MedExpMem: Adapting Experience Memory for Differential Diagnosis

arXiv:2605.22872v1 Announce Type: new Abstract: Experienced physicians develop diagnostic expertise through clinical practice, acquiring not only disease knowledge but also the ability to differentiate confusable conditions. Current medical vision-language models (VLMs) lack this capability -- their parameters encode static knowledge that does not evolve across diagnostic encounters. We propose MedExpMem, an experience memory framework enabling VLM-based diagnostic agents to accumulate differential diagnosis expertise. Unlike retrieval-augmented generation, which retrieves encyclopedic disease

Why this matters
Why now

The rapid advancement of AI in medicine, particularly vision-language models, necessitates new approaches to bridge the gap between static AI knowledge and dynamic human diagnostic expertise.

Why it’s important

This development indicates progress towards more capable and adaptable AI systems in critical fields like healthcare, potentially enhancing diagnostic accuracy and efficiency.

What changes

AI models for medical diagnosis are evolving beyond mere knowledge retrieval to incorporate cumulative experience and differential diagnostic reasoning, mirroring human clinical development.
