My 93 year old father has advanced Alzheimer's, probably at early stage 7. He can no longer independently perform any ADL's, but he can manage a few with mom's constant assistance, cueing and redirecting. He does not recognize family, recalls nothing about his personal identity or history, and has no concept of time whatsoever. He rarely verbalizes, but can (usually incorrectly) answer basic yes/no questions. He has recently moved from only urinary incontinence to intermittent fecal incontinence. He does not wander. Mom (90 years old) functions like she's in her 70's and needs nothing but her hearing aids to live independently. They live with me where I have a realistic sense of their capabilities and daily struggles. Dad is being evaluated for a facility that can provide them either independent and high-level assisted living in the same apartment or memory care support and independent living in two units separated by a few steps down the hall and a locked door. Any thoughts on either arrangement?
