Alzheimer's Disease

content developed with: http://www.clevelandclinic.org/

Alzheimer's disease (AD) gets worse over time, and the course of the disease varies from person to person. Some people have the disease for only the last five years of their lives, while others may have it for as long as 20 years. The most common cause of death in people with Alzheimer's disease is infection.

In managing the disease, physical exercise and social activity are important, as are proper nutrition, health maintenance, and a calm and well-structured environment.

For people who have been diagnosed with Alzheimer's:

Practical tips for taking care of someone with Alzheimer's:

Help for caregivers:

The economic and social burden of AD is very high; it is estimated that $80 billion to $100 billion is spent annually on the care of AD patients, and the cost per family is over $200,000 for each affected patient. Caregivers spend an average of 70 to 100 hours per week providing care and are more likely to require medical care themselves, including treatment for depression.

What to expect

When you get an illness like bronchitis or the flu, you know you will be feeling better and functioning normally within a week or so. Alzheimer's disease is different. It will never go away and can change your life and lifestyle in many ways.

Disability and fatigue may become a frequent part of your day. Physical and mental changes from Alzheimer's disease may occur and affect your mood and even your appearance. These changes may diminish your positive self-image. When you don't feel good about yourself, you may prefer isolation and withdraw from friends and social activities.

Alzheimer's disease also can influence your ability to function and get around at home. Confusion, as well as impaired judgment and disorientation, may require you to modify your work activities and environment. Decreased work ability and the increasing cost of care can lead to financial difficulties.

Specific tasks may take much longer to accomplish. You may need the help of your spouse, a relative, or a home healthcare provider. As your life changes, you may feel a loss of control and more anxious from the uncertainty of what lies ahead.

Stress can build and influence how you feel about life. Prolonged stress can lead to frustration, anger, hopelessness, and, at times, depression—all of which can worsen the symptoms of Alzheimer's disease. The person with the illness is not the only one affected. Family members are also influenced by the persistent health changes of a loved one.

Getting help

Alzheimer's disease, like many other chronic illnesses, will affect you both physically and mentally. It is important to realize that you are not alone and that if you feel you need help coping, you should consider seeking counseling.

The decision to seek counseling is an important step. Too often, people don't get help because they feel guilt, shame, or embarrassment. By deciding to get help, you have made a choice to feel better and to improve your life. Taking action early will enable you to understand and deal with the many effects of a chronic illness. Learning to manage stress will help you to maintain a positive physical, emotional, and spiritual outlook on life. If depression is present, medications other than those treating the physical illness may be ordered to help lift your mood.

Although no cure for Alzheimer's disease is now available, planning and medical/social management can help ease the burden on both patients and family members. Physical exercise, good nutrition, activities, and social interaction are important. A calm, structured environment also may help the person with Alzheimer's disease to continue functioning as long as possible.

Your healthcare provider can refer you to a mental healthcare professional, who could be a family therapist, social worker, psychologist, psychiatrist, or other professional. First, you will receive an "assessment," a review of your mental health. The assessment is used to diagnose the problem and determine the best treatment. You will be asked to describe why you want counseling, any symptoms you have (emotional, mental, and physical), and your medical history. You may be given a question-and-answer survey.

Once you complete the assessment, a treatment plan can be chosen. At this time, you and your counselor can discuss:

Early-onset disease

People with early-onset Alzheimer's disease must understand that life is not over. While it's true that your life will change, particularly as the disease progresses, there are things you can do to maintain a meaningful and productive life. It is especially important to continue with activities and interests you can still enjoy, and take comfort in the support of friends and family.

Yourself

Family and friends

Career

Financial and legal matters

Legal issues

As a caregiver, you should begin making legal preparations soon after your loved one has been diagnosed with a serious illness. People with Alzheimer's disease and other long-term illnesses may have the capacity to manage their own legal and financial affairs right now. As these diseases advance, however, the patients will need to rely on others to act in their best interests. This transition is never easy, but advance planning allows patients and their families to make decisions together for what may come.

A caregiver of an individual who no longer has the legal capacity to execute powers of attorney or trusts may have to become that individual's guardian or conservator. A guardian has the legal authority to make decisions about the lifestyle and well-being of another person. The decisions a guardian may make include where a person may live, what care and medical treatment will be provided, and what religious and educational activities will be made available. A conservator has legal authority to manage another person's financial affairs.

If the person being cared for has the legal capacity—the level of mental functioning necessary to sign official documents—he should actively participate in legal planning. Clearly written legal documents that outline your loved one's wishes and decisions are essential. These documents can authorize another person to make healthcare and financial decisions, including plans for long-term care.

To give your loved one the best care possible, obtain legal advice and services from an attorney. If the person you're caring for is age 65 or older, consider hiring an attorney who practices elder law, a specialized area of law focusing on issues that typically affect older adults. If you cannot afford an attorney, legal forms can be accessed through resources including books and the Internet. Legal issues may be discussed with a social worker or clergy free of charge.

Legal documents

As you plan for the future, the following documents may be important:

Dealing with behavioral changes

Caring for a loved one with Alzheimer's disease poses many challenges for the caregiver—particularly as the disease progresses and your loved one's ability to communicate declines.

The changes in the brain that are associated with Alzheimer's disease can lead to unusual and unpredictable thinking and behavior. For example, your loved one may become anxious around family members, neighbors, or friends whom he or she may not recognize or in situations that stray from the normal routine. The person with Alzheimer's disease also may become suspicious and suffer from delusions. He or she may begin to withdraw from social interaction, wander, become aggressive, and/or become angry and irritable.

In some cases, behavioral problems—especially physical aggressiveness and delusions—may require treatment with medications, such as antianxiety or antipsychotic drugs. However, these drugs can have negative side effects, including drowsiness and depression, and can further affect memory.

Following are some tips to help you manage the changes in thinking and behavior that often accompany Alzheimer's disease:

Personal care

People with Alzheimer's disease have special needs that can pose unique challenges for their caregivers. Depending on their level of independence, people with Alzheimer's disease may need help with personal care activities, including eating, bathing, shaving, and using the toilet. To assist with these activities, caregivers need knowledge, skill, and patience.

Following are some tips for caring for your loved one's personal needs:

General tips

Bathing

Hair care and shaving

Dental care

Using the toilet

Maintaining good nutrition

For a person with Alzheimer's disease, the illness itself or associated depression can affect the desire and ability to eat. Good nutrition is important for people with Alzheimer's disease. In fact, poor nutrition can worsen some symptoms of dementia, such as listlessness and confusion.

If poor appetite is becoming a concern for your loved one, try following these nutrition guidelines.

General guidelines:

Meal guidelines:

Snack guidelines:

Dining guidelines:

Exercise

For people with Alzheimer's disease, physical activity should be continued for as long as possible.

Exercise offers many benefits for people with Alzheimer's disease, including improved strength, endurance, and cardiovascular fitness. Exercise helps people with Alzheimer's disease preserve motor skills and improve balance, which in turn can help prevent serious injury from falls. Exercise also can increase energy, promote a normal day and night routine, and help to improve mood. Further, exercise increases circulation and can help improve mental clarity. Repetitive exercises—including walking, indoor bicycling, and activities such as folding laundry—may decrease anxiety in people with Alzheimer's disease because they don't have to make decisions about the activity or remember what to do next.

The type and intensity of exercise appropriate for someone with Alzheimer's disease depends on the person's degree of impairment. People in the early stages of the disease may enjoy exercises such as walking, bowling, dancing, golf, and swimming, although supervision may be necessary. Greater supervision may be required as the disease progresses, and activities that could lead to injury should be avoided. Most of all, select a hobby or activity you enjoy, and stick with it. Some suggestions include golfing, walking, swimming, water aerobics, yoga, and tai chi.

It is important to talk to your doctor before beginning any exercise program. There may be other factors—such as osteoporosis, a heart condition, or a balance problem (possibly due to medication)—that could limit or restrict activity.

Your doctor may make recommendations about:

Sundown syndrome

Sundown syndrome—also called sundowning or sunsetting—is a behavior common in people with Alzheimer's disease. It describes the episodes of confusion, anxiety, agitation, or disorientation that often occur at dusk and into the evening hours. The episodes may last a few hours or throughout the night.

While the exact cause of sundown syndrome is not known, experts believe there are several contributing factors. These include physical and mental exhaustion (after a long day) and a shift in the internal body clock caused by the change from daylight to dark. Some people with Alzheimer's disease have trouble sleeping at night, which may contribute to their disorientation. Medication that can cause agitation or confusion also may be a contributing factor to this syndrome.

Sundown syndrome can be draining for the person with Alzheimer's disease and his or her caregivers. Here are some suggestions for helping a loved one with sundown syndrome:

Safety

Because activities of daily living—including eating, bathing, grooming, dressing, and using the toilet—can become more difficult for people with Alzheimer's disease, it's important to modify the environment to make it as easy as possible for the person with the disease to live and function.

A careful evaluation of the home, especially the physical layout and the services that will be available to the person for support, is essential. Some patients can continue to be independent in their living situation if they have complete support services. Things that should be evaluated include safe operation of the stove or oven, and bathroom/bathtub or shower use. Therapists and social service workers who are professionally trained to look for potential hazards can perform a full home safety evaluation.

Bathroom: The bathroom can be a dangerous place for a person with Alzheimer's disease. As the person's ability to function decreases, it may become necessary to install grab bars in the shower or fold-down shower seats. Also, be sure to use nonslip floor mats and slip-resistant appliqués or tiles in the shower or tub.

Furniture: Simplify furniture arrangements. Make it as easy as possible for the person with Alzheimer's disease to navigate a room and get from point A to point B. Move or remove objects, such as a loose throw rug, that could be a tripping hazard.

Lighting: Be sure there is sufficient lighting. As people get older, they require two to three times the amount of light they needed when they were younger. Add the confusion associated with Alzheimer's disease, and you can understand how important it is to have enough light. However, too much light, especially when it causes glare, can be distracting and irritating.

See our section on general safety tips.

General tips

Have emergency numbers (police, fire, poison control, and a neighbor's phone number) readily available in case of emergency. Suggestion: Write these numbers on a sticker, and put it on the receiver.

Have at least one phone located where it is always accessible. The person with Alzheimer's could keep a cordless phone in his or her pocket—this is especially important if he or she falls and can't get up to use the phone.

Make sure smoke detectors work properly, and remember to change the batteries frequently. Use a carbon monoxide detector.

Avoid the use of space heaters and electric blankets; these are fire hazards. If they must be used, follow the manufacturer's safety instructions, and keep them on a sturdy surface away from rugs, curtains, furniture, or papers.

Consider installing a medical alert or personal alarm system for emergencies. Professional systems link directly to a representative 24 hours a day, seven days a week. A person who has an immediate medical problem simply pushes a button on a special device worn around the wrist or neck, and a signal for help is immediately sent.

Driving

A means of transportation is an essential ingredient in maintaining independence. It is especially important as people grow older. Transportation allows them to run errands, go to doctor's appointments, and socialize with family and friends. However, there will come a time when your loved one's driving skills will decline because of age, disability, or both. Once this occurs, it is important to assess whether or not it is still safe for your loved one to drive. Some warning signs of a possible decline in driving skills include:

If you notice some of the above declines in driving skills in your loved one, this does not mean the car must be taken from him or her immediately. The first step a caregiver must take with the patient is to talk about the signs of possible decline that are of concern. During this talk, the caregiver can make suggestions such as encouraging his or her loved one to avoid driving at night, during rush hour, or when weather makes the roads slick. Another approach can be recommending a medical and/or eye exam to see if any of the above signs can be corrected.

Research suggests that even mild Alzheimer's disease is associated with an increased risk of accidents. It is important to check with your state's Department of Motor Vehicles to find out the procedure for evaluating the patient's driving ability. Many areas will perform a thorough "driver safety evaluation" to determine whether it is safe for the person to continue driving. If there is any impairment noted in visual or spatial abilities or judgment, the person with Alzheimer's disease should not be driving.

If the caregiver determines that a loved one should no longer be driving, alternate means of transportation should be sought. Often this means that the caregiver must provide transportation. However, it is not always possible or practical to provide transportation when needed.

Resources

To find information on transportation for the elderly that is available in your area, one of the best places to start is your local area agency on aging. There are over 650 area agencies on aging throughout the United States. These offices are part of the Administration on Aging (www.aoa.gov), an agency of the U.S. Department of Health and Human Resources.

These agencies have information available to older persons and their caregivers about transportation services, as well as other services available in the community. They also monitor and support specialized services for elderly in the community and ensure that services are delivered to those elderly in need.

Other references for available transportation include:

Travel

The most important thing to do when traveling with someone with Alzheimer's disease is to plan ahead and try to anticipate the person's needs so you'll be ready for any changes or problems. As you plan, be sure to consider the stage of the person's illness and any behaviors that may be affected by traveling away from home. You may want to try taking a short trip to see how he or she reacts to traveling. Here are a few other tips to consider:

Caregiver's role

While many patients retain their independence for a while after being diagnosed with Alzheimer's disease, some need more help with daily activities. For others, the diagnosis may come after weeks or months of coping with symptoms that did not have a name. At some point, though, a caregiver is needed. A caregiver's role is multifaceted:

The most effective caregiver is well informed, prepared, and willing to ask for help and support from all resources that are available.

There are some unique challenges that a patient with Alzheimer's disease confronts. First, the disease is quite variable. There may be times when the patient can function almost normally and then other times when the patient may be very dependent. This is a natural part of the disease. Also, the patient's response to medications may fluctuate. There is a natural tendency for a caregiver to suspect that the patient might be unnecessarily demanding or manipulative. The caregiver may see the patient functioning normally but then assume that the patient should always be able to function normally.

Depression is very much a part of the disease. Alzheimer's symptoms and disability can be made worse by depression, so it is important to recognize the signs and symptoms of depression and help your loved one seek treatment promptly.

Caregiver burnout

Caregiver burnout is a state of physical, emotional, and mental exhaustion that may be accompanied by a change in attitude—from positive and caring to negative and unconcerned. Burnout can occur when caregivers don't get the help they need or if they try to do more than they are able—either physically or financially. Caregivers who are burned out may experience fatigue, stress, anxiety, and depression. Many caregivers also feel guilty if they spend time on themselves rather than on their ill or elderly loved ones.

The symptoms of caregiver burnout are similar to the symptoms of stress and depression. They include:

Those who are already suffering from stress and depression should seek medical attention. Stress and depression are treatable disorders.

Caregivers often are so busy caring for others that they tend to neglect their own emotional, physical, and spiritual health. The demands on a caregiver's body, mind, and emotions can easily seem overwhelming, leading to fatigue and hopelessness—and, ultimately, burnout. Other factors that can lead to caregiver burnout include:
