Microbial links to Alzheimer's disease

Area of Science:

• Neuroscience
• Pathology
• Infectious Diseases

Background:

• Alzheimer's disease (AD) is a neurodegenerative disorder characterized by plaques, neuronal death, tau hyperphosphorylation, and memory loss.
• The precise cause of AD remains elusive despite extensive research.
• Decades of evidence suggest a potential link between infectious pathogens and AD etiology.

Purpose of the Study:

• To review the current understanding of the role of infectious pathogens in Alzheimer's disease (AD).
• To explore the correlations between microbial presence and AD pathologies.
• To discuss whether infections are causative agents or contributing factors to AD progression.

Main Methods:

• This mini-review synthesizes existing research on the topic.
• It examines documented correlations between microbes (bacteria, viruses, fungi) and AD.
• The review discusses the potential direct role of pathogens in triggering or exacerbating AD.

Main Results:

• Notable correlations exist between various microbes and AD pathologies.
• Pathogens may not be the sole cause but could contribute to AD development or worsening.
• The role of infections in AD pathogenesis warrants significant consideration.

Conclusions:

• The involvement of infectious agents in Alzheimer's disease (AD) etiology is a significant area of investigation.
• While not definitively causative, microbes may directly influence AD progression.
• Further research is crucial to elucidate the precise role of infections in AD pathogenesis.
