Results are similar after treatment with neuroleptics, although the cognitive deficit may be slightly milder. Bilder et al10 administered a comprehensive neuropsychological test battery to 94 first-episode patients after initial stabilization of psychosis. Patients were impaired on all 41 measures, with the majority of deficits exceeding one standard deviation. Inhibitors,research,lifescience,medical Prospective longitudinal studies of schizophrenia patients following the first episode have suggested stabilization and even mild improvement over time. Censits et al11 followed 30

first-episode patients for 19 months. Patients remained one to two standard deviations below controls on all neuropsychological measures, with no significant change in performance over time. In another follow-up study 35 first-episode or recent-onset schizophrenia patients were Inhibitors,research,lifescience,medical administered a comprehensive battery of neuropsychological tests during index hospitalization and at either 1- or 2-year follow-up examination.12 Neuropsychological deficits remained stable in most domains. Studies with longer duration of follow-up show similar Inhibitors,research,lifescience,medical results. Gold et al13 studied 54 first-episode or recent-onset schizophrenia patients and followed them for 5 years. They found a modest, 3-point improvement in IQ, especially in performance

IQ. More specifically 37 subjects improved their performance, 13 subjects performed worse, and 4 subjects showed no change. Change was also evident on specific Inhibitors,research,lifescience,medical neuropsychological measures: attention, memory, and executive functions slightly improved, and motor speed deteriorated. DeLisi et al14 evaluated the longitudinal neuropsychological

performance of 20 first-episode patients at index hospitalization Inhibitors,research,lifescience,medical and at 4-year follow-up. The majority of the neuropsychological test scores did not change over time; improvement occurred in tests of concentration and speed, and overall global functioning. Hoff et al15 studied language, executive, memory processing speed, and sensory-perceptual functions in 42 patients with a first hospitalization for schizophrenia or schizophreniform disorder at approximate yearly intervals for the first 2 Chlormezanone to 5 years of illness. Patients consistently scored one to two standard deviations below normal comparison subjects on neuropsychological test measures during the 5-year course of the study Patients exhibited some improvement on measures of language, executive functions, and a mild decline in verbal memory. In their meta-analysis of neuropsychological performance in schizophrenia, Heinrichs and Zakzanis6 found no significant relationships between IQ deficits and potential moderators, including symptom NLG919 research buy severity, age, education, neuroleptic dose, sample gender composition, or age of illness onset.
