Delusional disorder, somatic type treated with aripiprazole--mirtazapine combination.

Delusional disorder, somatic type (DDST) is a rare psychiatric disorder and the treatment is mostly based on observations, due to the lack of well-organized studies. Initially, antipsychotics and especially pimozide were considered to be the pharmacological approach of choice but, subsequently, tryciclic anti-depressants and selective serotonin re-uptake inhibitors (SSRIs) were also suggested to be effective, implicating the serotonergic system in the pathophysiology of the disorder. We present the case of a female with DDST, who responded to aripiprazole-mirtazapine combination, a finding that is in accordance with the initial approach of this disorder as a part of the schizophrenic spectrum, but also supports the hypothesis of serotonin dysfunction in DDST.
