I have just learned that 1 in 10 people over 60 have dementia, new Singapore study claims. Dementia is the medical term used to describe a group of symptoms consisting of memory loss, impaired judgement, disorientation and behavioural changes, which are of sufficient severity to cause loss of function.
It is good to keep your parents or grandparents with dementia safe with safety tags (engraved with emergency phone numbers). It provides information for kind and helpful people in case you loved ones wanders around.
