Trial Outcomes & Findings for Hyperbaric Oxygen Therapy for Cognition in Diabetic Elderly at High Dementia Risk (NCT NCT03036254)
NCT ID: NCT03036254
Last Updated: 2025-08-11
Results Overview
This analysis involves 11 cognitive performance variables, each measuring a specific aspect of cognition. In general, higher scores indicate better performance (Digit Symbol measures processing speed, Semantic Fluency measures verbal fluency, Word Recall Task measures immediate verbal memory, Delayed Word Recall Test measures delayed verbal memory, and Recall Unit measures immediate and delayed story recall), except for two variables (Trail Making Test Part A measures processing speed, Trail Making Test Part B measures cognitive flexibility) that measure time (where higher values indicate worse performance). These variables are standardized using Z-scores, which allow for combining and comparing values across different scales. The standardized values (Z-scores) of all 11 measures are averaged to create the composite score. Full range of composite score is -1 to 1. Higher composite Z-score reflects better cognitive performance and more favorable outcomes.

HBOT Intervention
The multiplace HBOT unit at Asaf Harofeh. The inside looks like an airplane, with comfortable chairs for 11 subjects and the nurse who stays throughout the session. The HBOT protocol is 90 minutes, 5 times/week, 60 sessions, 100% oxygen at 2 ATA with 5 minute air breaks every 20 minutes.
|
Sham Intervention
The sham condition replicates all experiential aspects of the HBOT therapy except for the degree of pressure and oxygen levels. The sham condition exposes subjects to 1.1 ATA, which provides a pressure sensation in addition to the noise of air circulation. Pressure then decreases very slowly during the next half hour; in the last 5 minutes of the session, air is circulated again with its related noise.

SECONDARY outcome
Timeframe: Baseline, 12 weeks, 6 months, 12 monthsPopulation: Data not collected due to decision not to administered instruments. This decision was based on participant frailty and protocol intensity-not technical issues or non-compliance-and was made to ensure feasibility and ethical conduct of the study. The NIH computerized cognitive test was never administered, and no data was collected at any time.
The sum z-scores for 3 computer-based tests (not language dependent), developed through NIH; EXAMINER assessing executive abilities: http://examiner.ucsf.edu). Early in the study, it became clear that participants-older adults with significant frailty, multiple chronic conditions (average \>4 per participant), and high medication burden (mean \>5 medications)-were finding the assessment protocol burdensome. The protocol already required repeated cognitive testing, MRI, FDG-PET imaging, and other assessments, leading many participants to report fatigue and difficulty concentrating. To prioritize participant well-being, decision made not to add the NIH computerized cognitive tests. The existing paper-and-pencil battery was well-established, sensitive to cognitive changes, and adequately covered executive function and episodic memory. The NIH computerized cognitive test was never administered, and no data was collected at any time.

Clinical Dementia Rating-Sum of Boxes (CDR-SB), which summarizes impairment in 6 domains (memory, orientation, judgment/problem solving, community affairs, home/hobbies, and personal care) based on subject and informant interviews. Scores in each of these are combined to obtain a composite score ranging from 0 (no symptoms of dementia) through 3 (severe symptoms of dementia). Total scale from 0-18. Higher scores indicating worse cognitive status.

This is a 21-item, self-report questionnaire that measures attitudes and symptoms of depression during the last week (i.e. mood, feelings of hopelessness, failure, guilt, self-esteem, etc.). Each question has a set of at least four possible responses, ranging in intensity. Total scale 0-63. Higher scores indicate more severe symptoms of depression.

HBOT Intervention
n=77 participants at risk
The multiplace HBOT unit at Asaf Harofeh. The inside looks like an airplane, with comfortable chairs for 11 subjects and the nurse who stays throughout the session. The HBOT protocol is 90 minutes, 5 times/week, 60 sessions, 100% oxygen at 2 ATA with 5 minute air breaks every 20 minutes.
|
Sham Intervention
n=78 participants at risk
The sham condition replicates all experiential aspects of the HBOT therapy except for the degree of pressure and oxygen levels. The sham condition exposes subjects to 1.1 ATA, which provides a pressure sensation in addition to the noise of air circulation. Pressure then decreases very slowly during the next half hour; in the last 5 minutes of the session, air is circulated again with its related noise.
