Neurotoxic effects refer to damage caused to the nervous system by harmful substances, known as neurotoxins. These toxins can disrupt normal brain function, leading to symptoms such as headaches, memory loss, and coordination problems. Common sources of neurotoxins include certain chemicals, heavy metals like lead and mercury, and some drugs. Exposure to neurotoxins can occur through various routes, including ingestion, inhalation, or skin contact. The severity of the effects often depends on the type of toxin, the level of exposure, and individual susceptibility. Long-term exposure can result in chronic neurological disorders, affecting overall health and quality of life.
