The recent case of Lindsay Clancy — the mother in the US facing at least two counts of murder in the deaths of her three children — has weighed heavily on my heart over the past several days.

According to her husband, she was a young mother struggling with postpartum depression and psychosis, and receiving treatment in an intensive outpatient program.

She allegedly took her children’s lives and then tried to end her own.

The DSM-5-TR nomenclature for this condition is peripartum onset, referring to mood onset during pregnancy or within four weeks of delivery.
