A 2025 systematic review of 20 antioxidant trials in autism found the L-carnosine studies contradictory and at high risk of bias, with no solid evidence of clinical benefit. The individual randomised trials mostly missed their main targets: no change in autism severity or irritability, with scattered improvements in single areas such as sleep quality or hyperactivity that no second trial has confirmed.
There are no published clinical trials of Autinorm in autistic children — none. The evidence its marketing gestures at belongs to leucovorin (folinic acid), a prescription medicine, and a major review states plainly that folinic acid is the only form of folate used to treat cerebral folate deficiency apart from a single case report. Autinorm contains methylfolate instead, at a dose far below what those studies used, and paediatric bodies say even leucovorin is not standard care for autism.
Professional guidelines from AOTA, APTA and ASHA, along with hospital discharge policies, converge on three main reasons to end pediatric therapy: goals are met, therapy is no longer producing functional change, or the family decides to conclude care. Guidelines also describe stepping down to less frequent or consultative therapy rather than stopping outright, and treat therapy as something a child may return to at later stages. None of this comes from controlled trials of when to stop.
Somewhere between 40% and 80% of autistic children have significant sleep problems — several times the rate in other children — and part of the reason is biological, not behavioural: the body clock and melatonin signal often work differently. The good news is that this is one of the more treatable things in autism. Guidelines agree on the order: fix the routine and the bedroom first, and add melatonin only if that is not enough.
Parents are often told to start occupational therapy before ABA, or the other way round, but no study has actually tested one order against the other. The strongest recent evidence is a randomised trial that ran the two therapies separately and found both improved children's daily living skills and personal goals, which suggests the order matters far less than whether the therapies are coordinated and matched to your child's most pressing needs.
Sugar does not cause autism or ADHD, and the famous 'sugar makes kids hyperactive' belief has been repeatedly debunked. But the picture is more nuanced than a simple yes or no — high sugar intake, particularly from sweetened drinks, is associated with worse emotional regulation, executive function, and behaviour in autistic and ADHD children. The gut-brain axis may be the key mechanism.
Autism does not have a single cause. It emerges from a complex interaction between genetic predisposition and environmental influences — mostly acting before birth. Genetics is the dominant driver, accounting for roughly half of the risk, but prenatal exposures, parental age, birth complications, and environmental toxins each contribute. None of these factors act in isolation.
Research consistently identifies five skill areas that have the greatest downstream impact for autistic children: communication, social skills, emotional regulation, play, and daily living independence. Evidence from multiple meta-analyses shows that early, targeted support in these areas — especially when caregivers are actively involved — leads to meaningful improvements across the board.
