It looks like encephalitis, but it is Kleine-Levin syndrome

Kleine-Levin syndrome is a rare disease characterized by recurrent episodes of hypersomnia and cognitive and behavioural changes. We present the case of a female patient aged 13 years who, following infection by influenza A virus, presented with disorientation, incoherent speech, bradypsychia, behavioural changes, somnolence and apathy. No history of trauma or toxic substance exposure. Kleine-Levin or “sleeping beauty” syndrome has an unknown aetiology and a good prognosis with progressive resolution with age. There is no curative treatment, but corticosteroids have been used during episodes and preventive treatments like lithium and modafinil.
