Sleep Disorders
category
Sleep disorders are clinical conditions that systematically impair sleep quantity, quality, timing, or behavioral safety — including insomnias (difficulty initiating or maintaining sleep), sleep-disordered breathing (obstructive and central sleep apnea), movement disorders (restless legs syndrome, periodic limb movement disorder), circadian rhythm disorders (delayed sleep phase syndrome, shift work disorder), parasomnias (sleepwalking, REM sleep behavior disorder, night terrors), and hypersomnia conditions (narcolepsy, idiopathic hypersomnia) — each requiring specific evaluation and treatment.
Role
Sleep disorders are massively underdiagnosed — with obstructive sleep apnea alone estimated to affect 25–30% of adults in developed countries but diagnosed in fewer than 20% of those affected. The majority of people experiencing genuine sleep disorders have adapted to their impaired baseline and either attribute their symptoms to normal aging, stress, or character traits, or have unsuccessfully attempted behavioral interventions for conditions that require clinical treatment. The generalist who understands the landscape of sleep disorders can recognize when their own sleep problems exceed what behavioral optimization can address and when professional evaluation is warranted.
