Clouding of consciousness
open-in-new
<p>Clouding of consciousness, also called brain fog or mental fog, occurs when a person is <a href="/facts/Consciousness/IAxmgt6c">conscious</a> but slightly less <a href="/facts/Wakefulness/eukTx8fQ">wakeful</a> or <a href="/facts/Awareness/PazhgWFC">aware</a> than normal. They are less aware of time and their surroundings, and find it difficult to <a href="/facts/Attentional_control/gPbUhqSq">pay attention</a>. People describe this <a href="/facts/Subjectivity/XVvftgCU">subjective</a> sensation as their mind being "<a href="/facts/Fog/mrIdyIc7">foggy</a>". </p>
