementia. Alzheimer’s disease and dementia are often used

interchangeably as many people believe that one means the other. In fact, the distinction between the two diseases often causes confusion for the patients, families and caregivers, see how the two, while related, are remarkably different.

What is Dementia?

Dementia is a term used for different symptoms including impaired thinking and memory, it is a term that is often associated with the cognitive decline of aging. However, issues other than Alzheimer’s can cause dementia. Other common causes of dementia are Huntington’s disease, Parkinson’s disease, and Creutzfeldt-Jakob disease.

What is Alzheimer’s disease?
Alzheimer’s disease is the most common cause of dementia-causing as many as 50 to 70% of all dementia cases. In fact, Alzheimer’s is a very specific form of dementia. Symptoms of Alzheimer’s include impaired thought, impaired speech, and confusion.
Doctors use a variety of screenings to determine the cause of dementia including blood tests, mental status evaluations, and brain scans.

How Are They Different?

When a person is diagnosed with dementia, they are being diagnosed with a set of symptoms.

Don’t forget, that forgetfulness is a normal part of aging and not necessarily a sign that you may have dementia but if you

are at all overly worried about it, It is probably best to go see your doctor.

Another major difference between the two is that Alzheimer’s is not a reversible disease. It is degenerative and incurable at this time

. Some forms of dementia, such as a drug interaction or a vitamin deficiency, are actually reversible or temporary. Once a cause of dementia is found appropriate treatment and counseling can begin. Until a proper diagnosis is made, the best approach to any dementia is engagement, communication, and loving care. 

Thinking About Dementia

Cultural responses to most illnesses differ; dementia is no exception. These responses, together with a society’s attitudes toward its elderly population, affect the frequency of dementia-related diagnoses and the nature of treatment. Bringing together essays by nineteen respected scholars, this unique volume approaches the subject from a variety of angles, exploring the historical, psychological, and philosophical implications of dementia. Based on solid ethnographic fieldwork, the essays employ a cross-cultural perspective and focus on questions of age, mind, voice, self, loss, temporality, memory, and affect. Taken together, the essays make four important and interrelated contributions to our understanding of the mental status of the elderly. First, cross-cultural data show the extent to which the aging process, while biologically influenced, is also very much culturally constructed. Second, detailed ethnographic reports raise questions about the behavioral criteria used by health care professionals and laymen for defining the elderly as demented. Third, case studies show how a diagnosis affects a patient’s treatment in both clinical and familial settings. Finally, the collection highlights the gap that separates current biological understandings of aging from its cultural meanings. As Alzheimer’s disease and other forms of dementia continue to command an ever-increasing amount of attention in medicine and psychology, this book will be essential reading for anthropologists, social scientists, and health care professionals.


My war with Dementia

Hi,
My name is Carol Bevin and my passion is dementia after losing my gorgeous
Mum on Boxing Day 2012 after 15 long years of heartache, watching the woman

who always made everything right in my life, slowly fade away with dementia.

 

Me and my gorgeous mum.

Going from a busty outgoing lady to a shell, existing in her
bed, unable to communicate, Dementia is a cruel evil illness that takes
everything away and leaves heartache and destruction to lives. I believe
I will never be the same person I was before Mums diagnosis, It changes
lives and hearts and rips them into a million pieces and leaves you
empty just asking why and how this illness took away what it did.
I lost her in a way that I needed closure and never got it, a so-called
carer broke her shoulder on 8th December 2012 and she was in the hospital

until she took her last breath 26th December 2012. They even dressed

They even dressed her in a jumper to go to the hospital with a suspected

broken shoulder,  her face shown me she was in agony, the hospital cut the
jumper off so they didn’t cause any more pain to her. Knowing she was
not going to recover was horrendous to know, you are waiting for the end
every day you think is the last, all I could do was kiss and cuddle
her telling her I was with her and there I would stay until she
decided she was going to Heaven, a friend brought a camp bed and there
I slept taking turns with my daughter Nicola, Nothing else mattered
only making sure Mum went out of this world as comfortable as
possible and knowing she was loved so much by us all. People told
me it would be a relief but in all honesty, It hit me very hard, I
think when someone has been so poorly for so long,

I believed she would always be there,

The word dead was horrific for me
to say or think about, I had the guilt of

letting her go into the care
home that someone hurt her in, Guilt I

couldn’t find out who did it, the guilt I wasn’t able to care for her at

home where she would have been safe. Grief gives you feelings you have never

experienced before, I was told by a good friend there is no right or wrong way to
grieve and just go with the flow, I did just that but I kept coming
back to why someone would hurt a very poorly human being, I prayed
for a few years for her to have a heart attack and her suffering would
end but to get hurt then die is not the way it should have been and
I think that’s why I couldn’t get over her for so long. Me and Mum
made a promise to each other and that was she would always remember
she loved me and my promise was I would be with her until the end, as
I walked with her coffin on my shoulder and put it down I knew my
promise was kept to her.
Today I am at war with dementia, I tell anyone who will listen
how it will be and I try to give tips on how to make things a bit
easier coping with a loved one with dementia, I have cared for others
living with dementia and I have just finished 7 months of live-in care
with a lady in Scotland who has Alzheimers and lives alone, Now I am
able to talk about different roles of caring from a daughters view
and now also as a professional carer living with a stranger.

History of dementia

Auguste Deter,

The History of Dementia

In 1906 Auguste Deter, a woman in her early 50s became the first person diagnosed with Alzheimer’s disease, a form of dementia. The disease is named after the doctor who first described it, Alois Alzheimer. The disease is characterized by odd behavior, memory problems, paranoia, disorientation, agitation, and delusions. After Deter’s death, Alzheimer performed a brain autopsy and discovered dramatic shrinkage and abnormal deposits in and around nerve cells.

 

Alois Alzheimer.

In 1910 the term “Alzheimer’s Disease” was formally used. In 1974 Congress established the National Institute on Aging (NIA), the primary federal agency supporting Alzheimer’s research.

 

What Is Dementia?

Dementia is not a specific disease, it is a broad term that characterizes many different conditions, such as Alzheimer’s disease, vascular dementia, frontotemporal dementia, and other disorders. Dementia refers to a group of symptoms that can be caused by several different brain disorders.

In general, dementia is characterized by impaired intellectual functioning that interferes with daily activities or personal relationships. This impairment can include memory loss, language difficulty, decreased perception, and impaired reasoning. Sometimes, people with dementia go through personality changes or develop delusions. Dementia is often mistaken as senility or senile dementia which views serious mental decline as a normal part of aging, when in fact, it requires professional treatment.

Types of Dementia

There are several different classifications of dementia. Dementia can be classified by either the area of the brain that is affected, whether it is progressive, or whether it results from another disorder (primary or secondary).

Cortical Dementias

Cortical dementias occur because of problems in the cerebral cortex, the outer layer of the brain. This type of dementia plays an important role in memory and language and people with cortical dementias usually have severe memory loss and can’t remember words or understand language. Creutzfeldt-Jakob and Alzheimer’s disease are two types of cortical dementia.

Subcortical Dementias

Subcortical dementias occur because of problems in the part of the brain beneath the cortex. The ability to start activities and speed of thinking is usually affected by subcortical dementias. Forgetfulness and language problems are typically not developed in subcortical dementias. Parkinson’s disease, Huntington’s disease, and HIV can cause these types of dementia.

Progressive Dementia

Progressive dementias become worse over time and patients eventually lose more of their abilities. Alzheimer’s disease, Lewy body dementia, vascular dementia, and frontotemporal dementia are types of progressive dementia.

Primary Dementia

Primary dementia patients only show symptoms of dementia. Alzheimer’s disease is a form of primary dementia, which accounts for 50%-70% of all dementia cases.

Secondary Dementia

A secondary dementia is a form of dementia that develops as a peripheral condition to a pre-existing mental illness or condition. Brain infections, progressive supranuclear palsy, and multiple sclerosis are examples of conditions that can cause secondary dementias to form. Many types of secondary dementias can be stopped or reversed, unlike other types of dementia.

Dementia Stages

Doctors will determine a patient’s stage by asking a variety of questions to the patient and the caregiver. The Mini-Mental Stage Examination is a screening tool used to identify cognitive decline on a scale of 0 to 30. Stage diagnosis can help the doctor create a treatment plan.

No Impairment

There are no obvious signs at this stage and people are able to function independently.

Very Mild Impairment

Symptoms at this stage are slight and seem to appear as forgetfulness associated with aging.

Mild Impairment

Patients are still able to do daily routine and tasks. Symptoms include the following:

  • Forgetfulness
  • Memory loss
  • Losing items
  • Trouble managing finances
  • Confusion while driving
  • Trouble managing medications
  • Loss of concentration

 

Moderate Impairment

Patients typically have trouble performing daily routine and tasks. Symptoms include the following:

  • Trouble holding urine
  • Increased memory loss and forgetfulness
  • Inability to use or find the correct words
  • Difficulty doing challenging mental math
  • Increased social withdrawal

 

Moderately Severe Impairment

Patients will need assistance with daily routine and tasks. Symptoms include the following:

  • Increased memory loss
  • Confusion about location or previous events
  • Trouble with less challenging mental math
  • Needing help with selecting appropriate wardrobe

 

Severe Impairment

Patients will need more assistance in daily routine and tasks. Symptoms include the following:

  • Needing assistance when getting dressed
  • Needing assistance when using the restroom
  • Wondering and getting lost
  • Unable to recall names of loved-ones or caregivers
  • Sleep disturbances
  • Changes in personality (paranoia or hallucinations)

 

Very Severe Impairment

Patients will need constant care. Symptoms include the following:

  • Loss of language skills
  • Loss of awareness of surroundings
  • Assistance when eating
  • Unable to control urination
  • Loss of muscle control to smile, swallow, walk, or sit without support

Alzheimer’s Disease Causes

The most common cause of dementia is Alzheimer’s disease. More than 5 million people are living with Alzheimer’s disease, and ½ million die each year from it. It is the 6th leading cause of death in the U.S., and the 5th leading cause of death for seniors 65 and older. Two-thirds of seniors with Alzheimer’s are women. Up to 5% of those living with Alzheimer’s have the early-onset form of the disease and are diagnosed in their 40s or 50s.

On the microscopic level, Alzheimer’s disease shows up in the brain with two characteristic abnormalities: amyloid plaques and neurofibrillary tangles. Amyloid plaques are abnormal clumps of protein (beta-amyloid) found between the nerve cells of the brain that impair communication between nerve cells. Neurofibrillary tangles are damaged proteins (tau proteins) that collect into “tangles,” which cause improper functioning of nerve cells, leading them to disintegrate. It is unknown if amyloid plaques and neurofibrillary tangles cause Alzheimer’s or if they result from the disease itself.

Alzheimer’s Disease Symptoms and Treatment

Patients with Alzheimer’s disease suffer progressive disability over the course of the illness. Generally, patients with Alzheimer’s can live from 2 to 20 years from diagnosis; on average patients’ life expectancy is 8-10 years. Alzheimer’s disease usually causes a decline in thinking ability, memory, movement, and language. Bizarre, withdrawn, or paranoid behavior may also occur as the disease progresses.

Early in the disease, patients may only have subtle symptoms such as changes in personality or lapses in memory. As the disease worsens, patients may experience bouts of disorientation and may notice difficulty in performing daily tasks. In later stages of the disease, patients can no longer care for themselves, and they may become paranoid or hostile. In the later stages of the disease patients lose the ability to swallow and control bladder and bowel functions. They may no longer recognize family members and may not be able to speak. Fatal complications of Alzheimer’s include loss of ability to swallow that can lead to aspiration pneumonia, and incontinence leading to urinary tract infections or sepsis (severe infection).

Vascular Dementia

After Alzheimer’s disease, the second most common cause of dementia is vascular dementia. It is estimated that vascular dementia makes up 15%-20% of dementia cases.

 

Vascular Dementia Causes

Unlike Alzheimer’s disease, vascular dementia occurs when part of the brain doesn’t get enough blood carrying the oxygen and nutrients it needs. Vascular dementia may be caused by brain damage from strokes, atherosclerosis, endocarditis, or amyloidosis. Structural damage to the brain tissue, either by blocked arteries, blood clots, or bleeding (hemorrhage) causes symptoms of vascular dementia.

 

Vascular Dementia Symptoms

Vascular dementia may coexist with Alzheimer’s disease and many of the symptoms overlap. However, people with vascular dementia only usually maintain their personality. Common vascular dementia symptoms include the following:

  • Problems with short-term memory
  • Wandering or getting lost
  • Laughing or crying at inappropriate times
  • Trouble concentrating
  • Trouble managing money
  • Inability to follow instructions
  • Loss of bladder or bowel control
  • Hallucinations

Other symptoms of vascular dementia include nighttime wandering, depression, incontinence, or one-sided body weakness associated with larger strokes.

 

Vascular Dementia Risk Factors

Vascular dementia almost never occurs without the patient having high blood pressure. Stroke is also a risk factor, 25%-33% of strokes are thought to result in some degree of dementia. Smoking, high cholesterol, diabetes, and heart disease are also vascular dementia risk factors. Men, people between the ages of 60 and 75, and African-Americans have increased risk of vascular dementia.

Vascular Dementia Treatment and Prognosis

There are currently no treatments that can repair the damage of vascular dementia once it has happened. However, behavioral interventions can improve the quality of life for everyone involved. It may be helpful to leave reminder notes, remind the patient what day it is, and keep the patient connected to their loved-ones.

If the condition that initially caused vascular dementia goes untreated, the prognosis is not good. Eventually, untreated vascular dementia usually ends in death from stroke, heart disease, or infection. Catching vascular dementia early and preventing further damage makes for a better prognosis.

Multi-Infarct Dementia

One type of vascular dementia called multi-infarct dementia (MID) is caused by multiple small strokes in different areas of the brain. Other types of vascular dementia include Binswanger’s disease and CADASIL (cerebral autosomal dominant arteriopathy with subcortical infarct and leukoencephalopathy).

 

Multi-Infarct Dementia Causes

When the smaller blood vessels of the brain become blocked tiny areas of the brain, especially in the “white matter” (outer part of the brain), become damaged. These small strokes can be in “silent areas” (areas of the brain that when damaged do not show outward signs of disability) or may occur in important regions of the brain such as the hippocampus or parts of the left hemisphere where damage causes disability to be apparent.

Multi-Infarct Dementia Symptoms

Multi-infarct dementia (MID) symptoms may appear gradually over time, or they may suddenly occur after a stroke. The symptoms of MID are very similar to those of vascular dementia. Common MID symptoms include the following:

  • Problems with short-term memory
  • Wandering or getting lost
  • Laughing or crying at inappropriate times
  • Trouble concentrating
  • Trouble managing money
  • Inability to follow instructions
  • Loss of bladder or bowel control
  • Hallucinations

 

Multi-Infarct Dementia Risk Factors

Typically, multi-infarct dementia occurs in people ages 55 to 75 and it is more common in men than women. MID risk may be increased if any of the following medical conditions are present:

  • Atrial fibrillation
  • Previous strokes
  • Heart failure
  • Cognitive decline prior to stroke
  • High blood pressure
  • Diabetes
  • Atherosclerosis

Smoking, excess alcohol consumption, poor diet, and little to no physical activity are also risk factors for MID.

 

Multi-Infarct Dementia Treatment and Prognosis

Treatment of multi-infarct dementia focuses on controlling the symptoms and reducing the risk of future strokes. Medications may include memantine, nimodipine, hydergine, folic acid, and CDP-choline. Certain serotonin reuptake inhibitors may also help neurons grow and reestablish connections in the brain. Calcium channel blockers may also be beneficial for short-term cognitive function. Regular exercise, cognitive training, and rehabilitation are also treatment options.

There is no cure for MID, but patients can use medication and cognitive training to help preserve mental function. Some patients die soon after a MID diagnosis, whereas others may keep living years after.

Lewy Body Dementia (LBD)

The third most common type of dementia is Lewy body dementia (LBD), also called dementia with Lewy bodies (DLB). The “Lewy body” is an abnormal protein found microscopically in the brain of patients with this type of dementia.

 

Lewy Body Dementia Causes

Lewy bodies are made up of a protein called alpha-synuclein. When these proteins build up, they keep the brain from making the right amount of acetylcholine and dopamine. Acetylcholine is a chemical that affects memory and learning and dopamine is a chemical that affects movement, moods, and sleep. The reason for Lewy body build up is currently unknown and scientists are also unsure of why some people get LBD and others do not.

Lewy Body Dementia Symptoms

Symptoms of Lewy body dementia are similar to Alzheimer’s, including impaired memory, confusion, and poor judgment. LBD may also cause depression, lack of interest, anxiety, and delusions. Patients may have problems with their sleeping pattern (REM sleep behavior disorder, trouble falling asleep, restless leg syndrome). LBD symptoms also include hallucinations and parkinsonian symptoms (shuffling gait, inability to stand straight, and shaking).

Lewy Body Dementia Treatment and Prognosis

There are no medications that can stop or reverse Lewy body dementia, but medications can help relieve symptoms for a few months. Donepezil and rivastigmine are medications that can help with thinking problems. Levodopa can help improve movement problems or rigid limbs. Melatonin or clonazepam can ease patients’ sleep problems. Physical therapy, counseling, psychotherapy, and occupational therapy may also be able to help ease LBD symptoms.

LBD is a progressive disease and the lifespan of patients with LBD varies from 5 to 8 years. Patients with LBD may die from complications

Frontotemporal Dementia (FTD)

Frontotemporal dementia (FTD), also called frontal lobe dementia and previously known as Pick’s disease, is a diverse group of uncommon disorders that affect the frontal and temporal lobes of the brain. The frontal and temporal regions of the brain control behavior, judgment, emotions, speech, and some movement. Damage to these areas accounts for the symptoms that separate frontotemporal dementia from other types of dementia.

Frontotemporal Dementia Causes

In general, frontotemporal dementia is caused by degeneration of nerve cells in the frontal and temporal regions of the brain. FTD can be caused by mutations in different genes, but about half of all FTD cases have no family history of dementia. Frontotemporal lobar degeneration is categorized by accumulation in the brain of a protein called tau and the protein TDP-43. Some cases of FTD show abnormal tau protein-filled structures on the affected parts of the brain.

Frontotemporal Dementia Symptoms

Symptoms of frontotemporal dementia generally occur in younger patients in their 50s and 60s, and it is believed to account for 10% to 15% of all dementia cases. Behavioral changes appear early on in the disease with FTD, differing from the late onset of Alzheimer’s disease. Patients may show extreme behavioral changes such as inappropriate actions, loss of empathy, lack of judgment, apathy, repetitive compulsive behavior, a decline in personal hygiene, changes in eating habits, and lack of awareness. Patients may also suffer from impairment or loss of speech and language difficulties. Movement problems are also symptoms of FTD, but they typically occur in rare subtypes of FTD.

Frontotemporal Dementia Treatment and Prognosis

Frontotemporal dementia cannot be cured and there is no effective way to slow its progression. There are medications that can help manage the symptoms. Antidepressants and antipsychotics may help patients ease their symptoms.

After diagnosis, people with FTD typically live 6 to 8 years. Towards the final stages of the disease, the symptoms get worse and 24-hour care is required.

HIV-associated Dementia (HAD)

HIV-associated dementia (HAD), also called AIDS-dementia complex (ADC), is a brain disorder caused by infection with human immunodeficiency virus (HIV), the virus that causes AIDS. HIV may damage the brain cells by damaging nerve cells with viral proteins or by infecting inflammatory cells in the brain and spinal cord. The exact cause is unknown.

The main symptoms of HAD include impaired memory, lack of concentration, withdrawal from social activities, and speech difficulties. Medications to treat HIV/AIDS may delay the onset of the dementia symptoms. Highly active antiretroviral therapy (HAART) is effective in controlling HIV infection and protects many people from developing HAD.

Huntington’s Disease

Huntington’s disease is a genetic disorder that affects a person’s ability to think, feel, and move.

Huntington’s Disease Causes

Huntington’s disease is passed from parent to child through a mutation in a normal gene, which causes the degeneration of nerve cells in certain areas of the brain. Huntington’s disease targets cells within the basal ganglia, which coordinate movement and other important functions.

Huntington’s Disease Symptoms

Huntington’s disease symptoms may include the following:

  • Abnormal movements
  • Decline cognitive skills
  • Irritability, depression
  • Anxiety

Some patients may progress to show psychotic behavior.

Huntington’s Disease Treatment and Prognosis

There is no treatment available to stop or slow the progression of Huntington’s disease. Doctors may prescribe medications to help treat the emotional and movement problems associated with Huntington’s disease. Huntington’s disease begins earlier in life than other types of dementia, typically between the ages of 30 to 50. Life expectancy after the onset of symptoms is between 10 to 15 years.

Dementia Pugilistica

Boxer’s syndrome, or dementia pugilistica, is a form of chronic brain injury that occurs in many athletes (particularly boxers) who experience constant blows to the head.

Dementia Pugilistica Causes

Dementia pugilistica is caused by repetitive head trauma. Its name comes from symptoms experienced by boxers who have had years of being punched in the head.

Dementia Pugilistica Symptoms

Primary symptoms – which may not develop for years after the trauma – include the following:

  • Slurred speech
  • Poor motor coordination
  • Physical tremors
  • Difficulty walking
  • Patients may also experience memory problems.

Dementia Pugilistica Treatment

There is no treatment available to stop or slow progression of dementia pugilistica. Many of the medications used for the treatment of Alzheimer’s disease can also be used by dementia pugilistica patients.

Corticobasal Degeneration (CBD)

Corticobasal degeneration (CBD) is a loss of nerve cells (atrophy) in the cerebral cortex and the basal ganglia areas of the brain. CBD shares similar symptoms of Parkinson’s disease.

Corticobasal Degeneration Causes

Researchers believe that many different factors contribute to the cause of corticobasal degeneration. Genetic mutations, factors related to aging, and environmental factors may play a role in the development of CBD.

Corticobasal Degeneration Symptoms

Symptoms of corticobasal degeneration have features of parkinsonism (poor coordination, muscle rigidity, and shaking), as well as Alzheimer’s disease (memory loss, speech difficulty, and trouble swallowing). Patients with CBD deteriorate to the point where they can no longer care for themselves, and often die from secondary medical issues such as pneumonia or severe infection (sepsis).

Corticobasal Degeneration Treatment and Prognosis

There is no treatment that can stop or slow the progression of corticobasal degeneration. Certain medications can help treat the symptoms of CBD. This progressive disorder worsens over the course of 6 to 8 years due to degeneration of multiple brain areas.

Creutzfeldt-Jakob Disease (CJD)

Creutzfeldt-Jakob disease (CJD) is a type of human and animal disease known as transmissible spongiform encephalopathies (TSEs). It is in the same family of diseases as bovine spongiform encephalopathy (BSE, or “mad cow” disease). There are three main types of CJD: sporadic, familial, and infectious. Eighty-five percent of cases are sporadic, with no known cause. Familial cases account for 10% to 15% and are genetically passed on to family members. The remaining cases are infectious, resulting from exposure to an external source of the abnormal prion protein, such as in BSE.

 

Creutzfeldt-Jakob Disease Causes

Creutzfeldt-Jakob disease is thought to be caused by an abnormal protein called a “prion.” CJD is known as a prion disease and scientists believe that prions can unfold into abnormal three-dimensional shapes. This change triggers prion protein in the brain to fold into the same abnormal shape. These shapes in the brain end up destroying brain cells, but further research is needed.

Creutzfeldt-Jakob Disease Symptoms

Common symptoms of Creutzfeldt-Jakob disease include the following:

  • Depression
  • Agitation, apathy, and mood swings
  • Worsening confusion, disorientation, and memory problems
  • Difficulty walking
  • Muscle stiffness

Creutzfeldt-Jakob Disease Treatment and Prognosis

There is no treatment that can stop or slow the progression of Creutzfeldt-Jakob disease. Therapy and medications may help patients cope with their symptoms. It is estimated that 90% of people diagnosed with CJD will die within the first year.

Dementia in Children

Dementia can also occur in children. Though rare, there are some disorders that can cause the disease in pediatric patients including Niemann-Pick disease, Batten disease, Lafora body disease, and certain types of poisonings.

Niemann-Pick disease is inherited and is caused by specific gene mutations. Niemann-Pick disease is a group of inherited disorders that cause

s problems metabolizing cholesterol and other lipids, which leads to excessive amounts of other lipids to accumulate in the brain.

Batten disease is a fatal, hereditary disorder of the nervous system. Over time, children affected with Batten disease will suffer from mental impairment, seizures, and progressive loss of sight and motor skills.

Children with Lafora body disease will have seizures, rapidly progressive dementia, and movement problems.

Surprising Causes of Dementia

Many other conditions can cause dementia, including:

Low oxygen in the blood (anoxia/hypoxia), either from a specific incident (heart attack, stroke, surgical complications), or chronic disease (heart disease, asthma, COPD/emphysema) can cause damage to brain tissue.

Acute infections such as meningitis, encephalitis, untreated syphilis, and Lyme disease.

Brain tumors or metastases from other cancers in the body.

Thiamine (vitamin B1), B6, or B12 deficiencies, and severe dehydration.

Acute traumatic injury to the brain such as a subdural hematoma.

Side effects from medications taken for other medical conditions.

Electrolyte abnormalities.

Poisoning such as exposure to lead, other heavy metals, alcohol, recreational drugs, or other poisonous substances.

Brain Conditions that Mimic Dementia

Though many conditions may have similar symptoms to dementia, not all are considered to be dementia. These include:

  • Depression
  • Delirium
  • Age-related cognitive decline
  • B12 deficiency
  • Reactions to drugs (recreational or prescription)

What Causes Dementia?

All forms of dementia are the end result of either cell degeneration and death, or abnormalities impeding communications between brain cells (neurons). In many of the common types of dementia, abnormal proteins (or abnormal amounts of normally-occurring proteins) are found in the brain tissue on the microscopic level. It is unknown if these proteins cause dementia or if they result from the diseases themselves. While some types of dementia are hereditary

Is Dementia Hereditary?

Genes can play a role in the development of dementia, but patterns of inheritance dramatically vary. In some cases, Alzheimer’s disease starts early and occurs often in some families. This is known as early-onset familial Alzheimer’s disease. Researchers have found that many of the family members affected have a mutation in genes on chromosome 1 and 14. The pattern in which Alzheimer’s affects families is still uncertain. However, several risk factors for developing some types of dementia have been identified. These factors include:

  • Age
  • Genetics
  • Smoking and alcohol use
  • Atherosclerosis (hardening of arteries)
  • High cholesterol
  • Plasma homocysteine
  • Diabetes
  • Mild cognitive impairment
  • Down syndrome

Dementia Tests for Diagnosis

Most often, dementia is diagnosed by exclusion, which means doctors rule out other conditions that can cause the symptoms that resemble dementia. Doctors will use multiple tests to conclude whether or not a patient has dementia.

Tests to diagnose dementia include:

  • Physical examination with detailed neurological testing
  • Cognitive and neuropsychological tests
  • Brain scans (CT scans and MRI scans)
  • Blood tests, urinalysis, toxicology screen, thyroid tests
  • Psychiatric evaluation
  • Genetic testing

Dementia Treatment

There is no known cure for dementia, but many patients may benefit from combination treatments.

Medications for Alzheimer’s disease and some other forms of dementia can improve symptoms and slow the progression of the disease.

Cognitive training, such as memory training, note-taking, and computerized recall devices can aid in memory.

Behavior modification can help control behaviors that may put the patient in danger.

Medications for Alzheimer’s Disease

Most drugs approved by the U.S. Food and Drug Administration (FDA) to treat Alzheimer’s disease are called cholinesterase inhibitors. These drugs temporarily improve or stabilize memory and thinking skills in some individuals. These drugs include:

  • donepezil (Aricept)
  • rivastigmine (Exelon)
  • galantamine (Razadyne – previously called Reminyl)
  • tacrine (Cognex) – not used much due to side effects

Another drug is memantine hydrochloride (Namenda XR), an orally active NMDA receptor antagonist used to treat moderate to severe Alzheimer’s disease. Doctors may also prescribe other drugs, such as anticonvulsants, sedatives, and antidepressants to treat problems that may be associated with dementia such as insomnia, anxiety, depression, and sleep disorders.

Medications for Vascular Dementia

Because vascular dementia is caused by the death of brain tissue and atherosclerosis, there is no standard drug treatment for it. Drugs used to treat other atherosclerotic vascular diseases such as cholesterol medications, blood pressure medications, and anti-blood clotting medications may be used to slow the progression of vascular dementia. In some cases, cholinesterase inhibitors and antidepressants may help improve symptoms associated with vascular dementia.

Medications for Other Dementias

For the rarer forms of dementia, there are no standard medical treatments. Cholinesterase inhibitors, such as those used to treat Alzheimer’s disease, may reduce behavioral symptoms in some patients with Parkinson’s dementia. Frequently, medications are given to patients with dementia to relieve specific symptoms associated with their disorder. Doctors may prescribe other drugs, such as anticonvulsants, sedatives, and antidepressants to treat problems that may be associated with dementia such as insomnia, anxiety, depression, and sleep disorders.

Dementia Prevention

Further research is still needed in order to determine if dementia can be prevented. In some people, moderating known risk factors for dementia may help prevent or delay the onset of the disease.

Dementia Risk Factors

  • Keeping glucose levels under control
  • Keeping healthy cholesterol levels
  • Exercising
  • Maintaining healthy blood pressure
  • Maintaining a healthy weight
  • Quitting smoking and moderating alcohol consumption
  • Keeping the mind active and engaged with intellectually stimulating activities
  • Sleeping about 8 hours each night

Dementia Care

Patients with moderate and advanced dementia cannot adequately care for themselves and usually require around-the-clock care. Patients often do best when they are able to remain in a familiar environment such as their own home, when possible.

The patient’s environment should be made safe by following safety measures as recommended by the Alzheimer’s Association:

  • Lock any dangerous cabinets
  • Have working fire extinguishers, smoke detectors, and carbon monoxide detectors
  • Keep walkways well-lit and free of clutter to avoid tripping hazards
  • Remove or disable guns
  • Keep medications locked away
  • Turn hot water heater to 120 degrees or lower to prevent scalding injuries
  • Limit visitors
  • Limit noise and stimulation such as radios and televisions
  • Keep areas safe and free of clutter
  • Keep familiar objects nearby and in predictable places
  • Follow a set routine
  • Have calendars and clocks available to aid the patient’s memory
  • Engage in intellectually stimulating activities that the person is able to participate in

Exercise and Dementia Treatment

An active lifestyle can have a significant impact on the well-being of dementia patients. Not only does exercise benefit the patient physically, but mentally as well. Patients throughout all stages of dementia can benefit from physical activities such as walking, gardening, or dancing. It is important to ease into exercise if the patient does not take part in regular exercise. Exercise for dementia patients is important for the following reasons:

  • Improves the health of the heart and blood vessels (reduces the risk of high blood pressure and heart disease)
  • Reduces the risk of some types of cancer, stroke, and type 2 diabetes
  • Improves ability to complete daily tasks
  • Reduces the risk of osteoporosis
  • Reduces the risk of falling
  • Improves cognition
  • Improves sleep
  • Provides opportunities for social interaction
  • Improves self-esteem, mood, and confidence

Should I Be Driving?

It is very important to assess a patient’s driving skills if you are unsure if they are able to drive safely. Evaluations are available at the State Departments of Motor Vehicles (DMV). However, driving with dementia can be unsafe for both the driver, passengers, and those they share the road with. The patient with dementia may have slower reaction times, and can easily get confused or lost. It is up to the patient’s family and caregivers to ensure the patient does not have the opportunity to drive a car when they are no longer able to drive.

Dementia Research

Research on dementia is ongoing. There is a lot of focus on new treatments to slow the progression of cognitive dysfunction. Other research is aimed at decreasing the progression and damage to the brain due to abnormal proteins (tau and beta-amyloid). Researchers are also trying to identify the genes that may contribute to Alzheimer’s disease and develop drugs to modify these genes. Another area of research is trying to identify causes and treatments for inflammation to the brain, which is a key factor in Alzheimer’s dementia. Research into the brain cells’ utilization of insulin may lead to novel treatments for dementia.
