Objective: Gerstmann in 1924. observed in a few patients a concomitant impairment in discriminating their own fingers, writing by hand, distinguishing left from right and performing calculations. He claimed that this tetrad of symptoms constituted a syndromal entity, assigned it to a lesion of the dominant parietal lobe. Since than, Gerstmann`s syndrome (GS) was enigma for neuropsychologists. The aim of this study was to analyze frequency and clinical features of GS among acute stroke patients. Patients and methods: We prospectively analyzed 194 acute stroke patients (average age 65±11.06 years, male 113 (58.2%), female 81 (41.8%) hospitalized at Department of Neurology, University Clinical Center Tuzla, during the six mounths in 2010. For clinical assessment of agraphia, alexia and acalculia we used Minessota Test for Differential Diagnosis of Aphasias. Results: Among these acute stroke patients, 59 (30.40%) had alexia, agraphia and acalculia or different combinations of these disorders. Two patients (3.4%) had agraphia and acalculia associated with other part of tetrad of GS: finger agnosia and left-right disorientation. They both where men, right handed, and cranial computed tomography scan showed ischemic lesion in the left parietal and left temporoparietal lobe. Conclusion: Gerstmann`s syndrome is rare clinical entity, and has the high value in localization and the lesion is mainly localized to angular gyrus of the dominant hemisphere.
Key words: Gerstmann`s syndrome, acute stroke.
