Neurotoxicology studies the effects of toxic substances on the nervous system, focusing on how environmental, pharmaceutical, or industrial chemicals contribute to neurological disorders. Exposure to neurotoxic agents, such as heavy metals, pesticides, and certain drugs, can lead to long-term cognitive and motor impairments, including neurodegeneration, memory loss, and behavioral changes. Research in neurotoxicology is aimed at understanding the molecular mechanisms underlying these toxic effects, particularly how toxins interact with neurons and disrupt synaptic function. Advances in biomarker identification and neuroimaging techniques are improving the ability to detect early signs of neurotoxicity, enabling more effective prevention and treatment. By identifying high-risk individuals and minimizing exposure to harmful substances, neurotoxicology is playing a crucial role in safeguarding neurological health.
