Abstract: The present disclosure is directed to methods of restoring glial cell K+ uptake in a subject. This method involves selecting a subject having impaired glial cell K+ uptake, and administering, to the selected subject, a RE1-Silencing Transcription factor (REST) inhibitor under conditions effective to restore glial cell K+ uptake. Subjects having impaired glial cell K+ uptake include those at risk of having or having a neuropsychiatric disease or disorder.
