Module 4 discussion

Stress and the Reproductive System

Does maternal stress have an influence on the cognitive development of the fetus? This question has intrigued researchers for many years and continues to be an area of ongoing research. Exposure of pregnant females to stress has been hypothesized to lead to many prenatal effects from fetal disorders to pregnancy failure. Studies have suggested a potential link of prenatal stress to attention deficit hyperactivity disorder (ADHD), schizophrenia, and autism in offspring.

A study conducted in 2009 demonstrated that prenatal maternal stress during the second trimester, as the result of exposure to a Canadian Ice storm, resulted in greater dermatoglyphic asymmetry (different dermal ridge counts) in their children. This asymmetric pattern is sometimes found in patients with schizophrenia. This finding is of particular interest as the fingerprint pattern of fetuses develops at the same time as the hippocampus in utero, and may be a physical marker for altered development of this region.

Chose one of the disorders above (ADHD, schizophrenia, or autism) and research the data on how prenatal stress may be linked to the development of this disorder in the womb. Also, address the following questions below:

How strong does the data support maternal stress and the development of your chosen disorder?

Why do you think some children seem to be affected by prenatal stress and not others?

When responding to classmates, consider the influence of other factors that may play a role for both the mother and fetus.
