Sexual dysfunction in men with young onset Parkinson's disease

Area of Science:

• Neurology
• Urology
• Psychiatry

Background:

• Sexual dysfunction (SD) is an under-reported non-motor symptom in Parkinson's disease (PD).
• Research on SD in young-onset Parkinson's disease (YOPD) is limited, particularly in India.
• Common SD symptoms in male PD patients include erectile dysfunction, premature ejaculation, and decreased libido.

Purpose of the Study:

• To determine the frequency of sexual dysfunction in men with YOPD.
• To explore the correlation between SD and other motor and non-motor symptoms in YOPD.
• To investigate the impact of SD on health-related quality of life (HR-QoL) in YOPD patients.

Main Methods:

• Prospective cross-sectional study of 62 male YOPD patients at NIMHANS, Bangalore.
• Diagnosis of YOPD based on MDS criteria for IPD 2015.
• Sexual function assessed using ASEX, PEDT, QUIP-RS, and sex hormone assays; motor and non-motor assessments also performed.

Main Results:

• 46.8% of YOPD patients experienced erectile dysfunction and 71% had premature ejaculation.
• 9.7% of cases exhibited hypersexuality.
• Longer YOPD duration predicted erectile dysfunction and premature ejaculation; SD correlated with anxiety, depression, and reduced HR-QoL.

Conclusions:

• Sexual dysfunction is highly prevalent in male YOPD patients.
• SD is linked to disease duration, psychological factors, and diminished quality of life.
• Neurological assessment for YOPD should routinely include screening and management of sexual dysfunction.
