The Brief Cognitive Assessment Tool (BCAT) was designed and copywrited by Dr. William Mansbach to identify patients with and without dementia, and to be sensitive to different levels of cognitive impairment. The BCAT was designed as a multi-domain cognitive screening tool that assesses orientation, verbal recall, visual recognition, visual recall, attention, abstraction, language, executive functions, and visuo-spatial processing. The BCAT, as well as the three cognitive BCAT "factors" (contextual memory, executive functions, and attention), have been shown to predict both cognitive diagnosis and functional status or Instrumental Activities of Daily Living (IADL). The BCAT has been validated and published in the Journal of Clinical and Experimental Neuropsychology, 2012, Vol 34(2), 183-194. An abbreviated form of the Brief Cognitive Assessment Tool (BCAT-SF) has been published in the journal Aging and Mental Health, 2012, Vol 16(8), 1065-1071. The BCAT can be administered in 10–15 minutes. ==Background== Over the past thirty years, cognitive functioning in older adults has become an important focus among clinicians and policy analysts. The increasing longevity of older adults, especially those in the "old-old" category, has been well documented. Epidemiological studies show that as people live longer, incidence and prevalence rates of dementia also increase. It is estimated that more than 5 million Americans over the age of 65 have Alzheimer's Disease (AD). This number is projected to exceed 13 million by 2050. While no clear preventive or curative interventions for Alzheimer’s disease are available, early detection may improve quality of life for patients and their families. Furthermore, effective screening may aid in the development of intervention strategies that delay the insidiousness of the disease as well as nursing facility placement. Early detection may enhance the efficacy of pharmacologic and non-pharmacologic treatments. A number of screening measures have been developed since the Mini-Mental State Examination (MMSE) was published in 1975. Examples include the Short Test of Mental Status (STMS), the Montreal Cognitive Assessment (MoCA), and the St. Louis University Mental Status Examination (SLUMS). While each of these instruments identifies individuals with probable dementia, they lack specific integration of three critical neuro-cognitive clusters (contextual memory, executive functions, and attentional capacity) as predictors of cognitive functioning and performance of everyday activities of independent living. The BCAT was designed to overcome this and other measurement issues. Whereas the BCAT can be administered in a short period of time (10–15 minutes), a Short Version (BCAT-SF) has also been developed and normed. It can be administered in less than five minutes and is ideal for primary care settings and frontline providers who have little time to spend screening patients. The BCAT-SF can be also be administered, scored, and interpreted on-line in "real time" (as can the full BCAT). The psychometric properties of the BCAT-SF are robust. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Brief Cognitive Assessment Tool」の詳細全文を読む スポンサード リンク
