Long COVID is associated with severe cognitive slowing: a multicentre cross-sectional study

Persistent Cognitive Impairments Found in Long COVID Cases, Independent of Mental Health Factors
"This might be an important factor contributing to some of the cognitive impairments reported in patients with PCC," said researchers from the University of Oxford. To examine cognitive slowing, patients with PCC completed two short web-based cognitive tasks, Simple Reaction Time (SRT) and Number Vigilance Test (NVT). About 270 patients diagnosed with PCC at two different clinics in the UK and Germany were compared to two control groups -- individuals who contracted COVID-19 before but did not experience PCC after recovery (No-PCC group) and uninfected individuals (No-COVID group).

The results showed cognitive slowing was evident even on a 30-sec task measuring SRT, with patients with PCC responding to stimuli about 3 standard deviations slower than healthy controls. About 54 percent of patients with PCC's response speed was slower than 2 standard deviations from the control mean, indicating a high prevalence of cognitive slowing in PCC. Comorbidities such as fatigue, depression, anxiety, sleep disturbance, and post-traumatic stress disorder did not account for the extent of cognitive slowing in patients with PCC. Furthermore, cognitive slowing on the SRT was highly correlated with the poor performance of patients with PCC on the NVT measure of sustained attention.
There was not a significant correlation between the severity of mental health symptoms and chronic post-COVID cognitive deficit. "The present study reported a significant psychomotor slowing in individuals diagnosed with PCC," the authors said. "This might be an important factor contributing to some of the cognitive impairments reported in patients with PCC."

Coronaviruses infect animals, humans, and birds. Human coronaviruses, such as SARS, MERS, and 2019-nCoV cause respiratory distress and even death. The S protein is the infectious agent of the virus.

Long COVID Smell Loss is Linked to Changes in Brain Activity
Long COVID anosmia shows different patterns of activity in certain regions of the brain. This may impair communication between brain regions that are related to the sense of smell.
