43. Insomnia Disorder: Why You're Tired but Can't Switch Off

If you were told, right now, that you could lie down and fall asleep within five minutes, would your body actually believe you? For most people with insomnia, the honest answer is no, and that gap sits at the centre of the entire disorder. In this episode, we open a five part series on sleep disorders, classified according to ICD-11. We cover how insomnia disorder is actually defined and diagnosed, the two-process model of normal sleep, the hyperarousal model and Spielman's 3P model of how insomnia develops and persists, what investigations are genuinely useful, and current NICE-guided management, from sleep hygiene and CBT-I through to the Z-drugs, melatonin, and the newest licensed option, daridorexant. Ideal for MRCPsych Part A revision, psychiatry trainees, medical students and anyone who has ever lain awake exhausted but unable to switch off.  Aligned with the Royal College of Psychiatrists MRCPsych Part A syllabus, paragraph 1.1.10, and the ICD-11 classification of sleep-wake disorders. I would love to hear from you! (https://www.buzzsprout.com/2596662/fa...)
