- The Facts: A 2020 study found that the aluminum content in brain tissue of people with Alzheimer’s disease, familial Alzheimer’s disease, autism spectrum disorder and multiple sclerosis is significantly higher compared to tissues used in the study as controls.
- Reflect On: Could aluminum be playing a role in these, as well as other diseases? How does it get into our brain?
There is no shortage of studies demonstrating that aluminum is present in human brain tissue. This is a problem given the fact that aluminum is neurotoxic and wreaks nothing but havoc on biology. This is firmly established in scientific literature. There is no debate on whether or not aluminum exists within human brain tissue, the science is settled. The debate is now focused on how much aluminum is too much. How much aluminum does it take to impact the health of a human being in a negative way?
A study published in the journal Nature compared the aluminum content in human brain tissue of people with Alzheimer’s disease, familial Alzheimer’s disease, autism spectrum disorder and multiple sclerosis with healthy controls.
According to the authors, “detailed statistical analyses showed that aluminum was significantly increased in each of these disease groups compared to control tissues.” They go on to mention that,
We have confirmed previous conclusions that the aluminum content of brain tissue in Alzheimer’s disease, autism spectrum disorder and multiple sclerosis is significantly elevated. Further research is required to understand the role played by high levels of aluminum in the aetiology of human neurodegenerative and neurodevelopmental disease.
The researchers used tissue from twenty control brains of healthy individuals to compare against the brain tissue of people who have had a diagnosis of the neurodegenerative conditions mentioned. The fact that all disease groups had significantly higher brain aluminum content than the control group is quite concerning. That being said, it’s not proof that aluminum actually plays a direct role in each of these diseases. The important takeaway from the study and what we know about aluminum toxicology is that there is absolutely no debate, at all, as to the neurotoxicity of aluminum in humans. It’s just not a good thing to have in your body.
