BACKGROUND: Hyperprolactinemia causes hypogonadotrophic hypogonadism. Hyperprolactinemia can be pre-existing in some patients with schizophrenia. Dopamine is the most important prolactin-inhibiting factor, and dopaminergic hyperactivity has been implicated in the pathophysiology of psychosis. OBJECTIVE: Since dopamine is a prolactin-inhibiting factor and dopamine imbalanced has been implicated in the pathophysiology of psychotic disorders, we investigated the probable relationship between hyperprolactinemia and the development of psychotic symptoms, in a patient with hypogonadism due to hyperprolactnemia and subsequent first episode of psychosis. Since dopamine is a prolactin-inhibiting factor and dopamine imbalance has been implicated in the pathophysiology of psychotic disorders, we investigated the probable relationship between hyperprolactinemia and the development of psychotic symptoms. METHODS: We present the case of a patient with hypogonadism secondary to chronic, untreated hyperprolactinemia who developed acute psychotic symptoms. RESULTS: Psychotic symptoms resolved soon after treatment with aripiprazole in conjunction with cabergoline, with a concomitant decrease in serum prolactin level. CONCLUSION: This is an interesting case illustrating a complicated relationship among hypogonadism secondary to a prolactinoma and dopamine and psychosis.
