Metal Toxicity Depression: Mercury, Arsenic, Cadmium

December 2, 2015 – Posted by: Albert Mensah, MD, BCIP

“Metal toxicity depression is the least common biotype for depression, notwithstanding copper. In our research and in our history of empirical evidence through Carl Pfeiffer, MD, PhD, William Walsh and the Pfeiffer Treatment Center, and here at Mensah Medical, we have corroborated that fewer than 5% of cases of depression are affected primarily by metal toxicity. Therefore, we rarely see cases of true metal toxicity depression. Please note, this does not include conditions of brain fog, impaired thinking, or erratic behaviour.”



Can Heavy Metal Toxicity Lead To Mental Health Problems Like Depression Or Anxiety?

Cabot Health – By Margaret Jasinska, Naturopath March 28, 2016

“Recent addiction problems among former Australian swimmers have prompted a female former professional swimmer (who wants to remain anonymous) to reveal her long-term struggle with depression. She claims her depression was largely caused by copper toxicity, through overexposure to chlorine.”


Blood lead levels and major depressive disorder, panic disorder, and generalized anxiety disorder in U.S. young adults

“Lead is a ubiquitous neurotoxicant, and adverse cognitive and behavioural effects are well documented in children and occupationally exposed adults but not in adults with low environmental exposure.


To investigate the association of current blood lead levels with three common psychiatric disorders, major depression, panic, and generalized anxiety, among young adults.”



Everything you think you know about addiction is wrong

“What really causes addiction — to everything from cocaine to smart-phones? And how can we overcome it? Johann Hari has seen our current methods fail firsthand, as he has watched loved ones struggle to manage their addictions. He started to wonder why we treat addicts the way we do — and if there might be a better way. As he shares in this deeply personal talk, his questions took him around the world, and unearthed some surprising and hopeful ways of thinking about an age-old problem.”

Everyday Plastic Ingredient BPA Damages Brain Cells And Affects Mood And Memory

“Scientists in the US and Canada studying the effects of bisphenol-A (BPA), an ingredient of polycarbonate plastic used to make common everyday items for storing food and medicines, found it caused loss of connections between brain cells in primates and may lead to disruption in memory and learning as well as depression. Based on their findings the scientists suggest the US Environmental Protection Agency lower the current safe limit for human daily exposure to BPA.”



Prenatal BPA Exposure Linked to Anxiety and Depression in Boys


Aug. 16 2016

“Boys exposed prenatally to a common chemical used in plastics may be more likely to develop symptoms of anxiety and depression at age 10-12. The new study by researchers at the Columbia Center for Children’s Environmental Health (CCCEH) within the Mailman School of Public Health examined early life exposure to the chemical Bisphenol A (BPA). Results are published in the journal Environmental Research.”



Is Plastic Making You Anxious? – The scary new reason to bypass BPA


“In baseball, it’s three strikes and you’re out. That doesn’t seem to be the case for bisphenol A, or BPA, a chemical that acts like estrogen and tampers with the body’s normal hormone functioning. In study after study, researchers have been implicating the common chemical in the growing prevalence of ailments like obesity, cancer, type 2 diabetes, infertility, and behavioural problems.”

Every day we are exposed to toxins from our environment. We may ingest lead and copper from drinking water, phosphate from processed food and soda, various synthetic chemicals from plastic food containers, and pesticides from fruits and vegetables. Both natural heavy metals and man-made chemicals disrupt hormones and brain development. The brain, especially the developing brain, is very vulnerable to contaminants because of its large size (relative to total body weight) and its high concentration of fats which serve as a reservoir for toxicants to build up. This article will explain the role that heavy metals and environmental toxins play in mental health.
