Abstract:

Abstract Objective To examine psychometric performance in a sample of patients with postpolio syndrome ( PPS ) with subjective cognitive complaints . Patients and methods The sample consisted of 37 PPS patients ( 17 men ) referred to our outpatient neuropsychological service . The mean age at the neuropsychological assessment was 55 years ( SD : 4 .58 years ) . A total of 59 .5% was receiving pharmacological treatment for anxiety - depression . The results obtained by patients in the neuropsychological assessment were compared with normative data to identify the percentage of patients with pathological scores on the tests applied . Results Patients with PPS had pathological scores on all the neuropsychological tests . A particularly significant finding was the percentage of patients with scores indicative of cognitive impairment in tests that assessed cognitive processing speed , verbal learning , phonemic verbal fluency and cognitive flexibility . No statistically significant differences were observed in patients’ performance depending on the presence or absence of anxiety or depression . Conclusions Patients with PPS and subjective cognitive complaints performed less well on neuropsychological assessment than the general population .
