Summary: A new study has discovered that ophthalmic acid, a molecule in the brain, acts like a neurotransmitter to regulate motor function, similar to dopamine. In Parkinson’s mouse models, this molecule improved movement for over 20 hours—far longer than the effects of the current treatment, L-dopa.
This finding challenges the long-held belief that dopamine is the only key player in motor control. Researchers are now exploring how to use ophthalmic acid as a potential treatment for movement disorders, offering hope for more effective therapies.
