Abstract Previous research revealed that children born from threatened abortion (TAB)-affected gestation are at 2-3 fold increased risk of autism spectrum disorders and developmental coordination disorder. In conventional cohort analysis, TAB-affected children had a 21-25% higher relative risk of epilepsy, attention-deficit/hyperactivity disorder (ADHD), in the first 16 years of life and 42% higher relative risk of cerebral palsy in the first 6 years of life.
