This is an important philosophical issue. There are 4 Ds in whether something is diagnosed or considered a dsiorder:

  1. Deviance: Varying from the norm, the average of society. This is useful in come situation, like diagnosing memory decline in possible Alzheimer's disease. However, by itself it can overemphasize conformity, which is a problem.
  2. Distress - Is what the person,s experiencing creating some kind of distress or suffering. People used to think of schizophrenia as a “sane response to an insane world”, but really they are suffering horribly as a result of this.
  3. Dysfunction - Does it interfere with a person's ability to get through their day, support themselves, accomplish the things they would like to accomplish.
  4. Dangerousness - This is more of a consideration in forensic settings

ADHD is a spectrum on which we all fall, but the extreme cases that are diagnosed meet the distress and dysfunction criteria.

There are two aspects to his statement:

  1. ASD/ADHD are neurodevelopmental rather than mental health issues. Substantively provable

  2. ASD/ADHD is mostly genetic. I agree with you that we're not yet in a position to discard all environment factors.

Using the term "mental health" isn't appropriate in this context. General treatments for mental health conditions (CBT, antidepressants etc) have almost no overlap with treatments for neurodevelopmental disorders, unless there is a comorbidity that leads to separate mental health issues.

Assuming it was an unopened can, freezing it could cause the can to 'explode' . You see it happen with drink cans a lot because of the thinner material and the carbonation in lots of drinks but it can happen with any sealed liquids without room to expand.

https://youtu.be/t5mdZD00POs this guy demonstrates it by freezing a sealed pipe with liquid nitrogen to spread up the process

It wouldn't be as airtight of an experiment to show causality, especially since again no evidence points to vitamin deficits being a direct mechanism. You'd probably have to track prenatal health, and you'd have to measure known genetic ADHD markers to account for ADHD being highly genetic when running statistical analyses.

But good luck getting the cash to fund it if there isn't already compelling evidence that vitamin deficit is directly linked to ADHD. Investors usually don't like "taking risks for the sake of exploration" unfortunately
