Quantum simulations explore lithium isotopes in bipolar disorder treatment

University of Surrey researchers are investigating whether the therapeutic effects of lithium for bipolar disorder are linked to "nuclear spin," a quantum property of atomic nuclei. Published in PLOS ONE, the study used computational chemistry to model how lithium-6 and lithium-7 isotopes interact with brain-relevant molecules like vitamin B2-derived flavin and vitamin C radicals.

Simulations suggest these isotopes may influence biological reactions differently due to their distinct nuclear spins. The predicted effects align with previous animal studies showing behavioral differences between the two isotopes. While not yet experimentally confirmed in human brains, these findings could potentially lead to new treatment designs by fine-tuning medicinal isotopic composition.
