Alzheimer’s disease is the most common cause of dementia. Dementia is a collective name for conditions in which progressive degeneration of the brain affects memory, thinking, behaviour and emotion. Symptoms may include:
- loss of memory
- difficulty in finding the right words or understanding what people are saying
- difficulty in performing previously routine tasks
- personality and mood changes
Dementia is not an illness or a disease in itself, but it is a broad term used to describe a range of signs and symptoms that occur when the brain is affected by certain diseases or conditions. The Alzheimer’s Society defines dementia as: ‘’Evidence of a decline in memory and thinking which is of a degree sufficient to impair functioning in daily living, present for six months or more’’ .
