An other name for Chiari malformation is: cerebellar tonsillar ectopia
Hi,
You should get and MRI done of your brain and cervicals! I am aspie and have had been having the worst headache for many years now, and I finelly convince my MD to get me one and they found that I suffer a Chiari Malformation. It's commonly found in people with asperger (that's wath I found on the web). And that's what gives me my headache. So just to by on the safe side you should get check.
Hope you feel better,
Drew
