@entity1 @entity308 @entity161 @entity716 @entity1767 @entity1154
Language comprehension, measured by the Luria-Nebraska Relational Concepts Factor Scale, was evaluated twice in 15 male DSM-III-R @entity161 @entity1 during a controlled double-blind @entity1767 maintenance (without anticholinergics) and placebo replacement protocol. Fifteen male normal controls were tested once. @entity1 and controls were matched on age and education. Language comprehension was significantly reduced in @entity1 under both pharmacologic conditions, as compared with controls. @entity1 ' comprehension accuracy did not differ significantly between neuroleptic-treatment and placebo replacement conditions. @entity1 ' comprehension accuracy was independent of positive symptoms, @entity308 , measures of clinical course, and CSF and plasma @entity1154 . Comprehension accuracy was also not associated with @entity1 ' educational level or WAIS-R measures of their intellectual and short-term memory functioning. @entity1 ' comprehension performance was significantly associated only with the negative symptom anhedonia-asociality during @entity1767 maintenance. Thus, language comprehension in @entity161 @entity1 was independent of changes in pharmacologic treatment and the positive symptoms of @entity716 . Results suggest language comprehension may represent a stable or trait characteristic in @entity161 .
