"He was paranoid, like, all the time. But memory loss, I saw that, as well," Bobby Thomas recalled. "Every single day, he complained about -- about having a headache."
"His mood would change, and he would also isolate himself sometimes," Smith added. "[Demaryius] would tell me, he was like, 'Mom, I don't know what's goin' on with my body -- I gotta get myself together.' And he said, 'I don't feel like myself anymore.'"
