Lithium: The Gift That Keeps on Giving in Psychiatry

At the recent American Psychiatric Association annual meeting in San Diego, an update symposium was presented on the topic of "Lithium: Key Issues for Practice." In a session chaired by Dr David Osser, associate professor of psychiatry at Harvard Medical School, presenters reviewed various aspects of the utility of lithium in psychiatry.

Leonardo Tondo, MD, a prominent researcher on lithium and affective illness, who is on the faculty of McLean Hospital/Harvard Medical School and the University of Cagliari, Italy, reviewed studies on lithium's effects for suicide prevention. Ecological studies in this field have found an association between higher amounts of lithium in the drinking water and lower suicide rates.


These "high" amounts of lithium are equivalent to about 1 mg/d of elemental lithium or somewhat more. Conversely, other studies did not find such an association, but tended to look at areas where lithium levels are not high (ie, about 0.5 mg/d of elemental lithium or less). Nonetheless, because these studies are observational, causal relationships cannot be assumed. It is relevant, though, that lithium has been causally associated with lower suicide rates in randomized clinical trials of affective illness, compared with placebo, at standard doses (around 600-1200 mg/d of lithium carbonate).

Many shy away from Lithium not knowing that not prescribing it may actually lead to death by suicide. As such all worries about long term side effects become meaningless. 


Will the new generation of psychiatrists come round to Lithium again? How many talented individuals could have been saved by lithium?

  • In psychiatry, our most effective drugs are the old drugs: ECT (1930s), lithium (1950s), MAOIs and TCAs (1950s and 1960s) and clozapine (1970s)
    • We haven’t developed a drug that’s more effective than any other drug since the 1970’s
    • All we have developed is safer drugs (less side effects), but not more effective
  • Dose lithium only once a day, at night
  • For patients with bipolar illness, you don’t need a reason to give lithium. You need a reason not to give lithium  (Originally by Dr. Frederick K. Goodwin)


Lithium in Tap Water and Suicide Mortality in Japan.

Abstract: Lithium has been used as a mood-stabilizing drug in people with mood disorders. Previous studies have shown that highest levels of suicide mortality rate in Japan. Lithium levels in the tap water supplies of each municipality were measured using natural levels of lithium in drinking water may protect against suicide. This study evaluated the association between lithium levels in tap water and the suicide standardized mortality ratio (SMR) in 40 municipalities of Aomori prefecture, which has the inductively coupled plasma-mass spectrometry. After adjusting for confounders, a statistical trend toward significance was found for the relationship between lithium levels and the average SMR among females. These findings indicate that natural levels of lithium in drinking water might have a protective effect on the risk of suicide among females. Future research is warranted to confirm this association.



"Many psychiatric residents have no or limited experience prescribing lithium, largely a reflection of the enormous focus on the newer drugs in educational programs supported by the pharmaceutical industry."

One might ask why there has been such a shift from Lithium.

Could it be the simplicity of the salt that is causing problems for the younger generation of psychiatrists brought up on various neuro-transmitters?

Could it be the fact that 
Lithium was discovered in Australia? Look at the time it took for Helicobacter pylori to be accepted.

Some felt it has to do with how little money is to be made from Lithium.
