Demência devida à hidrocefalia de pressão normal resulta do acúmulo excessivo de líquido cefalorraquidiano no cérebro, como resultado de causas idiopáticas não obstrutivas, mas também pode ser secundário a hemorragia, infecção ou inflamação. A progressão é gradativa, mas a intervenção (p. ex., derivação) pode resultar em melhora dos sintomas, especialmente se realizada precocemente no curso da condição. Tipicamente, comprometimentos cognitivos incluem velocidade de processamento reduzida e déficits na funcionalidade executiva e na atenção. Esses sintomas também são tipicamente acompanhados de anormalidades da marcha e incontinência urinária. Exame de imagem cerebral para mostrar o volume ventricular e caracterizar o deslocamento cerebral frequentemente é necessário para confirmar o diagnóstico. | |||
