Inflammation in the brain can lead to damage to neurons and other essential cells, disrupting normal brain function. Chronic inflammation is often linked to various conditions such as autoimmune disorders, infections, or prolonged exposure to toxins. This inflammatory response can impair communication between brain cells, reduce neuroplasticity, and ultimately contribute to cognitive deficits. Addressing underlying inflammation through dietary changes, medication, and lifestyle adjustments can help mitigate its impact on cognitive health.
