18 CIS patients and 18 controlswere subjected to the Wechsler memory scale, Rey Auditory Verbal Learning, Rey Complex Figure, Paced Auditory SerialAddition, Digit Span, verbal fluency, Stroop color card test, D2, and Digit Symbol tests.Results:
CIS patients had significantlyworse performance on the Paced Auditory Serial Addition Test (PASAT) 2 seconds (P=0.009) and on verbal fluency tests(P=0.0038) than controls.Conclusion:
