Beyond blue: new hopes arise in magnetic fields

A PIONEERING treatment using magnetic fields to stimulate brain activity has helped people with depression live medication-free and is now being trialled on autistic young people, patients with bipolar disorder and those with traumatic brain injuries.

Doctors at The Alfred hospital say transcranial magnetic stimulation (TMS) has a high success rate, with fewer side effects than more invasive treatments such as electric shock therapy.

Patients are fully conscious and do not need hospital admission. Some are even having the 40-minute sessions in their lunch break. A course of treatment is typically five sessions a week for four weeks.

Magnetic pulses applied to a coil on the patient's head deliver a gentle electric current that fires up nerve cells in the brain.

While previously the procedure was tested for use in combating depression and schizophrenia, The Alfred is now trialling ''deep TMS'' for disorders such as autism and Asperger's in patients as young as 18. The therapy uses a coil that stimulates an area of the brain which controls social functioning.

Paul Fitzgerald, deputy director of the Monash Alfred Psychiatry Research Centre, said the treatment had been able to change the way people with the disorders related to others by helping them better read body language and verbal cues.

''We're looking at trying to improve their capacity for social decision-making, their capacity to judge other people's individual emotional state so they can make better judgments in social settings, which is one of the core problems for people with autism,'' Professor Fitzgerald said.

''If you look at brain imaging studies of patients with autism, if they're required to do tasks that involve making social judgments, particular networks in their brain are just not as active as they should be.''

Patients with bipolar disorder and those suffering severe depression after head injuries sustained in road accidents are also seeing results in as little as four weeks.

Another trial is looking at using the technology to help people beat addiction to drugs or alcohol.

Most patients with depression who have had the treatment found it lessened their symptoms and improved appetite and sleep patterns.

Professor Fitzgerald said the therapy had become a mainstream mental health procedure in the United States with up to 250 centres offering it as a standard clinical treatment. ...
