Cognitive fatigue
Cognitive fatigue (also called exhaustion, tiredness, lethargy, languidness, languor, lassitude, and listlessness) is medically recognized as a state usually associated with a weakening or depletion of one's mental resources.

The intensity and duration of this effect typically depends on the substance consumed and its dosage. It can also be further exacerbated by various factors such as a lack of sleep
[3]
or food
[4]
. These feelings of exhaustion involve a wide variety of symptoms which generally include some or all of the following effects:
- Analysis suppression
- Motivation suppression
- Thought deceleration
- term memory suppression
- Thought disorganization
- Language suppression
- Creativity suppression
Cognitive fatigue is most commonly induced under the influence of moderate dosages of antipsychotic compounds, [5] [6] such as quetiapine, haloperidol, and risperidone. However, it can also occur during the withdrawal symptoms of many depressants [7] , and during the offset of many stimulants [8] .
