My mother suffers from this dreadful disease and went into a home approx 18 months ago, her meds have been tweaked up and down and some changed as they can react badly together in different people, she is on anti depressants but it took several attempts to get the mix correct. One of the biggest improvements came(once she'd settled in) came because she had company all day if she wished and simple activities to pass the day. It's difficult for all of us but at least I don't worry about her nearly so much now. It's a long process and it needs a dedicated doctor to persevere to get the meds just right, at least in the home she has 24 hour care and help if she needs/wants it, good luck to all.
P.s. Discovered urinary infections can cause lots of problems to sufferers, easy to get checked and treat.
P.p.s. No way an expert but hope I can offer a little help or just hope.
