Unfortunately, there is no cure for AD. The goals in treating AD are to:
- Slow the progression of the disease.
- Manage behavior problems, confusion, and agitation.
- Modify the home enviroment.
- Support family members and other caregivers.
The most promising treatments include lifestyle changes, medications, and antioxidant supplements like vitamin E and ginkgo biloba.
LIFESTYLE CHANGES
The following steps can help people with AD:
- Walk regularly with a caregiver or other reliable companion. This can improve communication skills and prevent wandering.
- Use bright light therapy to reduce insomnia and wandering.
- Listen to calming music. This may reduce wandering and restlessness, boost brain chemicals, ease anxiety, enhance sleep, and improve behavior.
- Get a pet dog.
- Practice relaxation techniques.
- Receive regular massages. This is relaxing and provides social interactions.
DRUG TREATMENT
Several drugs are available to try to slow the progression of AD and possibly improve the person's mental capabilities. These include donepezil (Aricept), rivastigmine (Exelon), galantamine (Razadyne, formerly called Reminyl), and tacrine (Cognex).
All of these drugs affect the level of acetylcholine (a neurotransmitter) in the brain and all have potential side effects, such as nausea and vomiting. Tacrine also causes an elevation in liver enzymes and must be taken four times a day. It is now seldom used.
Aricept is taken once a day and may stabilize or even improve the person's mental capabilities. It is generally well tolerated. Exelon, a new drug, shows a similar effectiveness and is taken twice a day.
Other medications may be required to control aggressive, agitated, or dangerous behaviors. These are usually given in very low doses, with adjustment as needed.
It may be necessary to stop any medications that worsen confusion. These may include pain killers, cimetidine, central nervous system depressants, antihistamines, sleeping pills, and others. Medications MUST NOT be stopped or changed without discussion with and direction from your doctor.
SUPPLEMENTS
Folate (vitamin B9) is critical to the health of the nervous system. Together with some other B vitamins, folate is also responsible for clearing homocysteine (a body chemical that contributes to chronic illnesses) from the blood. High levels of homocysteine and low levels of both folate and vitamin B12 have been found in people with AD. Although the benefits of taking these B vitamins for AD is not entirely clear, it may be worth considering them, particularly if your homocysteine levels are high.
Antioxidant supplements, like ginkgo biloba and vitamin E, scavange free radicals. These products of metabolism are highly reactive and can damage cells throughout the body.
Vitamin E dissolves in fat, readily enters the brain, and may slow down cell damage. In at least one well-designed study of people with AD who were followed for 2 years, those who took vitamin E supplements had improved symptoms compared to those who took a placebo pill. Patients who take blood-thinning medications like warfarin (Coumadin) may should talk to their doctor before taking vitamin E.
Ginkgo biloba is an herb widely used in Europe for treating dementia. It improves blood flow in the brain and contains flavonoids (plant substances) that act as antioxidants. Although many of the studies to date have been somewhat flawed, the idea that ginkgo may improve thinking, learning, and memory in those with AD has been promising. DO NOT use ginkgo if you take blood-thinning medications like warfarin (Coumadin) or a class of antidepressants called monoamine oxidase inhibitors (MAOIs).
If you are considering any drugs or supplements, you MUST talk to your doctor first. Remember that herbs and supplements available over the counter are NOT regulated by the FDA.
SUPPORT AT HOME
Someone with AD will need support in the home as the disease worsens. Family members or other caregivers can help by trying to understand how the person with AD perceives his or her world. Simplify the patient's surroundings. Give frequent reminders, notes, lists of routine tasks, or directions for daily activities. Give the person with AD a chance to talk about their challenges and participate in their own care.
OTHER PRACTICAL STEPS
The person with AD should have their eyes and ears checked. If problems are found, hearing aids, glasses, or cataract surgery may be needed.
Those with AD may have particular dietary requirements such as:
- Extra calories due to increased physical activity from restlessness and wandering.
- Supervised meals and help with feeding. People with AD often forget to eat and drink, and can become dehydrated as a result.
The Safe Return Program, implemented by the Alzheimer's Association, requires that a person with AD wear in identification bracelet. If he or she wanders, the caregiver can contact the police and the national Safe Return office, where information about the person is stored and shared nationwide.
Eventually, 24-hour monitoring and assistance may be necessary to provide a safe environment, control aggressive or agitated behavior, and meet physiologic needs. This may include in-home care, nursing homes, or adult day care.
