Neuroprotectants: The Next Frontier in Neurology.

Neuroprotectants are drugs or substances that help protect the brain and nerves from damage caused by injuries or diseases like stroke, Alzheimer's disease, and Parkinson's disease. This review looks at different types of neuroprotective agents, including those that reduce inflammation, prevent cell death, or improve blood flow to the brain. While many of these substances show good results in lab studies, only a few have been successful in human trials. This is often due to problems like delayed treatment, difficulty reaching the brain, and differences between patients. The review also discusses future clinical trials and how new technologies and targeted treatments may improve outcomes. Understanding how these agents work and how to test them better could lead to more effective treatments for brain disorders.
