My grandmom is suffering from Alzeimer's disease since last year. She also have diabetes. One day when she was sleeping,she suffered from hypoglycaemia & get unconscious while sleeping. Because of that she also suffered hyponatremia which leads her to coma for 1 day. Now her levels are okay but she is too weak & unable to speak anything. You can say it is hyper anxiety or depression. She can't eat anything by will so we use rice tube.
