<dc:description>Introducción: Las ataxias (AT) y paraparesias espásticas hereditarias (PEH) son síndromes neurodegenerativos raros. Nos proponemos conocer la prevalencia de las AT y PEH en Espana˜ en&#xd;
2019.&#xd;
Pacientes y métodos: Estudio transversal, multicéntrico, descriptivo y retrospectivo de los&#xd;
pacientes con AT y PEH, desde marzo de 2018 a diciembre de 2019 en toda Espana. ˜&#xd;
Resultados: Se obtuvo información de 1933 pacientes procedentes de 11 Comunidades Autónomas, de 47 neurólogos o genetistas. Edad media: 53,64 anos ˜ ± 20,51 desviación estándar (DE);&#xd;
938 varones (48,5%), 995 mujeres (51,5%). En 920 pacientes (47,6%) no se conoce el defecto&#xd;
genético. Por patologías, 1.371 pacientes (70,9%) diagnosticados de AT, 562 diagnosticados de&#xd;
PEH (29,1%). La prevalencia estimada de AT es 5,48/100.000 habitantes, y la de PEH es 2,24&#xd;
casos/100.000 habitantes. La AT dominante más frecuente es la SCA3. La AT recesiva más frecuente es la ataxia de Friedreich (FRDA). La PEH dominante más frecuente es la SPG4, y la PEH&#xd;
recesiva más frecuente es la SPG7.&#xd;
Conclusiones: La prevalencia estimada de AT y PEH en nuestra serie es de 7,73 casos/100.000&#xd;
habitantes. Estas frecuencias son similares a las del resto del mundo. En el 47,6% no se ha&#xd;
conseguido un diagnóstico genético. A pesar de las limitaciones, este estudio puede contribuir&#xd;
a estimar los recursos, visibilizar estas enfermedades, detectar las mutaciones más frecuentes&#xd;
para hacer los screenings por comunidades, y favorecer los ensayos clínicos.</dc:description>
<dc:description>Introduction: Ataxia and hereditary spastic paraplegia are rare neurodegenerative syndromes.&#xd;
We aimed to determine the prevalence of these disorders in Spain in 2019.&#xd;
Patients and methods: We conducted a cross-sectional, multicentre, retrospective, descriptive study of patients with ataxia and hereditary spastic paraplegia in Spain between March&#xd;
2018 and December 2019. Results: We gathered data from a total of 1933 patients from 11 autonomous communities,&#xd;
provided by 47 neurologists or geneticists. Mean (SD) age in our sample was 53.64 (20.51)&#xd;
years; 938 patients were men (48.5%) and 995 were women (51.5%). The genetic defect was&#xd;
unidentified in 920 patients (47.6%). A total of 1371 patients (70.9%) had ataxia and 562 (29.1%)&#xd;
had hereditary spastic paraplegia. Prevalence rates for ataxia and hereditary spastic paraplegia&#xd;
were estimated at 5.48 and 2.24 cases per 100 000 population, respectively. The most frequent&#xd;
type of dominant ataxia in our sample was SCA3, and the most frequent recessive ataxia was&#xd;
Friedreich ataxia. The most frequent type of dominant hereditary spastic paraplegia in our&#xd;
sample was SPG4, and the most frequent recessive type was SPG7.&#xd;
Conclusions: In our sample, the estimated prevalence of ataxia and hereditary spastic paraplegia was 7.73 cases per 100 000 population. This rate is similar to those reported for other&#xd;
countries. Genetic diagnosis was not available in 47.6% of cases. Despite these limitations, our&#xd;
study provides useful data for estimating the necessary healthcare resources for these patients,&#xd;
raising awareness of these diseases, determining the most frequent causal mutations for local&#xd;
screening programmes, and promoting the development of clinical trials.</dc:description>
