I understand your concern towards your mother. Whatever you have mentioned appears to be due to an acute neurological event, like delirium, stroke or even a seizure activity. However more clarity is needed regarding her problem to decide on severity of the condition. I suggest you consult a neuropsychiatrist for a detailed evaluation and appropriate treatment. I would also be more than happy to help you with that if you are looking for further online information. You can directly consult with me through Practo as needed. Online chat consultation is available.
