Can Heavy Metals Cause Neurodegeneration? A Functional IV Therapy Toronto Report

Did you know that your nerve cells are in charge of the communications that happen in your brain and nervous system? These ‘messengers’ are called neurons. With age, they can slowly weaken in both form and function. Integrative functional medicine and IV therapy treatments from Toronto may be beneficial for supporting neuronal health, with the potential to prevent or delay neurodegeneration. 

Neurodegeneration is the gradual loss of structure and/or function of the neurons. It involves chronic injury to the neurons that can eventually lead to cell death. Unlike other cells, neurons are limited in their ability to regenerate. So once neuronal damage accumulates beyond a certain threshold, it can potentially impair cognitive function, movements, emotional regulation, and memory. You may already be familiar with some neurodegenerative conditions, such as Alzheimer’s disease, Parkinson’s, multiple sclerosis (MS) and amyotrophic lateral sclerosis (ALS). 

While genes can contribute to forming neurodegeneration, studies are postulating that heavy metal exposures can influence the onset and progression of neurodegeneration. We explain further in this new post from the Toronto Functional Medicine Centre. 

How are we exposed to heavy metals?

Industrialization has significantly boosted our interactions with heavy metals. These exposures can happen from:  

• Food and water: Mercury from predatory fish, arsenic in contaminated groundwater or rice, lead from old plumbing
• Air pollution: Industrial emissions, vehicle exhaust, cigarette smoke
• Occupational exposure: Mining, welding, manufacturing, 
• Household products: Cosmetics, cookware, some older paints

Heavy metals bioaccumulate – this means that they can collect in tissues quicker than the body can remove them. Thus, low chronic exposures can potentially be problematic for long-term health outcomes, especially if they impact the brain.

The role of heavy metals in neurodegeneration

There’s a chance that heavy metal accumulations can hinder neurological health. Here’s how: 

• May cause oxidative stress: Mercury and lead can overpower antioxidant defences in the brain, causing excessive amounts of reactive oxygen species (ROS). The brain is vulnerable to toxicities due to its high fat content and oxygen demand, and oxidative stress can damage neurons, DNA, and proteins.
• Heavy metals appear to cause mitochondrial dysfunction: Excessive heavy metals can impair the production of ATP (adenosine triphosphate) in the mitochondria, your body’s source of cellular energy. “As the brain consumes a large amount of energy, mitochondrial dysfunction and the subsequent decrease in levels of ATP may significantly disrupt brain function, resulting in neuronal cell death and ensuing neurological disorders,” reports an article from Toxics. 
• Could potentially trigger neuroinflammation: Heavy metals can cause cell death and activate microglia, the brain’s immune cells. Chronic neuroinflammation can be triggered by these exposures, which happens to be the hallmark of several neurodegenerative conditions, including Alzheimer’s and Parkinson’s.
• May promote abnormal protein folding: Proteins must fold into unique shapes in order to work properly. But research has shown that aluminum, iron, and mercury can promote abnormal protein folding. Specific misfolded proteins can contribute to forming beta-amyloid plaques, such as those in Alzheimer’s disease. 
• Heavy metals can disrupt the blood-brain barrier: Your body’s blood-brain barrier (BBB) is meant to protect the nervous system from any toxicities lurking in the blood. Some metals, like cadmium, can compromise the integrity of the BBB. This can allow for additional toxins and inflammatory molecules to enter the brain and potentially instigate neurological damage.

Actionable tips for prevention and support

Target heavy metal exposures can possibly help prevent or slow down neurodegeneration. Functional medicine involves addressing the root cause, which might be beneficial for managing neurodegenerative symptoms, like balance issues, irritability, and memory loss. Key strategies may include: 

• Functional medicine testing: Comprehensive heavy metal testing can identify which and how much toxins are affecting your health. Functional health practitioners then use these lab results to coordinate and dose your treatment plan. 
• Supporting detoxification: Targeted supplements, nutritional regimes, and lifestyle modifications may be advised for enhancing liver function, bile flow, and gut health.
• Reducing environmental exposures: You might be advised to use water filtration systems at home, make dietary changes, practice occupational safety measures, and look into using natural household products. 
• Adopting anti-inflammatory foods: A holistic nutritionist can help you boost your intake of antioxidants, omega-3 fatty acids, and phytonutrient-rich foods – these ingredients are advantageous for fostering detoxification. 
• Chelation treatments: Depending on your lab results, chelation therapy may be advised. This involves ingesting a chelating agent that binds to heavy metals for excrement. 
• Getting a prescription for IV vitamin therapy: In some cases, IV drip therapies may be part of a comprehensive treatment plan, especially for stimulating cellular repair. This may be advised if you’re struggling with absorption issues. Intravenous therapy can deliver high doses of antioxidants, like vitamin C and glutathione, to reduce oxidative stress. IV magnesium, B vitamins, and amino acids can also be administered to support mitochondrial functioning. Furthermore, detoxification can be further supported with IV therapy using NAC (N-acetylcysteine) to help support detoxification.

The fact that heavy metals can fast-track neurological decline is alarming – but we can take steps to help prevent or delay neurodegeneration. The integrative functional medicine approach can be explored to assist with early detection and brain health preservation. If you have concerns about environmental exposures, you should know that we’re currently accepting new patients. Let’s introduce you to our personalized framework for enhancing your wellness.

Whether your goal is to reset your digestive system or boost mental clarity, the Toronto Functional Medicine Centre has got your back! Our wellness therapies – which include naturopathic medicine, acupuncture, cryotherapy, and more – adhere to the principles of integrative functional medicine, which means we adapt modalities for biological purposes. Our curated treatments are suitable for handling chronic conditions, especially for supporting cognitive function, bone and muscle function, changes to metabolic processes, and autoimmune diseases. 

We understand that navigating wellness can be a wavering experience – this is why our clinicians provide you with extended appointment times, helping you understand how to read lab reports, practice healthy habits at home, and know the rationales behind prescribed modalities. Targeted supplements can be picked up in our in-house dispensary, too, where we also coordinate botanical remedies into teas, topicals, oils, and more. 

IV drip therapies are administered in our IV Lounge and sessions are closely supervised by our health team. We can also prescribe intramuscular vitamin injections with vitamin D, glutathione, or B12 – ask us for more details anytime! Our IV therapy treatments are freshly blended with zinc sulfate, various B vitamins, amino acids, NAD+ (nicotinamide adenine dinucleotide), NAC, vitamin E, and more – and just like our other integrative functional medicine treatments, doses are personalized for key needs and goals. When intravenous therapy is interwoven with a healthy lifestyle and other formal health interventions (i.e. Western and/or naturopathic medicine), then they may be supportive for immune function, daily energy levels, and other general needs.
