ADEM can set in within days or even weeks following a vaccination. 

 

Typical symptoms at the onset of ADEM include headache, fever, weakness, and nausea.  Over time, ADEM sufferers can develop loss of coordination and motor deficits, slurred speech, and loss of feeling in affected areas of the body.  Severe cases can even result in coma.
