About this study
Official title: The Effect of Hyperbaric Oxygen on the Functional Connectivity of Resting State Neural Networks in Patients With Cerebral Small Vessel Disease
Patients will have a Functional MRI before and after 10 hyperbaric Oxygen treatments.
Read the detailed description
Functional MRI studies will be done before and 4-6 weeks after Hyperbaric Oxygen treatment to assess changes in connectivity of resting state neural networks. 10 hyperbaric treatments at 2 atmospheres absolute for 1 hour at pressure will be administered. A review of symptoms and and thorough clinical neurological examination by an experienced neurologist familiar with these studies will be done before and 4-6 weeks after the hyperbaric treatments.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
hyperbaric oxygen treatmentOther
Patients are treated in a hyperbaric oxygen chamber for 1 hour at 2ATA, 10 times over 2 consecutive weeks, 5 times per week
| Study group | Role | What they receive |
|---|---|---|
| Hyperbaric oxygen treatment | Experimental | HBO for 1 hour at 2 ATA 10 times, administered 5 times per week over 2 consecutive weeks Receives: Other: hyperbaric oxygen treatment |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in average functional connectivity (fc) within the Default Mode Network and the Dorsal Attention Network will be obtained by resting state network (rsn) functional connectivity (rsnfc) MRI.
Functional connectivity MRI of resting state neural networks.
Measured: Change in baseline rsnfc before and 4 weeks after hyperbaric oxygen

Questions about this trial
What is this clinical trial studying?
A study testing hyperbaric oxygen treatment in people with Cerebral Small Vessel Diseases, run by St. Luke's Hospital, Chesterfield, Missouri at 3 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 27 Oct 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was stopped early (reason given: Depletion of Funds and Illness of principal investigator). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in average functional connectivity (fc) within the Default Mode Network and the Dorsal Attention Network will be obtained by resting state network (rsn) functional connectivity (rsnfc) MRI. (time frame: Change in baseline rsnfc before and 4 weeks after hyperbaric oxygen). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Oct 2017; AzTrials last refreshed its copy on 6 Nov 2026.
