The Clinical Dementia Rating or CDR is a numeric scale used to quantify the severity of symptoms of dementia (i.e. its 'stage'). Using a structured-interview protocol developed by Charles Hughes,〔Br J Psychiatry. 1982 Jun;140:566-72. A new clinical scale for the staging of dementia. Hughes CP, Berg L, Danziger WL, Coben LA, Martin RL.〕 Leonard Berg, John C. Morris and other colleagues at Washington University School of Medicine, a qualified health professional assesses a patient's cognitive and functional performance in six areas: memory, orientation, judgment & problem solving, community affairs, home & hobbies, and personal care. Scores in each of these are combined to obtain a composite score ranging from 0 through 3.〔()〕 Clinical Dementia Rating Assignment Qualitative equivalences are as follows:NACC Clinical Dementia Rating CDR is credited with being able to discern very mild impairments, but its weaknesses include the amount of time it takes to administer, its ultimate reliance on subjective assessment, and relative inability to capture changes over time.〔(Utility of the Clinical Dementia Rating in Asian Populations - Lim et al. 5 (1): 61 - Clinical Medicine & Research )〕 ==Validity== While the assessment is ultimately subjective in nature, recent studies have suggested a very high interrater reliability.〔()〕 Thus the CDR appears to be a reliable and valid tool for assessing and staging dementia. 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「Clinical Dementia Rating」の詳細全文を読む スポンサード リンク
