Temperament and prodromal symptoms prior to first manic/hypomanic episodes: Results from a pilot study

We present data, which indicate a relationship between cyclothymic and irritable temperament and prodromal symptoms prior to the first manic/hypomanic episode. These findings support the notion that assessing cyclothymic temperament to identify people at-risk of developing bipolar-I and -II disorder may help to increase the predictive validity of applied at-risk criteria.
