Parkinsonism and multiple sclerosis, what is behind?
The awareness of the coexistence of both diseases in some patients resulted in an ongoing debate on either causal or coincidental relationship between multiple sclerosis (MS) and parkinsonism [1, 2]. Present data offers some rationale for both theories. In the cases presented in the literature, mostly, Parkinson’s disease (PD) follows the MS [1, 2].
A 43-year-old man complained of tremor of the left arm in 2010. Neurological examination revealed resting tremor of the left upper extremity with mild bradykinesia and mild rigidity, and hypomimia. He had a normal-based gait, with absent left arm swing. The symptoms markedly improved by administration of pramipexole.
