A large UK study found that the drug risperidone is linked to a higher risk of stroke in people with dementia. The findings challenge previous assumptions and raise concerns about how the medication is prescribed and monitored.

A recent study involving over 165,000 people with dementia has revealed that the drug risperidone is associated with a higher risk of stroke. Risperidone is often used to treat severe agitation or aggressive behavior in dementia patients who have not responded to non-drug approaches. The study found that even patients without a previous history of heart disease or stroke faced an increased risk of stroke when taking risperidone.

The researchers compared the health records of people with dementia who were prescribed risperidone with those who were not taking the drug. They found that the annual rate of stroke per 1000 person-years was higher among patients taking risperidone, even in those without a prior history of stroke or heart disease.

The study's findings highlight the difficult decisions faced by doctors and families when considering the use of risperidone to treat severe agitation. While the drug can be effective in reducing aggression and distress, it carries a higher risk of serious side effects like stroke.

Why It Matters

This research matters because it highlights the importance of informed decision-making when treating people with dementia. As India's population ages, understanding the risks and benefits of medications like risperidone is crucial for ensuring that patients receive the best possible care.
