Hallucinatory and Delusional States in Connection with Blood Pressure and EEG

Summary Twenty-two patients who had low blood pressure with hallucinatory and delusional states were examined. Nineteen cases showed low voltage fast waves in EEG. By treatment with halo-peridol the symptoms as well as the blood pressure and EEG showed improvement. From the above findings, the hallucinatory and delusional states observed in this study may have a close connection with dysfunction of the lower brain or disharmony of function between the upper and the lower brains.
