Medicinal Plants and Their Phytoconstituents in Neurodegenerative Disorders

The human brain is made up of neurons and neuroglia, the latter of which are essential for maintaining neurons and responding to injury. Brain activity impairment can result from malfunctioning neuroglia. Chronic neuroglial activation affects neurodegeneration, which has a major impact on brain aging and neuropathological diseases. There are intriguing neuroprotective chemicals in traditional medicine that may offer an effective option than synthetic drugs. Researchers can improve natural treatments for neurological disorders by isolating active phytochemicals while discovering more about their processes, doses, and safety profiles. A variety of food sources including marine algae have neuroprotective properties. Bioactive substances with anti-inflammatory and antioxidant properties are found in marine algae. Nuts, fruits, vegetables, and other foods include phytochemicals that can prevent neurodegeneration. Resveratrol, curcumin, sulforaphane, flavonoids, and organosulfur compounds are important substances that shield neurons by a variety of mechanisms, such as anti-inflammatory and antioxidant ones. In addition to supporting general brain health, a varied diet high in these neuroprotective chemicals may lower the risk of neurological disorders.
