Executive attention and working memory in narcoleptic outpatients / Atenção executiva e memória de trabalho em pacientes com narcolepsia

OBJECTIVE: This pioneering study aimed to evaluate executive attention and working memory in Brazilian narcoleptic outpatients. METHODS: Narcoleptic group: 19 treated narcoleptic outpatients (13 F; 6 M) (mean age=37.58; SD = 8.93); control group: 19 subjects (15 F; 4 M) (mean age=34.42; SD=12.31). INSTRUMENTS: Epworth Sleepiness Scale - Brazilian Portuguese Version (ESS-BR), Victoria Stroop Test (VST), Trail Making Test (TMT) and Letter-Number Sequencing (LNS) of WAIS-III. RESULTS: Significant difference at Excessive Daytime Sleepiness (EDS) (p<0.001) and at working memory (p=0.009) with worse results for narcoleptic patients. Patients were slower at VST-1 (p=0.002), VST-2 (p=0.045) and at TMT-A (p=0.016), TMT-B (p=0.006) and B-A (p=0.024). CONCLUSION: Narcoleptic patients showed higher degrees of EDS, an impaired executive attention at a temporal level and lower performance in working memory when compared to normal controls.

OBJETIVO: Este estudo pioneiro teve como objetivo avaliar a atenção executiva e a memória de trabalho em pacientes brasileiros com narcolepsia. MÉTODOS: Grupo-estudo: 19 narcolépticos tratados (13 M; 6 H), com média de idade de 37,58 anos, DP=8,93; grupo-controle: 19 sujeitos (15 M; 4 H), com média de idade de 34,42 anos, DP=12,31. UTILIZARAM-SE: a Escala de Sonolência de Epworth-BR, Victoria Stroop Test (VST), Trail Making Test (TMT) e Sequência de Números e Letras (SNL) da WAIS-III. RESULTADOS: Houve diferença significativa nos graus de Sonolência Diurna Excessiva (SDE) (p<0,001) e na memória de trabalho (p=0,009), com piores resultados para o grupo-estudo. Do mesmo modo, verificaram-se tempos aumentados no grupo-estudo para execução do VST-1 (p=0,002), VST-2 (p=0,045) e TMT-A (p=0,016), e TMT-B (p=0,006) e B-A (p=0,024). CONCLUSÃO: Os pacientes com narcolepsia apresentaram graus mais elevados de SDE, prejuízo na atenção executiva em nível temporal e desempenho inferior da memória de trabalho em relação aos sujeitos-controles.

Professor Antonio Branco Lefèvre: the forefather of child neurology in Brazil.

OBJECTIVE: To report on the life and works of Prof. Antonio Branco Lefèvre and the relevance that led him to be considered the Forefather of Child Neurology in Brazil. METHOD: The method utilized was the historical documents research; bibliographical. RESULTS: Antonio Branco Lefèvre (1916-1981) was born in São Paulo city; graduated in 1941 from the São Paulo Medical School. The date--1950--can be considered when Child Neurology took shape for a fully specialty, when Lefèvre presented his two internationally acclaimed thesis. Lefèvre was recognized as he founder of Child Neurology in Brazil since the early years of his brilliant academic activities. In 1967 achieved the title of professor in the Child Neurology Clinic. His numerous trainees and Residents--from -1950 to 1981--held today key positions in Brazilian Child Neurology. CONCLUSION: The extension and importance of the Child Neurology School of which he is the legitimate founder is recognized.

Sustained attention assessment of narcoleptic patients: two case reports.

Narcolepsy is a sleep disorder characterized by uncontrollable REM sleep attacks which alter the patients wake state and can lead to difficulties in attention aspects, such as maintaining attention when performing activities or tasks. This study aimed to evaluate sustained attention performance of two narcoleptic patients on the d2 Test, Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI) and Hamilton Rating Scale for Depression (HAM-D). Results showed that the maintenance of attention was associated with a slowing of the target symbols processing function in visual scanning with accuracy in task performance. A high degree of excessive sleepiness was observed, along with mild and moderate degrees of depressive signs and symptoms. One subject also presented with a nocturnal sleep disorder which could represent an important factor affecting attentional and affective capacity.

A narcolepsia é um distúrbio do sono caracterizado por ataques diurnos incontroláveis de sono REM, que alteram o estado de vigília dos pacientes, podendo levar a dificuldades na expressão de aspectos da atenção, como a sua manutenção durante a execução de atividades ou tarefas. Este estudo buscou avaliar a atenção sustentada de dois pacientes com narcolepsia através do Teste d2, da Escala de Sonolência Epworth, do Índice de Qualidade de Sono de Pittsburgh (IQSP) e da Escala de Hamilton para Avaliação da Depressão (HAM-D). Os resultados revelaram que a manutenção da atenção mostrou-se associada ao alentecimento no processamento dos símbolos-alvo na sondagem visual, com precisão na execução da tarefa. Houve presença de sonolência excessiva em nível elevado e sinais e sintomas depressivos em grau leve e moderado. Um dos sujeitos apresentou também prejuízo do sono noturno, podendo ser este mais um fator importante na expressão da capacidade atencional e afetiva.
