Neurotoxicity or a neurotoxic effect: an adverse change in the chemistry, structure, or function of the nervous system following exposure to a chemical or physical agent
Voluntarily and involuntarily, we are exposed to a range of chemicals that affect the nervous system. We spend billions of dollars every year voluntarily purchasing chemicals such as caffeine, alcohol, and nicotine to influence our nervous system. Most stores and many industries are dependent on our desire to influence our nervous system. Many of us are familiar with the undesirable effects of too much caffeine or alcohol, which is a form of neurotoxicity. Fortunately, we quickly recover from the neurotoxic effects of caffeine or alcohol and learn to manage our consumption of these chemicals to minimize the undesirable effects and maximize the desirable effects. In this sense, many of us are experienced neurotoxicologists.
