One third of COVID survivors suffer neurological or mental disorders: study

One in three COVID-19 survivors, in a study of more than 230,000 mostly American patients, were diagnosed with a brain or psychiatric disorder within six months, suggesting the pandemic could lead to a wave of mental and neurological problems, scientists said on Tuesday.

Researchers who conducted the analysis said it was not clear how the virus was linked to psychiatric conditions such as anxiety and depression, but that these were the most common diagnoses among the 14 disorders they looked at, Reuters reported.

Post-COVID cases of stroke, dementia and other neurological disorders were rarer, the researchers said, but were still significant, especially in those who had severe COVID-19.

“Our results indicate that brain diseases and psychiatric disorders are more common after COVID-19 than after flu or other respiratory infections,” said Max Taquet, a psychiatrist at Britain’s Oxford University, who co-led the work.

Reuters reported the study was not able to determine the biological or psychological mechanisms involved, he said, but urgent research is needed to identify these “with a view to preventing or treating them”.

Health experts are increasingly concerned by evidence of higher risks of brain and mental health disorders among COVID-19 survivors. A previous study by the same researchers found last year that 20 percent of COVID-19 survivors were diagnosed with a psychiatric disorder within three months.

The new findings, published in the Lancet Psychiatry journal, analysed health records of 236,379 COVID-19 patients, mostly from the United States, and found 34 percent had been diagnosed with neurological or psychiatric illnesses within six months.

The disorders were significantly more common in COVID-19 patients than in comparison groups of people who recovered from flu or other respiratory infections over the same time period, the scientists said, suggesting COVID-19 had a specific impact.

Anxiety, at 17 percent, and mood disorders, at 14 percent, were the most common, and did not appear to be related to how mild or severe the patient’s COVID-19 infection had been.

Among those who had been admitted to intensive care with severe COVID-19 however, seven percent had a stroke within six months, and almost two percent were diagnosed with dementia.

“Although the individual risks for most disorders are small, the effect across the whole population may be substantial,” said Paul Harrison, an Oxford psychiatry professor who co-led the work.

WHO declares end to COVID global health emergency

The World Health Organization said Friday that COVID-19 no longer qualifies as a global emergency, marking a symbolic end to the devastating coronavirus pandemic that triggered once-unthinkable lockdowns, upended economies and killed millions of people worldwide.

The announcement, made more than three years after WHO declared the coronavirus an international crisis, offers some relief, if not an ending, to a pandemic that stirred fear and suspicion, hand-wringing and finger-pointing across the globe, AP reported. 

The U.N. health agency’s officials said that even though the emergency phase was over, the pandemic hasn’t finished, noting recent spikes in cases in Southeast Asia and the Middle East.

WHO says thousands of people are still dying from the virus every week, and millions of others are suffering from debilitating, long-term effects.

“It’s with great hope that I declare COVID-19 over as a global health emergency,” WHO Director-General Tedros Adhanom Ghebreyesus said.

“That does not mean COVID-19 is over as a global health threat,” he said, warning that new variants could yet emerge. Tedros noted that while the official COVID-19 death toll was 7 million, the real figure was estimated to be at least 20 million.

Tedros said the pandemic had been on a downward trend for more than a year, acknowledging that most countries have already returned to life before COVID-19.

He bemoaned the damage that COVID-19 had done to the global community, saying the pandemic had shattered businesses, exacerbated political divisions, led to the spread of misinformation and plunged millions into poverty.

When the U.N. health agency first declared the coronavirus to be an international crisis on Jan. 30, 2020, it hadn’t yet been named COVID-19 and there were no major outbreaks beyond China.

More than three years later, the virus has caused an estimated 764 million cases globally and about 5 billion people have received at least one dose of vaccine.

In the U.S., the public health emergency declaration made regarding COVID-19 is set to expire on May 11, when wide-ranging measures to support the pandemic response, including vaccine mandates, will end. Many other countries, including Germany, France and Britain, dropped most of their provisions against the pandemic last year.

When Tedros declared COVID-19 to be an emergency in 2020, he said his greatest fear was the virus’ potential to spread in countries with weak health systems.

Most recently, WHO has struggled to investigate the origins of the coronavirus, a challenging scientific endeavor that has also become politically fraught.

China says 200 million treated, pandemic ‘decisively’ beaten

China says more than 200 million of its citizens have been diagnosed and treated for COVID-19 since it lifted strict containment measures beginning in November.

With 800,000 of the most critically ill patients having recovered, China has “decisively beaten” the pandemic, according to notes from a meeting of the ruling Communist Party’s all-powerful Politburo Standing Committee presided over by President and party leader Xi Jinping, AP reported. 

China enforced some of the world’s most draconian lockdowns, quarantines and travel restrictions and still faces questions about the origins of the virus that was first detected in the central Chinese city of Wuhan in late 2019. Heavy-handed enforcement prompted rare anti-government protests and took a heavy toll on the world’s second-largest economy.

The official Xinhua News Agency quoted Xi as saying that policies to control the outbreak had been “entirely correct.” The abrupt lifting in November and December of the “zero COVID” policy that had sought to eliminate all cases of the virus led to a surge in infections that temporarily overwhelmed hospitals.

Case numbers have since peaked and life has largely returned to normal, although international travel in and out of China has yet to return to pre-pandemic levels.

China is now transitioning to a post-pandemic stage after a fight against the outbreak that was “extraordinary in the extreme,” Xinhua said.

The government will continue to “optimize and adjust prevention and control policies and measures according to the times and situations with a strong historical responsibility and strong strategic determination,” Xinhua said.
