There are certain mechanisms by which SARS-CoV-2, the virus that causes Covid-19, can result in dementia similar to Alzheimer's disease, according to a new study.

In an attempt to study how the virus causes neurological issues, researchers from the Cleveland Clinic in the US used artificial intelligence (AI) and incorporated existing datasets of patients with Alzheimer's and Covid-19. They then measured the proximity between the virus' host genes (proteins) and those linked with several neurological diseases, where closer proximity suggested related or shared disease pathways.

They found little evidence that the virus targeted the brain directly but discovered something deeply concerning: there were close network relationships between the virus and proteins associated with several neurological diseases (most notably Alzheimer's).
