Non-Alzheimer's disease-related memory impairment and dementia
Abstract
Although Alzheimer's disease (AD) is a common cause of memory impairment and dementia in the elderly disturbed memory function is a widespread subjective and/or objective symptom in a variety of medical conditions. The early detection and correct distinction of AD from non-AD memory impairment is critically important to detect possibly treatable and reversible underlying causes. In the context of clinical research, it is crucial to correctly distinguish between AD or non-AD memory impairment in order to build homogenous study populations for the assessment of new therapeutic possibilities. The distinction of AD from non-AD memory impairment may be difficult, especially in mildly affected patients, due to an overlap of clinical symptoms and biomarker alterations between AD and certain non-AD conditions. This review aims to describe recent aspects of the differential diagnosis of AD and non-AD related memory impairment and how these may be considered in the presence of memory deficits.
Aunque la Enfermedad de Alzheimer (EA) constituye una causa común de demencía y deterioro de memoria en la vejez, el trastorno de memoria es un síntoma generalizado objetivo ylo subjetivo en una variedad de situaciones médicas. La detección precoz y la correcta distinción entre la EA y el deterioro de memoria no-EA es muy importante para determinar causas subyacentes posiblemente tratables y reversibles. En el contexto de la investigation clínica es clave distinguir correctamente entre EA y deterioro de memoria no-EA para conformar poblaciones homogéneas de estudio para la evaluación de nuevas alternativas terapéuticas. La distinción entre EA y deterioro de memoria no-EA puede resultar difícíl, especialmente en pacientes con compromise leve, debido a una sobreposición de sintomas clínicos y alteraciones de biomarcadores entre la EA y ciertas condiciones no-EA. Esta revisóon tiene como objetivo describir aspectos recientes del diagnóstico diferencial de la EA y del deterioro de memoria no relacionado con la EA, y cómo estos pueden considerarse cuando hay presencia de déficit de memoria.
La maladie d'Alzheimer (MA) est une cause fréquente de troubles de la mémoire et de démence chez les sujets âgés mais une fonction mnésique perturbée est un symptôme subjectif et/ou objectif très répandu dans de nombreuses pathologies. La détection précoce et une distinction correcte entre troubles mnésiques lies ou non à la MA sont primordiales pour diagnostiquer des causes sous-jacentes qui pourraient être réversibles et traitables. En recherche clinique, faire cette distinction est essentiel pour constituer des populations d'étude homogènes afin d'évaluer de nouveaux traitements. La superposition des symptômes cliniques et des modifications des biomarqueurs entre la MA et d'autres pathologies non-MA peut rendre difficile la différentiation selon I'étiologie, surtout chez les patients légèrement atteints. Dans cet article nous décrivons les caractéristiques récentes du diagnostic différentiel entre troubles mnésiques liés ou non à la MA et leur prise en compte en présence d'un déficit de la mémoire.
