Mom seems to be misunderstanding everything. It's hapened before but she came out of it..maybe not this time. Tells me things that are just not happening, bossy and rude to her caregiver (makes her cry), thinks I'm my sister (died 13 years ago). I think she's forgotten how the thermostate works and asked me recently on the phone if I was the "real" daughter. Doctor upped her nerve pill yesterday. What do you think this is? Please anyone, respond. Need advise soon.
