Clouded Consciousness (also Known As Clouding Of Consciousness)
Clouded consciousness (also known as clouding of consciousness) is a state of extreme inattention and lack of alertness. Not having a clear head, this is often called a 'mental fog' or 'brain fog.' Consciousness is at a lower functioning level than normal but the diminished alertness is not as severe as someone in a state of deliruim. Clouded consciousness can be a symptom of some forms of encephalopathy, anaphylaxis, Lyme disease, Wernicke's encephalopathy, and tapeworms.
