Coloring book pages from 17 year old girl with autism: (a) before beginning HBOT at 1.5 atm/100% oxygen; (b) after one week of HBOT (5 sessions at one hour each), she is beginning to create patches of color to fill in a space; (c) after 3 weeks of HBOT (about 15 hours of HBOT), she uses correct colors for Winnie the Pooh and Eyore, and the foliage except for the tree trunk; and (d) after 5 weeks of HBOT (20 hours of HBOT), she begins to respect borders and boundaries and even outlines the inner border with color. After 6 months, her coloring abilities remained stable. Pictures courtesy of Carol L. Henricks, MD. Credit: Permission for use of drawings granted by the Journal of American Physicians and Surgeons.
