Dementia is caused by a variety of brain illnesses that affect memory, thinking, behavior, and ability to perform everyday activities. This guidebook provides essential information on Dementia, but also serves as a historical survey, by providing information on the controversies surrounding its causes, and first-person narratives by people coping with Dementia. Readers will learn from the words of patients, family members, or caregivers. The symptoms, causes, treatments, and potential cures are explained in detail. Alternative treatments are also covered. Each essay is carefully edited and presented with an introduction, so that they are accessible for student researchers and readers.
