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.
The authors also analyzed the brain structure of 26 people who died of Covid-19 infection and found that samples from five of these individuals exhibited tissue damage.
