I have moved in with my mother to care for her at night and on the weekends. She has a caregiver during the week as I work and am gone. She has a monthly income under $2000 and until Sept 2013 had a savings to pay for home care. Since Sept 2013 , I have paid for home care and her income has gone for bills, food, etc. She has filed for Medicaid but was denied-she is appealing.

You cannot claim her expenses as your deductions, sorry.
