1. A method for differentiating cognitively normal elderly individuals from mildly demented patients with Alzheimer'"'"'s disease comprisingplacing head tilt monitoring means on the individual and facing the individual towards a video monitor;
- positioning on said video monitor a target frame and cursor, said cursor position controlled by the head tilt of the individual;
monitoring head tilt by the individual by detecting signals from said head tilt monitoring means said signals being indicative of said cursor position;
converting signals obtained during said monitoring step into measures of ability to maintain said cursor within said target frame.

Abstract
A method for differentiating cognitively normal elderly individuals from mildly demented patients with Alzheimer'"'"'s disease by monitoring motor/psychomotor test results by the use of various computer monitored transducer apparatus attached to the individual while the individual undergoes testing. Head tracking ability, head steadiness, EMG-Arm extension tracking, and joint position matching are measured parameters used in the method.
