'''Myerson's sign''' or '''glabellar tap sign''' is a clinical [[physical examination]] finding in which a patient is unable to resist [[blinking]] when tapped repetitively 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.<ref>{{cite journal|last1=Conley|first1=Scott|last2=Kirchner|first2=Jeffrey|title=''Parkinson's disease--the shaking palsy'' Underlying factors, diagnostic considerations, and clinical course|journal=Postgraduate Medicine|date=15 July 1999|volume=106|issue=1|doi=10.3810/pgm.1999.07.604|pmid=10418573}}</ref><ref>{{cite journal|last1=Sunohara|first1=N|last2=Tomi|first2=H|last3=Satoyoshi|first3=E|last4=Tachibana|first4=S|title=Glabella tap sign.
