1. Glabella reflex

4. The glabella : the area immediately above the nose on the forehead.
In most people, when this area is tapped repetitively at one second intervals, the blink response extinguishes after a short number of taps.

5. In patients with frontal lobe injury and particularly with Parkinson’s disease, the response does not extinguish for more than 3-7 repetitions.
This number is not carved in stone in the literature but in “normal” people it usually disappears within a few beats.

6. A negative glabellar tap reduces the likelihood that a patient has Parkinson’s disease.
It is important to approach the patient from behind with your tapping hand so it is not over their face during the tapping movement.
