Myerson's sign is a medical condition where a patient is unable to resist blinking when tapped on the glabella, the area above the nose and between the eyebrows. It is often referred to as the glabellar reflex. It is often an early symptom of Parkinson's disease, but can also be seen in early dementia as well as other progressive neurologic illness. It is named for Abraham Myerson, an American Neurologist.
