Oxygen therapy could be the latest solution provided by doctors to treat debilitating symptoms of longCovid, after research in Israel showed how it can repair brain tissue 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.
In some patients, the virus can penetrate the brain and trigger cognitive decline such as brain fog, loss of concentration and mental fatigue
Dr Shai Efrati,
lead researcher
LongCovid 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, behavioural 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.
The Dubai clinic increasing the pressure on cognitive decline
During the treatment, patients entered an oxygen chamber usually used by deep-sea divers to decompress safely outside of the water, rather than when submerged.
The chamber delivers 100 per cent oxygen by mask during each 90-minute session at pressure equivalent to that found 10 metres underwater.
MRI brain scans were completed to test therapy progress, while subjects took part in cognitive tests and had their symptoms evaluated by a doctor.
Substantial increase
The treatment is offered at the Aviv Clinic in Dubai, where an evaluation for long Covid starts at Dh25,000 ($6,806).
That includes a comprehensive neurocognitive evaluation, physical performance assessment, fitness test, brain scan, blood tests, chest x-ray, smell and taste test, as well as a full medical checkup by a doctor.
Costs do not include the price of treatment, which can run into the tens of thousands of dirhams, depending on the severity of the condition.
Aviv Clinics used oxygen therapy last year to treat a previously healthy and athletic 56-year-old UAE resident suffering from long Covid, months after his release from hospital.
“This client told us that reversing the executive function effects of long Covid, such as memory and flexibility in thinking, as well as physical performance attributes were both very important quality of life priorities,” said Mike Frayne, chief executive of Aviv Clinics Dubai.
“When we measured the pre and post-treatment executive function skills, we saw a substantial increase in executive function performance.
"From a physical performance perspective, he was able to go from being limited to light jogging due to breathlessness to reporting that he returned to mountain running and rowing after the full HBOT treatment.”
The therapy is more commonly used to treat wounds and repair damaged tissue by flooding it with oxygen rich-plasma to supercharge the healing process.
It has also proved effective in treating brain injuries and degenerative disorders, such as Alzheimer’s, and can now be used effectively in the most serious cases of long Covid.
Researchers at the University of Cambridge say 78 per cent of long Covid patients experienced difficultly in concentrating, while 69 per cent said they had brain fog and 68 per cent reported forgetfulness.
“Millions of those who have recovered from Covid-19 are experiencing debilitating symptoms which persist for weeks, months or even two years following their original infection,” said Dr Amir Hadanny, chief researcher and head of global clinical operations at Aviv Clinics.

Ten tax points to be aware of in 2026
1. Domestic VAT refund amendments: request your refund within five years
If a business does not apply for the refund on time, they lose their credit.
2. E-invoicing in the UAE
Businesses should continue preparing for the implementation of e-invoicing in the UAE, with 2026 a preparation and transition period ahead of phased mandatory adoption.
3. More tax audits
Tax authorities are increasingly using data already available across multiple filings to identify audit risks.
4. More beneficial VAT and excise tax penalty regime
Tax disputes are expected to become more frequent and more structured, with clearer administrative objection and appeal processes. The UAE has adopted a new penalty regime for VAT and excise disputes, which now mirrors the penalty regime for corporate tax.
5. Greater emphasis on statutory audit
There is a greater need for the accuracy of financial statements. The International Financial Reporting Standards standards need to be strictly adhered to and, as a result, the quality of the audits will need to increase.
6. Further transfer pricing enforcement
Transfer pricing enforcement, which refers to the practice of establishing prices for internal transactions between related entities, is expected to broaden in scope. The UAE will shortly open the possibility to negotiate advance pricing agreements, or essentially rulings for transfer pricing purposes.
7. Limited time periods for audits
Recent amendments also introduce a default five-year limitation period for tax audits and assessments, subject to specific statutory exceptions. While the standard audit and assessment period is five years, this may be extended to up to 15 years in cases involving fraud or tax evasion.
8. Pillar 2 implementation
Many multinational groups will begin to feel the practical effect of the Domestic Minimum Top-Up Tax (DMTT), the UAE's implementation of the OECD’s global minimum tax under Pillar 2. While the rules apply for financial years starting on or after January 1, 2025, it is 2026 that marks the transition to an operational phase.
9. Reduced compliance obligations for imported goods and services
Businesses that apply the reverse-charge mechanism for VAT purposes in the UAE may benefit from reduced compliance obligations.
10. Substance and CbC reporting focus
Tax authorities are expected to continue strengthening the enforcement of economic substance and Country-by-Country (CbC) reporting frameworks. In the UAE, these regimes are increasingly being used as risk-assessment tools, providing tax authorities with a comprehensive view of multinational groups’ global footprints and enabling them to assess whether profits are aligned with real economic activity.

if you go
The flights
Etihad and Emirates fly direct to Kolkata from Dh1,504 and Dh1,450 return including taxes, respectively. The flight takes four hours 30 minutes outbound and 5 hours 30 minute returning.
The trains
Numerous trains link Kolkata and Murshidabad but the daily early morning Hazarduari Express (3’ 52”) is the fastest and most convenient; this service also stops in Plassey. The return train departs Murshidabad late afternoon. Though just about feasible as a day trip, staying overnight is recommended.
The hotels
Mursidabad’s hotels are less than modest but Berhampore, 11km south, offers more accommodation and facilities (and the Hazarduari Express also pauses here). Try Hotel The Fame, with an array of rooms from doubles at Rs1,596/Dh90 to a ‘grand presidential suite’ at Rs7,854/Dh443.

What is the FNC?
The Federal National Council is one of five federal authorities established by the UAE constitution. It held its first session on December 2, 1972, a year to the day after Federation.
It has 40 members, eight of whom are women. The members represent the UAE population through each of the emirates. Abu Dhabi and Dubai have eight members each, Sharjah and Ras al Khaimah six, and Ajman, Fujairah and Umm Al Quwain have four.
They bring Emirati issues to the council for debate and put those concerns to ministers summoned for questioning.
The FNC’s main functions include passing, amending or rejecting federal draft laws, discussing international treaties and agreements, and offering recommendations on general subjects raised during sessions.
Federal draft laws must first pass through the FNC for recommendations when members can amend the laws to suit the needs of citizens. The draft laws are then forwarded to the Cabinet for consideration and approval.
Since 2006, half of the members have been elected by UAE citizens to serve four-year terms and the other half are appointed by the Ruler’s Courts of the seven emirates.
In the 2015 elections, 78 of the 252 candidates were women. Women also represented 48 per cent of all voters and 67 per cent of the voters were under the age of 40.

Who was Alfred Nobel?
The Nobel Prize was created by wealthy Swedish chemist and entrepreneur Alfred Nobel.
- In his will he dictated that the bulk of his estate should be used to fund "prizes to those who, during the preceding year, have conferred the greatest benefit to humankind".
- Nobel is best known as the inventor of dynamite, but also wrote poetry and drama and could speak Russian, French, English and German by the age of 17. The five original prize categories reflect the interests closest to his heart.
- Nobel died in 1896 but it took until 1901, following a legal battle over his will, before the first prizes were awarded.
