RESUMEN
BACKGROUND: Functional motor disorders (FMD) are a frequent neurological condition affecting patients with movement disorders. Commonly described in younger adults, their manifestation can be also associated to an elderly onset. OBJECTIVE: To assess the prevalence and describe the clinical manifestations of FMD with elderly and younger onset and their relationship with demographical and clinical variables. METHODS: We recruited patients with a "clinically definite" diagnosis of FMD from the Italian Registry of FMD. Patients underwent extensive clinical assessments. For elderly onset, we set a chronological cut-off at 65 years or older according to WHO definition. Multivariate regression models were implemented to estimate adjusted odds ratio of elderly FMD onset related to clinical characteristics. RESULTS: Among the 410 patients, 34 (8.2%) experienced elderly-onset FMD, with a mean age at onset of 70.9 years. The most common phenotype was tremor (47.1%), followed by gait disorders, weakness, and dystonia (29.4%, 23.5%, 14.7%, respectively). Eleven elderly patients had a combined phenomenology: 9 exhibited two phenotypes, 2 had three phenotypes. Weakness was isolated in 3/8 patients and combined with another phenotype in 5/8, manifesting as paraplegia (n = 4); upper limb diplegia (n = 2), hemiparesis/hemiplegia (n = 1), and tetraparesis/tetraplegia (n= 1). Non-motor and other functional neurological disorders occurred more frequently in the younger group (89.1%) than the elderly (73.5%). Neurological and non-neurological comorbidities were more prevalent in the elderly group (82.4%) as opposed to the younger (32.7%). In a multivariate regression analysis, elderly-onset FMD was significantly associated with neurological comorbidities, including parkinsonism (OR 6.73) and cerebrovascular diseases (OR 5.48). CONCLUSIONS: These results highlight the importance of achieving an accurate diagnosis of FMD in the elderly, as it is crucial for effectively managing FMD symptoms and addressing neurological comorbidities.

RESUMO O objetivo deste estudo foi avaliar o desenvolvimento motor de crianças de quatro a 17 meses e investigar sua associação com fatores de risco sociodemográficos. Estudo transversal, descritivo, composto por crianças de quatro a 17 meses provenientes da unidade de internação pediátrica de um hospital público de Porto Alegre (RS), clinicamente estáveis e com alta breve prevista. Para a avaliação dos fatores de risco sociodemográficos foi utilizado um questionário elaborado pelas pesquisadoras, que abordou fatores biológicos, sociais e ambientais. Para a avaliação do desenvolvimento motor foi utilizada a Alberta Infant Motor Scale na versão traduzida, adaptada e validada para a população brasileira. Para a análise estatística foi utilizado o teste t de Student e o teste qui-quadrado, com nível de significância de 5% (p≤0,05). De um total de 110 crianças avaliadas, o desempenho motor se mostrou aquém do esperado em mais da metade delas (63,6%, n=70). Houve associação estatisticamente significativa entre o desenvolvimento motor e vacinas atrasadas (p=0,005), convivência com tabagistas em casa (p=0,047) e recebimento de benefício socioeconômico (p=0,036). Conclui-se que esses fatores sociais podem estar associados a fatores de risco ao desenvolvimento motor de crianças de quatro a 17 meses.
RESUMEN El presente estudio tuvo el objetivo de evaluar el desarrollo motor de niños de 4 a 17 meses de edad e investigar su asociación con factores de riesgo sociodemográficos. Es un estudio transversal, descriptivo, en el cual participaron niños de 4 a 17 meses de la unidad de hospitalización pediátrica de un hospital público en Porto Alegre (Brasil), clínicamente estables y con la espera de recibir el alta pronto. Para la evaluación de los factores de riesgo sociodemográficos, se utilizó un cuestionario desarrollado por los investigadores, que abordó los factores biológicos, sociales y ambientales. Para la evaluación del desarrollo motor, se utilizó la Alberta Infant Motor Scale en la versión traducida, adaptada y validada para la población brasileña. En el análisis estadístico, se aplicaron la prueba t de Student y la prueba chi-cuadrado, con un nivel de significación del 5% (p≤0,05). De 110 niños evaluados, más de la mitad de ellos (63,6%, n=70) tuvieron rendimiento motor inferior a lo esperado. Hubo una asociación estadísticamente significativa entre el desarrollo motor y las vacunas tardías (p=0,005), la convivencia con fumadores en el hogar (p=0,047) y el recibimiento de beneficios socioeconómicos (p=0,036). Se concluye que estos factores sociales pueden estar asociados con factores de riesgo para el desarrollo motor de niños de 4 a 17 meses.
ABSTRACT This study aimed to evaluate the motor development of children aged four to 17 months and investigate its association with sociodemographic risk factors. This is a cross-sectional descriptive study conducted with clinically stable children aged four to 17 months from the pediatric inpatient unit of a public hospital in Porto Alegre, RS, and whose hospital discharge would happen soon. For the evaluation of sociodemographic risk factors, a questionnaire developed by the researchers was used which addressed biological, social and environmental factors. The Alberta Infant Motor Scale (AIMS), in its version translated, adapted and validated to Brazilian Portuguese, was used in the evaluation of motor development. In statistical analysis, Student's t-test and Chi-square test were used with significance level of 5% (p≤0.05) for all tests. From a total of 110 evaluated children, motor performance was lower than expected in more than half of them (63.6%, n=70). Motor development presented statistically significant associations with delayed vaccines (p=0.005), cohabitation with smokers (p=0.047), and receiving socioeconomic benefits (p=0.036). In conclusion, social factors such as delayed vaccines, cohabitation with smokers and receiving socioeconomic benefits may be associated with risk factors related to motor development of children aged four months to 17 months old.
