The mental health dangers of birth hypoxia
Philadelphia, PA, October 27, 2008 Complications during pregnancy and birth, such as birth hypoxia - the shortage of oxygen in the body - are associated with an increased risk for schizophrenia. However, it is not clear why hypoxia increases the risk for schizophrenia. The November 1st issue of...Mount Everest to be Site of Research into Hypoxia
