Rehab is always short lived and for an acute/specific reason but not respite care. When I cared for my mom with dementia I started out with short stay respite stays at a variety of facilities. A weekend stay, few days, etc. it was a good way to check out facilities and to get respite for me. She eventually went into an assisted living for about a year and her dementia worsened so we had to move her to memory care. Eventually she went into the hospice unit there before she passed. It is a long hard journey for everyone. I wish I had sought respite care sooner than I did.
