Abstract
‘Procerus sign’ has been described as vertical wrinkles in the glabella region and
bridge of the nose of patients with Progressive Supranuclear Palsy. The action of
Corrugator and Orbicularis Oculi produce the vertical wrinkling. The relevance of
this sign in early clinical diagnosis has been established and this sign has gained
importance in literature and has been quoted as a useful sign in texts following the
original description. We prospectively performed a cross sectional analysis of the
facial appearance in subsequent Parkinsonism patients and found statistically significant
presence of this sign in PSP compared to other Parkinsonian disorders. We recommend
that this should be called “vertical wrinkling of the forehead” to avoid confusion
and emphasize the dystonic nature of this condition rather than contraction of a single
muscle as indicated by ‘Procerus sign’.
