Babies' brains 'show autism risk'

It may be possible to detect autism at a much earlier age than previously thought, according to an international team of researchers.

A study published in Current Biology identified differences in infants' brainwaves from as early as six months.

Behavioural symptoms of autism typically develop between a child's first and second birthdays.

Autism charities said identifying the disorder at an earlier stage could help with treatment.
