Can Brain Fog After A Viral Infection Be Linked To Neurological Inflammation? Neurologist Answers [Video]

What Is Brain Fog?

Dr. Anand says, “Brain fog is a term used to denote lack of concentration, thinking or memory in a normal person after infection or stress or use of chemotherapeutic agents after taking alcohol or recreational drugs.
