what is dementia why it happens
Dementia describes a collection of symptoms that are caused by disorders affecting the brain. It is not one specific disease. Dementia affects thinking, behaviour and the ability to perform every day tasks. Brain function is affected enough to interfere with the personâs normal social or working life.
Dementia is marked by a gradual impoverishment of thought and other mental activities that eventually affect almost every aspect of life. The most common symptoms of dementia are: Frequent and progressive memory loss. People with dementia begin to forget more and more, and the most recent events seem to be forgotten most quickly. Occasionally though, clear pockets of memory are still present, and these are usually triggered by familiar faces, smells, touches, songs, or rituals.
