Dementia

Dementia is not a specific disease. It is a descriptive term for a collection of symptoms that can be caused by a number of disorders that affect the brain. People with dementia have significantly impaired intellectual functioning that interferes with normal activities and relationships.

What Causes Dementia?

Dementia occurs due to loss of brain function that occurs with certain diseases. It can affect several brain functions such as memory, thinking, language, planning, behavior and judgement. Dementias are usually progressive and worsen with time. They usually are degenerative and non reversible.
