There is an association between bipolar disorder and dementia.

This difference is not substantial, and having bipolar disorder does not mean that you will definitely develop dementia.

Dementia starts during later adulthood, usually past age 65, and continues to worsen over the years.

Overlapping Symptoms

Bipolar disorder is a mood disorder.

Episodes of depression and mania or hypomania (less intense than mania) can cycle with unpredictable timing.

These conditions also contribute to dementia, especially vascular dementia and Alzheimers disease.

Dementia Treatments

If you develop dementia, you might take medication thats intended to slow neurodegeneration.

Neurodegeneration is the shrinking and death of brain cells, and its a major aspect of dementia.

Living with any psychiatric disorder, including a mood disorder, can increase your risk of medical conditions.

The reason for the increased risk is not completely known but is multifactorial.

There is a possible overlap of underlying causes, such as genetics or a history of adverse life experiences.

Lowering Your Risk

Managing bipolar disorder can reduce your risk of other illnesses, including dementia.

Summary

You might have an increased risk of developing dementia if you have bipolar disorder.

Genetic factors and lifestyle and health issues can contribute to the shared risk.

Taking care of your bipolar disorder and your overall health can reduce your risk of developing dementia.
