Look, you know this stuff… Three disorders – Insomnia, Sleep Walking, Narcolepsy Biological – Genetic – Higher concordance for the disorders across MZ twins suggests a genetic component Biological – Neural (SCN, Pineal Gland, Melatonin, Hypocretin) – Insomnia and Narcolepsy – when the endogenous aspects which influence sleep/wake are abnormal – Sleep Walking – Underdeveloped / abnormal neural structures which influence sleep, especially those which lead to paralysis Psychodynamic – Early trauma -> Unconscious Conflicts -> abnormal behaviours to overcome / escape from / revert to a time before trauma
