New evidence indicates that individuals who have survived infections with COVID-19 are at increased risk of contracting the psychiatric disease. These results reported in The Lancet Psychiatry Journal suggest that 18 percent of COVID-19 patients are hospitalized with psychological symptoms of anxiety, depression, or insomnia within ninety days of diagnosis.

Researchers studied data from around 69 million individuals, 62,354 of whom were COVID-19 patients, to see whether they were at a greater risk of psychiatric diagnosis after infection than people with other health problems. The findings indicate that people with COVID-19 have more post-illness diagnosis with depressive disorder, insomnia, and even dementia than those with influenza or other respiratory illnesses related to COVID-19.

Anxiety symptoms are the most prevalent condition after illness, with dementia arising only in individuals older than 65 years of age.
