Resumen: Introducción: El conocimiento del alcance socioeconómico de las enfermedades que cursan con demencia es esencial para la planificación de recursos y la concienciación social. Desarrollo: Se ha realizado una revisión de los datos publicados hasta el momento sobre la epidemiología, morbilidad, mortalidad, discapacidad, dependencia e impacto económico de la demencia y la enfermedad de Alzheimer en España. Conclusiones: La mayoría de estudios en población mayor de 65 años estiman una prevalencia entre el 4% y el 9%. La prevalencia es mayor en mujeres en casi todos los grupos de edad. La enfermedad de Alzheimer es la causa de demencia más frecuente (50-70% del total). La demencia provoca un aumento de la morbilidad, mortalidad, discapacidad y dependencia de los pacientes, con una importante disminución de la calidad de vida y la supervivencia. El 80% de los enfermos es cuidado por sus familias, que asumen de media el 87% del coste total, con la consiguiente sobrecarga y menoscabo de la salud y calidad de vida de los cuidadores. El impacto económico de la demencia es enorme, y de evaluación compleja, por la mezcla de costes sanitarios y no sanitarios, directos e indirectos. Es necesario desarrollar programas globales e incrementar los recursos enfocados a fomentar la investigación, prevención, diagnóstico precoz, tratamiento multidimensional y abordaje multidisciplinario, que permitan reducir la carga sanitaria, social y económica de la demencia. Abstract: Introduction: Knowledge of the socioeconomic impact of dementia-related disorders is essential for appropriate management of healthcare resources and for raising social awareness. Methods: We performed a literature review of the published evidence on the epidemiology, morbidity, mortality, associated disability and dependence, and economic impact of dementia and Alzheimer disease (AD) in Spain. Conclusions: Most population studies of patients older than 65 report prevalence rates ranging from 4% to 9%. Prevalence of dementia and AD is higher in women for nearly every age group. AD is the most common cause of dementia (50%-70% of all cases). Dementia is associated with increased morbidity, mortality, disability, and dependence, and results in a considerable decrease in quality of life and survival. Around 80% of all patients with dementia are cared for by their families, which cover a mean of 87% of the total economic cost, resulting in considerable economic and health burden on caregivers and loss of quality of life. The economic impact of dementia is huge and difficult to evaluate due to the combination of direct and indirect costs. More comprehensive programmes should be developed and resources dedicated to research, prevention, early diagnosis, multidimensional treatment, and multidisciplinary management of these patients in order to reduce the health, social, and economic burden of dementia.

Resumen: Introducción: El uso de antidepresivos está muy extendido en la enfermedad de Parkinson (EP), aunque existen pocos estudios de calidad que aclaren su eficacia. Desarrollo: La metodología para esta guía clínica se ha basado en la revisión de la literatura y en la opinión de consenso del grupo de trastornos del movimiento de la AMN, recogida mediante una encuesta. Conclusiones: Según la evidencia científica, nortriptilina, venlafaxina, paroxetina o citalopram podrían ser utilizados en el tratamiento de la depresión en la EP, aunque paroxetina y citalopram con resultados contradictorios. Sin embargo, en la práctica clínica, los inhibidores selectivos de la recaptación de serotonina suelen ser los fármacos de primera elección. Por otro lado, aunque con menor evidencia, duloxetina podría ser una alternativa a venlafaxina y la asociación de venlafaxina con mirtazapina podría ser útil en casos refractarios. Además, podemos considerar el uso de citalopram para la ansiedad, atomoxetina para el tratamiento de la hipersomnia diurna, trazodona y mirtazapina para el tratamiento del insomnio y la psicosis, y bupropión para el tratamiento de la apatía. En general, los antidepresivos son fármacos bien tolerados en la EP. No obstante, es necesario considerar el efecto anticolinérgico de los tricíclicos, el efecto sobre la presión arterial de los inhibidores de la recaptación de serotonina y noradrenalina, la capacidad de los antidepresivos para desarrollar síntomas extrapiramidales y tener precaución con la asociación de inhibidores de la monoaminooxidasa B. Abstract: Introduction: Although antidepressants are widely used in Parkinson's disease (PD), few well-designed studies to support their efficacy have been conducted. Development: These clinical guidelines are based on a review of the literature and the results of an AMN movement disorder study group survey. Conclusions: Evidence suggests that nortriptyline, venlafaxine, paroxetine, and citalopram may be useful in treating depression in PD, although studies on paroxetine and citalopram yield conflicting results. In clinical practice, however, selective serotonin reuptake inhibitors are usually considered the treatment of choice. Duloxetine may be an alternative to venlafaxine, although the evidence for this is less, and venlafaxine plus mirtazapine may be useful in drug-resistant cases. Furthermore, citalopram may be indicated for the treatment of anxiety, atomoxetine for hypersomnia, trazodone and mirtazapine for insomnia and psychosis, and bupropion for apathy. In general, antidepressants are well tolerated in PD. However, clinicians should consider the anticholinergic effect of tricyclic antidepressants, the impact of serotonin-norepinephrine reuptake inhibitors on blood pressure, the extrapyramidal effects of antidepressants, and any potential interactions between monoamine oxidase B inhibitors and other antidepressants.
