I am a sister. My brother (62), is single and disabled. My brother is living with our other sister. Only income is SS disability. Seeing Dr.'s. Diagnosed with TBI. Unable to make decisions for himself. An attorney has suggested guardianship but after reading the definition, that doesn't seem the right direction. I am 72, my sister 69. Just want to make sure he is cared for and possibly rehabilitated while we are able.
