On a video call in early September, Sarah Tabrizi first saw the data that she and other researchers studying Huntington’s disease had been chasing for decades: compelling evidence that a gene-targeting therapy could slow the relentless progression of the neurodegenerative brain disorder.

Before these results, “I was beginning to get a little bit worried that maybe, by the time people develop symptoms, that it was going to be too late to treat”, says Tabrizi, a neurologist who directs the Huntington’s Disease Centre at University College London.
