Lithium In Water "Curbs Suicide"
SpuriousLogic writes "Drinking water which contains lithium may reduce the risk of suicide, a Japanese study suggests. Researchers compared levels of lithium in drinking water to suicide rates in the prefecture of Oita, which has a population of more than one million. The suicide rate was significantly lower in those areas with the highest levels of lithium, they wrote in the British Journal of Psychiatry. And I was only worried about fluoridation affecting my precious bodily fluids before ..."
Manic episodes are definitely not "irrationally and exceptionally happy" and are very often extremely unpleasant.
Lithium acts as a mood stabilizer and works on both depression and mania.
The post you replied to is exactly right. In places with a mood stabilizing chemical in the water, suicide rates are lower. Fairly unsurprising except that the amount of lithium being dealt with is probably well below the known therapeutic threshold.
I don't think anyone's saying anything about scientists PUTTING lithium into the water. They went around and measured levels of lithium already in the water and found that the areas with higher levels had less suicides. Seems like other factors could be at play here too, considering that geographic areas are often different from one another in many societal aspects.

Raynaud's phenomenon
diabetes insipidus
It can also cause thyroid problems and kidney failure. Patients must undergo very stringent tests to see if their body can cope with lithium, before it is given to them.
The problem is, lithium is highly toxic only very slightly above the theraputic threshold, making it extremely dangerous. Failure to drink, or sweating too much, will cause the lithium concentration to become dangerous or possibly deadly.
Well, that's -a- problem. Another is that it massively reduces the seizure threshold, so anyone potentially subject to seizures must also be put on anti-seizure medication to cancel the side-effect or risk having their brain turn into swiss cheese. However, each time you add medicines, you add risk of an abreaction to the new medication and also risk of the medications interacting in harmful ways.
(Many who die of medications they were prescribed die because the medications interacted.)
Despite Lithium being one of the longest-used medications for mental healthcare, it is still not very well understood. Patients are tried on it to see if it'll work for them, because it works much of the time. If it doesn't work, the doctor will try something else at random, and keep on going until something does work.
Why there haven't been studies using Lithium isotopes to trace the effects and identify the specific class(es) of condition(s) Lithium can deal with and which it can't, I don't know. It would seem easy enough and it would reduce the randomness in the mental healthcare industry.

Lithium is the third element in the periodic table, and the first metal. In other words, it is as far from being a heavy metal as it is possible to get.

For those that do not know, lithium is a commonly prescribed medication for people with bipolar/manic depression disorder. Suicide is the only top 10-20 killer among all age groups in the US. The people most likely to commit suicide are bipolar people as opposed to people who are "normal" or those with other psychiatric disorders (major/minor depression, schizophrenia, etc). Similar studies to the one in this story have been done in Texas where lithium levels in the water supply are significantly above average compared to other states and the hospitalizations and suicide rate of bipolar people are less in Texas than other states. Yes, these studies are correlational, but anyone with a basic knowledge of statistics knows that correlation is well beyond the mantra shouted here that "correlation != causation".
Case in point with Nirvana's Lithium lyrics, the author of the song, Kurt Cobain, was bipolar, and he is now dead from suicide. The reason suicide is so common with bipolar people is because it is so difficult for them to handle the swings from the feelings of mania and euphoria down to the feelings of worthlessness and despair. Also, heavy substance abuse, particularly with central nervous system depressants like alcohol and heroin are common among bipolar people because they temporarily relieve stress (a trigger for instability) and well alcohol and heroin are quite pleasant drugs to do in the first place. Its not uncommon for them to semi-regularly do drugs like cocaine, MDMA, or LSD to bring back the familiar feelings of mania and euphoria.
Its common for the drug use or other unconventional social behaviors to be incorrectly deemed as causal towards the feelings and behaviors of people with bipolar disorder. I know someone very well who has bipolar disorder who has gone back and forth between a highly functional, well educated, intelligent, middle-class professional to chronic alcoholism, homelessness, in and out of jail and unemployment, to back again to the functional part. In our society, its not very permitted for people to take weeks, months or years away from activities like work or school which is what most people do from 5-65 years of age, and any and all deviations from consistency are heavily punished due to lower pay, lack of promotions, loss of jobs, jail, hospitalization, etc, which is enough to make any "normal" person depressed.
