[|AI|]  Hello, I am glad to note that your sister has shown recovery from a critical illness. Based on the details, we need to exclude nutritional deficiencies such as vitamin B12, hemoglobin and vitamin D levels.  These can be checked in the blood. If possible, get a CT scan of the brain also done to exclude any bleeding/blood clots.  Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
