They need treatment even after they leave hospital.

There are concerns that a small number of people can suffer long - term or permanent lung damage, as well as persistent weaknesses, disorientation and anxiety, reports VOA.

Susan Creswell left the hospital in April but she hasn't fully recovered. It continues to breathe and feels powerless.

The 65-year-old would retire in October, but now it's not safe if she can get back to work.

Mrs. Creswell says she had not felt well for two weeks before her condition deteriorated rapidly. She was taken to the intensive care unit.

The doctors had to link him with artificial breathing while he was in an artificial coma. She had complications with her heart and kidneys.

The isolation had just begun and Mrs. Creswell couldn't have met her son and her two daughters.

A very good nurse held my hand and told me that the only way to be treated was by putting me in a coma. It was horrible and my first thought was children, but I had no alternative. I said can you tell my kids I love them?

The medical journal Lancet published a study by doctors who have treated 153 coronary patients.

They have described as <x0... a picture of brain complications in patients with severe cases of COVIDD-19л.

According to the study, a third of patients had experienced “a different state of mind as brain inflammation and similar psychosis and degencian”.

Researchers say that there is a need for broader studies.

Mrs. Creswell suffers from bad dreams, and it is not certain whether she is experiencing the experience of the hospital coma again or if she is still having the same dream she had in the hospital.

The first few nights I was afraid to go to sleep because the first night I saw the same dreams I had when I was in a coma”

Doctors at the University City Hospital in Britain have developed a team for emerging patients, including respiratory and intensive care specialists, as well as physical therapists and psychologists.

They consult with hundreds of patients over the phone.

Charlotte Bolton, a hospital doctor and professor at Nottingham University, says she has seen a wide range of symptoms.

Breathing, coughing, fatigue, muscle weakening and restrictions on daily activities. But some also have scary dreams, they don't even remember being in hospital”, she says.

She adds that some former patients cannot get back to work because they have memory problems. Medical professor says that it is early to determine the percentage of patients with long - term consequences.

The longer they stayed in the hospital, the heavier the case with COVID. The need for intensive care, or for a large amount of oxygen, is identifying which patients are most likely to have constant symptoms for six weeks or more”, she says.

Dr. Sarah Linford, intensive care specialist, says some patients are coping very well, despite very low oxygen levels. This means that doctors cannot immediately determine which patients may experience an immediate deterioration. Doctors also are reluctant to use respirators unnecessarily.

“Artificialization is used for a state that is treatable, one of the main factors to lay someone in intensive care unit. The answer is yes, for it changes the way air enters the lungs”, says Dr. Linford.

lung - injury specialists are also studying patients with COVID-19 and feel that there are similarities to other serious lung diseases. Professor Gisley Yankees, an experimental medical researcher, relates three X - ray. First, they're filled with air.

They're in a normal state here, but in those with severe COVID cases, after 7-10 days, there's a inflammation, and all the part that was filled with air, is replaced by inflammation”, he says.

Although most patients are healed, for some, the damage continues. Yankees relates a severely damaged lung of a patient three months after he left the hospital.

It's something like a pulmonary fibrosis, which is a degenerative lung disease. We know that those who are affected by it die within three years of diagnosis, and the reason is that damage is unstoppable”, Prof says. Yankees.

Scientists say it is too early to draw conclusions because the virus is very young. Prof. Yankees says there is an element of genetic tendency in patients with pulmonary fibrosis.

Doctors are currently studying carefully whether the virus may have unexpected long - term implications for both patients and health services.
