Dementia is the umbrella term used to describe the symptoms of a large group of illnesses which cause a progressive decline in a person’s mental functioning.

It is a broad term which describes a loss of memory, intellect, rationality, social skills, inability to do everyday things, difficulty in communication, confusion,  frustration, as well as personality and behaviour changes.  The symptoms generally get progressively more severe with time. There are over 200 different types of dementia, each with a slightly different set of symptoms.
