Achados otoneurológicos em pacientes com doença de Parkinson

Abstract

The number of elderly people is increasing considerably in our settings, and with that we have a matching increase in chronic-degenerative diseases -such as Parkinson's Disease (PD), which has balance-related symptoms associated and is increasingly more prevalent in the elderly population. Aim: Study labyrinth exams in PD patients and associate them with vestibular disorders. Study design: contemporary crosssectional cohort. Materials and Methods. Thirty patients were assessed, twenty females and ten males, at the age range of 48 -84 years. Procedures: anamnesis, ear inspection and vestibular assessment by means of a vecto-electronystagmography (VENG). Results: a) As to the neurotological complaints reported in the anamnesis, there was a prevalence of: tremor (100.0%), dizziness (43.3%), tinnitus (40.0%), gait unbalance and falls (36.6%) in each; b) in assessing the vestibular function, there was a significant difference in the rate of altered exams (p=0.0000); c) Most alterations happened in the peripheral vestibular system (93.3%) and the caloric test, with a predominance of bilateral labyrinth hyporreflexia (30,0%); d) The exam results were correlated with the vestibular symptoms and we noticed that there were no significant differences. Conclusion: this study showed us a significant number of altered exams, unrelated to symptoms.

Physical Equilibrium Evaluation in Parkinson Disease

“…As to the results of vectoelectronystagmograph, the biggest alterations are related to the research of postcaloric nystagmus, in which 5 (41.5%) of the patients had an altered result, 2 of whom (16.6%) were cases of directional prevalence. The findings of this study partially agree with BASSETO et al's reports (22), who found alterations in PD patients'' vestibular examination, which mostly occurred in the caloric test, however prevalently in the bilateral labyrinth hyporeflexia.…”

“…In the present research, among the 12 evaluated, 6 (50.0%) were found with an altered examination, and in a higher proportion the central vestibular syndrome. BASSETO et al (22), evaluating 30 PD patients, they observed the occurrence of nine cases of bilateral peripheral vestibular deficit syndrome; six cases of unilateral peripheral vestibular deficit syndrome; six cases of unilateral irritating peripheral vestibular syndrome; five cases of normal vestibular examination; two cases of bilateral irritating peripheral vestibular syndrome; one case of bilateral irritating central vestibular syndrome, and one case of bilateral central vestibular deficit syndrome.…”

Effect of caloric vestibular stimulation in a paraquat-induced parkinsonian mouse model

“…In PD patients, we notice a higher prevalence of tinnitus, tremor, gait unbalance, risk of falling and dizziness. In this context, the peripheral vestibular system and also the caloric test showed alterations (Bassetto et al, 2008). Pedunculopontine nucleus-thalamic controls the postural sensory integration in PD patients.…”
