Mild Cognitive Impairment
Marcadores cognitivos, biológicos, anatómicos y conductuales del deterioro cognitivo leve y la enfermedad de Alzheimer. Una revisión sistemática. Cognitive, biological, anatomical and behavioral markers of mild cognitive impairment and Alzheimer’s disease. A systematic review
Alzheimer’s disease (AD) is a progressive neurodegenerative disease that affects 50% of people over 85 years of age and is one of the most common in adulthood and the most common cause of dementia in developed countries. The objective was to determine which have been the most studied cognitive, biological, anatomical and behavioral markers of mild cognitive impairment (MCI) and AD in the last 10 years. Observational studies were searched in the Scopus, Pubmed and Sciencedirect databases. 187 articles were identified, of which 23 with full text were finally selected. The studies corresponded to cognitive (15 studies), biological (8 studies), anatomical (3 studies) and behavioral (2 studies) markers. The identified markers will help guide the design of early detection programs and future interventions that reduce neuropathological effects and significant alterations in quality of life.

Batería Neuropsicológica Set de Datos Uniformes (UDS) Para la Evaluación de Enfermedad de Alzheimer y Deterioro Cognitivo Leve: Una Revisión Sistemática. Neuropsychological Battery Uniform Data Set (Uds) For The Evaluation Of Alzheimer’s Disease And Mild Cognitive Impairment: A Systematic Review.
The neuropsychological battery UDS (of the English Uniform Data Set), is used worldwide to homogenize the investigations of Alzheimer’s disease. Objective: Quantitatively synthesize the results of the subtests of the UDS for the cognitive profile of controls, patients with mild cognitive impairment and dementia of the Alzheimer type. Method: An advanced and manual systematic search was performed in databases (PubMed / MedLine, Web of Science, Scopus, Lilacs, Science Direct, Cochrane Library, PsycINFO) evaluating the diagnostic performance of the UDS. Results: The systematic review showed a narrative synthesis where 8 articles were included that included 9260 subjects, with an age range between 60 and 90 years. The quantitative synthesis used 13 articles with a total sample of 2,884 participants, with an average age of 74 years and an average of 15 years of education. Conclusion: We described a synthesis of the medial scores, which generate cut-off points for Alzheimer’s type dementia (DTA), mild cognitive impairment (MCI) and cognitively normal controls, evidencing an adequate diagnostic precession.
