- Neuromyelitis optica spectrum disorders: A nationwide Portuguese clinical epidemiological studyPublication . Santos, E; Rocha, AL; Oliveira, V; Ferro, D; Samões, R; Sousa, P; Figueiroa, S; Mendonça, T; Abreu, P; Guimarães, J; Sousa, R; Melo, C; Correia, I; Durães, J; Sousa, L; Ferreira, J; de Sá, J; Sousa, F; Sequeira, M; Correia, AS; André, AL; Basílio, C; Arenga, M; Mendes, I; Marques, IB; Perdigão, S; Felgueiras, H; Alves, I; Correia, F; Barroso, C; Morganho, A; Carmona, C; Palavra, F; Santos, M; Salgado, V; Palos, A; Nzwalo, H; Timóteo, A; Guerreiro, R; Isidoro, L; Boleixa, D; Carneiro, P; Neves, E; Silva, AM; Gonçalves, G; Leite, MI; Sá, MJIntroduction: Neuromyelitis optica spectrum disorder (NMOSD) is a rare disorder in which astrocyte damage and/or demyelination often cause severe neurological deficits. Objective: To identify Portuguese patients with NMOSD and assess their epidemiological/clinical characteristics. Methods: This was a nationwide multicenter study. Twenty-four Portuguese adult and 3 neuropediatric centers following NMOSD patients were included. Results: A total of 180 patients met the 2015 Wingerchuk NMOSD criteria, 77 were AQP4-antibody positive (Abs+), 67 MOG-Abs+, and 36 seronegative. Point prevalence on December 31, 2018 was 1.71/100,000 for NMOSD, 0.71/100,000 for AQP4-Abs+, 0.65/100,000 for MOG-Abs+, and 0.35/100,000 for seronegative NMOSD. A total of 44 new NMOSD cases were identified during the two-year study period (11 AQP4-Abs+, 27 MOG-Abs+, and 6 seronegative). The annual incidence rate in that period was 0.21/100,000 person-years for NMOSD, 0.05/100,000 for AQP4-Abs+, 0.13/100,000 for MOG-Abs+, and 0.03/100,000 for seronegative NMOSD. AQP4-Abs+ predominated in females and was associated with autoimmune disorders. Frequently presented with myelitis. Area postrema syndrome was exclusive of this subtype, and associated with higher morbidity/mortality than other forms of NMOSD. MOG-Ab+ more often presented with optic neuritis, required less immunosuppression, and had better outcome. Conclusion: Epidemiological/clinical NMOSD profiles in the Portuguese population are similar to other European countries.

- Poster - ALTERAÇÕES NEUROPSICOLÓGICAS NA SÍNDROME DE SUSACPublication . Aguiar, S; Vieira, J; Morganho, A; Freitas, EA síndrome de Susac (SS) é uma endoteliopatia cerebral, da retina e ouvido interno. Na maioria dos casos descritos, as cefaleias precedem o desenvolvimento de outros sintomas clínicos . Podem ocorrer sintomas neurológicos adicionais, que incluem alterações na marcha, disartria e alterações cognitivas. No que respeita às alterações cognitivas, a literatura é escassa e pouco específica. Nos casos descritos, fala-se de uma forma geral em desorientação, perda de memória, alterações cognitivas ou demência 1-3.
- Poster - Casuistica dos doentes com esclerose multipla da consulta de doenças desmielinizantes do serviço de Neurologia do Hospital Dr. Nélio MendonçaPublication . Rodrigues, P; Aguiar, S; Morganho, A; Vieira, JA Esclerose Múltipla (EM) é uma doença inflamatória, caracterizada pela desmielinização e neurodegeneração no Sistema Nervoso Central1. Estima-se que em todo o mundo existam cerca de 2,5 milhões de pessoas com EM e em Portugal Continental estima-se que esta patologia atinja cerca de 6500 pessoas. Surge frequentemente entre os 20 e os 40 anos de idade e afeta mais mulheres do que homens (3 para 1). É em muitos países, a principal causa de incapacidade neurológica não traumática em adultos jovens1. As manifestações clínicas da EM variam desde alterações motoras, da sensibilidade, visuais, cognitivas, entre outras. A terapêutica utilizada para o tratamento desta doença tem como principal objetivo controlar a atividade da doença no sentido de atrasar a progressão da incapacidade dos doentes, a prevenção dos surtos e controlo dos sintomas. Neste trabalho temos como objetivo realizar uma análise retrospetiva de dados sociodemográficos (idade e sexo) e respetivo tratamento dos doentes Hospital Dr. Nélio Mendonça.
