Schizophrenia Clinical Trial
Official title:
Enhancing Prefrontal Oscillatory Activity and Working Memory Performance With Noninvasive Brain Stimulation in Early-course Schizophrenia
This study will investigate the effects of intermittent Theta Burst Stimulation (iTBS) on natural oscillatory frequency of the dorsolateral prefrontal cortex (DLPFC) and working memory in early-course schizophrenia (EC-SCZ). Transcranial magnetic stimulation (TMS) will be used to evoke oscillatory activity, and EEG will record the responses of EC-SCZ participants. A working memory task will also be incorporated in order to determine how DLPFC natural frequency (NF) is related to working memory performance. iTBS (active or sham) will be administered, then the oscillatory activity of DLPFC and working memory performance will be reassessed. The overarching goal is to determine whether iTBS can acutely enhance the oscillatory activity of the DLPFC and to evaluate the relationship between changes in the DLPFC and working memory performance.
The overarching goal of this proposal is to establish whether, by acutely enhancing dorsolateral prefrontal cortex (DLPFC) oscillatory deficits experimentally, there is a corresponding improvement in working memory (WM) function in early-course schizophrenia (EC-SCZ) patients. To achieve this goal, the investigators will perform TMS/EEG assessments of DLPFC and related oscillatory parameters and evaluate WM ability with the AX-Continuous Performance Task (AX-CPT) before and after two theta burst stimulation (TBS) sessions (intermittent (iTBS) and sham TBS of DLPFC) in 75 EC-SCZ patients. Aim 1. Establish the acute effects of active vs. sham TBS on DLPFC oscillatory activity/NF of EC-SCZ patients. The investigators will iTBS to enhance DLPFC oscillatory activity/NF, as assessed with TMS/EEG, in EC-SCZ patients. H1: TBS condition (active vs sham) will moderate the change in DLPFC oscillatory activity/NF from pre to post-TBS, such that DLPFC oscillatory activity/NF will increase following iTBS (but not sham). Aim 2. Assess the impact of acute active vs. sham TBS on WM performance in EC-SCZ patients. The investigators will assess the acute impact of active vs. sham iTBS on WM performance in EC-SCZ patients. H2: iTBS condition (active vs sham) will moderate the change in WM from pre- to post-TBS, such that AX-CPT performance will improve following iTBS (but not sham). Aim 3. Examine the relationship between TBS-related changes in DLPFC oscillatory activity/NF and WM performance in EC-SCZ patients. H3: iTBS-induced increase in DLPFC oscillatory activity/NF will predict better post-iTBS WM performance in EC-SCZ patients. ;
