In a Stroke Patient, Doctor Sees Power of Brain to Recover
When a person suffers from a stroke, usually the blood supply to part of their brain is abruptly disrupted and as a consequence brain cells die due to the lack of oxygen and nutrients.

Words such as coma, vegetative state, brain death or cortical death — terms holding similar connotations yet different definitions — can leave both the families and the doctors with a controversial decision to be made.
