Inflammation and Neurological Disorders

Inflammation is a crucial biological response that plays a significant role in the body's defense against harmful stimuli, such as pathogens, damaged cells, or irritants. While acute inflammation is a normal and essential part of the immune response, chronic inflammation can lead to various health issues, including neurological disorders. In this course, we will explore the relationship between inflammation and neurological disorders and how nutritional strategies can help mitigate these conditions.
