Dysfunction of a distributed neural circuitry in schizophrenia patients during a working-memory performance.
BACKGROUND In a recent longitudinal study of first-episode schizophrenia patients, we found that while dysfunction of the right dorsolateral prefrontal cortex (DLPFC), right thalamus, left cerebellum and cingulate gyrus normalized with antipsychotic treatment and significant reduction in symptomatology, the left DLPFC, left thalamus, and right cerebellum remained disturbed. In the present study...

متن کاملPrefrontal cortex dysfunction during working memory performance in schizophrenia: reconciling discrepant findings.
Working memory (WM) deficits are a persistent, disabling and relatively treatment-resistant feature of schizophrenia that may underlie many cognitive deficits and symptoms. They are associated with prefrontal cortex dysfunction. While most neuroimaging studies of WM demonstrate "task-related hypofrontality" in schizophrenic relative to healthy subjects, several recent studies have reported equa...
متن کاملEmotional Working Memory in Alzheimer's Disease Patients
BACKGROUND Few studies have assessed whether emotional content affects processes supporting working memory in Alzheimer disease (AD) patients. METHODS We assessed 22 AD patients and 40 elderly controls (EC) with a delayed matching and non-matching to sample task (DMST/DNMST), and a spatial-delayed recognition span task (SRST; unique/varied) using emotional stimuli. RESULTS AD patients showe...
