Stroke may be associated with different types of movement disorders, such as
hyperkinetic syndromes (hemichorea-hemiballism, unilateral asterixis,
limb-shaking, dystonia, tremor, myoclonus) and hypokinetic syndromes (especially
vascular parkinsonism). However, movement disorders are rare and transient in
acute stroke and, as a permanent consequence, are more often delayed. While
ischemic and hemorrhagic strokes can happen at any level of the
frontal-subcortical motor system, they can be explained most of the time by a
dysfunction in the basal ganglia motor circuit. However, only brain MRI allows
the involved structure(s) to be precisely located, and each syndrome is specific
to the type of lesion. Treatment is above all symptomatic.
Only limb-shaking
syndrome requires urgent surgical treatment because of the low-perfusion
hemodynamic state. The functional prognosis depends on the type of movement
disorder.
