Brain Fog

London, one evening after the work. After long long long period of work with no break.

Brain fag is an example of a culture-bound syndrome. Seen predominantly in male students, it generally manifests as vague somatic symptoms, depression, and difficulty concentrating. The term "brain fag" was used in the US as far back as 1852, describing an overworked brain,[2] in 1877 to describe mental exhaustion in professionals similar to neurasthenia.
