I read your question carefully and I understand your concern. It is difficult to give an answer because we don t know the cause of her hemiparesis. The brain biopsy is taken precisely for that to help determine the cause of the brain damage, without knowing the cause one can t determine whether it s a process which can be stopped and hopefully will recover with physiotherapy or a progressing issue like cancer which could continue to grow further and worsen her condition. When you get the biopsy result and the diagnosis and possibly the CT or MRI report to evaluate how big the damage is feel free to write again with that info so that me or my colleagues can give a more precise answer. I hope things work out for the best.
