"nursing home" vs "memory care" with respect to Medicaid/Medi-Cal

Hi,

  I understand that once a person is in a 'nursing home', paying with savings, and their savings eventually run out, then Medicaid (or Medi-Cal in Calif) will pay for the care.

  Is 'memory care' the same as a 'nursing home'? My mother has Alzheimers, and we'll be moving her to a 'memory care' soon, so I'd like to understand the semantics....

thanks
