Brain fog, though not a medical term, describes a condition that many find impactful in their daily lives. It refers to feelings of mental confusion or lack of mental clarity, often described as cloudiness or a cognitive fog. While it may not sound severe, it can significantly affect concentration, memory, and overall cognitive function, leading to challenges in both personal and professional life.Unlike specific nerve roots in conditions like radiculopathy, brain fog is more about a general impairment of cognitive functions. It can be seen as a traffic jam in the brain's communication networks, affecting how signals are processed and interpreted.
