The findings, published in the journal 'Brain, Behavior and Immunity', emphasizes the need for special care for populations with these pre-existing conditions during the pandemic. Researchers have claimed that dementia and other cognitive disorders now appear to be the risk factors for developing severe COVID-19.
“We took a hypothesis-free approach and the most statistically significant ones are the cognitive disorders and Type-2 diabetes,” said study senior author Kaixiong Ye from the University of Georgia in the US. He adds; “Right now, we don’t know the mechanisms behind these associations, we only know these are more common in COVID-19 patients.”
The research team also found that variations in genes related to SARS-CoV-2 infection may be associated with severe Covid-19 that requires hospitalization.
In a blind study, the researchers analyzed data from about 1,000 diseases and two specific genes to compare the health profiles of Covid patients with those testing negative, looking for commonalities in the patients.
