Is form T2201(Disability amt.) appropriate as Mom claims her rent at a long term care facility and permanently placed in wheel chair in 2018?

My mom stopped walking in 2018 and requires assistance for basic functions of eating, toileting, etc. I wonder if she is to claim both her rent at the facility as well as the disability amount. I have not considered the Disability Amount previous years but now that she is in a wheel chair she is disabled both physically and mentally (dementia).
