Test–Retest Reliability of the Multiple Sleep Latency Test in Central Disorders of Hypersomnolence

Abstract

The PSG-MSLT measures and classification are not stable in patients with NCHS, with frequent diagnostic changes, particularly for NT2 and IH, compared with NT1. MSLT needs to be repeated at regular intervals to confirm a stable hypersomnia and provide an accurate diagnosis of NT2 and IH.
