Abstract

Cognitive impairment is inherent to the ageing process. Several studies suggest that patients with late-life schizophrenia have more marked cognitive impairment.

Objective:

The aim of this study was to compare the cognitive performance of elderly institutionalized patients with schizophrenia and institutionalized elderly control patients without neurological or psychiatric diseases, matched for age, educational level and institutionalization time.

Methods:

The Cambridge Examination for Mental Disorders of the Elderly (CAMCOG) was used to test 10 institutionalized elderly patients with schizophrenia. Results were compared with those of 10 institutionalized control patients with history of Hansen's disease.

Results:

Patients with schizophrenia showed a worse performance in terms of total CAMCOG score and on its subtests of orientation, language, abstraction, and memory (p≤0.05). Patients with schizophrenia also disclosed a non-significant trend toward lower scores on the MMSE and on calculus.

Conclusion:

Findings demonstrated that schizophrenia was associated to worse cognitive impairment in long-term institutionalized elderly patients compared with institutionalized patients without neurological or psychiatric diseases.

Key words: elderly; cognition; institutionalization; schizophrenia.

Resumo

Prejuízo cognitivo é inerente ao processo de senescência. Estudos tem sugerido que pacientes idosos com esquizofrenia apresentam esse prejuízo de maneira mais acentuada.

Objetivo:

O objetivo deste estudo foi comparar o desempenho cognitivo de pacientes idosos com esquizofrenia, institucionalizados, com indivíduos idosos, institucionalizados, sem doenças neurológicas ou psiquiátricas, pareados pela idade, escolaridade e tempo de institucionalização.

Métodos:

"Cambridge Examination for Mental Disorders of the Elderly" (CAMCOG) foi aplicado em 10 pacientes, institucionalizados, com esquizofrenia, cujo desempenho cognitivo foi comparado ao de 10 indivíduos, institucionalizados, com história de doença de Hansen.

Resultados:

Pacientes com esquizofrenia apresentaram um pior desempenho na pontuação total do CAMCOG e em seus subitens orientação, linguagem, abstração e memória (p≤0.05). Pacientes com esquizofrenia também apresentaram uma tendência, não significativa, para menor pontuação no MEEM e cálculo.

Conclusão:

Nossos achados demonstram que a esquizofrenia está associada a piora do comprometimento cognitivo em pacientes idosos com institucionalização de longa permanência comparados a pacientes institucionalizados sem doenças neurológicas ou psiquiátricas.
