Can my stutter be cured?

Most of us take the ability to speak fluently for granted, but for listener Breeda it has been a lifelong struggle. She has asked CrowdScience to investigate whether there is a cure for stuttering and, if not, what the best way to live with it is. Breeda is not alone, as stammering is a neurological condition that affects 70 million people worldwide. The CrowdScience team head to Oslo in Norway to follow a group of young people who have signed up for a highly disciplined and potentially life-changing training course. The first milestone is to learn to say their name without a stutter. For many, this is a huge challenge that triggers years of distress and anxiety. With hundreds of muscles and many parts of the brain being involved, speaking is one of the most complex tasks that humans perform. Scientists have discovered subtle differences in the insulation surrounding nerve cells, so-called myelin, between people who stutter and those who don’t. This irregularity may be the source of a tiny time delay in signals between crucial regions of the brain that need to work closely together to produce speech. In the future, it may be possible to stimulate certain brain areas to boost growth and connectivity.
