A natural substance found in broccoli could offer an unexpected new approach to treating a devastating genetic disease that progressively damages the nervous system. Researchers at Swinburne University have identified promising effects from the compound, raising hopes for a more affordable and accessible treatment for patients with few available options.

The disease, known as Friedreich ataxia, causes nerve cells in the brain and spinal cord to gradually deteriorate. As the damage progresses, patients lose their ability to coordinate movements, walk, and speak. The condition can also shorten life expectancy, and there is currently no cure. Approximately 200 Australians are living with the disease.

In a new study, scientists found that sulforaphane, a naturally occurring compound in broccoli, can increase levels of frataxin, a protein that is present in insufficient amounts in people with Friedreich ataxia.…
