Hi, welcome to our site. I am Dr Saumya Mittal, MD. Read your query. That is a very significant question and i appreciate your problem. I will try my best to answer your query The concept of brain death needs some very specific features.The problem with brain death is that almost every feature that is supposed to be in favor of brain death can also be caused by another cause. So no one single sign can be confirmatory of brain death. besides, seizures also happen due to more than one cause. There may be a structural brain lesion, there may be a severe infection (sepsis), there may be sevre metabolic derangements (again of many types). And once a seizure happens, the patient may become unresponsive for a long period of time, say even upto 72 hours. The physical signs can infact mimic brain damage. I will always suggest at least an EEG if I was to declare a patient as possibly having brain death, I will suggest the same to you. Besides with heavy sedation, it is difficult to say whether there is brain death, or is it a part of the injections. I hope this helps you. Inform the reports mentioned above/if any other so I can be of help further. I have given you the answer to the maximum considering the information provided.
