Administering additional oxygen improves the function of brain's blood vessels in dementia patients suffering with lung disease finds a study. Research have showed that individuals with chronic obstructive pulmonary disease (COPD) are at a higher risk of dementia. This could be due to lower brain oxygen levels as a result of problems with blood supply from blood vessels in the brain. The study published in Experimental Physiology proved that oxygen therapy improves cerebral oxygen delivery and neurovascular function in chronic obstructive pulmonary disease patients. This improvement in cerebral oxygen delivery and neurovascular function might provide a physiological link between oxygen therapy
