Clouding of consciousness

Clouding of consciousness is a symptom of decreased alertness, confusion, and disorientation. It is often caused by a medical condition, such as a stroke, head trauma, or drug overdose. It can also be caused by a lack of sleep, dehydration, or intoxication. The symptom manifests itself in a decrease in mental clarity, difficulty concentrating, confusion, and difficulty responding to questions. It can also include changes in behavior, such as aggression, restlessness, agitation, and difficulty staying focused. As the symptom develops, the person may become increasingly unresponsive and difficult to rouse.
