ABSTRACT

The authors describe the Kline-Levin Syndrome (KLS) and point out the difficulties regarding its diagnosis. A clinical case of a 16-year-old boy diagnosed and followed by the authors is presented. Although having the classic trilogy (hypersomnolence; hyperphagia; hypersexuality), this is an illustrative case of such difficulties under several distinct clinical forms. Causes and consequences raised by diagnostic difficulties are discussed, with special attention to aspects concerning differential diagnosis.
