ABSTRACT
OBJETIVO: Comparar o desempenho cognitivo de idosos com psicose, depressão e demência em um ambulatório de saúde mental. MÉTODOS: Aplicou-se o miniexame do estado mental (MEEM) e o Cambridge Cognitive Examination (CAMCOG) em 86 pacientes com mais de 60 anos de idade encaminhados para avaliação por queixas de memória. Os pacientes foram diagnosticados seguindo os critérios da DSM IV. Os dados sociodemográficos foram expressos em média (desvio padrão). Comparou-se os escores do MEEM e CAMCOG dos pacientes com psicose, demência e transtorno do humor utilizando-se o teste t de Student e Anova. RESULTADOS: Da população total - idade: 70,87 (dp=6,61); m=32; f=54; analfabetos=41, escolarizados=45 - 17 (19,7 por cento) tinham demência, 11 (12,8 por cento) psicose e 58 (67,4 por cento) transtorno do humor. O MEEM do grupo total foi de 21,07 (dp=6,61) e CAMCOG de 61,50 (dp=19,78). MEEM/CAMCOG por diagnósticos: Demência: 16,76 (dp=6,25) / 48 (dp=20,49); Psicose: 20,9 (dp=5,87) / 60,09 (dp=13,54); Transtornos do humor: 22,36 (dp=5,49) / 66,03 (dp=18,88). A pontuação do MEEM e CAMCOG de demenciados foi significativamente menor que a dos pacientes com transtorno do humor (Anova p < 0,01). A pontuação de pacientes com psicose não se diferenciou da dos pacientes com demência e da dos pacientes com transtornos do humor (p > 0,05). CONCLUSÃO: A avaliação cognitiva breve permite uma diferenciação sindrômica entre depressão e demência, mas não entre depressão e psicose, em pacientes idosos de um ambulatório psiquiátrico que apresentam queixas de memória. Estes dados podem servir para a organização de um protocolo simples e de baixo custo para o atendimento da população em serviços de saúde pública.
OBJECTIVE: To evaluate the cognitive performance of the elderly with psychosis, depression and dementia in a mental health outpatient unit. METHODS: The Mini-Mental State Examination (MMSE) and the Cambridge Cognitive Examination (CAMCOG) were applied to 86 patients above 60 years of age referred for evaluation due to memory complaints. Patients were diagnosed according to DSM IV criteria. Socio-demographic data were expressed as means (standard deviation); MMSE and CAMCOG score of patients with psychosis, dementia and mood disorders were compared using Student's T test and ANOVA. RESULTS: Of the total sample (age: 70.87 (sd=6.61); male=32; female=54; illiterate=41, educated=45; 17 (19.7 percent) had dementia, 11 (12.8 percent) psychosis and 58 (67.4 percent) mood disorders. The MMSE of the total sample was 21.07 (sd=6.61) and the CAMCOG = 61.50 (sd=19.78). MMSE/CAMCOG of each diagnosis: Dementia: 16.76 (sd=6.25)/48(sd=20.49); Psychosis: 20.9 (sd=5.87)/60.09 (sd=13.54); mood disorders: 22.36 (sd=5.49)/66.03 (sd=18.88). The MMSE and CAMCOG scores of patients with dementia were significantly lower than those of patients with mood disorders (ANOVA p < 0.01). The score of patients with psychosis was not different from scores of those with dementia and mood disorders (p >0.05). CONCLUSION: A brief cognitive evaluation permits a differentiation between dementia and depression but not between psychosis and depression in elderly patients of a psychiatric outpatient unit, who had complained of memory impairment. These data may be useful to develop an easy and low cost protocol to attend the population of public health services.
