Sexual Dysfunction in Early-Onset Parkinson's Disease: A Cross-Sectional, Multicenter Study

Area of Science:

• Neurology
• Urology
• Sexual Medicine

Background:

• Sexual dysfunction (SD) is an understudied non-motor symptom in Parkinson's disease (PD).
• Early-onset Parkinson's disease (EOPD) presents unique challenges, including potential impacts on sexual health.
• Understanding SD in EOPD is crucial for comprehensive patient care.

Purpose of the Study:

• To assess sexual function in a cohort of patients with early-onset PD (EOPD).
• To compare sexual function in EOPD patients with a group of healthy controls.
• To identify factors associated with sexual dysfunction and dissatisfaction in EOPD.

Main Methods:

• Cross-sectional, multicenter study design.
• Utilized gender-specific questionnaires: The Brief Male Sexual Function Inventory (BSFI-M) and the Female Sexual Function Index (FSFI).
• Compared scores between 105 EOPD patients and 90 healthy controls, analyzing demographic and clinical variables.

Main Results:

• Sexual dysfunction (SD) was prevalent in 70.2% of EOPD patients versus 52.5% of controls.
• EOPD men reported lower scores in drive, erections, ejaculation, and satisfaction compared to controls.
• EOPD women showed lower FSFI scores, particularly in lubrication and pain domains; only 35.2% reported sexual satisfaction compared to 81.2% of controls.
• Multivariate analysis indicated gender, depression, and urinary dysfunction were associated with SD; gender, UPDRS, and urinary dysfunction were linked to sexual satisfaction.

Conclusions:

• Sexual dysfunction and dissatisfaction are more prevalent in EOPD patients than in the general population.
• Gender and urinary dysfunction are significant factors associated with SD and sexual dissatisfaction in EOPD.
• Further research and targeted interventions are needed to address sexual health concerns in EOPD.
