Objective Age at onset in Parkinson's disease (PD) seems to be related nonmotor symptoms. In this study we investigated the effect of the age at onset on symptoms of sexual dysfunction (SSD) in patients with PD. Methods This prospective study comprised 22 consecutive outpatients with early onset PD (EOPD-onset of the disease before 55 years), and 66 outpatients with late onset PD (LOPD-onset of PD over 55 years). They were all recruited from the Department of Movement Disorders, Clinic of Neurology. The diagnosis was established according to the UK PD Brain Bank Criteria by a movement disorders specialist. The Unified PD Rating Scale (UPDRS) motor was used to assess motor disability and Hoehn and Yahr (H&Y) stage was used to establish disease severity. The sexual functions of the patients were rated by applying the Arizona Sexual Experiences Scale (ASEX). Results Thirteen EOPD patients (59.09 %) and 53 of the LOPD patients (80.3 %) (p 0.047) reported dissatisfaction with at least one item of ASEX. There were no differences between H&Y stages (p 0.205) UPDRS total (p 0.267) and motor scores (p 0.100) between groups. LOPD patients had significantly higher ASEX scores than EOPD patients (p 0.001). Interpretation Sexual dysfunciton occurs more frequently and more severely in LOPD than EOPD patients. PD patients with different ages at onset clinically present differently in terms of SSD.
