While I was away on vacation, I missed two more tragic stories in the news, one in Canada and one in Denver. I hate these storie — hate them — because they are just so preventable.

Before you read on, if you are vulnerable or suffering right now, don’t read on. It’s not necessary. Trust me.

In the Canadian case, fortunately the mother who attempted murder was not successful. Two things stand out to me about her story. One is that she lived in inner-city public housing, and we know that poverty is a risk factor for perinatal mental illness. The second is that she had only recently immigrated to Canada from Africa, and we know that being away from your familyand culture is also a risk factor. I hope she gets the help she needs.

In the Denver case, what stands out to me is that the mother who committed infanticide was a mental health counselor. People might besurprised by that fact, but I’m not.Doctors and clinicians are not immune to these illnesses, and we know that women suffering from perinatal mood and anxiety disorders often don’t recognize what’s happening to them, even those who are trained healthcare professionals.

In a recent in-depth story on AOL Health about the Melanie Blocker Stokes MOTHERS Act, Dr. Delia Aldridge, service director of the Eating Disorder, Self Injury Recovery, and Women’s Programs at Alexian Brothers Behavioral Health Hospital, shares one reason why these women slip through the cracks.

“[Postpartum mood disorders] often go unrecognized,” says Aldridge. “In medical school, you do six weeks of psychiatryclerkship, and you don’t learn much about postpartum depression.”

I hope one day that changes.
