Sleep Disorders

Obstructive sleep apria (OSA) is a common problem that affects a person’s breathing during sleep. A person with OSA has time during sleep in which air cannot flow normally into the lungs. The block in air flow (obstruction) is usually caused by the collapse of the soft tissues on the back of the throat (upper air way) and tongue during sleep, American thoracic society (2017). OSA is more common in men, women after menopause and people who are over the age of 65.

It also occurs in children but more in adults than asthma. It still remains substantial but frequently ignored public health threat. Nitric oxide (NO) which is synthesized from L-arginine via endothelial Nitric oxide Synthesis (NOS) is a mediator that includes vasodilation, inhibits platelet aggregation and prevents adhesion of platelets to endothelial cell (spieker et al., 2000). High levels of glutamase in particular are associated with exatotoxicity, a probable mechanism of injury in some brain areas in OSA.
