title: [Kleine-Levin syndrome is a diagnostic challenge].
abstract: Kleine-Levin syndrome (KLS) is a rare disorder characterized by recurrent episodes of hypersomnia, disturbed behaviour, and cognitive function; it may by accompanied by hyperphagia/hypersexuality. KLS is often seen after a minor infection in young men but the aetiology is unknown. This case rapport illustrates how a 16-year-old boy with ADHD presented with a range of the above-mentioned symptoms and was assessed by neurologists, internal medicine doctors and psychiatrists. After two new episodes he was finally diagnosed with KLS. The understanding of this disorder is intriguing.
