摘要：
Transcranial alternating current stimulation (tACS), a noninvasive brain stimulation technique that uses low-intensity alternating current, has been postulated to be a potential therapeutic option in treating the cognitive deficits in schizophrenia. Transcranial alternating current stimulation synchronizes the neural oscillations to the applied stimulation frequency in the stimulated cortical regions. In this report, we have reviewed the literature pertinent to the clinical application of tACS in psychiatric disorders; in addition, we have described the clinical use of online theta tACS in a schizophrenia patient with cognitive deficits. Online theta tACS led to improvement in working memory, attention, processing speed, and emotional processing. The beneficial effect of tACS persisted during reassessment of the patient after 50 days. Transcranial alternating current stimulation, given its noninvasiveness, safety, and ease of administration, has the potential to ameliorate cognitive deficits in neuropsychiatric disorders like schizophrenia.
