Risk factors for motor complications in female patients with Parkinson's disease

Objective To investigate the risk factors of motor complications in female patients with Parkinson's disease (PD) and the correlation between the occurrence of motor complications and sex hormone levels. Methods According to the occurrence and types of motor complications, 103 female PD patients were divided into two groups: patients with or without the wearing-off phenomenon, patients with or without dyskinesia. Binary logistic regression analysis was performed respectively to screen for the risk factors of the wearing-off phenomenon and dyskinesia in female PD patients. Results Among 103 female PD patients, 44 (42.72%) had motor complications. Patients with the wearing-off phenomenon and patients with dyskinesia had higher prolactin levels than patients without the wearing-off phenomenon and patients without dyskinesia, respectively. However, the difference was no longer significant when the two groups were corrected for multiple comparisons (P < 0.0028). Multivariate analysis found that younger age at onset and higher Hoehn-Yahr (H&Y) stage were identified as independent risk factors for the wearing-off phenomenon and younger age of onset was an independent risk factor for dyskinesia in female PD patients (P < 0.05). Conclusion Female PD patients have a higher incidence of motor complications. Younger age of onset and higher H&Y stage were the risk factors of the wearing-off phenomenon, and younger onset age was the risk factor of dyskinesia in female PD patients. There may be a certain correlation between the occurrence of motor complications and sex hormone levels in female PD patients, which requires further verification.

Automated summary

This study investigated the risk factors and correlation between motor complications and sex hormone levels in female Parkinson's disease (PD) patients. The results showed that female PD patients had a higher incidence of motor complications. Younger age of onset and higher Hoehn-Yahr (H&Y) stage were identified as risk factors for the wearing-off phenomenon, and younger age of onset was a risk factor for dyskinesia in female PD patients. There may also be a correlation between the occurrence of motor complications and sex hormone levels in female PD patients, but further confirmation is needed.
