Abstract

Persistent delusional disorder in which delusions are the most prominent psychopathology, comprises a well described clinical entity in psychiatry. Although the functional impairment is hardly evident unlike in schizophrenia, mood disturbances are one way of the presentation. Depressed mood even with sufficient criteria to diagnose a depressive episode can be a presenting feature. Although DSM 5 mention that patients with persistent delusional disorder can present with a manic episode, reported such cases are rare. It is important to identify the persistent delusional disorder presenting as manic episodes, as this uncommon presentation may mask the underlying major diagnosis.
