I agree with Dr Christy. There are definitely distinguishing features but also some overlap features. With a good history, exam, labs & imaging from onset and comparing to 6 months later, most of the time you'd be able to determine the most likely diagnosis

Marks was also instrumental in bringing together Operation Warp Speed that enabled COVID vaccines to be produced <1 yr after the pandemic. These vaccines saved millions of lives worldwide. He was forced out of his longstanding role spanning three administrations because of RFK.

This leap forward has changed neurology & all of healthcare. If it wasn't for the SMA gene therapy trials and Dr Mark's approval, we would not be developing gene therapies for hundreds of diseases now. The next breakthrough could be for a disease that affects someone you love. 2/
