Crohn's disease 1

Another rare neurological side effect of Crohn’s is the potential to develop cranial neuropathy, causing headaches, vision problems and other brain related issues. Researchers are unsure how Crohn’s leads to cranial neuropathy, but it could be due to the anti- TNF therapies causing brain lesions. It has brought up the debate of changing the recommended treatment if you develop any symptoms of cranial neuropathy.  New recent studies also seem to show that neurological symptoms are more common than originally thought, increasing the severity of this disease.
