I am not too sure about this, whether or not has it
worsened.
I have noticed that my grandma's memory has worsened (in my
opinion, not too sure though). Before that, she has just forgotten
whether we have eaten or not. Doctors didn't say much for this, so
I guess it is just part of ageing process.
But after she had been discharged from hospital, it seems worse.
She has been asking ridiculous questions, like asking me to buy 4D
and Toto (I am underaged, can't go into these shops to buy such
things). She also can't remember most of the things have happened.
For example, she asked where my father is in the afternoon. My
father has already gone off to work in the morning and she asked
this in the afternoon. Somehow, she doesn't seem to know what's the
time of the day either. She has asked to eat breakfast in the
evening.
