ALZHEIMER’S DISEASE

Watching a loved one live their lives with Alzheimer is heart breaking

Rendering Proper Care IT IS ONE OF THE HARDEST JOBS IMAGINABLE IT REQUIRES AN ABUNDANCE OF EMOTIONAL AND PHYSICAL ENERGY ACCEPTNCE OF HELP AND TAKING CARE OF YOURSELF IS

What is Alzheimer’s Disease  Is

a progressive, irreversible brain disorder with no known cause or cure  It attacks and slowly erases the minds of its victims  Symptoms of the disease include memory loss, confusion, impaired judgment, personality changes, disorientation, and loss

ALWAYS FATAL

Most common form of irreversible dementia

EPIDEMIOLOGY  Approximately

100,000 victims die and 360,000 new cases of Alzheimer's disease are diagnosed each year  In the U.S. alone, it is estimated that by 2050, 14 million Americans will have this disease.  America is not all alone in this malady.

 In

every nation where life expectancy has increased, so has the incidence of Alzheimer's disease  Alzheimer's disease is becoming tragically common  It is estimated that by 2020, 30 million people will be affected by this devastating disorder worldwide and by 2050, the

 The

disease usually begins after age 60, and risk goes up with age  While younger people also may get AD, it is much less common  About 5 percent of men and women ages 65 to 74 have AD, and nearly half of those age 85 and older may have the disease  AD is not a normal part of aging

  

AD has a long history Although it was only in 1906 when the disease has acquired a name. AD is named after Dr. Alois Alzheimer, a German doctor.



In 1906, Dr. Alzheimer noticed changes in the brain tissue of a woman who had died of an unusual mental illness.



He found abnormal clumps (now called amyloid plaques) and tangled bundles of fibers (now called neurofibrillary tangles).

 Scientists

also have found other brain changes in people with AD.

 Nerve

cells die in areas of the brain that are vital to memory and other mental abilities.



There also are lower levels of some of the chemicals in the brain that carry messages back and forth between nerve cells

ETIOLOGY  Scientists

do not yet fully understand what causes AD.

 There

probably is not one single cause, but several factors that affect each person differently.



Age is the most important known risk factor for AD.

 The

number of people with

RISK FACTORS  Family

history

– Scientists believe that genetics may play a role in many AD cases. – For example, familial AD, a rare form of AD that usually occurs between the ages of 30 and 60, is inherited. – The more common form of AD is known as late-onset. It occurs later in life, and no obvious inheritance pattern is seen.

– However, several risk factor genes may interact with each other to cause the disease. – The only risk factor gene identified so far for late-onset AD, is a gene that makes one form of a protein called apolipoprotein E (apoE). – Everyone has apoE, which helps carry cholesterol in the blood. – It is likely that other genes also may increase the risk of AD or

PATHOLOGY

AMYLOID PLAQUES 







One of the hallmarks of Alzheimer's disease is the accumulation of amyloid plaques between nerve cells (neurons) in the brain. Amyloid is a general term for protein fragments that the body produces normally. Beta-amyloid is a fragment of a protein that is snipped from another protein called amyloid precursor protein (APP). In a healthy brain, these protein

NEUROFIBRILLARY TANGLES

Neurofibrillary tangles consist of insoluble twisted fibers that are found inside of the brain's cells.  They primarily consist of a protein called tau, which forms part of a structure called a microtubule.  The microtubule helps transport nutrients and other important substances from one part of the nerve cell to another.  In Alzheimer's disease, however, the tau protein is abnormal and the 

How the Brain and Nerve Cells Change During Alzheimer's Disease









The ability to recognize faces and to communicate is completely lost in the final stages. Patients lose bowel and bladder control, and eventually need constant care. This stage of complete dependency may last for years before the patient dies. The average length of time from diagnosis to death is 4 to 8

There is an overall shrinkage of brain tissue as Alzheimer's disease progresses.  In addition, the ventricles, or chambers within the brain that contain cerebrospinal fluid, are noticeably enlarged.  In the early stages of Alzheimer's disease, short-term memory begins to decline when the cells in the hippocampus, which is part of the limbic system, degenerate.  The ability to perform routine tasks also declines. As Alzheimer's disease spreads through the cerebral cortex (the outer layer of the brain), judgment declines, emotional outbursts may occur and language is impaired. 

DIAGNOSIS OF ALZHEIMER’S DISEASE

 An

early, accurate diagnosis of AD helps patients and their families plan for the future.  It gives them time to discuss care while the patient can still take part in making decisions.  Early diagnosis will also offer the best chance to treat the symptoms of the disease.







Today, the only definite way to diagnose AD is to find out whether there are plaques and tangles in brain tissue. To look at brain tissue, how-ever, doctors must wait until they do an autopsy, which is an examination of the body done after a person dies. Therefore, doctors can only make a diagnosis of "possible" or "probable" AD while the person is still alive.

TOOLS USED BY PHYSICIANS  questions

about the person’s general health, past medical problems, and the history of any difficulties the person has carrying out daily activities,  tests of memory, problem solving, attention, counting, and language,  medical tests—such as tests of blood, urine, or spinal fluid, and  brain scans.

DIFFERENTIAL DIAGNOSIS  For

example, thyroid problems, drug reactions, depression, brain tumors, and blood vessel disease in the brain can cause AD-like symptoms.  Some of these other conditions can be treated successfully.

DIFFERENTIAL DIAGNOSIS 

Mild cognitive impairment (MCI) – different from both AD and normal age-related memory change. – People with MCI have ongoing memory problems, but they do not have other losses like confusion, attention problems, and difficulty with language. – Study to learn whether early diagnosis and treatment of MCI might prevent or slow further memory loss, including the development of AD.

TREATMENT OF ALZHEIMER’S DISEASE

 



No treatment can stop AD. However, for some people in the early and middle stages of the disease, the drugs tacrine (Cognex), donepezil (Aricept), rivastigmine (Exelon), or galantamine (Reminyl) may help prevent some symptoms from becoming worse for a limited time. Another drug, memantine (Namenda), has been approved for treatment of moderate to severe AD.

 Also,

some medicines may help control behavioral symptoms of AD such as sleeplessness, agitation, wandering, anxiety, and depression.  Treating these symptoms often makes patients more comfortable and makes their care easier for caregivers.

 Developing

new treatments for AD is an active area of research.  Scientists are testing a number of drugs to see if they prevent AD, slow the disease, or help reduce symptoms.

 





ROLE OF ANTIINFLAMMATORY DRUGS There is evidence that inflammation in

the brain may contribute to AD damage. Some scientists believe that drugs such as nonsteroidal anti-inflammatory drugs (NSAIDs) might help slow the progression of AD. Although recent studies of two of these drugs, rofecoxib (Vioxx) and naproxen (Aleve), have shown that they did not delay the progression of AD in people who already have the disease. Now, scientists are studying the NSAIDs celecoxib (Celebrex) and naproxen to find out if they can slow the onset of the disease.

ROLE OF VITAMIN E  Research

has shown that vitamin E slows the progress of some consequences of AD by about 7 months.  Scientists now are studying vitamin E to learn whether it can prevent or delay AD in patients with MCI.

ROLE OF GINKGO BILOBA  Recent

research suggests that ginkgo biloba may be of some help in treating AD symptoms.  There is no evidence that ginkgo will cure or prevent AD.  Scientists now are trying to find out whether ginkgo biloba can delay or prevent dementia in older people.









ROLE OF HORMONE REPLACEMENT THERAPY Earlier studies had suggested that the

hormone replacement therapy that millions of women take after menopause may be protective against AD. However, the WOMEN Health Initiative clinical trial found an increased risk of AD in women taking hormones as compared with those taking an inactive pill. The trial used a commonly pre-scribed pill combining estrogens and progesterone. Further studies on estrogen alone and other hormone preparations, such as the estrogen patch, continue.

ISSUES ON CAREGIVING ALZHEIMER’S PATIENTS

ISSUE NUMBER 1

CAREGIVING IS A HEAVY BURDEN

The roles that family caregivers must accept can be overwhelming.  In addition to meeting the physical needs of the relative with Alzheimer's, such as helping with personal hygiene and dressing, preparing meals, and housekeeping, it is important to ensure that the person is stimulated by both social and physical activity.  The caregiver must also think to the future, plan for increasing custodial and medical care, and usually take over fiduciary responsibilities.  Faced with all these tasks, caregivers can 

ISSUE NUMBER 2

RESENTFULNESS OF THE CAREGIVER

Another danger for the overburdened caregiver is becoming resentful to the point of neglecting the care recipient's needs or engaging in abusive behavior-psychological or physical.  The National Elder Abuse Incidence Study reported that in one year, 1996, more than 550,000 persons age 60 or older had experienced some type of neglect or abuse, 90% at the hands of a family member.  Elderly persons with advancing Alzheimer's or other dementia are more vulnerable than most because they cannot understand what is happening to them, defend themselves, or communicate their 

THIRD ISSUE

CARE FOR THE CAREGIVERS THEMSELVES







Available to help the caregiver meet this need are numerous support services, many offered by volunteers through local chapters of the Alzheimer's Association, church groups, or other local service organizations. Of all services, respite care is probably the most important, for what the caregiver needs most is time away, whether for a few hours or a few days. For those who can afford it, residential

FOURTH ISSUE Accepting the role of caregiver to a person with Alzheimer's, with all its responsibilities as well as distasteful tasks, requires commitment and a capacity for caring.

RACIAL AND CULTURAL DIFFERENCES



A qualitative study conducted by Ana Ortiz et al among Latino and Irish American caregivers of demented elders in the Boston area showed how "ties to homelands and neighborhood institutions act as mediators and shapers of anticipatory grief, caregiver burdens, and caregiver resources, serving as a buffer against exhaustion and despair for some families (primarily the Irish American sample) and as an

INTERACTION ISSUES OF THE CAREGIVER WITH THE PATIENT







1. Arguments are useless and in fact,

make matters worse. Confusion memory loss and frustration are making the person behave irrationally and you can't "argue" them out of it. 2. Actions help when verbal communication may fail. Help the person by demonstrating what you mean or sometimes by starting him or her in the activity 3. Assume that people with Alzheimers may understand and hear what you say even if they are confused. Do not say things to others in front of them as

5. Appropriate activities help people with Alzheimer's pass the time meaningfully and productively and reduce agitation, boredom , daytime sleeping and depression 6. Agitation can be alleviated when the caregiver remains calm, reassuring and respectful of the person's feelings 7. Adults with disabilities are still adults. Mental level is not always equal to social level. 8. Adapt the task to fit the ability of the patient. Break down the activity into separate steps or simplify the

COPING MECHANISMS 

 



Family caregivers must learn how to cope with their burden of care, fears, depression, physical strain, and psychological stress. They need support. True care giving families share the burden, providing at least respite care and temporary or occasional help to the primary caregiver. If family help is not available, it is imperative that the caregiver

CREATIVE IDEAS IN CARING FOR ALZHEIMER’S PATIENTS

EARLY STAGE Individuals in this stage are often quite active, aware that they have AD and struggling to remain independent. Gifts that enhance independence or encourage activity are excellent choices.







  

Games - simple but familiar games, such as dominoes, large numbered cards, or bingo have the potential for quite a bit of enjoyment Tickets to a concert, musical, circus, or sporting event can be a fun choice. Remember, though, that your loved one may be overwhelmed by too much activity. Visit a shopping mall and "window shop," then have lunch or ice cream together. Limit your trips to no more than three hours. Frozen homemade meals can be reheated in a microwave and are especially good for couples. Collage - frame a collage of old family photos highlighting the major events in the person's life. Fruit basket or flowers - always a welcome gift.

MODERATE STAGE Persons with moderate stage AD will require more assistance, but still remain active. Wandering is frequently seen in the group, so exercise is important. Attention span varies; activities are best limited to about 15 minutes









Materials to sort - coins, a bag of buttons, or large beads can be fun to sort. Men might enjoy sorting keys, nuts and bolts, or cards better. Music, especially "old songs," often brings back wonderful memories. Check with record stores for remakes of older albums. A jewelry box with a variety of costume jewelry to rummage through is ideal. Low-cost items can be found at thrift shops and garage sales. Make inexpensive copies of the person's good jewelry for them to wear. If items are lost, the good jewerly will remain safe with the family. Basket of yarn or fabric - for rummaging and sorting. Be sure to include fabrics with different textures to stimulate the sense of touch. Taped church services - mid-stage dementia individuals may not attend church, but will enjoy the

LATE STAGE In the late stage of the disease, people with dementia do not have the capacity to deal with anything but the simplest of tasks. At this stage, they are "living in the past" and may believe that they are much younger and living in the home or community of their younger years. Attention span and understanding are both very poor.









Memory books - a gathering of old pictures and mementos from the person's past may allow them to think about and enjoy intact memories. Animals - many people with late-stage dementia still enjoy visits from dogs, cats, and other animals such as guinea pigs and rabbits. Box turtles are also a big hit, as well as bird watching. Be sure the larger animals are welltrained to handle certain behaviors of the late stage individual. Knee warmers - good for an inactive, wheelchair-bound person with late stage AD. Circulation is often poor at this stage, and the knee warmer or lap blanket helps conserve heat and reduce symptoms associated with poor circulation. Cuddle animals or dolls - many late stage dementia patients enjoy having a soft cuddle object to bring back

WHEN CARING FOR ALZHEIMER’S PATIENT’S WHAT IS IMPORTANT IS LOVE, UNDERSTANDING AND EMOTIONAL STRENGTH
