Abstract:
In the 24/7 modern society, sleep disorders and the role of normal amounts and timing of sleep for health are often neglected by both doctors and their patients.

This review will cover some of the recent papers published in both the Journal of Neurology and elsewhere in 2013/2014 that have advanced our knowledge of sleep and circadian rhythm disorders.
