Non-drug based treatments for Alzheimer's disease
Non-medication based treatments include maximizing patients' opportunities for social interaction and participating in activities such as walking, singing, dancing that they can still enjoy. Cognitive rehabilitation, (whereby a patient practices on a computer program for training memory), may or may not be of benefit. Further studies of this method are needed.
Treatment of psychiatric symptoms in Alzheimer's disease
Symptoms of Alzheimer's disease include agitation, depression, hallucinations, anxiety, and sleep disorders. Standard psychiatric drugs are widely used to treat these symptoms although none of these drugs have been specifically approved by the FDA for treating these symptoms in patients with Alzheimer's disease. If these behaviors are infrequent or mild, they often do not require treatment with medication. Non-pharmacologic measures can be very useful.
Nevertheless, frequently these symptoms are so severe that it becomes impossible for caregivers to take care of the patient, and treatment with medication to control these symptoms becomes necessary. Agitation is common, particularly in middle and later stages of Alzheimer's disease. Many different classes of agents have been tried to treat agitation including:
- mood-stabilizing anticonvulsants,
- trazodone (Desyrel),
- anxiolytics, and
Studies are conflicting about the usefulness of these different drug classes. It was thought that newer, atypical antipsychotic agents such as clozapine (Clozaril), risperidone (Risperdal), olanzapine (Zyprexa, Zydis), quetiapine (Seroquel), and ziprasidone (Geodon) might have advantages over the older antipsychotic agents because of their fewer and less severe side effects and the patients' ability to tolerate them. However, more recent studies have not demonstrated superiority of the newer antipsychotics. Some research shows that these newer antipsychotics may be associated with increased risk of stroke or sudden death than the older antipsychotics, but many physicians believe this question is still not resolved.
Apathy and difficulty concentrating occur in most Alzheimer's disease patients and should not be treated with antidepressant medications. However, many Alzheimer's disease patients have other symptoms of depression including sustained feelings of unhappiness and/or inability to enjoy their usual activities. Such patients may benefit from a trial of antidepressant medication. Most physicians will try selective serotonin reuptake inhibitors (SSRIs), such as sertraline (Zoloft), citalopram (Celexa), or fluoxetine (Prozac), as first-line agents for treating depression in Alzheimer's disease.
Anxiety is another symptom in Alzheimer's disease that occasionally requires treatment. Benzodiazepines such as diazepam (Valium) or lorazepam (Ativan) may be associated with increased confusion and memory impairment. Non-benzodiazepine anxiolytics, such as buspirone (Buspar) or SSRIs, are probably preferable.

Difficulty sleeping (insomnia) occurs in many patients with Alzheimer's disease at some point in the course of their disease. Many Alzheimer's disease specialists prefer the use of sedating atypical antidepressants such as trazodone (Desyrel). However, other specialists may recommend other classes of medications. Sleep improvement measures, such as sunlight, adequate treatment of pain, and limiting nighttime fluids to prevent the need for urination, should also be implemented.
