When will my grandmother come out of coma?

Hello,

Welcome to icliniq.com. I have seen all the attached reports (attachment removed to protect patient identity). Your grandmother has posterior circulation stroke, which has involved very compact structures of the brain (pons, midbrain, and thalamus). These structures of the brain have very compact fibers. There is no specific medication to bring the patient out of a coma. The brain has a feature of plasticity, by that, the surrounding normal structures of the brain may start taking function of the damaged areas. But, that is a slow process. At 82 years of age, it is much slower and very limited. So,recovery is unpredictable. Medications can be given only to prevent further stroke and supportive life care. Sorry to say, possibly she will remain in bed bound state forever.
