People with ADHD tend to have lower omega-3 in their blood, and bringing low levels up has been linked with some improvement in symptoms. No convincing difference has shown up between DHA and EPA for this.

Omega-3 comes mostly from oily fish and krill, and fish is exactly what many people with texture sensitivity will not eat. Whether the shortfall…

If you are trying omega supplements, give them four to six weeks and then decide. Imaging work has picked up changes in how neurons communicate after around four weeks, which is fast as these things go.

Fixing the end point at the start protects you twice over. It takes the sting out of nothing happening by Thursday, and it stops an open ended habit…

In one trial, children were given omegas with a multivitamin, omegas alone, or neither, and after fifteen weeks everybody got both. The omega groups gained on set shifting and attention, and the children who started with nothing caught up once they crossed over.

Two features of that design are worth understanding. Everyone receiving the treatment eventually shows that the improvement follows the treatment…

Sixty two children took methylphenidate with either vitamin D or a placebo, and both groups improved. The two ADHD rating scales showed no difference between them, which leaves the positive headline resting on the clinician's judgement rather than on what parents reported.

That shape repeats all over this literature, so it is worth learning to spot. When a study reports an effect on one measure and not another, the…

People with ADHD are reported to run low on both tryptophan and homocysteine. Low homocysteine is a good thing to have, since it is the high version that damages hearts.

The reflex to correct any number under the reference range is worth resisting. Levels can be tested where there is a reason to test them. Eating a…

Omega supplementation for ADHD began with encouraging results, including a Swedish study where about a quarter of inattentive children seemed to improve. Blinded, placebo controlled work did not reproduce it, and a Cochrane meta-analysis found no effect.

The manufacturers themselves largely moved on to other conditions, which tells you something. None of this makes omegas worthless, and levels do run…

Cutting sugar does not improve ADHD, and nor does stripping out additives. Both have been tested repeatedly, including under conditions where nobody knew which child had eaten what.

The belief survives because parties are where children eat sweets, and parties are also loud, crowded and thrilling. The sugar takes the blame for…

Megavitamins, antioxidant products such as pycnogenol and assorted trace minerals have not beaten placebo for ADHD. They stay popular on the strength of a good story about how they ought to work.

The gap between a mechanism and an outcome is the thing worth teaching, because it will still be useful when the next product appears. Ask what…

Chiropractic neurologic organisation training, the kind involving manipulation of the skull, has no credible theory behind it for ADHD. The main harm is not the treatment itself but the months and the money that go into it.

Families meet this because it is marketed at them at the exact moment they are most willing to try anything. Naming it plainly, once, is usually…

With EEG neurofeedback, the weaker the study, the better the results look. Six large trials using sham feedback, with parents and teachers kept unaware of who received what, found nothing beyond placebo.

That shrinking with rigour is itself the finding. Blinding matters especially here because the outcome is a rating made by adults who have watched…

Brain training makes you better at the game, and at things that resemble the game. It does not seem to reach the parts of life you bought it for.

Cogmed, the several hundred apps, the balance based programmes: they all hit the same wall when someone independent tests them with a proper control…

One senior researcher in this field is approached by ADHD app startups roughly once a month and no longer takes part, on the view that the companies are not seriously trying to build something that works.

You do not have to share his judgement to borrow the question. Before paying for a digital product, ask who tested it, whether those testers were…

If you are going to take supplements, it is worth paying a small subscription to a service that assays what is actually in them. ConsumerLab is one, at roughly sixty dollars a year.

The thing to check about any such service is who funds it, because a tester paid by manufacturers is a marketing department with a laboratory…

When omega levels are low, everything about ADHD tends to get louder: attention, mood swings, holding things in mind. Low omega does not cause ADHD, but it can be sitting on top of it.

Think of it as one more layer to lift off rather than the thing underneath. Specialist labs can measure levels if it seems worth checking, and…

One woman's ADHD symptoms climbed and her thinking slowed as each B12 injection wore off, then settled again after the next one. The deficiency came down one side of her family and the ADHD down the other.

The two lived in the same person without either causing the other. What made it findable was the timing, because difficulties that follow a cycle are…

Play therapy and insight based psychotherapy do not treat ADHD. There is no buried, unexpressed feeling driving it that talking will let out.

The difficulty sits in executive control and how it develops, not in hidden conflict. That said, a child with ADHD can also be anxious, grieving or…
