<p><b>OBJECTIVE</b>To analyze clinical features of
patients with
Gerstmann syndrome (GS).</p><p><b>
METHODS</b>We retrospectively analysed the clinical manifestations of 7
patients (6
men and 1
woman) with GS
secondary to cerebral
vascular diseases and reviewed the
literatures.</p><p><b>RESULTS</b>The age ranged from 51 to 70 years with a mean of 70 years. They all had sudden onset and the tetrad of GS-
finger agnosia, left-right
disorientation,
agraphia and
acalculia, 3
patients accompanied by incomplete
aphasia, 3 by
anomic aphasia, 2 by
alexia and 1 by constructional
apraxia. Cranial computed tomographic scan showed low-density focus of the left
parietal lobe in 6 cases and high-density focus of the left
parietal lobe in 1 case.</p><p><b>CONCLUSION</b>GS has the high value in
localization and the lesion is mainly localized to
angular gyrus of the dominant hemisphere.</p>
