Know the Physiological Link Between Oxygen Therapy and Dementia
A physiological link can be found between oxygen therapy and reduction in risk of dementia with an improvement in the cerebral oxygen delivery and neurovascular function.
Research has proved that administering additional oxygen in individuals with chronic obstructive pulmonary disease (COPD), who are at a higher risk of dementia improves the function of the brain's blood vessels who suffer from lung disease.
Oxygen therapy, therefore, in chronic obstructive pulmonary disease patients improves the cerebral oxygen delivery and neurovascular function, and hence creates a psychological link between it and the reduction of risk of cerebrovascular diseases such as stroke, mild cognitive impairment, and dementia, in COPD.
The research team conducting the tests found that the blood vessels in the brain become dilated while responding to the greater oxygen demand when the brain is active because blood flow and oxygen delivery to the brain significantly increases.
