ANI says that infection with SARS-COV-2 can cause brain alterations and neurocognitive dysfunction, particularly in long Covid-19, but the underlying mechanisms are elusive.
Daniel Martins-de-Souza and colleagues conducted MRI of 81 study participants recovering from mild Covid-19 infection and 81 healthy individuals to compare their brain structure.
It was found that the former group exhibited reduced cortical thickness, which was correlated with cognitive impairments and symptoms such as anxiety and depression.
