Many Alzheimer patients are unable to tell the correct time.
If you ask them to draw a clock in the noon position,with minute and hour hands, they may have the hands at 10 or 2 o clock. There is a special test called the Clox Test that researchers are finding to be more accurate at diagnosing Alzheimer dementia than the standard cognitive test used since 1976, the Mini Mental State Exam. Whether the inability to tell time from a clock is due to poor vision or to changes in the brain itself is not yet known. But either way, an inability to tell time is a problem. The talking clock shown here will voice the correct hour and minute when programmed and it will also voice when the alarm is programmed.
