Resumen
La anosognosia es un trastorno común, multifactorial y de naturaleza compleja tras daño cerebral, donde los pacientes no son conscientes de su trastorno.
En este artículo, revisamos la anosognosia en la enfermedad de Alzheimer (EA).
La anosognosia en la EA es considerada como una faceta multidi-mensional. Se han propuesto varias teorías que pretenden explicar la no toma de consciencia de los déficits neurológicos o cognitivos, como las teorías neuroanatómicas, neurológicas o psicopatológicas. La anosognosia en la EA es frecuente. Numerosos estudios encuentran una correlación significativa entre la gravedad de la demencia y lesiones en el hemisferio cerebral derecho o una disfunción de tipo frontal, pero se dan resultados contradictorios.

Abstract
Anosognosia is a common, multifactorial, complex disorder after brain damage, in which patients remain unaware of their disability. To review data on anosognosia in Alzheimer's disease (AD). Anosognosia in la AD is considered to be multidimensional. Several theoretical frameworks, such as neuroanatomic, neurological or psychopathological theories, aim to explain the lack of unawareness of neurological or cognitive impairment.
Anosognosia is frequent in AD. Many studies have found a significant correlation between the severity of dementia and right hemisphere damages or frontal dysfunction, but the results are contradictory.
Key words:
Anosognosia
Dementia
Awareness
Alzheimer
Frontal syndrome
