People with dementia often have behavioural problems that can be difficult for carers to manage. Antipsychotic drugs are often prescribed to control symptoms and assist with controlling difficult behaviour. Many people with dementia continue to take these drugs over long periods of time. This review investigates whether withdrawal of long-term antipsychotic treatment is feasible in older people with dementia suffering from behavioural symptoms (often called neuropsychiatric symptoms or NPS). These include agitation, aggression, hallucinations, anxiety, apathy, depression, delusions (beliefs that cannot be true), wandering, repeating of words or sounds, and shouting. Nine studies with 606 participants provided data for the review. Most of the participants were residents in nursing homes, but some were outpatients. The studies differed considerably in participants, methods and outcomes so that is was not possible to combine most of the data numerically.

The evidence suggests that older nursing home residents or outpatients with dementia can be withdrawn from long-term antipsychotics without detrimental effects on their behaviour. Caution is required in older nursing home residents with more severe NPS, as two studies suggest these peoples' symptoms might be worse if their antipsychotic medication is withdrawn. Moreover, one study suggested that older people with dementia and psychosis or agitation and a good response to their antipsychotic treatment for several months could relapse after discontinuation of their antipsychotic medication. We do not know if there are beneficial effects of withdrawal on intellectual processes, quality of life or ability to carry out daily tasks, or if the risk of harmful events is reduced by drug withdrawal. One study suggests that older people with dementia who continue to take antipsychotics might die earlier.
