Effects of tES Combined With Retrieval Practice on Semantic Memory in Patients With Schizophrenia
Effects of Transcranial Electrical Stimulation Combined With Retrieval Practice on Semantic Memory in Patients With Schizophrenia
Source: ClinicalTrials.gov · Last updated 15 Nov 2024
Brief summary (registry, in English)
The semantic processing deficit stands as a central feature of cognitive abnormalities in schizophrenia. Both transcranial electrical stimulation (tES) and retrieval practice have been demonstrated as external techniques capable of ameliorating the semantic processing deficit in individuals with schizophrenia. The inquiry examines whether the combined effect of tES and retrieval practice, following tES intervention targeting the left dorsolateral prefrontal cortex (L-DLPFC) in patients with schizophrenia, contributes to the preservation of semantic memory in these individuals. Investigators plan to recruit 60 patients diagnosed with schizophrenia from hospitals. Treatment is administered by two examiners, each patient receives transcranial electrical stimulation（2mA×20min） with simultaneous learning of word lists. Each participant of each stimulation type was involved in both learning conditions, meaning that all participants completed both retrieval and restudy learning and testing Subsequently, Investigators observed their immediate and delayed memory performance through tests.
