Dementia: Understanding Cognitive Decline and Its Causes

Dementia is a general term for a decline in mental ability severe enough to interfere with daily life. Alzheimer's disease is the most common type. Dementia is not a normal part of aging.

It involves impairment in memory, thinking, reasoning, language, and/or behavior. Other types include vascular dementia, Lewy body dementia, frontotemporal dementia, and mixed dementia. Early diagnosis allows for better management and planning.
