She's 76 years old. She asks me what the date is about 3 times a day. The day before yesterday she said something like ''Oh, so it's September already?''. Yesterday she asked me if it's May or April. She doesn't orientate in time at all. She forgot how to cook anything. Although, she could still cook 2 years ago. The only thing she still knows how to cook is pancakes. When she opens the fridge she can't see anything. She says that it's empty, but it's not. I have to take food out of the fridge and give her. She was much different 2 years ago. How is it possible to change like that in just 2 years?
