(CNN) – One in three people with COVID-19 has chronic neurological or psychiatric symptoms, researchers said Tuesday.
According to a study published Tuesday in Lancet Psychiatry, 34% of Kovit-19 survivors were diagnosed with a neurological or psychiatric condition within six months of becoming infected.
The most common diagnosis is anxiety, which is diagnosed in 17% of those treated for COVID-19, followed by mood disorders in 14% of patients.
Although the neurological effects are more severe in hospitalized patients, the researchers note that they are more common in those treated only on an outpatient basis.
That rate gradually increased as the severity of Govit-19 disease increased. That’s a 39% increase in the number of hospitalized patients, “said Maxim Dockett, a medical research researcher and co-author of a new study in psychiatry at Oxford University.
Researchers also say that cats need to be included in any precautionary measures against the virus.
Our results indicate that brain diseases and mental disorders after COVID-19 are more common in patients after influenza or other respiratory infections compared to other risk factors. We need to see what happens six months later, “said Dockett.
Govt-19 is a ‘brain disease’
This is the largest study ever conducted and includes electronic health records of more than 236,000 COVID-19 patients, primarily in the U.S. The researchers compared their records with those who experienced other respiratory infections. During the same period.
They found that people with COVID-19 had a 44% higher risk of neurological and mental illness compared to people recovering from the flu. They are 16% more likely to experience those effects compared to other respiratory infections.
One in 50 COVID-19 patients had ischemic stroke, a blood clot that affects the brain.
However, there is no need to increase the risk of developing a full spectrum of Covit-19 neurological diseases.
“Two important negative findings are related to Parkinsonism and Guilin-Barr syndrome,” Dockett said. ‘We know that both conditions are neurological conditions, which are sometimes associated with viral infections. We did not find them to be very common after COVID-19 and other respiratory infections we analyzed.
According to Dr. Musa Sami, Associate Medical Professor of Psychiatry at the University of Nottingham, the study was important because the researchers were able to analyze the large number of patient records.
“This is solid work in a large group that demonstrates the link between COVID-19 and mental and neurological problems,” he said in a statement. “This is a very important issue because there is considerable confusion as to whether Covit-19 is a ‘brain disease’.”
Sami, unrelated to the study, pointed out the need for further research on how COVID-19 affects the brain and nervous system. “Psychological stress, long hospital stays and the symptoms of the disease may play a role,” he said.
A Tip: Masood Hussein, a professor of neuroscience and cognitive science at Oxford University and co-author of the study, says that psychological symptoms are more common than severe neurological problems.
“In fact, only those with the most serious illnesses are at risk of developing neurological problems, unlike the ones we see with mental health problems, which are very serious on board,” he said.
Other small studies have pointed to a similar result. A study in February found that 381 patients were treated for COVID-19 at a hospital in Rome, Italy, and that 30% of them experienced post-traumatic stress disorder after recovery.
Neurology: A December study in the journal Clinical Practice showed that COVID-19 can cause seizures and motor disorders, even in mild cases.
The long-term burden of Govt-19 on the health system
One limitation of the Lancet psychiatric study is that it uses “regular health care data” rather than research data, says Paul Harrison, professor of psychiatry at the University of Oxford and head of the study.
Which means diagnoses are missing, not fully investigated, or misleading.
Diagnosis can make a difference.
“Patients with COVID-19 are more likely to have neurological and psychiatric diagnoses because they received more follow-up and more clinical care compared to patients with respiratory tract infections. This may explain some of the differences we have seen in rates,” Dockett told a news conference.
But still, this study provides a broader perspective on the long-term burden on those affected by the epidemic.
“While the individual risks for most disorders are small, the impact on the general population as a whole due to the extent of the infection and the chronic nature of these conditions can be significant for health and social care systems.”
