There is a mineral that may help prevent and slow the progression of Alzheimer’s and other forms of dementia: lithium.
In large doses, lithium has been used for years as a medication to treat bipolar disorder and depression.
In much smaller microdoses of around 300-1,000 mcg, it has shown benefits in Alzheimer’s patients.
As a physician, I advise anyone over the age of 60, or anyone with mild cognitive impairment, to start taking microdoses of oral lithium.
It’s safe, passes easily through the blood-brain barrier, and has been shown to increase production of neurons in the brain.
Lithium holds promise in protecting against neurodegeneration and in promoting longevity.
Where Lithium Comes From
Lithium is a mineral present in nearly all rocks and natural water sources.
Today, people get small amounts from natural spring water, grains, vegetables, eggs, and milk.
The World Health Organization considers lithium a nutritionally essential trace element, alongside zinc, iodine, and others.
Lower Rates of Dementia
Doctors have long used high doses of lithium to treat bipolar disorder and depression.
Scientists noticed that bipolar patients receiving lithium had lower rates of cognitive decline than patients on other medications.1 That got them interested in whether lithium could be used to treat neuro-degenerative disorders.
To test this observation, researchers compared the rates of Alzheimer’s disease in 66 elderly bipolar patients using chronic lithium therapy with 48 similar patients who were not prescribed this mineral.
In patients receiving lithium, just 5% had Alzheimer’s, compared with 33% in the non-lithium group.2
Two studies in Denmark confirmed similar results. Investigators surveyed the records of over 21,000 patients who had received lithium treatment and found that it was associated with a reduced rate of Alzheimer’s and other forms of dementia.3,4
And in 2018, researchers studying lithium levels in different regions of Texas discovered that rates of death from Alzheimer’s diseasewere higher in areas with low levels of lithium in the water.5
This finding indicates that high lithium drug doses may not be needed to confer neuroprotection.
Based on findings from a 2020 study of Alzheimer’s disease in rats, scientists from McGill University have suggested that microdoses of lithium could slow the progression of Alzheimer’s in its initial stages and even improve cognition.6
How Lithium Protects the Brain
Experimental and clinical studies offer evidence of the many ways that lithium exerts neuroprotective effects.
Microdoses of lithium may help maintain the length of telomeres, protective caps on the ends of chromosomes.7,8 Telomere length has been linked to increased longevity and to warding off diseases, including Alzheimer’s.
Research shows that lithium promotes the synthesis and release of two vital proteins, brain-derived neurotrophic factor (BDNF) and neurotrophin-3.9
These are both neurotrophic factors, which means they stimulate the growth, development, and repair of brain cells.9,10 This may explain why patients on lithium have a significantly higher volume of gray matter, the layer of the brain containing nerve cell bodies.11,12
One study directly demonstrated that damaged nerve cells exposed to lithium respond with increases in the number and length of dendrites, the parts of neurons that receive signals from other neurons.13
Lithium reduces levels of an enzyme called glycogen synthase kinase-3 (GSK-3). This enzyme is involved in the production of neurofibrillary tangles, which lead to the damaging plaques found in the brains of patients with Alzheimer’s.14-16
Lithium also reduces oxidative stress and inflammation, providing additional neuroprotection.1
A placebo-controlled trial was conducted on people with a form of mild cognitive impairment that made it difficult to learn or recall new information. The study found that low-dose lithium was associated with lower concentrations of abnormal tau proteins in cerebrospinal fluid.17
Lithium improved performance on multiple cognitive scales, suggesting that it may slow the progression of cognitive and functional deficits.17
In another human study, just 300 mcg of lithium daily significantly decreased cognitive decline in Alzheimer’s patients compared to a placebo.18
WHAT YOU NEED TO KNOW
Lithium Protects the Brain
- Lithium is a mineral found in the earth’s crust and in many natural bodies of water.
- Large doses of lithium have long been used to treat bipolar and other mood disorders.
- Some studies have found that bipolar patients on lithium therapy have lower rates of cognitive decline, Alzheimer’s disease, and other forms of dementia than those not on lithium.
- Lithium works in a variety of ways to help the brain produce new neurons and to prevent the buildup of neuro-fibrillary tangles and plaques seen in the brains of Alzheimer’s patients.
- Human studies demonstrate that microdoses of lithium improve cognitive performance in patients with mild cognitive impairment, and decrease cognitive decline in patients with Alzheimer’s disease.
In a third study, the cognitive function of patients with early-stage dementia who took lithium remained more stable than in those individuals who took a placebo.19
I believe that every patient with signs and symptoms of dementia should be on microdoses of oral lithium. Further experimentation in large-scale clinical trials is still required to assess the true ability of lithium to treat or prevent dementia and cognitive decline.
The mineral lithium has benefits in the brain.
It has long been used to treat mood disorders, and there is evidence that its neuroprotective properties can help prevent and slow the progression of Alzheimer’s and other forms of dementia.
Studies show that lithium stimulates the growth of neurons, inhibits the development of neurofibrillary tangles seen in the brains of Alzheimer’s patients, maintains and increases the length of protective telomeres, and much more.
Every person above the age of 60 or 65, or anyone with signs of dementia, could benefit from microdoses of oral lithium to promote brain health and protect cognitive function.

LITHIUM’S LITTLE-KNOWN HISTORY
Most people think of lithium as a treatment for mental illnesses. But it has a long history as a general health tonic, used to treat ailments as wide-ranging as asthma, gout, and migraines.
Lithium springs, where water contains naturally high amounts of the mineral, were popular destinations in the 19th and 20th centuries, visited by people from near and far, including famous people of the day.
Lithium was also used to fortify foods and beverages. In 1929, a soft drink inventor named Charles Leiper Grigg created a beverage called Bib-Label Lithiated Lemon-Lime Soda, now known as 7-Up. The soda contained lithium until 1950 and was originally marketed for its potential to cure hangovers and lift the mood.
Its modern use in the treatment of mental disorders began in 1948 in Australia. The U.S. Food and Drug Administration first approved its use in 1970. Read MORE hERE……….
