The others who said basically (a) Medicade and a home are probably
something to consider given the options, and (b) consult a good elder
care attorney, are both absolutely correct.  Another bit of confusion
here is that Medicaid is a federal program but it's administered by the
individual states, each of which have individual laws regarding it.

My wife has EOAD, she hasn't turned 60 yet, and I'm just over.  We still
have kids in school, so the "protect the inheritance" thing is important
to us as well.  One thing we're looking into is a SPIA (Single Payment
Immediate Annuity, or something close to that...).  The basic concept is
that, at least in Massachusetts, Medicaid won't touch income, just
assets.  So when the time comes, if you (the caregiver) put everything
you have into a SPIA and reduce your assets below Medicaid's mandated
level, they start paying immediately and you still have an income.

Also, it appears, again at least in Massachusetts and at least so far,
that Medicaid will NOT take the house and it can be passed on to heirs.

Again, check with that elder care attorney in your state and also with a
good financial planner.  As with everything else in life, "your mileage
may vary".
