title: Associations between components of metabolic syndrome and cognition in patients with schizophrenia.
abstract: The metabolic syndrome and cognitive dysfunctions are common in patients with schizophrenia, yet there is no general consensus concerning the effects of the components of the metabolic syndrome on various cognitive domains. The goal of this study was to investigate the relationship between components of the metabolic syndrome and cognition in patients with schizophrenia. Components of the metabolic syndrome and neurocognitive functioning were assessed in 68 patients with schizophrenia. The Brief Assessment of Cognition in Schizophrenia (BACS) was used to assess neurocognition. Hyperglycemia and hypertension were the only components of the metabolic syndrome found to be associated with cognitive functioning. Patients with schizophrenia who were hypertensive showed cognitive impairments in 2 domains, with a negative association found between hypertension and verbal memory (P=0.047) and verbal fluency (P=0.007). Hyperglycemia was associated with higher scores on verbal memory (P=0.01) and verbal fluency (P<0.001). It appears that medical treatment of certain components of the metabolic syndrome could affect cognitive performance in patients with schizophrenia.
