What's Dementia

Answer 1

Dementia is the progressive decline in cognitive function due to damage or disease in the brain beyond what might be expected from normal aging. Particularly affected areas may be memory, attention, language, and problem solving. In the later stages of the condition affected persons may be disoriented to time, place and person.

The many different causes of dementia can be classified as either reversible or irreversible. Less than 10% of cases of dementia are considered reversible, and even in these cases it usually is not fully reversed.
