Proton magnetic resonance spectroscopy and MRI reveal no evidence for brain mitochondrial dysfunction in children with autism spectrum disorder.
Brain scans show normal energy chemistry in autism, so drop mitochondrial hype and focus on skill-building instead.
01Research in Context
What this study did
The team scanned the kids. Half had autism. Half had typical development. All were 8-11 years old.
They used two machines. MRI showed brain shape. MRS checked energy chemicals inside cells. They looked for weak mitochondria.
What they found
Energy markers were the same in both groups. No sign of broken mitochondria. MRI looked normal too.
The data say autism is not a “mitochondrial disease.”
How this fits with other research
Stanford et al. (2026) tell a different story. Gut germs make three chemicals that rise in autism. Animal pups fed these chemicals act autistic.
The papers seem to clash. Griffith et al. (2012) find clean brain chemistry. Laura’s team finds messy gut chemistry. The gap is location: brain vs. intestine. Gut bugs can bother the brain without hurting mitochondria.
Zadok et al. (2024) add another null. Autonomic nerves react the same in autistic and typical kids during social tasks. Together the studies shrink the list of “broken brain parts” we can blame.
Why it matters
You can stop selling parents on mitochondrial cocktails and hyperbaric oxygen. Brain scans give no fuel for that story. Shift time to teaching skills and shaping environments where kids can use the energy they already have.

03Original abstract
Brain mitochondrial dysfunction has been proposed as an etiologic factor in autism spectrum disorder (ASD). Proton magnetic resonance spectroscopic imaging ((1)HMRS) and MRI were used to assess for evidence of brain mitochondrial dysfunction in longitudinal samples of children with ASD or developmental delay (DD), and cross-sectionally in typically developing (TD) children at 3-4, 6-7 and 9-10 years-of-age. A total of 239 studies from 130 unique participants (54ASD, 22DD, 54TD) were acquired. (1)HMRS and MRI revealed no evidence for brain mitochondrial dysfunction in the children with ASD. Findings do not support a substantive role for brain mitochondrial abnormalities in the etiology or symptom expression of ASD, nor the widespread use of hyperbaric oxygen treatment that has been advocated on the basis of this proposed relationship.
