Sleep

This volume comprises five sections: the first looks at the semiotics of normal sleep in adults and children, sleep mechanisms and the major physiological functions and mental activity during sleep. The second section is a review of the different means of investigating sleep and wakefulness and the methods of analysis currently available. The third section deals with the disorders of sleep and wakefulness, insomnias, hypersomnias, circadian rhythm sleep disorders and parasomnias. The fourth section describes a number of medical disorders which are either sleep-related or simply exacerbated by sleep: snoring, chronic obstructive lung diseases, restless legs syndrome or periodic limb movement disorder, sleep epilepsies, etc. The final section encompasses disorders which are not sleep-dependent but to which sleep investigations may add further insight, such as mood disorders, certain neurological pathologies, dysautonomias, and again, epilepsy.§The appendix contains questionnaires, indexes, and assessment scales designed to assist the clinician in evaluating the different disorders. The present edition, written in English is a complete revision of the two preceding French editions. It represents the work of European and North and South American specialists.
