Dementia is a term used to refer to a progressive decline in cognitive functions. It is characterized by a non –specific set of symptoms.

Although dementia can affect any adult it is primarily a disease of old age. 5% of the world’s elderly suffer from dementia. In these individuals it comes about as a result of neurodegeneration that ushers in changes in the brain. There is an impairment in social behavior and emotional control and the affected individual is often prevented from doing things that they could earlier do.
The personality of an individual suffering from dementia undergoes a prominent change. Memory loss is strongly linked to dementia. Diseases such as Alzheimer’s disease and stroke can bring about dementia. Dementia is often not treatable but its onset can be slowed, and its symptoms controlled, with the help of medications.
