Do we have any other caregiving option for my mom outside of a nursing care facility?

Hoping you can help or direct me to someone that can. Brief Hx: Mom suffered a major stoke 17 year ago, partial left sided paralysis, vision effected etc. over the years her condition has worsened, as one would expect. Mom has been in a few asissted living care facilities, over the past few year her level of care has risen. We just moved her less than a year ago, as the prior faciity dropped her on several occassions, barely spoke english, very expensive, very unresponsive when paged, to take mom to use toilet. The new facility required Mom to spend a few days there during day care program, Once that was done, a few other stipulations were required: 1)We have pt for Mom thru the asissted living facility to help strenghten her legs, we did this, it took several months before they began her sessions, and the sessions have already reduced in time and effort on the therapist part. Also we were required to have someone at Kaiser come out twice to teach Mom on using the slideboard, as this is what the caregivers use, to transfer patients to commode, or wheelchairs etc. My mother participated and completed this requirment also. Although the caregivers have never used this method of transferring my mother. My mom used to be very nice and patient person. She obsesseses on every little negative thing now, and paging a caregiver and it taking various times for a response, her anger builds and she can be quite "flippant" and am sure she has made some very unpleasant remark to the caregivers, We have just been notified that we need to fing my mother another facility, for reason, she needs much more care then they can provide. (my mother does take up to one hour of assistance from a caregiver in the am and in the evening. Can they do this even though we satisfied there every request, and trial so that they knew exactly what it was my mother would need in the way of care. Do we have any other option outside of a nursing care facility? other than the physical restrictions, my mother has retained her mind and other than some age related deterioration, she remains fairly sharp, although wonder if this is working againt her at times. part 2 of my question is, my mothers "outbursts" while to me the reaons seem somewhat justified, although very minor, her means of expresion are totally unacceptable. once she has made her nasty comment or yelled at the caregiver, she is done, and though usually she remembers getting upset she doesnt view it as a big ordeal. (her and i used to have problems in this area, I followed my sisters way of handling it andmy mom and i are fine now) but i do understand their side of it as well. Could thi be signs of some underlying problem, ie medications, chemical imbalance, or early stages of dementia? or just plain crothity old age syndrome? If these questions cannot be answered by you, could you please point me in a direction where i might find some anwers or assistance. (btw my mother is in northern california area. thank you
