The Alzheimer’s Disease

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’’ .
