What is Alzheimer’s disease?
There are many types and causes of dementia, but Alzheimer’s disease is the most common form, accounting for between 60 and 70 per cent of all cases.
Common early symptoms of Alzheimer’s include short-term memory loss, apathy and depressed mood, but these symptoms are often just seen as being a part of normal ageing, making early diagnosis difficult.
Doctors diagnose Alzheimer’s on the basis of medical examination, patient history and cognitive tests, and can use imaging to rule out other forms of dementia. However, a definitive diagnosis of Alzheimer’s is only possible after death, when examination of brain tissue can reveal whether a person had the deposits of amyloid and tau proteins that are characteristic of the condition.
