Seven in 10 COVID survivors have memory and concentration problems Seven in 10 long-term COVID patients experience problems with concentration and memory months after diagnosis, according to a new study from the University of Cambridge. Moreover, many of them show worse results than their peers in cognitive tests..

In a study of 181 patients with long-term COVID, 78% reported difficulty concentrating, 69% brain fog, 68% forgetfulness, and 60% problems finding the right word when speaking.. These self-reported symptoms were reflected in a significantly lower ability to remember words and images on cognitive tests..

Participants completed several tasks to assess their memory and decision-making ability.. These include remembering the words in the list and which two images appear together.. Findings reveal a consistent pattern of ongoing memory problems in those who have had a COVID-19 infection. Problems were more pronounced in people whose course of the disease was more severe.

In order to understand the cause of cognitive problems, scientists investigated other symptoms that may be associated with them..

They found that people who had fatigue and neurological symptoms at the start of the infection were more likely to experience cognitive difficulties later on.. They also found that those who still experienced neurological symptoms performed especially poorly on cognitive tests..

Dr Muzaffer Kaser from the Faculty of Psychiatry at the University of Cambridge emphasizes that these data prove that cognitive problems after COVID are not always associated with anxiety or depression..
