Abstrakt

Cerebral stroke is the very common cause of executive dysfunctions,
such as disinhibition and inability to switch of attention. The aim of this longitudinal
study was to determine a clinical characteristic of executive dysfunctions in
light of the neuropsychological examinations. Forty-four patients who had ischemic
stroke were examined twice with a twelve-month interval. At each session executive
functions were measured on the same patients. Executive functioning was
measured by three popular tasks, i.e. an experimental version of the Stroop Color-
Word Interference Test, Verbal Fluency Test, and Trail Making Test. Twenty-five
healthy volunteers were examined once only to transform patients’ results of neuropsychological
testing into standardized form. Executive impairment was found
in 24 patients (i.e. 65% of the clinical group), who failed to complete at least one of
the three tests. Patients manifested executive dysfunctions which were highly heterogeneous
with respect to character, severity and their prevalence. Overall, there
was clear evidence that executive functions showed substantial recovery. Timecourse
of distinct executive dysfunctions was similar.
