Temporal Memory in Schizophrenic Patients

Temporal order memory deficits are a central feature of cognitive abnormalities in schizophrenia. The dorsolateral prefrontal cortex contributes to the extraction of temporal contextual information. Transcranial direct current stimulation (tDCS) and interim testing have been shown to be external techniques that can improve temporal order memory deficits in schizophrenia patients. Transcranial alternating current stimulation (tACS) can also improve cognitive functioning in patients with schizophrenia. This study intends to investigate the learning effects of temporal order memory under two learning strategies during tDCS targeting the left dorsolateral prefrontal cortex (L-DLPFC) and transcranial direct current stimulation (tDCS) interventions in patients with schizophrenia, to investigate whether it can promote the retention of temporal order memory in patients, and to compare the differences in the effects of the two intervention modalities. This study was planned to recruit 75 patients diagnosed with schizophrenia from the hospital. A single online tDCS (2 mA × 20 min) and tACS (1.5 mA × 20 min, theta rhythm) intervention was conducted during which participants performed a temporal-sequence memory task for visual pictures, and test scores were compared for each stimulus type on an intermediate test and repetition of the two strategies of learning.
