"This research is one of the first clinical trials to assess whether a drug can improve brain function in people with an inherited disorder.
"The potential benefits of this treatment include an improved quality of life for affected patients and wider benefits for their families and carers.
"If it works it will benefit patients directly and could provide clues as to whether this class of drugs (called mTOR inhibitors) might have wider benefits in problems like autism."
A trial is underway at Cardiff University to see whether a drug to combat Tuberous Sclerosis could also treat autism. The trial is being co-ordinated by the South East Wales Trials Unit, in the School of Medicine at Cardiff University.
