Navigating Sex-Specific Disease Dynamics in Incident Dementia

Area of Science:

• Gerontology and Neurology
• Public Health and Epidemiology

Background:

• Dementia is a major cause of cognitive and functional decline in older adults.
• Previous research indicates potential sex differences in health conditions and cognitive decline progression.
• Limited research exists on the temporal evolution of health conditions after a dementia diagnosis.

Purpose of the Study:

• To analyze shifts in medical conditions post-dementia diagnosis.
• To examine sex-specific temporal patterns of chronic health conditions.
• To identify how health conditions evolve over a 15-year period around diagnosis.

Main Methods:

• Utilized a 15-year window (5 years pre-diagnosis, 10 years post-diagnosis).
• Introduced MedMet, a network metric for quantifying medical condition contribution.
• Employed growth and decay functions for temporal trajectory analysis.

Main Results:

• Identified specific health conditions with higher prevalence in females compared to males.
• Demonstrated distinct temporal patterns of chronic conditions between sexes after dementia diagnosis.

Conclusions:

• Findings highlight significant sex differences in health conditions following dementia diagnosis.
• Emphasizes the need for sex-specific approaches in dementia care and healthcare planning.
• Sex-based disparities may influence healthcare utilization patterns in dementia patients.
