Clock Drawing Test (CDT)

Health & Fitness

Free · Designed for iPad

The Clock Drawing Test is a simple tool used to screen for signs of early dementia, including Alzheimer’s disease. The Clock Drawing Test is often used in combination with other screening tests but can be valuable on its own. The early detection of dementia is important since medications exist which can help slow the progression of Alzheimer's disease. The Clock Drawing Test can provide a strong indication of early dementia but cannot diagnose dementia or the type of dementia. In addition to using this app, before making any medical decisions seek a doctor’s advice.
