ABSTRACT

Objective Besides significant cognitive decline, patients in later stages of Alzheimer's disease (AD) also present global functional impairment, usually reported by their caregivers. This study searched for preserved activities of daily living by investigating correlations among specific instruments for severe dementia with a performance-based functional scale. Method A sample of 95 moderate to severe AD patients and their caregivers underwent a neuropsychological battery consisting of screening tools, the Functional Assessment Staging Test (FAST), the Severe Mini-Mental State Examination (MMSEsev) and a performance-based ecological scale, the Performance Test of Activities of Daily Living (PADL). Results Consistent findings emerged from the comparisons among tests. PADL showed significant statistical correlation with MMSEsev (ρ<0.001), according to FAST subdivisions. Conclusion Upon suspicion of unreliable caregiver reports, ecological scales may be useful for disease staging. Variable degrees of functionality and cognition may be present even in later stages of AD, requiring proper assessment. .


Objetivo Além do significativo declínio cognitivo, pacientes em estágios avançados da doença de Alzheimer (DA) também apresentam prejuízo funcional global. Este estudo investigou atividades de vida diária correlacionando teste específico para a demência grave, com escala funcional baseada no desempenho. Método 95 pacientes com DA foram submetidos a uma bateria neuropsicológica composta por instrumentos de rastreio, a escala Functional Assessment Staging Test (FAST), o Mini-exame do Estado Mental grave (MEEMg) e escala ecológica baseada no desempenho: a Performance Test of Activities of Daily Living (PADL). Resultados Achados consistentes emergiram da comparação entre os instrumentos. De acordo com as subdivisões da escala FAST, a PADL apresentou significativa correlação estatística com o MEEMg (ρ<0.001). Conclusão Na suspeita de relato pouco confiável por parte do cuidador, escalas ecológicas podem ser úteis no estadiamento da doença. Igualmente à cognição, variados graus de funcionalidade estão presentes mesmo em fases avançadas da DA, exigindo avaliação adequada. .
