General Medicine · Neurology: Parkinson-plus syndromes
Sample itemA man with parkinsonism poorly responsive to levodopa has severe orthostatic hypotension, urinary retention and cerebellar signs. Which is the likely diagnosis?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
C. Multiple system atrophy
Multiple system atrophy combines parkinsonism or cerebellar signs with early prominent autonomic failure, and alpha-synuclein accumulates in oligodendroglia. Progressive supranuclear palsy shows vertical gaze palsy, falls and a tau pathology. Levodopa response is poor in both.
Option by option
A. Wilson disease
Wilson disease occurs in the young with liver disease.
B. Idiopathic Parkinson disease
Idiopathic PD responds well to levodopa and autonomic failure comes later.
C. Multiple system atrophy (correct)
Correct. Early autonomic failure with cerebellar signs points to MSA.
D. Progressive supranuclear palsy
PSP presents with vertical gaze palsy and early falls.
