I read a book once decades ago about ADHD, and it said lots of children are misdiagnosed with it. One of the very common causes is that kids who don't eat regularly (or eat sugar then crash) will encounter low blood sugar. The body reacts to this by dumping adrenaline in the bloodstream and ... voila ... an excitable kid with little focus.

It's both under- and over-diagnosed because the funnel for children is teachers who have basically been trained to refer the "problem children" for diagnosis.

I have a son who has extreme anxiety, and kept getting referred by teachers for ADHD. Hyper-vigilance for danger can make it hard to focus on arithmetic, particularly in an elementary school classroom. The psychiatrist ended up putting a note in his file because this was happening.

Meanwhile, I also have a daughter who is so obviously ADHD: she forgets to turn in her homework; there were 6 of her jackets in the lost and found in October; she will go to school without her eyeglasses; &c. But, she doesn't disrupt the classroom and is otherwise seen as a "good kid" so she was never referred by a teacher.

  • I used to be your daughter! Super quiet, got all my work done on time, was seen as "gifted", but would lose absolutely everything (and I mean everything).

    I really suggest some sort of setup to maintain structure as she gets older - being aware of a diagnosis or having medication / therapy would've really saved a couple painful years in university for me

Between decades ago and now we've recognized that sugar only causes excitableness in children who are prompted (Clever Hans style) by adults who expect such an outcome.

The wisdom you're referencing is circa the 70's, it's been attempted many times since and has never replicated.

  • The comment you're replying to doesn't seem to mention the debunked "sugar rush". The "crash" on the other hand seems to be more replicable.

    Also your framing ignores that the "prompting" can be circumstantial rather than targeted. The "rush" is frequently misattributed to sugar when it can actually be better explained by the food itself being a rare treat (and thus exciting) or the situation in which it is provided being special (e.g. a party). Or it can simply be the joy of eating something very tasty.

    It's less Clever Hans and more "kids are more prone to sudden outbursts of strong emotions and adults blame it on food".
