This focuses on the use of lithium for treating psychiatric disorders, as a mood stabilizer. However, in addition to this, there is lots of evidence[1][2] that trace amounts of lithium in general populations lead to lower rates of violent crime (and has general neuroprotective effects). I think this connection makes sense logically, if large doses serve to stabilize the mood of bipolar patients, small doses would likely have at least some effect on 'regular' people. It is possible to buy trace mineral drops which contain such small amounts of lithium as to be safe for everyday use (as a bonus they also contain other useful trace minerals, like magnesium). I personally have been using them for years.
