Updates to Mc Donald Criteria
Getting a clear and timely diagnosis of multiple sclerosis (MS) can make a big difference to care, treatment, and peace of mind. To guide this process, doctors around the world use the McDonald criteria – a set of internationally agreed rules first introduced in 2001 and regularly updated as science advances.
In 2024, these criteria were revised again by an international panel of experts, including clinicians, researchers and patient representatives. The goal was to make MS diagnosis more accurate, less invasive, and more accessible worldwide.
