Hi I am Dr Mittal. I have read your message. I think I can help you. I would ideally need more information about the way the symptoms have developed. However, overall, the syndrome seems to be suggestive of infective pathology like Creutzfeldt jacob disease or meningoencephalitis. There is an alternative possibility that there was a preexisting dementia, and due to that, the seizures have resulted in violent behavior. You want to know about the mechanism of the illness. It would be somewhat difficult to explain this to you. It is a complex basis of anatomy and physiology. But I will try my best to explain it to you. Simply put, imagine that there is a brain which is getting damaged, slowly with age. This may cause memory issues. Then, the brain damage causing memory issues is called dementia. In other words, it is obvious that there is brain damage if the patient has dementia. Furthermore, when the patient develops a seizure, it is like a shock of current that spreads through the brain. This shock, in normal people is stopped by the surrounding normal brain. But when the brain is already damaged, the defenses of the brain are affected as well. This may lead to abnormal behavior- what is often known as delirium. Delirium happens more easily in people with dementia then those without dementia. The speed of the brain damage may vary. Slow causes are like commonly known Alzheimers disease etc. Fast are infective pathologies like meningoencephalitis and CJD etc. I have tried to explain it very simply. The actual neurological grounds are much more complex. This is an oversimplified model so that you can understand what is going on and contribute positively in your mother s illness. Feel free to contact me for clarification on any point that you wish. Best of luck, Dr Mittal
