New study links size of baby's head to autism

A new study linking autism to very rapid brain growth in

babies will boost the pro-MMR campaign.

Researchers at the Univer-sity of California found sudden and excessive growth of infants' brains in the first 14 months of life was a precursor of autism. They concluded the MMR vaccine was not a 'logically plausible' cause of autism.

The study, published earlier this month in the Journal of the American Medical Association, looked at the records of 48 children with autism aged two to five. They found many were born with unusually small heads and then showed accelerated increase in brain volume and head circumference between one and two months and six to 14 months.

Researchers concluded this interfered with neurological development in the period before behavioural expressions of autism are detected.

Excessive head size has been linked with autism previously.
