People with Alzheimer’s disease and other forms of dementia can become restless, aggressive, or disruptive. They may believe things that are not true. They may see or hear things that are not there. These symptoms can cause even more distress than the loss of memory.
Doctors often prescribe powerful antipsychotic drugs to treat these behaviours:
If you are uncertain if your loved one is taking one of these medications, please ask their health care team. In most cases, antipsychotics should not be the first choice for treatment. Here’s why:

Consider antipsychotic drugs if:
Start the drug at the lowest possible dose. Caregivers and health professionals should watch the patient carefully to make sure that symptoms improve and that there are no serious side effects. The drugs should be stopped if they are not helping or are no longer needed.
Keep a daily routine. People with dementia often become restless or irritable around dinner time.
Help the person exercise every day. Physical activity helps use nervous energy. It improves mood and sleep.
Don’t argue with a person who’s distressed.
Plan simple activities and social time. Boredom and loneliness can increase anxiety. Adult daycare programmes can provide activities for older people. They also give caregivers a break.
It’s OK to ask questions
If you have questions about your symptoms or the medicines managing your symptoms, speak with your health professional.
