ABSTRACT

OBJECTIVES:

To verify the accuracy of prospective memory (ProM) tests in Alzheimer's disease (AD).

METHODS:

Twenty mild AD patients (CDR 1), and 20 controls underwent Digit Span (DS), Trail Making (TM) A and B, visual perception, Rey Auditory-Verbal Learning tests, and Cornell Scale for Depression. AD diagnosis was based on DSM-IV and NINCDS-ADRDA criteria. ProM was assessed with the appointment and belonging subtests of Rivermead Behavioral Memory Test (RBMT); and with two new tests (the clock and animal tests).

RESULTS:

AD patients had a worse performance than controls on the majority of tests, except DS forward and TM-A. There was no correlation between RBMT and the new ProM tests. As for accuracy, the only significant difference concerned the higher sensitivity of our animal test versus the RBMT belonging test.

CONCLUSIONS:

The clock and the animal tests showed similar specificity, but higher sensitivity than the RBMT subtests.
RESUMO

OBJETIVOS:

Verificar a acurácia dos testes de memória prospectiva (MP) na doença de Alzheimer (DA).

MÉTODOS:

Foram avaliados 20 pacientes com DA leve (CDR 1; diagnóstico baseado no DSM-IV e NINCDS-ADRDA) e 20 controles passaram pelos testes de dígitos, das trilhas A e B, de percepção visual, do aprendizado verbal de Rey e da Escala Cornell para Depressão. MP foi avaliada com os subtestes de compromisso e pertence do Teste de Memória Comportamental da Rivermead e dois novos testes (do relógio e dos animais).

RESULTADOS:

Os pacientes com doença de Alzheimer tiveram um desempenho inferior aos controles na maioria dos testes, exceto nos dígitos diretos e na trilha A. Não houve correlação entre os subtestes de Memória Comportamental da Rivermead e os novos testes de memória prospectiva. A única diferença quanto à acurácia foi que o teste dos animais teve maior sensibilidade que o do pertence da Rivermead.

CONCLUSÕES:

Os testes do relógio e dos animais mostraram similar especificidade, porém maior sensibilidade do que os subtestes da Rivermead.
