Epinephrine is just one chemical involved in your body's response to anxiety. Other chemicals may also play a role. For example, a serotonin imbalance¹ may contribute to anxiety, as can high cortisol levels. However, epinephrine is the primary chemical because it is directly involved in your anxiety symptoms.
Toxins are also called diabesogens and obesogens because they contribute to diabetes and obesity, which raise the risk of anxiety, depression, and Alzheimer's disease.
Mercury Poisoning and Anxiety and Depression. The psychological health of an individual can be jeopardized from mercury exposure. Mercury is bioaccumulative and slow to be released from the body. Exposure to mercury for any given amount of time can cause headaches, anxiety, memory issues, mood swings, and more.
According to the U.S. Environmental Protection Agency and the Agency for Toxic Substances and Disease Registry, the three substances that have the greatest impact on human health are mercury, lead and arsenic, and exposure to these toxic metals are known to cause anxiety and/or depression.
There is usually headache, confusion, and vomiting followed by a decline in consciousness, possibly leading to coma. Focal signs and seizures can occur but are uncommon. Cerebral edema can progress to cause herniation and brain death.
Chemicals believed to cause anxiety include serotonin, dopamine, norepinephrine, and gamma-aminobutyric acid (GABA).
People with clinical depression often have increased levels of monoamine oxidase A (MAO-A), an enzyme that breaks down key neurotransmitters, resulting in very low levels of serotonin, dopamine and norepinephrine.
Exposure to stressful and adverse experiences over a long period of time can become toxic. This repeated exposure to stress without the benefit of buffering protection of a supportive, adult relationship has been termed toxic stress.
A subset of brain cells that release a fight-or-flight chemical called norepinephrine unexpectedly reduces anxiety and stress in mice, according to new findings by NIEHS researchers. The study, published Sept.
Benzodiazepines (also known as tranquilizers) are the most widely prescribed type of medication for anxiety. Drugs such as Xanax (alprazolam), Klonopin (clonazepam), Valium (diazepam), and Ativan (lorazepam) work quickly, typically bringing relief within 30 minutes to an hour.
In Primary Sjögren's syndrome (pSS), neuropsychiatric manifestations have been reported in up to 80% of adults; and often, it precedes the diagnosis in up to 50–80% cases. Anxiety, depression, and cognitive dysfunction are commonly seen in pSS.

For the most part, an individual can detox from substances within a week (though cravings may persist for months afterward). Some of withdrawal most serious symptoms seem nonfatal, such as vomiting and diarrhea.
Our bodies remove dead blood cells and other waste products through a network of vessels called the lymphatic system. The brain, however, uses a different method. Cerebrospinal fluid cleanses brain tissue.
Anti-amyloid antibodies work by alerting the immune system to the presence of amyloid plaques and directing a cleanup crew called microglia to clear out such debris.
The scientists also reported that the glymphatic system can help remove a toxic protein called beta-amyloid from brain tissue. Beta-amyloid is renowned for accumulating in the brains of patients with Alzheimer's disease. Other research has shown that brain levels of beta-amyloid decrease during sleep.
