Covid’s condition leaves patients with symptoms similar to “traumatic brain injury”

Australian research has found the main cause of one of the mysterious symptoms of chronic Covid’s disease – a mental disorder caused by “brain fog”.

By identifying the nerve toxins responsible for the long-term brain blurring in patients with Covid’s disease, doctors say they will be able to test possible treatments for the condition and find new ways to treat other cognitive impairments.

However, new research also reveals some bitter truths for people suffering from cerebral palsy before treatment is available.

Long Covid – This is a detailed description of the long-term conditions experienced by some people infected with the Covid-19 virus and includes fatigue, fever, joint pain, cough, headache, and difficulty concentrating or thinking clearly.

Researchers have proven that brain fog is a real pain, and while studying patients with Covid for a long time, they found what they thought was its source in the body.

Bruce Brew, a neurologist at St. Vincent Hospital and the University of New South Wales, made the discovery while studying the long-term effects of Covid with colleagues.

Their work proves that brain fog is a real condition.

“This confirms that there is an organic basis for cognitive impairment and gives us that goal – there has long been controversy about Covid and related cognitive impairments,” Dr. Brew told the Daily Mail Australia.

“It explains to us what is the basis of cognitive impairment and gives us a purpose.”

Brain nebula refers to problems with memory, attention, and performance function associated with other long-term Covid symptoms.

“There are some drugs that have been developed and are being tested for other diseases that could affect this pathway. This will allow us to look more closely and perhaps explore other treatments.”

“These things (test drugs) are always annoying, but they have a purpose, and we hope that with the support of other researchers around the world, we can quickly track them down …

In St. Vincent’s study of 128 patients over a 12-month period, the researchers found that long-term Covid’s cognitive effects may last for more than a year, and for some may be permanent.

Research shows that one in five patients has cognitive problems, which can be observed in a certain way in the body.

When infected, Kynurenin’s pathway, which is responsible for the balance of energy, mood and immune system, raises levels of the two chemicals to a detrimental effect.

Infections in the system can lead to an increase in quinolic acid and 3-hydrocyanthranilic acid.

Nerve toxins are a bit of a virus

Nerve toxins are formed when a small “lice” of the virus stop an important reaction of the immune system, and chemicals that damage nerve cells and later brain cells increase.

Dr. Brew said the “lice” of the virus, which had to be cleared after the patient recovered from Covid, stimulated this pathway in the immune system and problems with brain fog.

This pathway is designed to slow down the immune system once it has finished its work.

“It’s as if someone was in the parking lot and got gas in his leg – this immune system is over-driving – the foot of the road is braking and the car is moving forward, but it’s causing a lot of damage to the brakes and the car itself,” Dr. Brew said.

The process can be harmful and potentially irreversible nerve damage.

“It damages nerve cells and prolonged exposure kills some brain cells,” he said, adding that it could lead to long-term brain damage similar to “traumatic brain injury”.

“We do not know to what extent patients with chronic Covid have identified irreversible damage than those who are in the repair phase against chronic impairment.”

The Daily Mail Australia has previously reported the findings of Dr. Brue’s peers, a senior doctor at St. Vincent’s Hospital who observed that people with more than five symptoms at the time of his infection could develop long-lasting symptoms of Covid.

Dr. Anthony Byrne also said that young and physically fit people are not kept in a “highly volatile and debilitating” condition.

“I saw a young man who worked at a high level, he had a great job and has not been able to work since,” he said.

This patient, Dr. Byrne, is unable to work because he suffers from insomnia, fatigue and “brain dysfunction”.

He will not be able to complete difficult tasks, and some days he will not be able to find words.

Both Dr. Byrne and Dr. Brue stressed that despite the removal of barriers and easing of restrictions, Covid is not over, and that his real impact is beyond hospitalization.

“I think it’s a mistake to estimate Covid’s impact on society on the number of people admitted to the ICU,” Dr. Byrne said.

“Long Covid has a significant impact on the community and individuals, and people need to be vaccinated – which seems to reduce Covid’s longevity and severity – and at the same time we understand that this is not the last thing we can do. Or. We need to be reasonable,” Dr. Brew said. .


Long Covid is used to show signs of coronavirus that persist for months after the initial infection.

If the symptoms persist for more than four weeks after the initial infection, the person is considered a long-term Covid.

Patients may experience a number of symptoms, including fatigue, chest pain, shortness of breath, dizziness, memory loss, and changes in taste and smell among other illnesses.
