Severe and unclassifiable tremor
Tremor grave e inclassíficávelAutor*innen
Abstract
Background Patients often exhibit very severe or disabling forms of tremor that cannot be clearly characterized.
Objective To present a series of 37 cases of tremor considered unclassifiable. Patients diagnosed with essential tremor according to criteria of the International Parkinson Disease and Movement Disorder Society (IPDMDS), who had been previously studied, were included as controls. All patients underwent a battery of tests between 2019 and 2022, which enabled us to compare them.
Methods Relevant demographic and clinical information were collected. The following tools were applied: the Mini-Mental State Examination (MMSE); the Hospital Anxiety and Depression Scale (HADS); the Fahn-Tolosa-Marín Tremor Rating Scale (TRS); and the Quality of Life in Essential Tremor (QUEST). A simple brain magnetic resonance imaging (MRI) scan was performed for all patients. The categorical variables were compared using the Chi-squared test and the t-test with Fisher correction if appropriate, and the quantitative variables were compared through the two-tailed Student t-test. Values of p ≤ 0.01 were considered statistically significant.
Results The cases presented higher scores on the anxiety and depression subscales of the HADS than the controls (p ≤ 0.006 and 0.000 respectively). In all domains of the TRS, the cases scored significantly higher, as well as in the QUEST. History of enolism was higher among the controls, and history of orthostasis and rest tremor was higher among the cases (p ≤ 0.000). Cerebellar atrophy was present in every patient in the case group, and in 24 subjects in the control group. Dystonia was observed in 7 subjects in the case group, and in none of the patients in the control group.
Conclusion There are patients with unclassifiable and extremely disabling tremors who respond poorly to the pharmacological therapy options.
Resumo
Antecedentes Os pacientes muitas vezes apresentam formas muito graves ou incapacitantes de tremor que não podem ser claramente caracterizadas.
Objetivo O objetivo deste trabalho foi apresentar uma série de 37 casos de tremor considerados inclassificáveis. Pacientes diagnosticados com tremor essencial de acordo com os critérios da International Parkinson Disease and Movement Disorder Society (IPDMDS), já estudados anteriormente, foram incluídos como controles. Todos os pacientes foram submetidos a exames entre 2019 e 2022 para permitir sua comparaç ão.
Métodos As informaç ões demográficas e clínicas relevantes foram coletadas. As seguintes ferramentas foram aplicadas: o Miniexame do Estado Mental (MEEM), a Escala Hospitalar de Ansiedade e Depressão (HADS, do inglês Hospital Anxiety and Depression Scale), a Escala de Avaliaç ão de Tremor de Fahn-Tolosa-Marín (TRS, do inglês Fahn-Tolosa-Marín Tremor Rating Scale) e a Qualidade de Vida em Tremor Essencial (QUEST, do inglês Quality of Life in Essential Tremor). Uma ressonância magnética simples do cérebro foi realizada em todos os pacientes. As variáveis categóricas foram comparadas pelo teste qui-quadrado e pelo teste t com correç ão de Fisher, se apropriado, enquanto as variáveis quantitativas foram comparadas por meio do teste t de Student bicaudal. Valores de p ≤ 0,01 foram considerados estatisticamente significativos.
Resultados Os casos apresentaram pontuaç ões maiores nas subescalas de ansiedade e depressão do HADS do que os controles (p ≤ 0,006 e 0,000, respectivamente). Em todos os domínios do TRS, a pontuaç ão dos casos foi significativamente maior, assim como no QUEST. O histórico de enolismo foi maior entre os controles e o histórico de ortostase e tremor em repouso foi maior entre os casos (p ≤ 0,000). A atrofia cerebelar foi apresentada por todos os pacientes do grupo de casos e em 24 indivíduos do grupo de controle. A distonia foi observada em sete indivíduos do grupo de casos e em nenhum dos pacientes do grupo controle.
Conclusão Há pacientes com tremores inclassificáveis e extremamente incapacitantes que respondem mal às opç ões terapêuticas farmacológicas.
