Аннотация: Introduction: Studies have shown that verbal abstract reasoning(VAR) is deteriorated in midle-age onset schizophrenia (AOS). However, studies included late-onset schizophrenia (LOS) are limited.Objectives: We examined VAR in LOS patients compared tohealthy controls.Methods: There were two groups: 14 LOS patients (mean age 609,13 females) and 11 healthy controls (mean age 58.410, 7 females).WAIS Similarities Subtest and proverb interpretation test were usedto examine VAR. Proverb interpretation test included 9 proverbs inRussian. The scoring included 1 to 7 points scale, where 1 pointmatched correct interpretation and 7 points matched the absence ofinterpretation. To determine differences between groups TheMann-Whitney U test was applied.Results: No significant differences were found between LOSand controls on Similarities Subtest (U=48, p=.12) and proverbinterpretation test (U=41.5, p=.06). Mean scores on proverb interpretation were 2412 for LOS and 16.36 for controls. Mean scoreson Similarities Subtest were 173.2 and 192.5 for LOS and controlsrespectively. Noteworthy, bizarre answers, typical for AOS patients’performance on VAR tests, were very rare in the LOS group.Conclusions: Despite the absence of significant differences, theLOS group performed slightly worse than controls. Domains ofVAR are differently impaired in LOS. Possibly, proverb interpretation is a more complex task than Similarities Subtest and requireshigher level of executive functions, verbal memory and other mentalcapacities to complete it. Further studies with a bigger sample sizeand including AOS group, are required.Conflict of interest: NoKeywords: Verbal Abstract Reasoning; Late-onset schizophrenia
