Dementia is not a specific disease; rather, it is a group of conditions characterised by the gradual impairment of brain function. It commonly affects people’s ability to think, remember and reason, as well as affecting their personality and impairing other core brain functions such as language and movement. The condition is degenerative and irreversible.
