Rorschach test with resting digital EEG and brain mapping

Key findings

  • Mild Rorschach signs (70 patients) went with subtle but specific changes, such as poorly organized alpha and mild frontal-temporal paroxysmal activity
  • Moderate signs (70 patients) went with disorganized EEGs, focal slow delta/theta activity and spreading paroxysmal activity
  • Marked signs (70 patients) went with well-defined cortical structural lesions seen on digital EEG and brain mapping
  • Eyes-closed EEG was recorded from 19 electrodes (10/20 system); groups were compared with F and Student t tests

A Cuban study comparing signs of organic brain impairment on the Rorschach inkblot test with digital EEG and brain mapping in 210 patients with neuropsychiatric problems following head trauma, meningoencephalitis or epilepsy. Patients were divided into three equal groups by the number of Rorschach organic signs (mild, moderate or marked). The authors report that EEG abnormalities became more pronounced in step with Rorschach severity, from subtle electrical changes to well-defined cortical lesions.
