Positron emission tomography (PET scanning) was used to study seven adults with Tourette's syndrome. It showed an increased rate of presynaptic release of dopamine from the striatum (American Journal of Psychiatry2002;159:1329-36).

Determine the cause, says a report in Archives of Disease in Childhood (2002;87:202-6). If no diagnosis is made, parents may suspect measles and confidence in the vaccine will be eroded.
