Abstract: 9 cases with left thalamic hemorrhage (LTH), 9 cases with right thalamic hemorrhage (RTH), and 18 cases without cerebral organic lesion (control), as was demonstrated by CT scan, were examined by using a clinical memory scale, and through clinical aphasic examinations and sp- atial functional examinations. None of the cases had aphasia and distur- bance of spatial function. But the result. by the memory scale demonst- rated that all subtest scores and MQ in LTH sroup were sisnificantly lo- wer than those of the controls This suggesfs that left thalamic damage may cause long-term amnesia.
