One of the non-motor features of idiopathic Parkinson’s disease (IPD) is sexual dysfunction (SD) which is under-recognized and, consequently, undertreated. This study aimed to evaluate SD in patients with IPD.
Patients and methods
The study was conducted on 67 IPD patients; 30 healthy subjects with age and gender matching with the patients served as the control group. All participants were subjected to sexual function assessment using the Arabic version of Arizona Sexual Experience Scale (ASEX), Mini-Mental State Examination (MMSE), and Beck Depression Inventory (BDI), while the severity of IPD was assessed using the modified Hoehn and Yahr scoring scale and MDS-Unified Parkinson’s Disease Rating Scale (MDS-UPDRS).
Results
There were no statistically significant differences between patients with IPD and the control group regarding MMSE, hypertension, diabetes mellitus, or dyslipidemia. However, BDI scores were significantly higher in patients with IPD. The rate of SD among our patients was 64% compared to 30% in the control group. The total score and subscales of ASEX were significantly higher in IPD patients than in controls. SD showed a significant correlation with the severity of the IPD irrespective of other variables, including patient age, sex, disease duration, hypertension, diabetes, dyslipidemia, smoking, and dose of L-dopa.
Conclusion
SD is a commonly underrated feature in patients with IPD; it should be investigated carefully as it is an important non-motor symptom that correlates with disease severity.
