Transcranial Weak Current Stimulation Treatments for Working Memory Dysfunction in Schizophrenia
In Brief
A clinical study evaluating transcranial direct current stimulation (tDCS) for Schizophrenia and Schizo Affective Disorder. Completed, enrolled 33 participants across 1 site.
Detailed Summary
For the present study, Investigators will examine the efficacy of active prefrontal anodal tDCS versus placebo (sham) interventions to treat WM dysfunction in schizophrenia. Investigators selected the prefrontal stimulation modality that proved most effective in enhancing high-load WM performance in single dose stimulation in healthy participants . The study employs a multi-stimulation approach, with 2 sessions per day for 5 consecutive days in the active treatment group (n=15) compared to a group that receives only sham stimulation (n=15). This preliminary approach is based upon findings of a recent study applying cathodal tDCS stimulation over left temporoparietal cortex (with left prefrontal anodal stimulation) for the treatment of persistent auditory hallucinations in schizophrenia. In a a recent study clinical benefits were maintained for at least 3 months following stimulation. In the present study, in addition to clinical outcome, researchers will evaluate whether similar improvement can be obtained with WM, EEG activity, and functional outcome (e.g., discharged from hospitalization following significant improvement or remission).
Study Details
Timeline
Interventions
10 sessions of Anodal tDCS of the dorsolateral prefrontal cortex over a period of 5 consecutive days (two session a day). Each session includes the placement of two tDCS electrodes (anodal at left prefrontal area and cathodal above the vertex) and 20 mins of anodal prefrontal stimulation. The tDCS session is received two time a day with a 3-5 hours interveal betwen sessions.
