I agree that I am glad he woke from his coma because I have been through a comatose state myself. I have been seeing a neurologist for the last year and half because of black spaces in my memory due to being through 3 severe bouts of depression in the last 5 years or so. The neurologist told me and my mother the blank spaces were most likely memories I once had of the particular event but became blackened due to the over-usage of headache medicine I took during this time without consideration of the effects to my memory.
He was correct on this and it was documented as proven so, however, about 2 weeks into cognitive therapy to try to undo the damage and re-learn of my memories I started about almost 1 year ago now; I blanked out and my eyes were said to have rolled into the back of my head. They had thought I had a seizure of some sort, but when I did not wake for the next week while hospitalized at the nearest hospital to the therapy clinic afterwards...they knew I had went into a coma for some reason. I spent the next 8 months in a comatose state, and the doctors told my parents it was unlikely I'd wake now, and that if I woke up that I was likely to be in a vegetative state for the rest of my because of the severe damage done to the nerves in my brain from the aspirin in the headache medicines I once used as a release from pain caused me.
I am now nearly 24 years old and prospering since I attend a university with a GPA of 3.87 on average, and I am perfectly healthy in mentality as I can be after the episode I had with the coma and depression that may have been part of the cause to it. The neurologists don't understand this at all or why I am as functional as I am regularly, but they do know in some ways I was blessed to be as mentally functional as I am daily since many never recover from the damage in the nerves I have and to be this way. Neurology is a hard science that relies on numbers, tests, experimentation, research and more; so a coma is one thing that can stump them if they find no true cause for it or a reasonable explanation for it to occur in a patient, as mine was never truly proven to be instigated by a overdose of aspirin at all or my depression itself.
