Gender differences in Parkinson's disease symptom profile

Area of Science:

• Neurology
• Clinical Medicine
• Patient Reported Outcomes

Background:

• Parkinson's disease (PD) is a neurodegenerative disorder affecting motor and non-motor functions.
• Understanding gender-specific symptom presentation in PD is crucial for personalized management.
• Previous research has not fully elucidated the nuanced differences in symptom experience between genders.

Purpose of the Study:

• To investigate and compare gender differences in the prevalence and experience of Parkinson's disease symptoms.
• To identify early and current symptom profiles in male and female PD patients.
• To evaluate the utility of a symptom profile instrument for PD management.

Main Methods:

• A questionnaire-based study was conducted on 948 individuals diagnosed with Parkinson's disease.
• Participants reported on the most common PD symptoms at disease onset (SP-1) and currently (SP-2).
• Symptom data were analyzed to identify differences in frequency between male and female subjects.

Main Results:

• Common symptoms for both genders included tremor, fumbling, writing difficulties, rigidity, and fatigue.
• Females reported higher frequencies of neck and low back pain at onset.
• Males reported more frequent writing difficulties, fumbling, gait issues, speech problems, drooling, and lack of initiative.
• Sleep disturbances like inability to turn in bed and calf cramps were prevalent in both sexes.
• Depression was a constant distress for many females, impacting treatment compliance.
• A significant portion of patients (approx. 30%) did not report classic PD symptoms like tremor and rigidity.

Conclusions:

• Parkinson's disease presents with distinct gender-specific symptom profiles.
• A comprehensive symptom profile instrument can aid in detecting medication errors and improving patient outcomes.
• Tailoring management strategies based on gender-specific symptoms may enhance quality of life for individuals with PD.
