When Grayson discovers Maniac, his condition could be described as what?

When Grayson found Maniac Magee at the zoo, he thought that "the kid looked terrible."  Maniac had been living homeless for so long that his clothes were "rags" and his body was "was bony and dirty and scratched."  Maniac was not only horribly dirty, but he was also incredibly weak and hungry.  Grayson took him to the equipment room in the bandshell.  The older man fed Maniac soup, which was all he had with him.  Maniac told Grayson that his body had gotten scratched up on "'some picker bush.'"

Grayson found out that Maniac Magee was still hungry after only eating soup, so he went out and brought him back a sub sandwich and a large box of snack cakes.  Maniac was covered with dirt after living at the zoo and he took a shower for an hour in order to get himself clean.
