Neuroprotective agents are substances that help protect nerve cells from damage or degeneration. They can be used to treat various neurological disorders, such as Alzheimer's disease, Parkinson's disease, and multiple sclerosis. These agents work by reducing inflammation, preventing oxidative stress, and promoting cell survival. Common neuroprotective agents include certain vitamins, antioxidants, and medications like memantine and dopamine agonists. Research is ongoing to discover new compounds that can enhance brain health and function. By safeguarding neurons, these agents aim to slow the progression of neurodegenerative diseases and improve the quality of life for affected individuals.
