Suppression of complex visual hallucinatory experiences by occipital transcranial magnetic stimulation: a case report

Neurocase. 2003 Oct;9(5):436-40. doi: 10.1076/neur.9.5.436.16557.


Abstract We report a patient with visual hallucinations and illusions along with an associated visual field defect after bilateral ischemic damage to his occipital visual cortex. These hallucinations were long-standing and of both simple and complex (well-formed) type. Application of low frequency (1 Hz) repetitive Transcranial Magnetic Stimulation (rTMS) to the occipital cortex led to a complete cessation of visual hallucinatory symptoms. The use of TMS to probe the neurophysiology, and possibly alleviate, visual hallucinatory experiences is discussed.
