Women with high blood pressure during pregnancy had sons with impaired mental ability, especially in math. The study only looked at sons, but one can assume it also applies to daughters.

Mom's High Blood Pressure in Pregnancy Could Affect Child's IQ Into...

New research suggests that a mother's high blood pressure during pregnancy may have an effect on her child's thinking skills all the way into old age.

"High blood pressure and related conditions such as preeclampsia complicate about 10 percent of all pregnanciesand can affect a baby's environment in the womb," said study author Katri Räikönen, PhD, with the University of Helsinki in Finland. "Our study suggests that even declines in thinking abilities in old age could have originated during the prenatal period when the majority of the development of brain structure and function occurs."

The study found that men whose mothers had high blood pressure while pregnant scored 4.36 points lower on thinking ability tests at age 69 compared to men whose mothers did not have high blood pressure. The group also scored lower at the age of 20 and had a greater decline in their scores over the decades than those whose mothers did not have problems with blood pressure. The finding was strongest for math-related reasoning. [emphasis mine]
