One in five COVID-19 patients develop mental illness within 90 days: Study

LONDON: COVID-19 survivors are likely to be at greater risk of developing mental illness as a large study found 20 percent of those infected with the coronavirus are diagnosed with a psychiatric disorder within 90 days.

Anxiety, depression and insomnia were most common among recovered COVID-19 patients who developed mental health problems and researchers also found significantly higher risks of dementia, a brain impairment condition.

“People have been worried that COVID-19 survivors will be at greater risk of mental health problems, and our findings show this to be likely,” said Paul Harrison, a professor of psychiatry at Oxford University.

Doctors and scientists around the world urgently need to investigate the causes and identify new treatments for mental illness after COVID-19, Harrison said. “(Health) services need to be ready to provide care, especially since our results are likely to be underestimates (of the number of psychiatric patients),” he added.

The study, published in The Lancet Psychiatry journal, analysed electronic health records of 69 million people in the United States, including more than 62,000 cases of COVID-19.

In the three months following testing positive for COVID-19, one in five survivors were recorded as having a first time diagnosis of anxiety, depression or insomnia.

Researchers said this was about twice as likely as for other groups of patients in the same period. The study also found that people with a pre-existing mental illness were 65 percent more likely to be diagnosed with COVID-19 than those without.

Mental health specialists not directly involved with the study said its findings add to growing evidence that COVID-19 can affect the brain and mind, increasing the risk of a range of psychiatric illnesses.

Michael Bloomfield, a consultant psychiatrist at University College London, said this is likely due to a combination of the psychological stressors associated with this particular pandemic and the physical effects of the illness,

Simon Wessely, regius professor of psychiatry at King’s College London, said the finding that those with mental health disorders are also at higher risk of getting COVID-19 echoed similar findings in previous infectious disease outbreaks.

“COVID-19 affects the central nervous system, and so might directly increase subsequent disorders. But this research confirms that is not the whole story, and that this risk is increased by previous ill health,” he said.
