Unilateral Amnesic Stroke:Six New Cases and a Review of the Literature
Stroke 24:1033-1042, Ott,B.R.&Saver,J.L., 1993
See this aricle in Pubmed

Article Abstract
Six patients developed acute amnesia associated with unilateral stroke. Brain computed tomography or magnetic resonance imaging revealed lesions in limbic structures,which accounted for the memory deficit.Based on these as well as similar cases in the literature,we delineate three distinct syndromes of unilateral amnesic stroke involving the territories of the posterior cerebral,anterior choroidal,and thalamic penetrating arteries. Eighty-five percent of reported cases have involved the left hemisphere. Persistent as well as transient amnesia may be the sole or primary manifestation of unilateral hemispheric stroke.The vascular mechanisms of amnesic stroke are diverse.Patients presenting with acute amnesia possibly related to cerebral ischemia should be classified by documented or presumed lesion site as well as the involved vascular territory.Left amygdalohippocampal or diencephalic dysfunction may produce a particular vulnerability to global amnesia.
