Overview

The objectives of this study are: (1) to describe the detailed clinical characteristics and prognosis of ASPP patients in order to explore the risk factors of ASPP, and to compare the short-term and long-term functional recovery outcomes between them and their controls; (2) to evaluate the risk of recurrent stroke, particularly during subsequent pregnancies, in ASPP patients; (3) to assess the short-term and long-term outcomes of their offsprings and their future development status.

This study is divided into three parts. The first part is a case-control study to explore the risk factors of ASPP and the predictors of the prognosis of ASPP patients. The second part is a cohort study to evaluate the impact of ASPP on the risk of recurrent stroke. The third part is a cohort study to assess the impact of ASPP on the short-term and long-term outcomes of their offsprings by comparing the offsprings of ASPP patients with the offsprings of non-ASPP participants.
