According to the Wechsler Adult Intelligence Scale-fourth edition, patients with schizophrenia (SCZ) had poorer neurocognitive function compare to the general population. Clinical observations of cognitive impairment provide evidence that disturbed neuroplasticity in the pathophysiology of SCZ includes alterations in neurotransmitter systems and cortical connectivity. Repetitive transcranial magnetic stimulation (rTMS) is a safe and widely used non-invasive neuroscientific tool to investigate a variety of neurophysiological processes, including neuroplasticity. The therapeutic potential of rTMS in SCZ by stimulating and regulating the cortical function of the brain is beginning to show effects, but will require further study involving different trains of TMS pulses with various frequencies and intensities in the future.
