Many of the neurological sequelae appear to result from damage to the vascular cells of the brain or from damage resulting from hypoxia (i.e., limitations in the oxygen supply for the brain). Chronic effects of COVID-19 can lead to a prolonged inflammatory state, which can increase symptoms resembling an autoimmune disorder. [ 1 ]
A study looking at ultra-detailed MRI scans of people hospitalized with severe COVID-19 found that the disease affects the brainstem, a region of the brain responsible for controlling many key ...
People who had COVID-19 are at higher risk for a host of brain injuries a year later compared with people who were never infected by the coronavirus, a finding that could affect millions of ...

An overall definition of post-COVID conditions (PCC) can be described as a range of symptoms that can last for weeks or months. [83]
Studies suggest that COVID-19 is associated with possibly long-lasting changes to the brain, potentially contributing to cognitive problems like brain fog, mental fatigue, and memory loss, as well ...
COVID-19’s link to declines in the smell-related brain regions, Douaud said, does not discount the other ways that it might impact the brain in regions unrelated to smell.
Hypogeusia can be defined as the reduced ability to taste things. [1] Due to a lack of stratification, the prevalence of hypogeusia, as well as hyposmia , may not be accurately known. [ 2 ] Additionally, reviews do not always make distinctions between ageusia and hypogeusia, often classifying them as the same in certain circumstances and ...
