Angiopatía amiloide cerebral - Overview

Nombres alternativos

Amiloidosis cerebral; CAA

Definición:

Es una afección neurológica en la cual las proteínas llamadas amiloides se acumulan en las paredes de las arterias cerebrales. Esta afección incrementa el riesgo de accidente cerebrovascular hemorrágico y demencia.

Causas, incidencia y factores de riesgo:

La causa de la angiopatía amiloide cerebral se desconoce. Las personas con esta afección tienen depósitos de proteína amiloide en las paredes de las arterias del cerebro. La proteína generalmente no se deposita en ninguna otra parte del cuerpo.

El mayor factor de riesgo es la edad avanzada. De hecho, la proporción de esta afección es mucho más alta en personas mayores de 60 años.
