Editing Attention deficit

'''Attention deficit/decreased attention span''' is one of the symptoms of the [[cognitive dysfunction]] associated with [[ME/CFS]].

==Presentation==

==Prevalence==
*In a 2001 Belgian study, 93.0% of patients meeting the [[Fukuda criteria]] and 95.9% of patients meeting the [[Holmes criteria]], in a cohort of 2073 [[chronic fatigue syndrome|CFS]] patients, reported attention deficit.<ref name="DeBecker2001">{{Cite journal | last = De Becker | first = Pascale | author-link = Pascale De Becker | last2 = McGregor | first2 = Neil | author-link2 = Neil McGregor | last3 = De Meirleir | first3 = Kenny | author-link3 = Kenny De Meirleir | date = December 2001 | title = A definition‐based analysis of symptoms in a large cohort of patients with chronic fatigue syndrome | url =https://onlinelibrary.wiley.com/doi/full/10.1046/j.1365-2796.2001.00890.x?sid=nlm%3Apubmed | journal = Journal of Internal Medicine | volume = 250|issue=3 | pages = 234–240|doi=10.1046/j.1365-2796.2001.00890.x|quote=|via=}}</ref>

==Symptom recognition==
*In the [[Canadian Consensus Criteria]], impairment of concentration and short-term memory consolidation is an optional criteria for diagnosis, under the section ''Neurological/Cognitive Manifestations''.<ref>[http://sacfs.asn.au/download/consensus_overview_me_cfs.pdf ''A Clinical Case Definition and Guidelines for Medical Practitioners: An Overview of the Canadian Consensus Document''] Pg 8. 2005.</ref>
*In the [[Fukuda criteria]], the symptom of substantial impairment in concentration can be used to help form a diagnosis.<ref>[http://www.cfids-me.org/cdcdefine.html The CDC (Fukuda 1994) Definition for Chronic Fatigue Syndrome]</ref>
*In the [[Holmes criteria]], '''inability to concentrate''' is an optional criteria for diagnosis, under the section ''Minor Symptom Criteria - Neuropsychologic Complaints''.<ref>[http://www.cfids-me.org/holmes1988.html The 1988 Holmes Definition for CFS]</ref>
*In the [[ME/CFS: A Primer For Clinical Practitioners|IACFS/ME Primer for Clinical Practitioners]] (2014), decreased attention span is listed in the cognitive symptoms.<ref name="IACFSME2014primer">{{citation | last1 = ((International Association for Chronic Fatigue Syndrome / Myalgic Encephalomyelitis)) | author-link = International Association for Chronic Fatigue Syndrome/Myalgic Encephalomyelitis | last2 = Friedberg | first2 = Fred | author-link2 = Fred Friedberg | last3 = Bateman | first3 = Lucinda | author-link3 = Lucinda Bateman | last4 = Bested | first4 = Alison C | author-link4 = Alison Bested | last5 = Davenport | first5 = Todd | author-link5 = Todd Davenport | last6 = Friedman | first6 = Kenneth J | author-link6 = Kenneth Friedman | last7 = Gurwitt | first7 = Alan R | author-link8 = Alan Gurwitt | last8 = Jason | first8 = Leonard A | author-link8 = Leonard Jason | last9 = Lapp | first9 = Charles W | author-link9 = Charles Lapp | last10= Stevens | first10 = Staci R | author-link10 = Staci Stevens | last11= Underhill | first11 = Rosemary A | author-link11 = Rosemary Underhill | last12= Vallings | first12 = Rosamund | author-link12 = Rosamund Vallings | date = 2014 | url=https://www.massmecfs.org/images/pdf/Primer_2014.pdf | title =Chronic Fatigue Syndrome Myalgic Encephalomyelitis Primer for Clinical Practitioners }}</ref>

==Notable studies==
*2006, Cognitive dysfunction relates to subjective report of mental fatigue in patients with chronic fatigue syndrome<blockquote>"CFS patients with significant complaints of mental fatigue (score of mental fatigue 2 standard deviations above the mean of nonfatigued subjects) exhibited significant impairment in the spatial working memory and sustained attention (rapid visual information processing) tasks when compared to CFS patients with low complaints of mental fatigue and nonfatigued subjects. In CFS patients with significant mental fatigue, sustained attention performance was impaired only in the final stages of the test, indicating greater cognitive fatigability in these patients."<ref name="Capuron, 2006"/></blockquote>
