Brain fog is the inability to think clearly or remember things that you would normally easily recall. Although there is no published definition of brain fog, people describe it as not being able to think clearly and access information that would normally be easy for them to recall. It’s a feeling of mental fog clouding a person’s ability to think and function making people feel detached, discouraged and sometimes even depressed. Brain fog is not yet acknowledged as a clinical diagnosis because it’s more of a subjective feeling rather than something easily tested for.
