Assisted Living Deductions

Doing my father's taxes who is 97 and has lived in assisted care facility for several years. This is the first year he has not done his taxes by himself and me having to help him. Where would I apply the deduction for the facility monthly expense? He is not a dependent on any other taxes. I would think that it is associated with medical expenses which I would also add insurance premiums and medical expenses not cover as well.

 I'm I correct in that aspect?
