How to claim husband who is in Memory Care

Hi, My husband has dementia and was admitted into a Memory Care facility on June 6.  I have been advised that I still include him as a member of my household when I file my  income taxes. Is there a special form to fill out?  Most of his income goes to the memory care facility to pay for his care.  I receive a small part of his social security to help pay for my bills.  So how do I count his income?
