Spinal cord lesions are more commonly seen in progressive forms of multiple sclerosis, and they can result in an increased risk of disability.

Nearly everyone with multiple sclerosis (MS) has signs of lesions in the brain, as shown by magnetic resonance imaging (MRI) scans, according to Anthony Reder, MD, a multiple sclerosis specialist and professor of neurology at the University of Chicago.

But the brain isn’t the only area where lesions can develop — MS can also attack the spinal cord. Because finding these lesions involves more elaborate imaging tests, spinal cord lesions in MS are studied less often, and many people with MS aren’t aware of the role these lesions may play in the disease process.

Researchers, too, have knowledge gaps about this feature of the disease, but one thing that seems clear is that filling these gaps may lead to a better understanding of progressive forms of multiple sclerosis.
