ObjectiveTo assess prospectively the prevalence of impulse control disorders (ICD), psychiatric symptoms, and their clinical correlates in patients with prolactinoma receiving dopamine agonists (DA) in comparison to those with non-functioning pituitary adenomas (NFA) and healthy controls (HC).MethodsA total of 25 patients with prolactinoma, 31 with NFA, and 32 HCs were included in the study. All patients and controls were screened for the presence of ICDs and other psychiatric disorders using revised version of Minnesota Impulsive Disorders Interview (MIDI-R), Barratt Impulsiveness Scale (BIS-11), Symptom Check List (SCL-90-R) questionnaire and Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI).ResultsWe detected two new cases (8%) of ICD associated with DAs. Both cases presented with hypersexuality, which reversed totally or decreased upon discontinuation of the drug. The re-challenge of the DA in a smaller dose has led to either no symptoms or weaker symptoms than before. There was an increase in the number of patients who screened positive on obsession, interpersonal sensitivity, paranoid ideation, and additional items subscales of SCL-90-R in comparison to HCs at the end of the study period (p<0.05 for all). Likewise, cumulative DA dose was positively correlated to obsession, interpersonal sensitivity, paranoid ideation, hostility, phobic anxiety subscales, and GSI scores of SCL-90-R (p<0.05 for all).ConclusionsDAs are associated with a small but substantial short-term risk of ICD development and a broad range of psychiatric symptoms in patients with prolactinoma receiving DAs.
