Sleep And Its Derangements

By William Alexander Hammond

Book Overview

Sleep and its derangements examines the physiological and pathological aspects of sleep as understood through the lens of medical science. It offers a comprehensive inquiry into the biological necessity of sleep, arguing that mental and physical health rely on it for restorative balance. The book contends that sleep allows the brain to replenish what it loses during periods of activity, suggesting that extended wakefulness exhausts cerebral resources essential for proper functioning. In the opening chapters, the argument centers on sleep as a state not of complete inactivity, but of partial suspension where unconscious mental processes continue in altered form. This concept, termed unconscious cerebration, proposes that thought may persist without conscious awareness, albeit with diminished coherence. The text introduces this idea to pave the way for more detailed discussions of sleep disorders, including insomnia, nightmares, sleepwalking, and the broader neurological consequences of disrupted rest. With references to both physiological observation and clinical insight, the work presents sleep as a complex, semi-conscious state vital to human cognition and physical vitality.
