Mold is bad news for the brain.

1/19/2020

In a recent journal published in Brain, Behavior and Immunity* we can truly see how mold is bad news for the brain. In this study they dripped Stachybotrys fungi into the nose of rats (can’t imagine having this job!) and found within a short period of time hippocampal immune activation, decreased memory and striking anxiety and as well reduced levels of dopamine .

Study findings included:
1. People are typically exposed to complex mixtures of molds, bacteria, and dust that activate stronger, synergistic immune responses than predicted by adding the effects of the individual stimuli.
2. Mold exposure in homes is underestimated.
3. Most mold exposure is not from spores, but to nanoparticles that are often hundreds, up to as much as a million times, more numerous and penetrate much deeper into the lungs than whole spores and inhaled mold and mycotoxins that essentially “hijack” the olfactory highway into the brain. Of note, it appears the brain is highly vulnerable to mold invasion due to its high fat content and the lipophilic nature of mold. Many mycotoxins can easily cross the blood brain barrier and disrupt not only microglial cells, but also astrocyte that provide the scaffolding and oligodendrocytes, which are important for myelin production.
4. Since exposure to mold often persists for months or even years, it might be expected to cause prolonged innate immune activation of the type already demonstrated to be neurotoxic in a variety of diseases and even if mold exposure is ceased, neuro-immune mechanisms persists for a long time.
5. Mold exposure, both toxic and nontoxic, must be considered another factor like pesticide exposure or smoking that can add to an individual’s burden of inflammation with possible serious consequences for health and behavior.

Bottom line: Mold is a real concern and can negatively impact the wellbeing of our brains! As more studies provide links between neurological conditions and mold exposure, we can only hope that the resulting disorders exhibited by our patients is taken more seriously as a very real medical issue.

My friend talked about his plans to move into a new home for his music composer goals. I never knew that prolonged mold exposure could affect your daily life by going straight to your body. Maybe we should start by having his future home inspected for these first before finalizing his move.

I had no idea that mold exposure comes from nanoparticles. My basement might have mold. I'll have to have an inspection scheduled.

Thanks so much for explaining that after exposure mold can often persist in the body for months or years. My brother has been noticing that his basement is beginning to smell musty and he's worried about mold forming. We'll have to look into hiring some mold removal specialists to help him test and remove any dangerous mold or damaged material.

I didn't know that mold was similar to pesticide exposure. My wife and I need to get a mold specialist to help with an inspection. I'll have to consider getting a detector.

I never took into account the fact that we might be experiencing prolonged immune activation due to the molds persisting for months or years. I hope that we are not too late when we discovered that we might have them in our basement, because we have lived here for three years now. We should immediately call a mold remediation service tomorrow so that we do not prolong it anymore before we experience any health issues in our family.

Having read the article "Mold Is Bad News for the Brain" on Dr. Suzanne Gazda's website, I wanted to provide some additional insights and information related to the potential effects of mold on the brain.

The article highlights the potential health risks associated with mold exposure, particularly in relation to neurological symptoms and cognitive function. While it is true that certain types of mold can release mycotoxins, which may have harmful effects on human health, the specific impact on the brain is a topic that requires further scientific research and investigation.

Here are some key points to consider:

Allergic Reactions: Mold spores can trigger allergic reactions in sensitive individuals, which may manifest as respiratory symptoms, skin irritation, or eye irritation. While these allergic responses can indirectly affect cognitive function due to discomfort and difficulty focusing, the direct impact on brain health is not yet fully understood.

Mycotoxins and Neurotoxicity: Some species of mold can produce mycotoxins, which are toxic substances that can cause various health problems. While there is evidence to suggest that exposure to high levels of certain mycotoxins can have neurotoxic effects, the research in this area is still limited and inconclusive. More studies are needed to establish a clear and direct link between mold-associated mycotoxins and brain health.

Individual Sensitivities: It's important to acknowledge that people may react differently to mold exposure. Some individuals may be more susceptible to the potential health effects of mold due to underlying health conditions, allergies, or genetic factors. It is always advisable to consult with a healthcare professional if you have concerns about mold exposure and its impact on your health.

Indoor Air Quality: Regardless of the direct effects on the brain, mold can contribute to poor indoor air quality, which can have adverse effects on overall well-being. It is important to address mold issues promptly to create a healthy living environment.

While the potential health risks associated with mold exposure are a topic of ongoing research, it is essential to maintain a clean and dry living environment to minimize the likelihood of mold growth. If you suspect mold in your home or workplace, it is advisable to consult with professionals who can assess the situation and provide appropriate guidance.

It is worth noting that this response is based on the information available up until my knowledge cutoff in September 2021. As new research and scientific findings emerge, our understanding of the relationship between mold and brain health may evolve.

If you have specific concerns about mold exposure or its potential effects, I recommend consulting with a qualified healthcare professional who can provide personalized advice based on your individual circumstances.
