Compounds in Green Tea May Protect Against Neurological Damage

Compounds in green tea may protect against neurological damage from obstructive sleep apnea, according to a new study.

For the study, researchers examined the effects green tea polyphenols (GTP), administered through drinking water, on rats who were intermittently deprived of oxygen during 12-hour "night" cycles, mimicking the intermittent hypoxia (IH) that humans with OSA experience.

People with OSA have been reported to have increased markers of oxidative stress and exhibit architectural changes in their brain tissue in areas involved in learning and memory.
