It's an article with no clear conclusion it's normal to feel confused.

My read of the article is balancing the fact that there's a lot of overlap between CPTSD/ADHD/ASD in the symptoms (emotional dysregulation, hyperarousal, etc) and in hereditary factors (undiagnosed parents causing trauma more often on average). Also that traumatic childhood experiences are more likely to stick around as CPTSD in adulthood if there's also neurodivergence.

The author says there can be incredible relief to be correctly diagnosed with ADHD/ASD, so obviously she says it's helpful.

But she also warns that wrong treatment can often happen (eg. Giving stimulants to perpetual fight or flight PTSD brains), or inneffective therapy.

Through a quick read I understood...

- People with ADHD and Autism have higher probabilities of childhood trauma and abuse. They might seek a diagnose in adulthood and that can bring them relief and be helpful.

- People with non-ADHD/autism related childhood trauma are more likely to perceive themselves as being neuro divergent. They might have executive disfunctions, and try to find an ADHD diagnosis (that could probably get, as it matches their symptoms) but as of today seems like there isn't evidence (yet) that ADHD stimulant medication helps with non-ADHD executive disfunctions.

- Hence, is important for professionals to verify the history of the patient and make sure they had ADHD symptoms when they were children (that would confirm ADHD), and if not, maybe try to find different psychotherapeutic treatments that would be more helpful to their complex PTSD.

I think it says that psychologists/psychiatrists do not really know what to do when adhd/autism symptoms overlap with childhood-rooted complex ptsd/trauma in adult patients and more research is needed. That's how I read it mostly.
