Autism is where marketing pressure on families is heaviest. This framework is written to help you say no as easily as yes.

The short answer

Published human studies in autism are small, heterogeneous and mostly uncontrolled, and the outcome scales used are subjective. Some randomised work exists and reports modest changes in behavioural scales, with no evidence that core autism is cured. We only discuss treatment alongside continuing behavioural and educational therapy, never instead of it.

Who this decision applies to

Usually appropriate to discuss

  • Formal diagnosis by a paediatric neurologist or developmental paediatrician
  • Established behavioural, speech and educational therapy already in place
  • Parents who understand the outcome measures are subjective and the evidence is early
  • Capacity to attend structured, dated follow-up assessments

Not appropriate right now

  • Families told to pause established therapies during treatment
  • Children with unexplained regression that has not been fully investigated
  • Expectation of a cure, or of speech appearing on a promised timetable
  • Any protocol involving unlicensed products or undisclosed cell sources

Evidence at a glance

The same five questions we ask of every indication, answered for this one.

Evidence maturity for Autism: a family decision framework
QuestionAnswerWhat that means here
Human studies published?YesHuman studies including some randomised trials have been published.
Randomised controlled trials?LimitedRandomised trials exist but are few, small and inconsistent in design.
Objective outcome measures?PartlyCARS, ATEC and ABC scales are used; all rely on observer judgement.
Long-term follow-up (≥12 months)?LimitedLong-term developmental follow-up is largely absent.
Approved as a routine therapy?NoNo regulatory approval for cell therapy in autism in any major jurisdiction.

Options compared, including doing nothing

Realistic options for Autism: a family decision framework
OptionWhat it can realistically doMain trade-off
Intensive behavioural and speech therapyThe best-evidenced intervention for developmental progressTime-intensive and expensive over years
Medical management of comorbiditiesSleep, seizures and GI problems often improve function mostDoes not address core features
Cell therapy as an adjunctUnder study; reported changes are modest and variableCost, travel and no guarantee of any change
Wait and reassessAvoids exposing a child to an unproven interventionFamilies often find waiting hardest

How the decision is made in practice

  1. We ask for the diagnostic report, current therapy schedule and any recent scale scores.
  2. We check that comorbidities such as epilepsy, sleep disorder and GI disease have been addressed first.
  3. We ask parents to describe the change they are hoping for, and we say plainly whether it is realistic.
  4. Baseline scales are recorded before treatment and repeated by the same assessor afterwards.
  5. Behavioural and educational therapy continues throughout; that is a condition of treatment.

When we decline, and why

  • Where established therapies have not been tried or would be paused
  • Where a cure is expected, or the family cannot accept a null result
  • Unstable epilepsy or other uncontrolled medical conditions
  • Regression that has not been neurologically investigated

Declining is a normal outcome of assessment, not a failure of it. See how candidacy and redirection work.

Questions worth asking any clinic

  • Which scales will be used, who administers them, and are they the same person before and after?
  • What did the randomised trials in autism actually report, and over what period?
  • What is the source, dose and release testing of the cells?
  • What will you tell me if nothing changes?

Frequently asked questions

No. There is no published evidence of cure, and any clinic implying otherwise is misrepresenting the literature. Published trials report modest, variable changes on behavioural scales in some children and no change in others.

We cannot promise that, and we do not. Speech development in young children continues with therapy regardless of any intervention, which is exactly why uncontrolled reports are so unreliable in this indication.

No, and we would decline to treat if that were the plan. Established therapy is the intervention with real evidence behind it; nothing we do should interrupt it.
