Neuroprotection refers to the strategies and mechanisms that protect neuronal structure and function. In the context of toxicology, neuroprotection aims to shield the nervous system from toxic insults, reduce neuronal death, and preserve cognitive and motor functions. The need for neuroprotection arises from exposure to neurotoxic agents such as heavy metals, pesticides, and industrial chemicals, which can lead to neurodegenerative diseases like Parkinson's disease and Alzheimer's disease.
