wheel tricycle to a 2-wheel bicycle). HBO (188 treatments
total) was discontinued when the patient desired enrollment
in remedial courses at a community college. SPECT
imaging at this time (Figure 19.6, A and B) shows improvement
in perfusion in the ischemic penumbral areas of the
right-sided lesions. The left hemisphere remains intact. In
summary, HBO, when reinstituted following SPECT and
relapse after discontinuation of HBO, prevented further
deterioration and improved SPECT image as well as neurocognitive
function in TBI, demonstrating the benefit of
HBO in the chronic stage of TBI
