This research aims to investigate the relationship between lithium levels in groundwater and stroke incidence and mortality rates.
Analyzed lithium concentrations in US groundwater samples.
Correlated lithium levels with stroke incidence and mortality data across regions.
Identified low to moderate lithium levels as not beneficial.
Higher lithium concentrations are linked to lower stroke incidence rates.
Increased lithium exposure correlates with reduced stroke mortality.
Low to moderate lithium levels showed no beneficial effects on stroke outcomes.
Abstract
Higher naturally occurring lithium concentrations in US groundwater are associated with reduced stroke mortality and incidence, whereas low to moderate levels confer no benefit.
