title: [Phenomenological differences between adolescent and adult onset mania: a comparative study].
abstract: OBJECTIVE
  The aim of this study is to determine the relationship between age of onset and phenomenology of bipolar affective disorder (mania).
  
  
  METHODS
  The current and retrospective diagnoses of the patients were made according to DSM-IV Bipolar Affective Disorder (mania) criteria. Sociodemographic features, clinical features, type of episode, number and length of hospitalizations were investigated in three groups which were consisted of adolescent-onset adolescents (n=60), adolescent-onset adults (n=60) and adult-onset adults (n=60). The groups were determined according to age of onset and current age categories. All patients have been assessed by Structured Clinical Interview for DSM-IV-Clinical Version (SCID-I), Young Mania Rating Scale (YMRS), Hamilton Depression Rating Scale (HAM-D) and Scale for the Assessment of Positive Symptoms (SAPS).
  
  
  RESULTS
  The groups were consisted of equal numbers of women and men. Rate of single (%51.7) and divorced patients (%21.7), rate of unemployment status (%70) were higher in adolescent-onset patients than adult-onsets. Adolescent-onset adolescents and adolescent-onset adults were different from adult-onset patients with respect to mixt episodes (%26.7, %15) and mood congruent or incongruent psychotic features (%35/%50, %31.7/%66.7) and length of hospitalization (23.9+/-4.8, 23.8+/-3.9).
  
  
  CONCLUSIONS
  Adolescent-onset of illness causes higher probability of mixt episodes, psychotic features such as mood congruent or incongruent hallucinations and delusions. This study supports the hypothesis that adolescent-onset mania may be a different subtype than adult-onset mania with respect to type of episode, phenomenology, and clinical features.
