Catathrenia is a rare sleep disorder characterised by groaning and prolonged expiration confined to sleep alternating with normal breathing that may occur at all sleep stages. After its first description in 1983 [1], catathrenia was recently introduced into the International Classification of Sleep Disorders [2]. Although the exact pathogenesis remains unknown, catathrenia has been considered a...

In spite of tremendous advances in medical science, sleep has not been understood completely. The causes for many of parasomnias are still not evident. Even then these parasomnias are treated with different drugs, one of the major groups among them being sedative hypnotics. The use of sedative hypnotics are always associated with adverse effect, and there is many a times loss of the normal slee...

In this paper, we present two carefully documented cases of patients with sleep-related eating disorder (SRED), a parasomnia which is characterized by involuntary compulsive eating during the night and whose pathophysiology is not known. Using video-polysomnography, a dream diary and psychometric examination, we found that both patients present elevated novelty seeking and increased reward sens...

BACKGROUND Catathrenia was recently defined as a parasomnia in the International Classification of Sleep Disorders Diagnostic and Coding Manual (ICSD-2), but there is debate about its c...

There is some controversy as to whether SRED and NES are similar disorders situated at opposite ends of a common spectrum of pathophysiology, with different leve...
