title: Dimensions of sexual dysfunction in Parkinson disease.
abstract: OBJECTIVE
  The authors sought to better understand the factors related to sexual dysfunction in Parkinson disease (PD).
  
  
  METHODS
  Twenty-one PD patients and their partners received the Derogatis Interview for Sexual Functioning-Self Report (DISF-SR). Additional measures assessed disease severity, autonomic dysfunction, mood, and social circumstance.
  
  
  RESULTS
  Data from 17 male patients demonstrated profound impairment in the dimensions of sexual arousal, behavior, orgasm, and drive, with most patients scoring below the 1st percentile on these Derogatis Interview subscales. All four dimensions showed significant intercorrelations. In contrast, 53% of patients scored above the 50th percentile in sexual fantasy. Sexual fantasy subscale scores were positively correlated with duration of PD.
  
  
  CONCLUSIONS
  The usefulness of the DISF-SR in this PD population was limited by extremely low scores and strong correlations among the subscales. The increase in sexual fantasy with greater PD duration suggests that patients with advancing disease remain interested in sex and that sexual dysfunction in PD is clinically relevant in this group.
