Today we dive into two rare but life-disrupting sleep disorders: narcolepsy and idiopathic hypersomnia. People with these conditions don’t just feel tired — they can fall asleep suddenly while driving, talking, or working, or sleep 11+ hours and still feel completely unrefreshed with intense brain fog and sleep drunkenness. Our guest is world-renowned sleep expert Dr. Logan Schneider, board-certified neurologist and sleep medicine specialist, Adjunct Clinical Associate Professor at Stanford University, and Clinical Lead for Sleep Health at Google. We cover causes (including the loss of the brain chemical orexin/hypocretin), symptoms like cataplexy, diagnosis, the only FDA-approved medication for idiopathic hypersomnia (Xywav), made by Jazz Pharmaceuticals @JazzPharma, lifestyle strategies, common myths, and how to find the right specialist.
