About 5 to 15 percent of people 65 and older suffer from some form of dementia - the most common of which is Alzheimer's disease. As people age, the risk of dementia increases. Moderate to severe dementia is found in three percent of those aged 65 to 74 and in 30 percent of those 85 and older.

Dementia accounts for a growing share of health care expenses and medical resources. Decline in thinking abilities often requires increased supervision and support systems - usually at a great expense.

Detecting signs of dementia at an earlier stage and starting appropriate treatments immediately appears to reduce the rate of mental decline, increase independence in day-to-day activities, reduce health care costs, and improve quality of life.
