Alzheimer's & Dementia

Alzheimer’s disease is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills. Alzheimer’s is the most common cause of dementia among older adults. Dementia is the loss of cognitive functioning—thinking, remembering, and reasoning—and behavioral abilities to such an extent that it interferes with a person’s daily life and activities.

Alzheimer’s Disease | Definition, Causes, Diagnosis & Treatment

Alzheimer’s Disease (AD) is the most common form of dementia worldwide (60-70% of all dementia cases) and is a progressive neurodegenerative disorder.

Late-life mood disorders may signal neurodegenerative diseases

Depression and bipolar disorder of late onset may represent more than just mental health conditions. Growing evidence suggests these late-life mood disorders (LLMDs) could be not merely risk factors, but rather early warning signs of neurodegenerative diseases like dementia, even when they appear years before memory loss or other cognitive symptoms become apparent.
