Clouding of consciousness
Clouding of Consciousness
Clouding of consciousness (pronunciation: /ˈklaʊdɪŋ ɒv ˌkɒnʃəsˈnɛs/) is a medical term used to describe a state of confusion, lack of clear thinking, or attention deficit that can occur suddenly or over time due to various medical conditions.
Etymology
The term "clouding of consciousness" is derived from the English words "clouding", which means becoming less clear or transparent, and "consciousness", which refers to the state of being aware and able to think and perceive. The term metaphorically describes the state of mind where thoughts and perceptions become unclear or less transparent, similar to how a cloud obscures the clear sky.
Definition
Clouding of consciousness is characterized by a reduced awareness of the environment, difficulty in maintaining attention to external stimuli, and impaired short-term memory. It is a common symptom in many neurological and psychiatric disorders, and can also be caused by systemic diseases, medications, or substance abuse.
