Hi Stuart,
That is NOT true!! You can definitely have MS without lesions in the brain. The central nervous system includes the brain, the spinal cord, and the optic nerves. Damage in any of these areas can be caused by MS.
I have MS. My visible lesions are in my cervical spine and I've had optic neuritis several times. The MRI scans I've had do not show lesions in my brain. Evoked potential testing and a spinal tap contributed to my diagnosis.
A neurologist who specializes in MS would be best able to make an accurate diagnosis.
