Transient memory impairment can be occurred by many causes. One of them is acute focal brain lesion in strategic site. Caudate nucleus and medial basal ganglia (globus pallidus) are lesion of strategic site. They play its role in cognitive processing. But lateral basal ganglia (putamen) is known as a structure involving movement, not cognitive function. We report a interesting case of transient memory dysfunction with acute focal putamen ICH with old caudate nucleus infarction.

Keywords: Vascular cognitive impairment; Putamen; Intracranial hemorrhage
