Neurocognitive testing and functional evaluation sessions take 2- 3 hours each, or about 5 hours combined. The subject is free to take breaks throughout testing sessions, which will take place over one or two days. Subjects participate in assessments up to four times (Baseline, after 6-8 weeks; 12-16 weeks; and at 18-24 weeks), or up to 20 hours (5 hours x 4 time points). The investigators anticipate about 30 subjects will participate in assessments and training.
