Cocaine during pregnancy can lead to cognitive impairments in kids like attention insufficiency, learning disabilities and emotional problems. Research on rabbits postulated that prenatal cocaine exposure leads to a long lasting displacement of dopamine receptors in certain brain cells, which changes their ability to function normally. Doctors have also put forward that cocaine if taken with other drugs cause premature labour, preterm birth and low birth weight. In addition, if less dose of cocaine is taken during pregnancy then baby seems to be normal at birth but tend to develop cognitive impairment with growing age. Prior to this, scholars had discovered that exposure to low levels of intravenous cocaine during a very short span of time during gestation causes certain changes in brain circuits that use the neurotransmitter dopamine that is involved in regulating the formation of cortical circuitry.
Women who were underweight when they were born are at greater risk of pre-eclampsia during pregnancy. Pre-eclampsia is a common condition that causes high blood pressure and can put the mother’s life at risk. The result is based on a study of more than 6,000 women under the age of 30 years. The findings also gave a view that if their mothers too had pre-eclampsia, the risk was expected to be doubled. Thus, supporting the previous studies according to which pre-eclampsia run in families. Low birth weight is also believed to be related to other conditions associated with high blood pressure, such as heart disease.
