Study on prospective memory in schizophrenia patients with concomitant metabolism syndrome

Abstract

Objective To investigate the event-based prospective memory(EBPM)and time-based prospective memory(TBPM)in schizophrenia patients with concomitant metabolism syndrome, and to provide theory basis for early intervention and treatment. Methods According to inclusion standard, 50 schizophrenia patients with concomitant metabolism syndrome and 50 schizophrenia patients without metabolism syndrome matched in age, gender and education were assessed with a neuropsychological battery of tests including EBPM and TBPM tasks. Results In the EBPM task, there was significant difference between schizophrenia patients with and without metabolism syndrome (3.46±0.91 vs 3.86±0.81, t=-2.326, P=0.022). A statistically significant difference in TBPM was observed between schizophrenia patients with and without metabolism syndrome (3.02±1.12 vs 3.78±0.89, t=-3.770, P=0.000). Conclusion The schizophrenia patients with metabolism syndrome have severer prospective memory impairment than those without metabolism syndrome.
