Consider four patients, Alice, Bob, Carol, and Dan. Alice has poor concentration caused by child abuse. Bob has poor concentration caused by bad genes. Carol throws tantrums because child abuse. Dan throws tantrums because bad genes. The current DSM would categorize Alice and Bob as ADHD, and Carol and Dan as intermittent explosive disorder. Van der Kolk would like to classify Alice and Carol as having Developmental Trauma Disorder, and Bob and Dan as…I don’t know. Bad Gene Disorder? Seems sketchy. When the APA decides not to do that, they’re not necessarily rejecting the seriousness of child abuse, only saying it’s not the kind of thing they build their categories around.
