Your nervous system helps control a number of physiological processes, allowing for movement, cognitive thought, personality development and memory, as well as regulating several other processes essential for life. A number of nutrients, including essential minerals, contribute to the health of your nervous system. However, exposure to excess amounts of these minerals can have a negative effect on your nerves, potentially causing neuropathy, or nerve damage.
Potassium
Nerve damage can have an effect on potassium, an essential mineral. Your body relies on potassium to help promote nervous system functioning, as the mineral contributes to the electrochemical impulses that occur within your nerve cells. Too little potassium in your system may hinder efficient nerve signaling, leading to muscle weakness or temporary paralysis. Individuals with autonomic neuropathy face an increased risk of potassium deficiency, according to MedlinePlus, since the diarrhea and vomiting that can occur as a result of the condition reduce levels of potassium in the body. If you suffer from autonomic neuropathy, talk to your doctor about a potential need for potassium supplementation.
Iron
Another mineral linked to nerve damage is iron. Though iron in your body supports red blood cell functioning, consuming too much iron can lead to a number of side effects, including damage to your nervous system. The Linus Pauling Institute at Oregon State University explains that individuals who consume large doses of iron may experience nervous system failure in the days following iron consumption. Individuals who survive this initial stage may develop irreparable damage to their central nervous system in the weeks after their iron overdose, as well as permanent damage to other organs and tissues.
Manganese
Exposure to manganese can also lead to nerve damage in some cases. Manganese toxicity often occurs as a result of exposure to manganese dust, a workplace hazard found in welding factories. Upon inhalation, your body absorbs and transports the manganese dust to your brain, leading to neurological toxicity. Over time, severe manganese toxicity can lead to a lack of control over muscle movement, leading to symptoms that resemble those of Parkinson's disease.
Selenium
Another mineral linked to nerve damage is selenium -- a mineral that can both positively and negatively affect the health of your nervous system. Selenium normally helps activate a range of enzymes, called selenoproteins, that help support your cells' functioning. Individuals suffering from diabetic neuropathy might benefit from selenium supplements, reports the NYU Langone Medical Center. On the other hand, selenium toxicity caused by a supplement can actually contribute to nerve damage, according to Texas Tech University. If you suffer from diabetic neuropathy, talk to your doctor about the potential benefit of selenium supplements, and only take selenium at a dosage recommended by your physician.
