Hyperventilation Leading to Hallucinations

Hyperventilation Leading to Hallucinations THOMAS E. ALLEN M.D. 1 , and BERTRAND AGUS M.D. 2 1 Chief resident in child psychiatry, Columbia Presbyterian Medical Center, New York City 2 Chief medical officer, Federal Correctional Institution, Lompoc, Calif. The authors present two cases in which hyperventilation repeatedly led to hallucinations. They consider possible mechanisms and discuss their implications for the understanding of hallucinatory phenomena in schizophrenics, normals, and members of primitive societies. Four factors may be significant in determining whether hallucinatory phenomena will occur and in which sensory modalities: 1) the neurological integration of the individual; 2) the cerebral-vascular reactivity and pattern; 3) local cerebral requirements for oxygen and the capacity for extraction of it; and 4) the respiratory rate and buildup in hyperventilation. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png American Journal of Psychiatry American Psychiatric Publishing, Inc (Journal)
