enital symptoms are rarely reported in Parkinson disease (PD); however, when present, these are often severe and unrelenting, becoming the main source of disability. 1 Either male or female patients can be affected and, in most cases, the genital symptoms are subjectively described as a discomfort, pain, numbness, vibration, restlessness, or burning sensation involving the vagina, perineum, pelvis, and proximal portion of the lower limbs. Similar symptoms have been reported in drug-induced parkinsonism (tardive pain), 2 atypical parkinsonian syndromes, 1 and otherwise healthy individuals. 3 In patients with PD, the genital discomfort has been attributed to wearing-off nonmotor fluctuations and dopaminergic denervation. 4 In patients without PD, a syndrome of persistent sexual arousal was described in 2001. 5 The clinical criteria for this were defined as an involuntary genital arousal that persists for an extended period (hours to months), does not go away with 1 or more orgasms, is unrelated to feelings of sexual desire, is intrusive and unwanted, and is associated with significant distress. 6 The pathogenesis had been speculated by several authors until 2009, when preexisting or coexisting restless leg syndrome (RLS) was found in 12 of 18 patients and the term restless genital syndrome (RGS) was introduced. 3 Therapeutic approaches have included clonazepam, oxazepam, tramadol hydrochloride, antidepressants, estrogens, psychotherapy, transcutaneous electrical nerve stimulation, and even clitoridectomy, 3 with poor results. We report a patient with PD and severe genital discomfort unrelated to motor fluctuations but with a clear circadian rhythm and response to pramipexole, compatible with RGS.
