Association between autoimmune diseases and Alzheimer's disease: analysis using big data tools.

Area of Science:

• Neuroscience
• Immunology
• Epidemiology

Background:

• Alzheimer's disease (AD) is a progressive neurodegenerative disorder.
• Autoimmune diseases involve the immune system mistakenly attacking the body's own tissues.
• The potential connection between autoimmune conditions and AD requires further investigation.

Purpose of the Study:

• To determine the prevalence of Alzheimer's disease in patients with various autoimmune diseases.
• To explore the association between Alzheimer's disease and specific autoimmune pathologies.

Main Methods:

• A multicenter, retrospective cohort study analyzed electronic medical records.
• Natural Language Processing (NLP) and artificial intelligence (AI) were used for data analysis.
• Over one million patients were included, with a comparison between those with and without Alzheimer's disease and autoimmune diagnoses.

Main Results:

• Five out of twelve analyzed autoimmune diseases demonstrated a significant association with Alzheimer's disease (p < 0.05).
• Conditions such as myasthenia gravis, systemic lupus erythematosus, rheumatoid arthritis, polymyalgia rheumatica, and pernicious anemia showed increased AD prevalence.
• Odds ratios ranged from 1.38 to 2.42 for these associated conditions.

Conclusions:

• A potential association exists between certain systemic autoimmune diseases and Alzheimer's disease.
• Further research is necessary to confirm these findings, establish causality, and elucidate underlying mechanisms.
• Understanding this link could offer new insights into AD pathogenesis and treatment.
