Summary
This review examines how the neuropeptide CGRP modulates sensory sensitivity in migraine, including heightened responses to light (photophobia), through peripheral and central nervous system mechanisms. For lighting designers and healthcare environments, this highlights the importance of controlling light intensity and spectral qualities in spaces serving migraine-prone populations.
Key Findings
- CGRP receptor antagonists have demonstrated clinical efficacy in treating migraine, establishing CGRP as a validated therapeutic target.
- CGRP enhances sensitivity to sensory input — including light — at multiple levels of the nervous system, providing a mechanistic basis for migraine-associated photophobia.
- Antibodies targeting CGRP or its receptor are under active clinical investigation as migraine preventatives, suggesting that light-triggered migraine may be addressable through this pathway.
