Just a brief little piece on the possibility of a pregnant woman who is depressed at the time in some way passing on wiring abnormalities in the Amygdala,
in their child. This is a structure in the brain that possibly links to depression. One sentence I found particularly dispiriting.

"This finding suggests a history of maternal depression might contribute to a lifelong increase in the vulnerability to mental illness."

So screen pregnant women and treat those who are depressed. I don't see that happening.

Here is the link. It is long and I'm not sure it will work. You'll find it on Google if you want to read.

Sometimes the light is shining on me
Other times I can barely see
Lately it occurs to me
What a long, strange, trip it's been

Couldn't persuade link to work so here is the press interview.

Maternal Depression May Affect Infant Development

Maternal Depression May Affect Infant Development New research finds that depression among pregnant women may have an impact on their developing babies.

Experts have observed that children of depressed parents are at an increased risk of developing depression themselves — presumably a combination of both genetic and environmental factors.

These children also display alterations in the amygdala, a brain structure important for the regulation of emotion and stress.

Previous research has focused on children many years after their birth, leaving unanswered questions on the genetic association.

A new study by Dr. Anqi Qiu and colleagues at the National University of Singapore, published in the journal Biological Psychiatry, provides answers on the effect of prenatal depression.

Researchers set out to perform a direct analysis of prenatal maternal depression and variation in the fetal development of the brain region called the
amygdala, an area associated with memory formation and emotions.

To do so, they recruited 157 pregnant women who completed a depression questionnaire during their 26th week of pregnancy.

Later, within two weeks of birth, newborns underwent magnetic resonance imaging scans to ascertain the structure of their amygdala and diffusion tensor imaging scans to determine the integrity of the amygdala’s pattern of neural connections.

The volume of the amygdala did not differ between the infants regardless of their mothers’ depression status. But researchers found that the amygdala’s microstructure (e.g., its “wiring”) was abnormal in the infants born to depressed mothers.

This important finding suggests that a propensity for abnormal amygdala function, a feature of mood and anxiety disorders, may be transmitted from mother to child during fetal life.

This finding suggests a history of maternal depression might contribute to a lifelong increase in the vulnerability to mental illness.

Researchers believe this study provides added evidence supporting the notion that mental health screening should be included among the medical evaluations that women undergo when they discover that they are pregnant.

Indeed, the authors conclude that “interventions targeting maternal depression should begin early in pregnancy.”

“Attention to maternal health during pregnancy is an extremely high priority for society for many reasons,” added Dr. John Krystal, Editor of Biological
Psychiatry.

“The notion that maternal depression might influence the brain development of their babies is very concerning.

“The good news is that this risk might be reduced by systematic screening of pregnant women for depression and initiating effective treatment.”
