Frontotemporal disorders are rare brain diseases that strike middle-aged adults, causing devastating changes in behavior, personality, emotions, language, and movement. The National Institute on Aging offers a booklet that sheds light on these little-known disorders. “Frontotemporal Disorders: Information for Patients, Families, and Caregivers,” describes the major types of frontotemporal disorders—behavioral variant frontotemporal dementia, primary progressive aphasia, corticobasal syndrome, and progressive supranuclear palsy. It discusses what is known about their causes, diagnosis, and common symptoms. Short vignettes help illustrate what it’s like to live with the disorders.
