Hyperbaric oxygen therapy, HBOT, is proving to be a very viable and lasting solution treat the debilitating symptoms of long Covid. Research coming out of Israel showed how oxygen under pressure can repair brain tissue that has been damaged by the virus.

Long-term neurological conditions are some of the most common symptoms associated with a Covid-19 infection, with about 30 per cent of people reporting some level of brain fog, headaches or mental fatigue months after recovering from the virus.

It has left millions around the world unable to work effectively but an innovative treatment used to stimulate stem-cell growth and accelerate tissue repair has proven to be effective in treating longCovid sufferers, a study has found.

Research at the Sagol Centre for Hyperbaric Medicine and Research at Tel Aviv University suggests the Covid-19 virus can damage brain regions responsible for cognitive function, mental status and pain interpretation.

Long Covid patients who received 40 sessions of hyperbaric oxygen therapy (HBOT) over two months showed significant improvement in their cognitive function, compared with those who were given a placebo.

“The study revealed that HBOT can induce structural and functional repair of the damaged regions of the brain and improve the cognitive, behavioral and emotional function of the unfortunate patients suffering from post-Covid-19 conditions,” said Dr Shai Efrati, lead researcher on the project.

“The research suggests that the development of post-Covid-19 conditions related to the central nervous system includes direct neurological injury mostly in the frontal lobes — the area of the brain that plays a major role in cognitive and mental functions.

“In some patients, the virus can penetrate the brain through the cribriform plate, the part of the skull located just above our nose, and trigger chronic brain injury presented as cognitive decline, such as brain fog, loss of concentration and mental fatigue.”

The study involved 73 patients with reported post-Covid-19 cognitive symptoms, such as inability to concentrate, brain fog, forgetfulness and difficulty recalling desired words or thoughts.

Symptoms had significantly affected their quality of life and persisted for more than three months after a positive PCR test.
