April 9 – 12, 2027
AANS Annual Scientific Meeting in San Diego
The theme of the 2027 AANS Annual Scientific Meeting, Navigating the Impossible, reflects a defining truth of neurosurgery. Every day, neurosurgeons confront complexity and uncertainty, testing the boundaries of what is known and what is possible.
More than a technical challenge, the specialty captures the human spirit of practice by advancing innovation and translating discovery into care. It requires a unique blend of expertise and intuition, especially when making critical decisions in moments where the path forward is not clearly defined
Through groundbreaking science and shared experience, we will explore how neurosurgeons push past limitations and redefine what is achievable for patients.
Join us in San Diego as we navigate the impossible together.

Ripple Effect
Ripple Effect
#AANS2025 celebrates the transformative power of individual actions and their potential to create widespread impact within and beyond the neurosurgical community through the 2025 AANS Annual Scientific Meeting’s social media campaign: #aansRippleEffect.
What is the Ripple Effect?
The Ripple Effect embodies the idea that a single action can spark a series of events, much like a drop of water creating ripples in a pond. Our theme for #AANS2025, “Power of One, Impact of Many,” highlights how individual contributions can drive significant change across various facets of our field. Every neurosurgeon holds the potential to transform lives with each decision, procedure, and interaction. The impact of a single innovative technique or a breakthrough in research can resonate throughout our community, enhancing patient outcomes and advancing our understanding of neurological disorders.
