Demência é caracterizada pela presença de comprometimento acentuado em dois ou mais domínios cognitivos em relação ao esperado para a idade e nível geral pré-mórbido de funcionalidade cognitiva do indivíduo, que representa um declínio do nível prévio de funcionalidade do indivíduo. O comprometimento da memória está presente na maioria das demências, mas o comprometimento cognitivo não se restringe à memória (i.e., há comprometimento em outras áreas, como funções executivas, atenção, linguagem, cognição e julgamento social, velocidade psicomotora, habilidades visuoperceptivas ou visuoespaciais). Mudanças neurocomportamentais também podem estar presentes e, em algumas formas de demência, podem ser o sintoma de apresentação. O comprometimento cognitivo não é atribuível a envelhecimento normal e é grave o suficiente para interferir significativamente com a independência no desempenho das atividades de vida cotidiana pelo indivíduo. Presume-se que o comprometimento cognitivo seja atribuível a uma doença adquirida subjacente do sistema nervoso, um traumatismo, uma infecção ou outro processo patológico que afete o cérebro, ou ao uso de substâncias ou medicamentos específicos, deficiência nutricional ou exposição a toxinas, ou a etiologia pode ser indeterminada. O comprometimento não se deve a intoxicação ou abstinência atual de uma substância. | |||

Dementia is characterized by the presence of marked impairment in two or more cognitive domains relative to that expected given the individual’s age and general premorbid level of cognitive functioning, which represents a decline from the individual’s previous level of functioning. Memory impairment is present in most forms of dementia, but cognitive impairment is not restricted to memory (i.e., there is impairment in other areas such as executive functions, attention, language, social cognition and judgment, psychomotor speed, visuoperceptual or visuospatial abilities). Neurobehavioural changes may also be present and, in some forms of dementia, may be the presenting symptom. Cognitive impairment is not attributable to normal aging and is severe enough to significantly interfere with independence in an individual’s performance of activities of daily living. The cognitive impairment is presumed to be attributable to an underlying acquired disease of the nervous system, a trauma, an infection or other disease process affecting the brain, or to use of specific substances or medications, nutritional deficiency or exposure to toxins, or the etiology may be undetermined. The impairment is not due to current substance intoxication or withdrawal. | |||
