Neuroprotective drugs are medications designed to protect nerve cells from damage or degeneration. They are often used in conditions like Alzheimer's disease, Parkinson's disease, and multiple sclerosis, where nerve cell health is compromised. These drugs aim to preserve neuronal function and promote cell survival, potentially slowing disease progression. These medications work through various mechanisms, such as reducing inflammation, preventing oxidative stress, and enhancing blood flow to the brain. Research continues to explore new neuroprotective agents, with the hope of improving outcomes for patients suffering from neurodegenerative disorders and other neurological conditions.
