• Abstract: Recent advancements in generative AI have flourished the development of highly adept Large Language Models (LLMs) that integrate diverse data types to empower decision-making. Among these, Multimodal Retrieval-Augmented Generation (RAG) applications are promising for their capability to combine the strengths of information retrieval and generative models, enhancing their utility across various domains, including biomedical research. This paper introduces AlzheimerRAG, a Multimodal RAG pipeline tool for biomedical research use cases, primarily focusing on Alzheimer's disease from PubMed articles. Our pipeline incorporates multimodal fusion techniques to integrate textual and visual data processing by efficiently indexing and accessing vast amounts of biomedical literature. Preliminary experimental results against benchmarks, such as BioASQ and PubMedQA, have returned improved results in information retrieval and synthesis of domain-specific information. We also demonstrate a case study with our RAG pipeline across different Alzheimer's clinical scenarios. We infer that AlzheimerRAG can generate responses with accuracy non-inferior to humans and with low rates of hallucination. Overall, a reduction in cognitive task load is observed, which allows researchers to gain multimodal insights, improving understanding and treatment of Alzheimer's disease.

  Brain transcriptomics provides insights into the molecular mechanisms by which the brain coordinates its functions and processes. Existing multimodal methods for predicting Alzheimer's disease (AD) primarily rely on imaging and sometimes genetic data, often neglecting the transcriptomic basis of brain. Here, we propose TMM, a trusted multiview multimodal graph attention framework for AD diagnosis using extensive brain-wide transcriptomics and imaging data.
