 She underwent a total of four dives under Hyperbaric Oxygen ( 2 dives on 1/17 and 2 dives on 1/18). Neuropsychologic assessment on 1/18/96 revealed marked cognitive impairments with defects in anterograde memory, praxis, associative fluency, attention, and speed of information processing. She was discharged home on 1/19/96 and returned on 2/11/96 after neurologic deterioration. She progressively developed more illogical behavior, anhedonia, anorexia and changes in sleep pattern. She became completely dependent and could not undergo repeat neuropsychologic assessment in 2/96. She was later transferred to another care facility against medical advice. The etiology for these changes became complicated by a newly discovered history of possible ETOH abuse and usual "anxiety" disorder.
