Higher lithium exposure in groundwater is associated with reduced stroke incidence and mortality.

Key Points

• 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.
