My 45-year old friend suffered hypoxia and multiple strokes due to arterial dissection. When she came to (3 days after admission to ICU) she had reasonable capabilities - talking, trying to stand, tracking with eyes, voluntary movement of left side of body, follow commands. Six days later she suddenly lost these capabilities and for the last week has only been able to open her eyes, cry or laugh. But she has not been able to follow commands, track with eyes, voluntarily move or talk. CT scan showed hydrocephalus concurrent with loss of capability so a ventric drain was inserted to relieve swelling in brain. But she has not regained any capability. HELP! What else should we check for? Only med that changed during the regression was coumadin but the INR levels do not correlate with the regression. Please help! Thank you so much
