This was tested in people. That is the most reliable kind of research we share.
This is a report on two patients seen by doctors, not a treatment being tested.
The short version
Doctors describe two people who had both NF1 and multiple sclerosis, and explain why the two are easy to confuse.
What was studied. This is a report on two patients. One was a 33-year-old woman and the other was a 49-year-old man. Both had neurofibromatosis type 1 (NF1), a genetic condition that can cause growths on nerves, including on the nerves of the eye. Both were also found to have multiple sclerosis (MS), a condition that damages the coating around nerves.
What they found. Having both conditions is rare. About 40 cases have been reported by doctors so far. In the first patient, MS was found first, and signs of NF1 were spotted afterward. In the second patient, NF1 was known first, and MS was found later during routine check-ups. Brain and spine scans plus careful eye exams were what told the two conditions apart.
What this means, and what it doesn't
What it could mean: If you have NF1 and get new symptoms, they may not always be coming from NF1. Vision changes and bladder or feeling problems can have another cause. Careful scans and eye exams can help sort out what is going on, so you get the right care.
What it doesn't mean: This is not a treatment and it is not a cure for either condition. It is a report on two patients, not a study that tested anything. Two patients cannot tell us how often this happens or what to do about it. The doctors also point out there are no agreed treatment guidelines when NF1 and MS happen together.
