... Since 1991, there has been a provisional International Classification of Sleep Disorders (ICSD) [6]. The two clinically most important groups of disorders are dyssomnias (intrinsic and extrinsic) and parasomnias. OSA is the most common intrinsic dyssomnia leading to hypersomnia. However, insomnia ma ...
