Autism symptoms reversed in lab

‘Symptoms of mental retardation and autism have been reversed for the first time in laboratory mice.

US scientists created mice that showed symptoms of Fragile X Syndrome – a leading cause of mental retardation and autism in humans.

They then reversed symptoms of the condition by inhibiting the action of an enzyme in the brain. [..]

Researcher Dr Susumu Tonegawa stressed that the mice were not treated until a few weeks after symptoms of disease first appeared.

“This implies that future treatment may still be effective even after symptoms are already pronounced,” he said.’
