📖What is Dementia?
Dementia is a general term for a decline in cognitive function severe enough to interfere with daily life, encompassing a range of underlying conditions including Alzheimer's disease, vascular dementia, and Lewy body dementia. It involves progressive impairment of memory, thinking, language, judgment, and behavior, gradually eroding a person's ability to live independently. The condition results from damage to brain cells that affects communication between neurons, and its progression and specific symptoms vary depending on the underlying cause. Dementia primarily affects older adults, though it is not considered a normal part of aging.
