Severe Covid May Cost Survivors 10 IQ Points, Study Finds

Severe Covid-19 may cause long-lasting cognitive impairment, similar to how much brainpower 70-year-olds typically have lost compared to age 50, a new study found, adding to preliminary evidence that infections may inhibit survivors’ intellectual capabilities.

The study of 46 patients, who were assessed six to ten months after being hospitalized, showed slower and less accurate responses than what was expected for their age and demographic profile. Those patients who required ventilators and organ support scored even worse. The effect was sudden, as it was the equivalent of aging 20 years intellectually within the span of a few months.
