There are many types of dementia, with Alzheimer's Disease (AD) being the most common, accounting for 60-80% of all cases of dementia. Although the biggest risk factor is increasing age, Alzheimer's and other dementias are not a normal process of aging. AD in particular can be difficult to clearly diagnose, and while researchers are discovering more ways like brain imaging and genetic testing to assist with diagnosis, there is still no single test. To date, there is also no cure for AD, but current treatments can lessen the symptoms and improve quality of life.
