Untreated major depressive disorder with and without atypical features: a clinical comparative study.

Aims And Method: A comparative study of major depression with and without atypical features (as per DSM IV TR criteria) was planned to assess illness characteristics, resulting dysfunction and co-morbidities, which can have important implications in its management. Serially, 107 newly registered patients with depression not taking any treatment for at least a month were included. Patients with psychotic features in present or past, known bipolar disorder and likely organic aetiology were excluded.
