The disparity in Parkinson's disease manifestation between men and women: an exploratory analysis.
Parkinson's disease (PD) affects the lives of over 400,000 women in the US, a number that is expected to grow to 1.2 million by 2030 [1]. Women with PD often manifest symptoms at an earlier age and have a higher chance of developing a less severe form of the disease [2]. However, they face unique challenges in diagnosis, treatment, and prognosis compared to men.
Research shows that women's symptoms and responses to medication can differ from men's, necessitating gender-sensitive approaches in treatment plans [3]. Women are more likely to downplay the severity of their symptoms, leading to delayed accurate diagnoses and referrals to specialists [4]. This is particularly true for premenopausal women, whose hormonal cycles and PD symptom progression should be closely monitored [5].
In diagnosis, women tend to have lower initial rates and different age-related patterns of PD onset compared to men, which can affect timely recognition and management of the disease [2]. This, combined with the underrepresentation of women in advanced therapy cohorts like deep brain stimulation (DBS), suggests disparities in clinician referral patterns, patient preference, and psychosocial support networks [1].
Regarding prognosis, women may have a reduced quality of life linked to higher mood disorder prevalence and lower social support, which can negatively impact disease management and outcomes [1]. Cognitive assessment studies also emphasize the importance of sex-specific factors, as men and women show different patterns in subjective cognitive decline reports and cognitive symptoms in PD [4].
Environmental factors contribute to the development of PD, affecting women and men differently. Women may face a higher risk of indirect exposure to paraquat, a highly toxic herbicide associated with Parkinson's, when planting or harvesting crops [6]. Long-term exposure to toxic substances like trichloroethylene and polychlorinated biphenyl, often found in industrial occupations, increases the risk of Parkinson's [7].
To address these disparities, gender-tailored strategies are needed in PD diagnosis, treatment, and counseling. This includes customizing treatment for women's lower body weight and specific drug metabolism, tracking hormonal cycles and PD symptom progression, and increasing efforts to include women in clinical trials and research [1][3][4]. By doing so, we can improve outcomes for the growing number of women living with Parkinson's disease.

- Scientific studies highlight the significance of gender-sensitive approaches in managing Parkinson's disease, as women's symptoms and responses to medication may differ from men's.
- Research indicates that environmental factors, such as exposure to paraquat and trichloroethylene, may pose a higher risk to women in the development of Parkinson's disease, emphasizing the need for targeted health-and-wellness strategies in womens-health.
- To improve outcomes for women living with Parkinson's disease, a combination of gender-tailored strategies is necessary, such as customizing treatment based on women's unique medical-conditions, closely monitoring hormonal cycles and PD symptom progression, and including more women in clinical trials and research, as suggested by recent scientific literature.
