In this cohort study, HDPs were associated with an increased risk of incident dementia after adjustment for baseline maternal, socioeconomic, and obstetric factors. However, this association was no longer statistically significant after additional adjustment for postdelivery vascular and metabolic conditions. Given the small number of dementia events among females with HDPs, these findings should be interpreted cautiously. These findings suggest that HDPs may serve as an early-life marker of long-term neurovascular vulnerability.
