Lithium promotes
longevity, mood, and love

Lithium is a brain food, with extraordinary
properties, even in small amounts

By Will Block

L ithium has long been used as a mood stabilizer in the treatment of manic depression (known today as bipolar disorder). In fact, its first reported use was in 1949,1 when Dr. John Frederick Joseph Cade, an Australian psychiatrist, found that lithium carbonate operated as a mood enhancer in the treatment of manic depression disorder.

This was truly an important discovery because back then, the standard treatments for psychosis were electroshock therapy (a psychiatric treatment in which seizures are electrically induced in anesthetized patients for therapeutic effect) and lobotomy (a neurosurgical procedure, a form of psychosurgery, which consists of cutting the connections to and from the prefrontal cortex, the anterior part of the frontal lobes of the brain). Horrors! Lithium had the distinction of being the first effective medication available to treat a mental illness. Horrah!

Lithium decreases mortality

Last January, we reported on a lithium study that heralded one the great advances in longevity for 2011 (see “Longevity and the Future” in the January 2011 issue). Researchers from Germany and Japan analyzed the mortality rate in 18 adjacent Japanese municipalities in relation to the amount of the trace element lithium contained in tap water from the respective regions.2 “We found that the mortality rate was considerably lower in those municipalities with more lithium in the drinking water [bold added],” Professor Dr. Michael Ristow, the lead researcher explained.

Longer life from lithium

In other words, a regular small uptake of lithium can considerably promote longevity according to the researchers and that even a low concentration of lithium leads to an increased life expectancy in humans as well as in a model organism, the roundworm Caenorhabditis elegans. In a second experiment, the scientists examined exactly this range of low concentration in the C. elegans and were able to confirm: “The average longevity of the worms is higher after they have been treated with lithium at this dosage [bold added],” Ristow said. “From previous studies we know already that a higher uptake of lithium through drinking water is associated with an improvement of psychological well-being and with decreased suicide rates [bold added],” Professor Ristow continued. If you’re up for a long life, suicide is definitely a downer.

Lithium promotes the formation of new brain cells

Lithium is a brain food, with extraordinary properties, even in small amounts. As Durk Pearson & Sandy Shaw point out (see “Maintain your Brain the Durk Pearson & Sandy Shaw Way” in the May 2004 issue):

“One hundred to 150 years ago, we didn’t have the kind of mechanistic medicine that we do now, where we often know what’s going on down at the molecular level. There wasn’t much knowledge, even 100 years ago, about why things went wrong, but there was a lot of empirical knowledge—for example, that nitroglycerin could treat angina. [See “SUNY’s Nobel sage: NO is beautiful” on page 11.] That’s interesting, but it was only a decade ago that we finally learned why it works (it’s broken down to produce nitric oxide).

“In the case of lithium, the first clue that we got came from European health spas. Some mineral springs in Europe acquired the reputation of being able to rejuvenate old people: the springs made them feel better—made them function better—and improved their memories. They generally seemed to restore old people [bold added].”

Especially when they soaked in and drank the spa water for a month or two—long enough that something in the water might have an effect. The Vichy, France spa had a great reputation and its water is still bottled and sold all around the world. It contains 3.5 mg of lithium per liter according to Durk & Sandy’s findings and this, they suspect, is a beneficial amount. While it is a common belief that lithium must be taken at the level of hundreds of milligrams a day (which may be toxic at those amounts), the evidence continues to grow that it only takes a much smaller amount, say 7 mg/day, to have beneficial effects, and these effects continue to grow over time.

Lithium reduces violent crime

A study published in 1990, conducted over a 10-year period in 27 Texas counties, found that that the incidence rates of suicide, homicide, and rape were significantly higher in counties whose drinking water supplies contained little or no lithium than in counties with water lithium levels ranging from 70–170 micrograms/L.3 The researchers found that the people getting the higher levels of lithium had some beneficial mental effects, even after adjusting for socioeconomic factors, urbanization, etc.

The corresponding associations with the incidence rates of robbery, burglary, and theft were statistically significant. These results suggest that lithium has moderating effects on suicidal and violent criminal behavior at levels that may be encountered in municipal water supplies.

When differences in lithium consumption were taken into consideration in the Texas counties, the incidences of arrests for possession of opium, cocaine, and their derivatives (morphine, heroin, and codeine) also produced statistically significant inverse associations (less lithium = more arrests, etc.). However, there were no significant associations observed with the reported arrest rates for possession of marijuana, driving under the influence of alcohol, and drunkenness.

In the lithium group, the total positive
mood test scores increased steadily
during the four weeks of
supplementation and specifically in
the subcategories reflecting
happiness, friendliness, and energy.

Even low-dose lithium has mood-altering effects

Altogether, these results suggest that lithium at low dosage levels has a generally beneficial effect on human behavior, which may be associated with the functions of lithium as a nutritionally-essential trace element. The lead author, Dr. Gerhard N. Schrauzer, also published a review in which he stated that the available experimental evidence now appears to be sufficient to accept lithium as essential, with a provisional RDA for a 70 kg (150 pound) adult of 1 mg/day suggested.4*

* Dr. Schrauzer originally became interested in lithium after growing up next to a “miracle spring” in Franzensbad, Czechoslovakia. (See “SUNY’s Nobel sage: NO is beautiful” on page 11.)

Lithium may be good for Alzheimer’s

There have been papers demonstrating that lithium can lower the neurotoxicity of amyloid-beta, a major cause of Alzheimer’s disease but the doses have been in the toxicity zone. According to Durk & Sandy, “[W]e’re talking about prevention, where a very small change in toxicity over a long period of time can, like compound interest, plausibly produce some pretty big results years later. Also, researchers have found that lithium causes the release of neurotrophic factors that induce neurons to repair themselves and grow rather than die off when they’re under stress … such as brain-derived neurotrophic factor [BDNF], which is one of the most important for protecting neurons from damage and preventing them from dying. [bold added]”5 The same authors have thereafter reported that BDNF plays a critical role in the pathophysiology of mood disorders and in the activity of therapeutic agents in patients with mood disorders.6

Lithium found to enhance gray matter

Lithium has also been found to produce an increase in gray-matter portion of the brain consisting mainly of neuronal bodies, which shrinks with age more so than the white matter.7 Alzheimer’s disease (AD) actually causes the loss of neurons resulting in gray-matter shrinkage because the number of neurons that are still alive diminishes. So lithium may be especially important for AD. In another study, long-term lithium treatment was associated with increased gray-matter volumes in the same areas where suicide was associated with decreased volumes.8

How does lithium work?

Aside from all of the referenced findings about lithium made in “Lithium promotes longevity, mood, and love,” to which this sidebar is attached, lithium has many other properties. These include its usefulness in the treatment of acute brain injuries such as from ischemia and, aside from Alzheimer’s disease, other chronic neurodegenerative diseases such as Parkinson’s disease, Huntington’s disease, and amyotrophic lateral sclerosis. Also, one of the most important neuroprotective properties of lithium is its anti-apoptotic action. Ethanol (drinking alcohol) is a neuro­teratogen (a substance that causes malformations in a fetal brain). Fetal alcohol spectrum disorders (FASD) are caused by excessive maternal ethanol exposure during pregnancy and these disorders are the leading cause of mental retardation. Exposure to high amounts of alcohol causes neuroapoptosis (brain-cell suicide) in the developing brain. Furthermore, ethanol-induced loss of neurons in the central nervous system underlies many of the behavioral deficits observed in FASD. Excessive alcohol consumption is also associated with Wernicke-Korsakoff syndrome and neurodegeneration in the adult brain.

Recent in vivo and in vitro studies indicate that lithium is able to inhibit ethanol-induced neuroapoptosis,1 because it is an inhibitor of glycogen synthase kinase 3 (GSK3), which has recently been identified as a mediator of ethanol neurotoxicity (See Figure 1).

Accordingly, lithium’s neuroprotection may result from its inhibition of GSK3. As well, lithium also affects many other signaling proteins and pathways that regulate neuronal survival and differentiation. In fact, there is a multitude of recent evidence of lithium-mediated protection against ethanol neurotoxicity and potential underlying mechanisms.

Lithium found to increase neurogenesis, and memory

In the hippocampus, lithium was found to create new neurons (neurogenesis).9 The hippocampus is the center of memory and the organization of all your memories, and it’s one of the few areas of the brain where it’s possible for new neurons to grow. So this finding is very important. Another study has recently found that low-dose lithium may protect the microstructure of the hippocampus in ultra high-risk for psychosis patients showing that low-dose lithium has neuroprotective benefits.10 In another study, low-dose lithium was found to help mice with traumatic brain injury, enhancing spatial learning and memory performance as demonstrated in the Morris water maze test.11

Can lithium contribute to the feelings of new love?

A recent study has found that people with bipolar, depressive, and other psychiatric disorders are far less likely to maintain positive romantic attachments, as demonstrated by subjects with these disorders testing high on anxiety and avoidance scale.12 From the above references (Schrauzer, 1990; Berger, 2012; Zhe, 2010), we know that low-dose lithium can improve mood, and thus reduce anxiety.3,10-11

Also, another study (see “I’m in the mood for love” in the November 2012 issue) identified a clear relationship with new love and nerve growth factor (NGF) levels,13 and lithium increases NGF levels. In a recent review,14 “Lithium acts through multiple pathways to inhibit glycogen synthase kinase-3beta (GSK3 beta). This enzyme phosphorylates and inhibits nuclear factors that turn on cell growth and protection programs, including the nuclear factor of activated T cells (NFAT) and [the transription factor β-catenin in the Wnt pathway]. In animals, lithium upregulates neurotrophins, including brain-derived neurotrophic factor (BDNF), [NGF], neurotrophin-3 (NT3), as well as receptors to these growth factors in brain [bold added].” In reference 13, “Notably, there was also a significant positive correlation between levels of NGF and the intensity of romantic love as assessed with the passionate love scale.”

Also, according to that review, “Lithium also stimulates proliferation of stem cells, including bone marrow and neural stem cells in the subventricular zone, striatum, and forebrain. The stimulation of endogenous neural stem cells may explain why lithium increases brain cell density and volume in patients with bipolar disorders [bold added].”

Lithium increases happiness, friendliness, and energy

In a placebo-controlled study with former drug users (mostly heroin and methamphetamines),15 24 subjects (16 males and 8 females, average age 29.4 ± 6.5 years) were randomly divided into two groups, one receiving 400 μg of lithium per day in yeast, the other a placebo, for four weeks. All subjects completed weekly self-administered mood test questionnaires. In the lithium group, the total positive mood test scores increased steadily during the four weeks of supplementation; and specifically in the subcategories reflecting happiness, friendliness, and energy. In the placebo group, the combined mood scores showed no consistent changes; the happiness scores actually declined. Lithium is a sure bet to ensure your future, your mood, and perhaps even the love you enjoy!
