Aged nervous tissue

Senile dementia/Alzheimer's type (SDAT)

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 environment.
• 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. Memantine (Namenda) is currently the only drug approved for the treatment of moderate-to-severe Alzheimer’s disease.

Other medicines include donepezil (Aricept), rivastigmine (Exelon), galantamine (Razadyne, formerly called Reminyl), and tacrine (Cognex). These drugs affect the level of a neurotransmitter in the brain called acetylcholine. They may cause nausea and vomiting. Tacrine also causes an elevation in liver enzymes and must be taken four times a day. It is now rarely used.

Aricept is taken once a day and may stabilize or even improve the person's mental capabilities. It is generally well tolerated. Exelon seems to work in a similar way. It is taken twice a day.

Other medicines may be needed to control aggressive, agitated, or dangerous behaviors. These are usually given in very low doses.

It may be necessary to stop any medications that make confusion worse. Such medicines may include pain killers, cimetidine, central nervous system depressants, antihistamines, sleeping pills, and others. Never change or stop taking any medicines without first talking to your doctor.
