How can I claim my mother who lost her job after working for a month but made more than the max for a depended?

I supported my mom this year who lost her job due to a work injury. She only worked for 2 months this tax year and made more than $4,700, therefore I cannot claim her as a dependent. But I have provided for her for almost 11 months now and she lives with me. Is there a workaround for this? Or I cannot be the head of the household?
