Gluten can cause brain lesions like ALS
Here is another alarming paper published in the American Journal of Neuroradiology reporting a case of apparent Amyotrophic Lateral Sclerosis (ALS, also known as Lou-Gehrig's Disease) that was caused by a reaction to gluten. ALS is a particularly vicious autoimmune disease that attacks the central nervous system, typically following a terminal course. The authors note regarding celiac disease that "Initial symptom presentation is variable and can include neurologic manifestations that may comprise ataxia, neuropathy, dizziness, epilepsy, and cortical calcifications rather than gastrointestinal-hindering diagnosis and management." I'm sure they were relieved to find that "MR imaging findings suggestive of ALS improved after gluten-free diet institution." (MR = magnetic resonance)
