Furthermore, a recent study found one seventh of patients have problems remembering and learning new tasks as well as problems with concentrating and decision making 12 weeks after infection.
Speaking about the results of the study, the University of Cambridge’s Professor David Menon said: “Cognitive impairment is common to a wide range of neurological disorders, including dementia, and even routine ageing, but the patterns we saw – the cognitive ‘fingerprint’ of COVID-19 – was distinct from all of these.”
Professor Menon added such as the impact on the brain of Covid that “some of these individuals will never fully recover”.
Researchers said several factors could cause cognitive deficits including inadequate blood oxygen supply to the brain.
