title: [Clinical-psychopathological and electroencephalographic studies on patients with delusions of the paranoic and the paraphrenic types].
abstract: Clinical-psychopathological and electroencephalographic investigations are reported, carried out on patients with delusions of the paranoic and of the paraphrenic types. Abnormal EEGs were found more frequently in patients with a paraphrenic syndrome, and there was also a relatively more frequent response to flickering lights than in the paranoic group. There was also a more frequent response to flicker in patients with auditory hallucinations. Psychopathologically more florid delusional syndromes appear to produce abnormalities in the EEG more readily than do psychopathologically less elaborate syndromes.
