I just read about an Academy in Russia that has built a hypthesis in recognizing some of the earliest stages of Parkinson’s. The following is the process of their experimentation:
To find reliable methods of early diagnostics, the Moscow neurologists examined 12 healthy probationers and 16 patients suffering from the first and the second stages of Parkinson’s disease. The participants to the experiment were tested with the help of the hardware and software complex, which analyzes the moving activity. The probationers were (by moving the eyes only) to fix the look on the target, which was shifting across at the angle of 40 degrees. They were suggested to make sliding movements by the head to the left and to the right along the horizontal plane, retaining the look on the target, which moved synchronously with the head movements. And, finally, after several open-eye training sessions, the participants transferred the cursor onto the target by memory, their eyes being curtained off. These three tests allow to check how the patients move separate parts of the body (only eyes, head or hand). In the course of the fourth test, the probationers shifted the cursor from one target to another by moving the eyes, head and hand, i.e. by coordinating their movements.
