Memory mood congruency phenomenon in bipolar I disorder and major depression disorder patients

The objective of the present study was to evaluate memory performance in tasks with and without affective content (to confirm the mood congruency phenomenon) in acutely admitted patients with bipolar I disorder (BD) and major depression disorder (MDD) and in healthy participants. Seventy-eight participants (24 BD, 29 MDD, and 25 healthy controls) were evaluated. Three word lists were used as the memory task with affective content (positive, negative and indifferent). Psychiatric symptoms were also evaluated with rating scales (Young Mania Rating Scale for mania and Hamilton Depression Rating Scale for depression). Patients were selected during the first week of hospitalization. BD patients showed higher scores in the word span with positive tone than MDD patients and healthy controls (P = 0.002). No other difference was observed for tests with affective tone. MDD patients presented significantly lower scores in the Mini-Mental State Exam, logical memory test, visual recognition span, and digit span, while BD patients presented lower scores in the visual recognition test and digit span. Mood congruency effect was found for word span with positive tone among BD patients but no similar effect was observed among MDD patients for negative items. MDD patients presented more memory impairment than BD patients, but BD patients also showed memory impairmen

Alterações cognitivas em trabalhadores de uma empresa de processamento de dados Cognitive problems in workers of a data processing company

Realizou-se estudo de 191 trabalhadores de uma empresa federal de processamento de dados em Porto Alegre, RS, Brasil, em 1989, objetivando estudar déficits cognitivos. São analisadas as relações entre queixas de alteração de memória e os respectivos desempenhos em testes de avaliação cognitiva segundo três grupos de trabalhadores, o primeiro com atividades automatizadas e repetitivas (digitadores) e dois outros com funções diversificadas. Utilizou-se um teste de rastreamento psiquiátrico para controlar esta possível variável de confusão. Existe uma alta prevalência de queixas de perda de memória (65,4%), apesar de não haver evidências significativas de problemas cognitivos. Observou-se uma associação estatisticamente significativa entre a presença ou não de queixas de memória e o desempenho no teste psiquiátrico. Sugere-se que futuros estudos enfatizem o aspecto de saúde mental e sofrimento psíquico para compreensão destas queixas, tendo em vista as características do processo de trabalho na informática.<br>A study of 191 data processing workers undertaken in Porto Alegre, Brazil, in 1989, is presented. The relationship between complaints of loss of memory and their respective scores on cognitive testing in three groups of workers, one with automatized repetitive activities and two others with diversified activities, is analysed. The scores and complaints are compared with the results of a screening test for psychiatric disorders in order to verify the influence of this confounding factor. No significant evidence of cognitive problems was found despite the high prevalence of complaints of memory loss in this population (65,4%). There is a significant statistical association between these complaints and the scores of the psychiatric testing. It is suggested that futures studies should emphasize psychiatric analysis with a view to clarifying the complaints of Data Processing workers
