Scientists found that taking the drug just once or twice by the age of 14 led to greater “grey matter” volume in key brain areas linked to emotion and memory.
Grey matter mostly consists of nerve cells, while “white matter” is made up of nerve fibres.
The effects of the changes are unknown. But boosting nerve cell numbers may not be as beneficial as it sounds in developing brains, the US researchers point out.
At about the age of 14, the adolescent brain undergoes a form of “pruning” which removes unwanted neural connections, allowing the most important ones to be strengthened.
