Parents getting alzheimers....

Family emergency time....my mother is getting ancient and for some reason after 50 years of my mother paying my worthless younger brothers way through life he no longer wants her around...now I have to choose...nursing home or tackle another alzheimers person...once they have alzheimers they are still your relatives but they don't know you...I have been down this road already before...Going to be another soul searching sleepless night...I knew my worthless brother would pull this crap after years of living off of her generosity he now does not want to put up with her anymore and just wants to dump her off...??? He can't make it on his own, never has been able to his mother has always supported him...why should I have to take care of her now? Another road trip next Saturday to go see first hand what is going on and lots of calls and probably some talks with attorneys to see what the legalities are...what another freakin PITA headache because of a worthless family member...
