Weakness after typhoid. Of her recovery?

My mother is having diabetes and blood pressure. She also has parkinson due to which she has been exposed to hallucinations and shivering of hands from past 3-4 years. In August 2016, she had complained of fever . Doctor prescribed medicne of same but after few days she fainted & we took her to the hospital. She was diagnosed with high typhoid there which got on her brain. Her condition deteoriated day by day, so was given multi vitamins and anti biotics in high amount because of which she became too weak and was in coma for 10days in hospital. After returning from hospital , she is on bed till today. She has not recovered from weakness from typhoid & her blood sugar levels are also very high- (350) PP. I am very much concerned & wanted to ask whether there are any chances of her recovery? Will she be able to walk again. Plz help.
