Lacunar syndromes were categorized as pure motor hemiparesis(PMH),pure sensory syndrome(PSS),sensorimotor syndrome(SMS),ataxic-hemiparesis(A-H), and other lacunar syndromes.Brain imaging findings were classified as radiologic lacune or nonlacune.While lacunar syndromes,especially PSS and A-H,are highly predictive of lacune,in about one in four patients presenting with lacunar syndromes confirmed radiologically the condition is associated with nonlacunar mechanisms of infarction.Noninvasive neurovascular and cardiac evaluations are still warranted even among patients with lacunes. |
