OK, some call it sundowners and some say it's manipulation. In the evening mother begins screaming and being uncooperative with caregivers for eating, meds, changing underwear and putting on pajamas. I often think that it is by that time she realizes I'm not coming over which is what she really wants, and when I get there she is full of smiles and apologies for any bad behavior or says she didn't do it or didn't mean it. Is there a medicine for this? Thanks.
