OBJECTIVE: To investigate the concept of 'Non-affective Acute Remitting Psychosis' (NARP) in a group of patients with first episode psychosis in Iran. METHOD: This is a 24-month follow-up study of 54 patients with first-episode psychosis admitted consecutively to a psychiatric hospital in Tehran, Iran. At the end of follow-up, consensus judgments were made on fulfillment of the NARP criteria as well as illness course and treatment. NARP was defined as a psychotic illness with acute onset (developed within 1 week), short duration (remission within 6 months), and the absence of prominent mood symptoms. RESULTS: Of 49 patients who completed the follow-up, 15 (30.6%) had NARP, accounting for 60% of non-affective psychoses. Ten patients with NARP remained relapse free, four had a very short-lived relapse, and only one developed a chronic illness. Throughout the follow-up, patients with NARP received fewer months of treatment than did patients with other non-affective psychoses. CONCLUSION: The high proportion of NARP among patients with first episode psychosis, and the favorable course is in keeping with previous studies in developing countries.
