case report Misophonia, i.e. hatred of sound, is a relatively unknown condition and hence usually overlooked and misdiagnosed. In this lecture, we describe three patients with misophonia and hypothesize about its neurobiological mechanisms. We present a 28-year-old woman with hatred of breathing sounds, a 35-year-old woman and a 48-year-old man, both with hatred of eating sounds.  Personality characteristics include obsessive-compulsive personality traits, with perfectionism, rigidity and high moral values. Misophonia probably emerges during adolescence following of conditioning of a specific traumatic event.
method These case reports support the idea that misophonia is more common than expected and is part of obsessive-compulsive spectrum disorders. We anticipate an increasing incidence due to growing population density and increasing sound production by our society. More research is needed to support these hypotheses.
