Benefits of Hyperbaric Oxygen for Cognitive Improvement for the Elderly

As people get older, they start to suffer from such conditions as dementia or Alzheimer’s. One treatment in particular that has received a lot of attention lately is using hyperbaric oxygen therapy by Aviv Clinics – HBOT. There is still a lot of research to be done on this topic, but this has shown a lot of promise in elder patients who have received these treatments. This will take a look at these studies and what the benefits are for this type of treatment for elderly patients.

What is Hyperbaric Oxygen Therapy?

This treatment approach requires a person to breath in pure oxygen while in a pressurized tube or room. The air in this room or tube is pressurized to more than 3x higher than the normal pressure, which allows the lungs to take in more oxygen. Due to the increase oxygen intake, the body can better circulate the oxygen through the body and helps to stimulate the growth of stem cells and growth factors to aid in healing. This has been a long used therapy for treating such conditions as decompression sickness (condition caused by scuba diving), treating wounds that don’t heal as a result of such issues as diabetes, and to treat air bubbles in blood vessels.

Benefits of Using HBOT for Cognitive Improvement

Hyperbaric oxygen therapy offers a variety of different benefits for cognitive health, such as:

Increases Blood Flow to the Brain

According to studies, people who undergo this treatment have much better blood flow to the brain than those who don’t receive this treatment. This increased blood flow is beneficial to cognitive performance as this can reduce the risk of issues like deterioration in the brain.

Improves Brain Metabolism in Patients with Alzheimer’s

A study in 2019 took a look at a 58-year-old woman who had been suffering from cognitive decline for around 5 years. She reported that she had better focus and improved memory with a decrease in disorientation after receiving HBOT for 40 sessions. Scans on this patient showed an improved brain metabolism for that patient.

Helps Treating Patients with Vascular Dementia

This form of dementia is as the result of damage to those small blood vessels in the brain. This is a common issue for people who have had multiple strokes or have had heart issues for a long time. HBOT is an effective treatment tool here because of how it increases the blood flow to the brain, even with these damaged blood vessels.


There is still a lot of research to be done on hyperbaric oxygen therapy before it can be officially used as a treatment for elderly patients who are suffering from cognitive decline. Even still, this has been shown to be a highly effective treatment that can have a significant impact on the cognitive performance for any patient, especially elderly patients. This treatment has been in use for a variety of conditions since the early 2000’s and it is becoming a great options for elderly patients who haven’t found another effective treatment.
