Alterações dos potenciais evocados auditivos do tronco encefálico em pacientes com esclerose múltipla

Abstract

Al terations in early auditory evoked potentials (EAEP) in individuals with demyelinating disease are suggestive of lesions in the brainstem. Aim: this study aims to evaluate the prevalence of hearing disorders and altered EAEP in multiple sclerosis (MS) patients. Materials and method: sixteen female and nine male patients with a defined diagnosis of multiple sclerosis took part in this study. All individuals underwent hearing and EAEP tests. The wave forms were categorized according to Jerger (1986). Results: fifty EAEP tests were carried out; 70% were classified as type I (normal response) according to Jerger's criteria. Altered EAEP results in at least one ear were classified into types II, III, IV or V according to Jerger. Females accounted for 31.25% of alterations, and males 44.44%, adding up to 36% of all cases. Conclusions: these findings stress the importance of looking at EAEP in cases where there is suspicion of demyelinating disease and in patients with a defined diagnosis for MS.

Classical massage in multiplesclerosis.

“…(5,6,7) Characterized by multiple lesions limited in size, located exclusively in the white matter of the central nervous system (CNS), with disorderly spread, responsible for clinical polymorphism. (8,9) It mainly affects young adults, leading to the appearance of various signs and symptoms of impairment in motor areas, sensory, cerebellar and brainstem, sphincter and mental (10,11,12) in addition to evolve with motor, sensory, visual and coordination deficits, requiring special adjustments in the environment for patients continue with their activities (13,14) The health and well-being of these individuals may suffer severe impacts by the disease and/or side effects of medications, with significant interference in the quality of life of their patients. (15,16) Fatigue is a common and debilitating symptom of MS, and often has a negative impact on quality of life.…”

Potenciais evocados auditivos em doenças desmielinizantes na infância

“…Este dado corrobora o estudo realizado por Nuwer (1997) (Chiappa, 1997;Lima et al, 2009). (Rao et al, 1991;Fischer, 2001) indicaram disfunções cognitivas em 54 a 65% destes pacientes, sendo que os mesmos podem apresentar alterações na memória, atenção, fluência verbal, execução de tarefas e percepção visual.…”

Potenciais evocados auditivos de tronco encefálico e de longa latência em crianças com tronstornos do espectro do autismo

“…Desta forma, os PEA podem ser utilizados para avaliar o SNAC em diversos tipos de populações, tais como em indivíduos com transtornos psiquiátricos (Matas et al, 2009), com afasia (Alvarenga et al, 2005), com esclerose múltipla (Lima et al, 2009), com hipotireoidismo (Santos et al,2010) e, também, em crianças e adultos com autismo (Magliaro et al, 2010). No estudo de Matas et al (2009), verificou-se que indivíduos com autismo apresentaram alterações no exame do PEATE com estímulo clique, sugerindo comprometimento da via auditiva em tronco encefálico baixo, relacionadas principalmente a alterações da sincronia na geração e transmissão dos impulsos neuroelétricos ao longo da via auditiva em tronco encefálico.…”
