Escala de detección de olvidos. Una herramienta de rastrillaje para el deterioro cognitivo leve.

The prevalence of memory disorders in adulthood requires sensitive, specific and quick administration screenings instruments for the detection of cognitive impairment. Objective: To establish the validation of EDO, a brief questionnaire to be completed by the patient's informant, which serves to detect subjects with mild cognitive impairment. It is an instrument that can be administered in a simple manner and has the advantage of not needing the presence of the patient. The questionnaire has 10 quick response questions to be used in the clinic. Methods: 44 patients with mild cognitive impairment and 40 normal controls matched by age and educational level were evaluated with EDO and with an extensive Neuropsychological Battery. Results: Groups differed significantly in the EDO, MMSE (p <.001), CDR (p <.001) and RAVLT (p <.001). The EDO showed a significant correlation with the CDR (r = .524, p < .001), with RAVLT (r = -.551, p < .001) and with the FAQ (r = .705; p < .001). The area under the ROC curve was 0.835 and a cut-off score of 4 had a sensitivity of 0.75 and specificity of 0.78 to detect mild cognitive impairment. Conclusions: EDO is a fast and easy administration instrument with adequate psychometric properties to be used in MCI detection. [ABSTRACT FROM AUTHOR]
