An experimental autism therapy being trialed in Manchester that helps parents communicate with their children has had a record level of success in reducing core symptoms of the condition.

A trial involving daily 20- to 30-minute sessions of planned communication and play activities showed benefits that lasted six years after the treatment ended.

It is the first time long-term effects of such an early intervention have been demonstrated.

The follow-up study was designed to look at long-term outcomes from the Pre-school Autism Communication Trial (Pact), which involved 152 autistic children aged two to four.

In the new analysis, 121 or the original participants were re-assessed after six years. Of these, 59 had received the Pact therapy.

Symptoms in the treated children were found to be less severe, with improvements in social communication and a reduction in repetitive behaviour.

Although no changes were seen in other areas such as language, anxiety and challenging conduct, experts regarded the results as highly significant.

Autism is a "spectrum" developmental disorder affecting about one in 100 people and causes symptoms that vary greatly in severity.Core symptoms include an impaired ability to communicate and engage socially, and obsessive or repetitive behaviour.

The Pact intervention focused on parents who were invited to watch videos of themselves interacting with their children and receiving feedback from therapists.

This had the effect of enhancing parents' awareness of their child's unusual patterns of communication and helped them to respond appropriately.

Parents took part in 12 therapy sessions over six months, followed by regular support over another six months.

In addition, parents agreed to spend 20 to 30 minutes each day engaged in planned communication and play activities with their children.

Autism severity was given a score of one to 10 according to a standard international method of combining social communication and behaviour symptoms.

The findings, published in The Lancet medical journal, showed a 17% reduction in the proportion of children from the intervention group with severe symptoms.
