Progressive supranuclear palsy (PSP) with abnormal postures. This 56‐year‐old Gujarati female had PSP‐P with features not commonly associated with the disease, including evidence of rapid eye movement (REM)‐sleep behavior disorder and significant abnormal postures. She had presented with slowing more on the left, but developed worsening postures and gait imbalance 3 years later. The videos taken 3–4 years after onset show classic eye signs of PSP (vertical saccadic slowing, round‐the‐house sign, square‐wave jerks, eyelid opening apraxia), a positive applause sign, asymmetric upper limb bradykinesia (left>right), impaired postural reflexes. The unusual feature demonstrated here is marked anterocollis and lateral trunk flexion.
