Figure 2. Symptoms in obstructive sleep apnoea.

Most symptoms (Figure 2) are a consequence of sleep disruption. Recurrent arousals fragment sleep and, although SWS may be entered briefly between arousals, it is not adequately refreshing. The role of hypoxaemia in the development of the mental symptoms is unclear. It is possible that some aspects of cognitive dysfunction relate more to hypoxaemia than to sleep disruption.
