April 19, 2026 updated by: Shay Efrati, Assaf-Harofeh Medical Center

The Profile of Cognitive Function of Patients Who Had Neurocognitive Evaluation at the Sagol Center for Hyperbaric Medicine and Research

In the investigator's institute there is ongoing treatment of different patients with cognitive deficits using Hyperbaric oxygen therapy (HBOT). These patients undergo neuro-cognitive function computerized tests before and after treatment.

The aim of this study was to retrospectively evaluate the cognitive changes before and after HBOT in different patients populations.

Detailed Description

Retrospective analysis of patients suffering from chronic neuro-cognitive deficits due to different conditions, treated at Sagol center for hyperbaric medicine and research, Shamir (Assaf Harofeh) Medical Center, Israel

Patients included if they had at least two neurocognitive tests, before and after Hyperbaric Oxygen Therapy (HBOT). The study was approved by the institutional review board of the hospital.

Patients were treated with 40-60 daily hyperbaric sessions, 5 days per week. Each session consists of 90 minutes exposure to 100% oxygen at 1.5-2 ATA.
