The Alzheimer's disease is most common cause of Dementia with around 500,000 sufferers in the UK. The disease accounts for 50 to 70% of all dementia, affecting an estimated 1 in 14 people over the age of 65 and 1 in every 6 people over the age of 80.
Between five and 20 percent of people aged over 65 have mild cognitive impairment.
