Reduced Cognitive Performance

Q: What is reduced cognitive performance?

Reduced cognitive performance describes a decline from an individual's typical level of mental functioning — slower processing speed, reduced working memory capacity, impaired verbal fluency, or diminished executive function — that makes cognitively demanding tasks noticeably harder. It differs from global cognitive impairment in being more focal or situational. Common contributors include acute and chronic sleep deprivation (the most reversible cause), nutritional deficiencies, thyroid dysfunction, anaemia, chronic stress, depression, ADHD, medication side effects, and post-viral fatigue syndromes.
