Résumé

Traumatic brain injury (TBI) is a major public health problem inWestern countries. ATBI brings many negative consequences, including behavioral and cognitive changes, which affect social adjustment and the performance of functional activities. Cognitive evaluation after TBI is a complex issue in what pertains to definition of the most appropriate questionnaires for clinical use in a comprehensive analysis of the condition of the patient. In this paper, we described a critical review of the main cognitive assessment tests currently used in clinical and research settings in patients with TBI.

Résumé

ABSTRACT Objective To investigate the long-term efficacy of acoustically controlled auditory training in adults after tarumatic brain injury. Methods A total of six audioogically normal individuals aged between 20 and 37 years were studied. They suffered severe traumatic brain injury with diffuse axional lesion and underwent an acoustically controlled auditory training program approximately one year before. The results obtained in the behavioral and electrophysiological evaluation of auditory processing immediately after acoustically controlled auditory training were compared to reassessment findings, one year later. Results Quantitative analysis of auditory brainsteim response showed increased absolute latency of all waves and interpeak intervals, bilaterraly, when comparing both evaluations. Moreover, increased amplitude of all waves, and the wave V amplitude was statistically significant for the right ear, and wave III for the left ear. As to P3, decreased latency and increased amplitude were found for both ears in reassessment. The previous and current behavioral assessment showed similar results, except for the staggered spondaic words in the left ear and the amount of errors on the dichotic consonant-vowel test. Conclusion The acoustically controlled auditory training was effective in the long run, since better latency and amplitude results were observed in the electrophysiological evaluation, in addition to stability of behavioral measures after one-year training.


RESUMO Objetivo Investigar a eficácia de longo prazo do treinamento auditivo acusticamente controlado em indivíduos adultos após traumatismo craniencefálico. Métodos Foram estudados seis indivíduos audiologicamente normais com idades entre 20 e 37 anos, que sofreram traumatismo craniencefálico grave com lesão axional difusa, submetidos a um programa de treinamento auditivo acusticamente controlado aproximadamente um ano antes. Foram comparados os resultados obtidos nas avaliações comportamental e eletrofisiológica do processamento auditivo imediatamente após o treinamento auditivo acusticamente controlado e a reavaliação, um ano após. Resultados Quanto ao potencial de tronco encefálico, observou-se aumento da latência absoluta de todas as ondas e os intervalos interpicos, na comparação entre as avaliações, bilateralmente, bem como aumento da amplitude de todas as ondas, sendo a onda V estatisticamente significativa, para a orelha direita e a onda III para a orelha esquerda. Quanto ao P3, observaram-se diminuição da latência e aumento da amplitude do P3 na avaliação atual em ambas as orelhas. A avaliação comportamental atual evidenciou desempenho semelhante nas duas avaliações, exceto no teste dicótico de dissílabos alternados na orelha esquerda e a quantidade de erros no teste dicótico consoante-vogal. Conclusão O treinamento auditivo acusticamente controlado mostrou-se eficaz em longo prazo, uma vez que foram observados resultados melhores de latência e amplitude na avaliação eletrofisiológica, bem como estabilidade das medidas comportamentais após um ano de treinamento.

Résumé

Presentamos el caso de un hombre de 24 años que, secundario a un accidente de tránsito, presentó un traumatismo encefalocraneano grave con daño axonal difuso. Luego de un mes de evolución en la unidad de cuidados intensivos comenzó a presentar episodios súbitos de hipertensión, taquicardia, diaforesis, hipertermia, descerebración y dilatación pupilar, todo lo anterior con resolución espontánea en el curso de minutos. Estas crisis se repetían varias veces en el día. Se llegó al diagnóstico de un cuadro denominado Tormenta Simpática Paroxística que puede presentarse muy ocasionalmente como consecuencia de una lesión cerebral grave, especialmente el daño axonal postraumático. En este trastorno prima un desbalance simpático/parasimpático, lo que podría deberse a una pérdida del control cortical. El paciente fue tratado con opiáceos y betabloqueo con una respuesta satisfactoria, logrando disminuir significativamente sus episodios de tormentas simpáticas paroxísticas. En suma, nos parece importante comunicar esta experiencia dado la alta prevalencia de pacientes con trauma cerebral en nuestras Unidades de Pacientes Críticos. A pesar de que ni su diagnóstico ni tratamiento mejoran el pronóstico, su reconocimiento ahorra estudios innecesarios y permite iniciar una terapia sencilla que lleva al control precoz de la sintomatología.


A 24-year-old man suffered a traumatic brain injury due to a car accident. After one month of hospitalization in intensive care unit, he experimented episodic crisis of hypertension, tachycardia, hyperhidrosis, hypertermia, extensor posturing and pupil dilatation. This events presented in average 10 times per day. We reached to the diagnosis of Paroxysmal Sympathetic Storm. This is a subtype of dysautonomy which is present occasionally after a brain traumatic injury. The main mechanism of this brain dysfunction is a disassociation between the sympathetic and parasympathetic nervous systems due to cortical control loss. The patient was treated with morphine and labetalol and he experimented an excellent response, reducing his episodes of paroxysmal sympathetic storm by 80 percent. The aim of this review is to communicate this entity because a prompt and accurate diagnosis could minimize unnecessary studies and treatments.
