RESUMEN
INTRODUCTION: The presence of cortical atrophy (focal or diffuse) prior to the development of symptoms of cognitive impairment could predict the earliest cases of neurodegenerative disease in patients with REM sleep behavior disorder (RSBD). We reviewed the usefulness of cranial CT and MRI as early markers of cortical atrophy in patients with RSBD at our center. PATIENTS AND METHODS: Retrospective observational descriptive analysis of patients diagnosed with RSBD from October 2012 to October 2022. All with cranial CT or MRI, evaluated by a neuroradiologist. RESULTS: 54 patients were included, 21 women (38.88%), 33 men (61.12%), mean age at diagnosis of RSBD: 69.04±12.625 years. Of the 54 patients, 44 (81.48%) had imaging tests consistent with their age, and 10 had atrophy greater than expected for their age. Of the 54 patients, 21 (38.88%) with a diagnosis of neurodegenerative disease, 33 (61.12%) persist as idiopathic, almost all with more than 5years of evolution (range of 1 to 10years of evolution without diagnosis). Of the 10 (18.52%) patients with greater atrophy, all were diagnosed with neurodegenerative disease (8 in 1year, 2 in 8years). CONCLUSIONS: Almost half of our series have developed a neurodegenerative disease in the first 10years of evolution. The majority of them presented global cortical atrophy measured by the GCA scale in the first year of diagnosis, without other neurological symptoms. Patients who did not show cortical atrophy at diagnosis have not yet developed the neurodegenerative disease in 10years of evolution. In our experience, the absence of cortical atrophy on cranial MRI or CT (measured by scales such as GCA) at the diagnosis of RSBD seems to predict slower progression cases. These data should be corroborated with larger series.

INTRODUCTION: REM sleep behaviour disorder (RBD) is characterised by violent behaviours (screaming, kicking, vivid dreams) during REM sleep. It has a prevalence of 1% to 2% of the general population and is especially frequent in men and the population older than 60. In the last decade, RBD has been suggested to be a prodrome of neurodegenerative disease. We analysed associated neurological diseases and responses to drug treatment in 33 patients with RBD treated in the multidisciplinary sleep disorders unit at Hospital Infanta Sofía. PATIENTS AND METHODS: We conducted an observational descriptive retrospective analysis of patients diagnosed with RBD and treated in our multidisciplinary sleep disorders unit between October 2012 and December 2015. We recorded age, sex, associated diseases, and treatments administered to these patients. RESULTS: A total of 365 patients were attended at our unit, including 33 with RBD: 13 women (40%) and 20 men (60%). Mean age was 62.72 years. An associated disorder was identified in 48%, with the most common being mild cognitive impairment (69%). The percentage of patients with RBD and an associated disorder among patients older than 60 was 68%. Eighty-two percent of the patients required treatment. The most commonly used drug was clonazepam (76%), followed by melatonin (9%), gabapentin (6%), and trazodone (3%). DISCUSSION: In our series, 48% of the patients had an associated disorder. The likelihood of detecting an associated disorder increases with patients' age. The vast majority of patients required drug treatment due to symptom severity; the most frequently administered drug was clonazepam (76%).

INTRODUCTION: Sleep disorders are highly prevalent among the general population, although very few cases of sleep apnoea-hypopnoea syndrome (SAHS) have been reported in patients with narcolepsy. This study reviews the sleep disorders found in patients with narcolepsy, the prevalence of SAHS associated with these patients and their response to the different treatments. PATIENTS AND METHODS: We conducted an observation-based retrospective descriptive analysis of 25 patients diagnosed with narcolepsy, who were treated in our centre between October 2012 and December 2016. RESULTS: Of 470 patients evaluated in the specialised neurology consultation unit, 25 patients were diagnosed with narcolepsy (5.31%); 65% were males and the remaining 35% were females; the mean age at the time of diagnosis was 40 years. 60% presented other associated sleep disorders, the most frequent being SAHS (36%). The efficacy rate of treatment with continuous positive airway pressure (CPAP) is 66% in patients with SAHS with an indication of CPAP. CONCLUSIONS: Altogether, 60% of patients with narcolepsy have a second associated sleep disorder (greater than the incidence of coexistence in the general population, of 20-25% of patients), and those reported are also the most frequent among the general population (SAHS, restless legs syndrome, periodic limb movement disorder). 36% of patients with narcolepsy have SAHS as an associated condition. Of these, 78% have reached a suitable degree of control over respiratory events; 57% have achieved control with CPAP, and the remaining 43% did not require CPAP for event correction with other methods.
TITLE: Sindrome de apneas-hipopneas y narcolepsia. Descripcion de una serie hospitalaria.Introduccion. Los trastornos del sueño son muy prevalentes en la poblacion general; sin embargo, la asociacion de sindrome de apneas-hipopneas (SAHS) en pacientes con narcolepsia se ha descrito en pocas ocasiones. Se revisan los trastornos del sueño encontrados en pacientes con narcolepsia, la prevalencia de SAHS asociado a estos pacientes y su respuesta a los tratamientos. Pacientes y metodos. Analisis descriptivo retrospectivo observacional de 25 pacientes, con diagnostico de narcolepsia, atendidos en nuestro centro desde octubre de 2012 hasta diciembre de 2016. Resultados. De 470 pacientes valorados en la consulta monografica de neurologia, hemos diagnosticado a 25 pacientes con narcolepsia (5,31%); el 65% eran hombres, y el 35%, mujeres. Edad media en el momento del diagnostico: 40 años. El 60% presenta otros trastornos del sueño asociados, el mas frecuente es el SAHS (36%). La eficacia del tratamiento con presion aerea positiva continua nasal (CPAP) es del 66% en los pacientes con SAHS con indicacion de CPAP. Conclusiones. El 60% de los pacientes con narcolepsia asocia un segundo trastorno del sueño (mayor que la incidencia de coexistencia en la poblacion general, del 20-25% de los pacientes), y los descritos tambien son los mas frecuentes en la poblacion general (SAHS, sindrome de piernas inquietas, movimientos periodicos de las piernas). El 36% de los pacientes con narcolepsia asocia SAHS. De ellos, en el 78% se ha conseguido un control de eventos respiratorios adecuado; el 57% se ha controlado con CPAP y el 43% restante no ha precisado CPAP por correccion de eventos con otros metodos.

Introducción: El trastorno de conducta de sueño REM (TCSR) se caracteriza por conductas violentas (gritos, patadas, sueños vívidos) durante la fase REM del sueño. Tiene una prevalencia del 1-2% de la población general, especialmente en varones y en mayores de 60 años. En la última década se ha asociado como pródromo a una enfermedad neurodegenerativa. Nos proponemos analizar las patologías asociadas a los 33 pacientes con TCSR atendidos en la Unidad Multidisciplinar de Trastornos del Sueño del Hospital Infanta Sofía, y su respuesta al tratamiento farmacológico. Pacientes y métodos: Análisis descriptivo, retrospectivo, observacional, de los pacientes con diagnóstico de TCSR, atendidos en la consulta monográfica de Neurología, desde octubre de 2012 hasta diciembre de 2015. Se valoran la edad, el sexo, las enfermedades asociadas, y los tratamientos empleados. Resultados: De los 365 pacientes valorados en la consulta, 33 presentan TCSR: 13 mujeres (40%) y 20 hombres (60%), con una edad media de 62,72 años. En el 48% se identifica una patología asociada: la más frecuente es el deterioro cognitivo leve (69%). El porcentaje de TCSR con patología asociada en mayores de 60 años se eleva al 68%. El 82% de los casos han requerido tratamiento. El fármaco más utilizado ha sido el clonazepam (76%), seguido de melatonina (9%), gabapentina (6%) y trazodona (3%). Discusión: En nuestra serie el 48% de los pacientes presentan una patología asociada. La mayor edad influye directamente en la posibilidad de encontrar una patología asociada. La gran mayoría han precisado tratamiento farmacológico por la severidad de los síntomas, siendo el clonazepam (76%) el fármaco más utilizado
