T₁: 0 min prior to hyperbaric oxygenation or hyperbaric oxygenation, T₂: 0 min after hyperbaric oxygen therapy or hyperbaric oxygen therapy, T₃: 30 days after hyperbaric oxygen therapy or hyperbaric oxygen therapy.

HBOT = hyperbaric oxygen therapy, MoCA = Montreal Cognitive Function Assessment; MMSE = mini-mental state examination, NBH = normobaric hyperoxia.
