Texas: Study of 10 years showing that the incidence rates of suicide, homicide, and rape are significantly higher in counties whose drinking water supplies contain little or no lithium than in counties with water that has lithium
Another study showing chronic lithium users exhibit larger hippocampal volumes relative to their peers who are either unmedicated or undergoing other forms of treatment. This suggests that lithium treatment may normalize hippocampal volume reductions observed in psychiatric disorder patients, either by protecting existing neurons or by promoting neurogenesis (neurone regeneration)
The hippocampus is a brain area which regulates learning, memory, cognition, and mood, and large mega-analyses from the ENIGMA neuroimaging consortium suggest smaller hippocampal volumes are a common feature amongst psychiatric disorder patients
