The Claim
Methimazole therapy initiated in a woman with Graves' disease was followed by the development of central nervous system vasculitis, which resolved within five weeks after drug discontinuation, with normalization of brain MRI and SPECT findings observed six months later.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
A woman with Graves' disease developed inflammation of blood vessels in the brain after starting methimazole; this condition improved after stopping the drug, and brain imaging returned to normal six months later.
See the scientific wording
Central nervous system vasculitis developed in a woman with Graves' disease shortly after initiating methimazole therapy, and resolved within five weeks after discontinuation of the drug, with normalization of brain MRI and SPECT findings six months later.
Methimazole changes the shape of thyroid proteins so the immune system sees them as foreign, triggering immune cells to attack blood vessels in the brain, causing inflammation that clears when the drug is stopped.
What the research says
1 studyStudy: Central Nervous System Vasculitis after Starting Methimazole in a Woman with Graves' Disease
A woman with an overactive thyroid started taking methimazole and then got brain inflammation. When she stopped the medicine, her brain got better and scans returned to normal within six months. This suggests the drug might have caused the problem.
