Dementia is the severe loss of cognitive function (the ability to think, remember, or reason) that affects a person's daily life and activities. Signs and symptoms of dementia occur when once-healthy neurons (nerve cells) in the brain stop working, lose connections with other brain cells, and die. Alzheimer's disease (AD) is the most common cause of dementia in older adults. This book provides a general overview of the different types of dementia, describes how these disorders are diagnosed and treated, offers tips for caregivers, and covers other relevant topics.
