People recovering from COVID-19 may suffer from significant brain function impacts, with the worst cases of the infection linked to mental decline equivalent to the brain ageing by 10 years, researchers warn reut.rs/2TwAeWs 1/5 
A non-peer-reviewed study of more than 84,000 people, led by Adam Hampshire, a doctor at Imperial College London, found that in some severe cases, coronavirus infection is linked to substantial cognitive deficits for months 2/5
Cognitive tests measure how well the brain performs tasks - such as remembering words or joining dots on a puzzle. Such tests are widely used to assess brain performance in diseases like Alzheimer’s, and can also help doctors assess temporary brain impairments 3/5
The cognitive deficits were 'of substantial effect size,' particularly among people who had been hospitalized with COVID-19, researchers said, with the worst cases showing impacts 'equivalent to the average 10-year decline in global performance between the ages of 20 to 70' 4/5
Scientists not directly involved with the study, however, said its results should be viewed with some caution. Read the full story here: reut.rs/3dZoLbn by @kkelland 5/5
