Oxygen Therapy in Schizophrenia
Due to intense ATP-consuming processes in the brain, a high level of brain energy supply is required. A popular hypothesis regarding the pathogenesis and pathophysiology of schizophrenia postulates hypofunction of neuronal circuits in the prefrontal and limbic-temporal areas. An emerging body of data suggests that impaired energy metabolism due to mitochondrial dysfunction plays a role in the pathophysiology of schizophrenia.
Under normal conditions cellular metabolic rate, i.e. oxygen and glucose consumption, increases proportionally with any increase in neuronal activity. The impaired energy metabolism due to mitochondrial dysfunction and frontal lobe hypofunction might be improved by increasing O2 supply to the brain. Oxygen-enriched air inhalation has been shown to increase brain oxygen supply. Hyperoxia therapy is a useful tool in the treatment of neurological and neurotrauma deficits.
We therefore suggest a randomized double blind cross-over study of enriched inspired O2 partial pressure in schizophrenia.
It is surprising given the numerous findings on reduced energy metabolism in schizophrenia that simple treatment with inspired enriched oxygen has not been studied.

To compare the efficacy of long-term use of nocturnal oxygen therapy (12 hours) with that of continuous, low-flow oxygen therapy (24 hours) in patients with chronic hypoxic lung disease.
The primary aim was to determine whether the presence of metabolic syndrome (MetS) limits aerobic fitness in patients with schizophrenia. A secondary aim was to investigate the associations between ae...
Schizophrenia is a chronic and often debilitating illness which affects about 1% of the world population. Some reagents have been used to simulate schizophrenic disorders in laboratory animals, such a...
Neuropsychiatric conditions like schizophrenia display a complex neurobiology, which has long been associated with distributed brain dysfunction. However, no investigation has tested whether schizophr...

Medical and Biotech [MESH] Definitions
A chronic form of schizophrenia characterized primarily by the presence of persecutory or grandiose delusions, often associated with hallucination.
A long-acting injectable antipsychotic agent used for chronic schizophrenia.
A large increase in oxygen uptake by neutrophils and most types of tissue macrophages through activation of an NADPH-cytochrome b-dependent oxidase that reduces oxygen to a superoxide. Individuals with an inherited defect in which the oxidase that reduces oxygen to superoxide is decreased or absent (GRANULOMATOUS DISEASE, CHRONIC) often die as a result of recurrent bacterial infections.
A type of schizophrenia characterized by abnormality of motor behavior which may involve particular forms of stupor, rigidity, excitement or inappropriate posture.
An obsolete concept, historically used for childhood mental disorders thought to be a form of schizophrenia.
