Thanks to medical advances in the past 20 years, neurosurgeons now have the ability to tackle tumours, save traffic accident victims, stop epileptic seizures, control Parkinson's tremors and even treat depression. Not only are they able to deal with life-threatening disease or trauma, they can be intimately and powerfully involved in the quality of life of their patients. And new advances are being made all the time. Of the 30 specialist neuroscience centres in the UK, the Walton Centre in Liverpool is at the forefront, both in terms of its highly experienced staff and cutting-edge technology. It is the only NHS Neuroscience Trust in the UK and treats more people with brain problems than anywhere else in the country. For this series, the Walton Centre has granted full access to their staff and facilities. The series follows some of its most impressive, groundbreaking surgical stories through the stories of the patients, each of whom suffers from a different neurological condition.
