Dementia is a term used to describe a group of similar conditions characterised by gradual impairment of brain function. Dementia may affect a person’s memory, speech, cognition (thought), behaviour, mobility and personality, and their health and functional ability decline as the disease progresses. Risk factors include age, genetics, family history, tobacco smoking, physical inactivity, obesity, diabetes and high blood pressure. The burden of disease from dementia is greater for females than males, and is higher among people aged 65 and over.
