The decision to try medicine to treat behaviour problems in Alzheimer's disease is different for each person. The decision weighs the risks and benefits of these medicines. Your doctor can help you decide. Medicines for behaviour problems linked to dementia do not work very well for most people and may have serious risks.
Medicines can be used to treat behaviour problems caused by Alzheimer's disease and other diseases that cause dementia. They should be used only after other non-drug approaches have failed to improve a person's symptoms. Medicine may be needed when the person is in danger of harming himself or herself or others or when the caregiver is unable to deal with the situation using other means.
Antipsychotic medicines may help relieve more severe agitation or psychosis (disordered thought processes).
Examples of medicines sometimes used to treat hallucinations, paranoia, and severe agitation in people who have dementia include aripiprazole, haloperidol, and risperidone.
Advisories. Health Canada and the U.S. Food and Drug Administration (FDA) have issued advisories stating that people with dementia who use antipsychotics may die sooner than those who don't use these drugs.
Antianxiety medicines, including minor tranquilizers, relieve anxiety and mild agitation and may help calm the person. But they can cause drowsiness if the dose is too high. When minor tranquilizers are needed, short-term or occasional use often is better than continuous use.
Lorazepam and oxazepam are minor tranquilizers sometimes used to treat the symptoms of dementia. Another antianxiety medicine called buspirone also can be tried.
Anticonvulsant medicine, such as valproic acid, may be used to control agitation, violent behaviour, and mood swings caused by dementia.
Other medicines that may be used to treat agitation include antidepressants. Trazodone and serotonin reuptake inhibitors (SSRIs) such as citalopram, fluoxetine, and sertraline are examples. But research on the effectiveness of these medicines in Alzheimer's disease and other dementias is limited.
Health Canada and the U.S. Food and Drug Administration (FDA) have issued advisories on antidepressant medicines and the risk of suicide. Talk to your doctor about these possible side effects and the warning signs of suicide.
See Drug Reference for more information about all of these medicines. (Drug Reference is not available in all systems.)
