Researchers looked at the medical records for mothers’ blood pressure during pregnancy. They checked 398 men. They tested their abilities at age 20 and again at age 69. The tests checked language skills, math reasoning, and visual and spatial relationships.
It turned out that those men whose mothers had high blood pressure while pregnant scored 4.36 points lower on thinking ability tests. The group also scored lower at the age of 20 and had a greater decline in their scores over the decades. The finding was strongest for math-related reasoning.
