The difference between coma and brain death is that patients can recover from coma. They can't recover from brain death. Kind of like the difference between having a cold, and being Welsh.

Medical Emergency - New Onset Coma is an immediate reason to worry, start crying, and perhaps call a real doctor!

Diagnosis
