COVID-19 and Alzheimer's Disease

Area of Science:

• Neuroscience
• Infectious Diseases
• Gerontology

Background:

• Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) exhibits neurotropic properties and significant neuroinvasive potential.
• Neurological symptoms are common in COVID-19 patients, yet long-term neurological consequences remain understudied.
• A potential bidirectional relationship exists between Alzheimer's Disease (AD) and COVID-19.

Purpose of the Study:

• To review the intricate relationship between Alzheimer's Disease (AD) and COVID-19.
• To explore the mechanisms linking SARS-CoV-2 infection to neurodegeneration.
• To highlight the role of biomarkers in identifying COVID-19 patients at elevated risk for AD.

Main Methods:

• Literature review of existing studies on SARS-CoV-2, neurological manifestations, and Alzheimer's Disease.
• Analysis of proposed mechanisms for SARS-CoV-2-induced neurological injury.
• Discussion of the potential utility of biomarkers for early risk identification.

Main Results:

• SARS-CoV-2 infection is associated with an increased risk of developing Alzheimer's Disease.
• Alzheimer's Disease patients may exhibit heightened susceptibility to severe COVID-19.
• Biomarkers show promise for the early detection of individuals predisposed to AD post-COVID-19.

Conclusions:

• The interplay between COVID-19 and Alzheimer's Disease warrants further investigation.
• Early identification of at-risk individuals through biomarkers is crucial for timely intervention.
• Understanding this relationship can inform clinical management and future research directions.
