Unraveling the Effects of SARS-CoV-2 on Dementia: A Comprehensive Study

Since late 2019, a pandemic caused by SARS-CoV-2, a highly contagious coronavirus, has jeopardized human and public health. Neurodegeneration and structural brain diseases produce dementia, which is developing rapidly. Strong evidence of COVID-19 brain abnormalities as neurotrophic viruses impair neurological systems. Neuron and glial cell degeneration can affect nerve transmission and brain function. Damage to these brain components raises dementia risk. Multiple studies linked SARS-CoV-2 to dementia. This manuscript contains selective data. This study aims to review the findings and suggest strategies to improve SARS-COVID dementia management. The study makes use of medical research databases like Google Scholar, PubMed, Medline, and Embase. Furthermore, information is also collected by recognized health organizations and government agencies. COVID-19 can produce neuropsychological deficits, agitation, confusion, inattention, and disorientation. Thus, SARS can worsen dementia and neurodegeneration. This article summarizes COVID-19's effects on dementia patients from several sources. The focus on existing treatments for affected patients ties the two.
