Oxygen loss leads to memory loss

Thursday, July 31, 2008

SAN DIEGO, Calif.--Obstructive sleep apnea could cause memory loss, say researchers from the University of California Los Angeles in the June 27 issue of the journal Neuroscience Letters. Researchers did MRIs on brain tissue called mammillary bodies and discovered that 43 OSA patients had smaller mammillary bodies than 66 study participants without the disease. The continuing lack of oxygen causes serious brain tissue damage that can lead to memory loss, say researchers. The memory problems continue even after patients receive sleep apnea treatment.
