Cyclothymic temperament and major depressive disorder: A study on Italian patients

Our data confirm previous reports in a sample of accurately screened patients with unipolar major depression: we found that patients with a cyclothymic temperament had an earlier age at onset and a higher family history for bipolar disorder than patients without any dominant affective temperament. Further research is needed to ascertain whether patients with “unipolar” cyclothymic MDD respond to mood stabilizers.
