The Lifespan Sleep Disorder Group at Guy's and St Thomas' provides specialist services for children and adults with rare disorders characterised by excessive daytime sleepiness (often called hypersomnia).
Narcolepsy and Kleine Levin syndrome are two examples of disorders we see.
Children and young people with the conditions are cared for by a multidisciplinary team (a team made up of different healthcare professionals), with support groups, and school input.
At 16 they are then moved smoothly to adult services through special transitional clinics.
Please see our referrals page if you'd like to refer anyone with excessive daytime sleepiness.
