The Society of Nuclear Medicine and Molecular Imaging shows how COVID-19 causes long-term neurological changes associated with cognitive impairment. Researchers compared PET-scans of hospitalized COVID-19 patients with cognitive impairment before and after their recovery.
It has become increasingly clear that neurocognitive long-term consequences occur during severe, moderate and even mild cases of COVID-19. In the images taken on the brain of those suffering from neurocognitive effects of COVID-19 showed positive weights in brain stem, cerebellum, white matter and mesial temporal structures.
As a result of the study, the authors suggest post-COVID-19 patients with persistent cognitive effects should seek help from a neurologist and rehabilitation center. That COVID-19 does cause neurological issues regardless of how severe a COVID-19 case is.
