Depression in Alzheimer''s Disease: A Delphi Consensus on Etiology, Risk Factors, and Clinical Management

Background: Alzheimer''s disease (AD) and other forms of dementia are among the most common causes of disability in the elderly. Dementia is often accompanied by depression, but specific diagnostic criteria and treatment approaches are still lacking. This study aimed to gather expert opinions on dementia and depressed patient management to reduce heterogeneity in everyday practice. Methods: Prospective, multicenter, 2-round Modified Delphi survey with 53 questions regarding risk factors (11), signs and symptoms (7), diagnosis (8), and treatment (27) of depression in dementia, with a particular focus on AD. The questionnaire was completed by a panel of 37 expert physicians in neurodegenerative diseases (19 neurologists, 17 psychiatrists, and 1 geriatrician). Results: Consensus was achieved in 40 (75.5%) of the items: agreement in 33 (62.3%) and disagreement in 7 (13.2%) of them. Among the most relevant findings, depression in the elderly was considered an early sign (prodromal) and/or a dementia risk factor, so routine cognitive check-ups in depressed patients should be adopted, aided by clinical scales and information from relatives. Careful interpretation of neuropsychological assessment must be carried out in patients with depression as it can undermine cognitive outcomes. As agreed, depression in early AD is characterized by somatic symptoms and can be differentiated from apathy by the presence of sadness, depressive thoughts and early-morning awakening. In later-phases, symptoms of depression would include sleep-wake cycle reversal, aggressive behavior, and agitation. Regardless of the stage of dementia, depression would accelerate its course, whereas antidepressants would have the opposite effect. Those that improve cognitive function and/or have a dual or multimodal mode of action were preferred: Duloxetine, venlafaxine/desvenlafaxine, vortioxetine, tianeptine, and mirtazapine. Although antidepressants may be less effective than in cognitively healthy patients, neither dosage nor treatment duration should differ. Anti-dementia cholinesterase inhibitors may have a synergistic effect with antidepressants. Exercise and psychological interventions should not be applied alone before any pharmacological treatment, yet they do play a part in improving depressive symptoms in demented patients. Conclusions: This study sheds light on several unresolved clinical challenges regarding depression in dementia patients. Further studies and specific recommendations for this comorbid patient population are still needed.

Diagnosis and treatment of trigeminal neuralgia: Consensus statement from the Spanish Society of Neurology's Headache Study Group

Trigeminal neuralgia; Painful trigeminal neuropathy; Interventional radiologyNeuràlgia del trigemin; Neuropatia trigeminal dolorosa; Radiologia intervencionistaNeuralgia del trigémino; Neuropatía trigeminal dolorosa; Radiología IntervencionistaIntroducción La neuralgia del trigémino (NT) es un tipo de dolor neuropático que afecta a una o más ramas del nervio trigémino. Aunque su prevalencia poblacional es relativamente baja, la NT supone un problema muy importante tanto en las consultas de neurología como en las urgencias por la dificultad para el diagnóstico y el tratamiento y el elevado impacto sobre la calidad de vida de las personas que la padecen. Por estos motivos, el Grupo de Estudio de Cefaleas de la Sociedad Española de Neurología ha elaborado un documento de consenso sobre el manejo de esta patología. Desarrollo Este documento ha sido redactado por un comité de expertos utilizando la nomenclatura de la clasificación de la International Headache Society (IHS), analizando la evidencia científica publicada sobre diagnóstico y tratamiento y estableciendo unas recomendaciones prácticas con niveles de evidencia. Conclusiones El diagnóstico de la NT es clínico. La International Classification of Headache Disorders en su tercera edición (ICHD-3) clasifica el dolor atribuible a una lesión o enfermedad del nervio trigémino en NT y neuropatía trigeminal dolorosa. A su vez, la NT puede dividirse en tres tipos principales según la etiología del dolor: clásica, idiopática y secundaria. Es recomendable la realización de una resonancia magnética (RM) craneal a todo paciente con diagnóstico clínico de NT para descartar causas secundarias. Para estudiar la presencia de una compresión neurovascular con RM se recomienda la aplicación de los protocolos de imagen FIESTA, DRIVE o CISS. El tratamiento inicialmente será farmacológico. En pacientes seleccionados con respuesta insuficiente o mala tolerancia a fármacos se debe valorar el tratamiento quirúrgico.Introduction Trigeminal neuralgia (TN) is a chronic neuropathic pain disorder affecting one or more branches of the trigeminal nerve. Despite its relatively low global prevalence, TN is an important healthcare problem both in neurology departments and in emergency departments due to the difficulty of diagnosing and treating the condition and its significant impact on patients’ quality of life. For all these reasons, the Spanish Society of Neurology's Headache Study Group has developed a consensus statement on the management of TN. Development This document was drafted by a panel of neurologists specialising in headache, who used the terminology of the International Headache Society. We analysed the published scientific evidence on the diagnosis and treatment of TN and establish practical recommendations with levels of evidence. Conclusions The diagnosis of TN is based on clinical criteria. Pain attributed to a lesion or disease of the trigeminal nerve is divided into TN and painful trigeminal neuropathy, according to the International Classification of Headache Disorders, third edition. TN is further subclassified into classical, secondary, or idiopathic, according to aetiology. Brain MRI is recommended in patients with clinical diagnosis of TN, in order to rule out secondary causes. In MRI studies to detect neurovascular compression, FIESTA, DRIVE, or CISS sequences are recommended. Pharmacological treatment is the initial choice in all patients. In selected cases with drug-resistant pain or poor tolerance, surgery should be considered

Orthostatic headache and bilateral abducens palsy secondary to spontaneous intracranial hypotension

Spontaneous intracranial hypotension (SIH) is a well-documented syndrome characterized typically by a benign, self-limited course. Patients typically present with postural or exertional headaches that can be temporarily relieved by lying in a supine or recumbent position. A 35-year-old Caucasian male suffered orthostatic headache that developed to a bilateral abducens palsy. We ordered relative rest and the patient improved and completely recovered after 3 months. Although SIH is considered as a benign and self limited process it could also be associated with disabling complications. We should be aware of the possible complications and inform our patients. SIH can present with headache and bilateral abducens palsy even when the headache is improving

CGRP en migraña: de la fisiopatología a la terapéutica

Introducción En los últimos años se ha observado que moléculas como el péptido relacionado con el gen de la calcitonina (CGRP) y, en menor grado, el péptido activador de la adenilato-ciclasa pituitaria estaban elevadas durante los ataques de migraña y en la migraña crónica tanto en líquido cefalorraquídeo como en suero y que su reducción farmacológica tenía una significación clínica con una mejoría en la migraña de los pacientes. Es lógico por tanto que una de las principales líneas de investigación en migraña se base en el papel del CGRP en la fisiopatología de esta entidad. Desarrollo Desde el Grupo de Estudio de Cefaleas de la Sociedad Española de Neurología nos planteamos la redacción de este documento, cuyo objetivo es abordar, basándonos en la evidencia publicada, cuestiones tan importantes como el papel del CGRP en la fisiopatología de la migraña, el mecanismo de acción de los anticuerpos monoclonales y de los gepantes, el análisis crítico de los resultados de los diferentes estudios, el perfil del paciente que podría ser candidato al tratamiento con anticuerpos monoclonales y su impacto en términos de farmacoeconomía. Conclusiones El desarrollo clínico de los gepantes, antagonistas del CGRP, para el tratamiento agudo del ataque de migraña y de los anticuerpos monoclonales contra ligando y contra el receptor del CGRP ofrecen resultados esperanzadores para nuestros pacientes. Introduction It has been observed in recent years that levels of such molecules as calcitonin gene–related peptide (CGRP) and, to a lesser extent, the pituitary adenylate cyclase–activating peptide are elevated during migraine attacks and in chronic migraine, both in the cerebrospinal fluid and in the serum. Pharmacological reduction of these proteins is clinically significant, with an improvement in patients’ migraines. It therefore seems logical that one of the main lines of migraine research should be based on the role of CGRP in the pathophysiology of this entity. Development The Spanish Society of Neurology''s Headache Study Group decided to draft this document in order to address the evidence on such important issues as the role of CGRP in the pathophysiology of migraine and the mechanism of action of monoclonal antibodies and gepants; and to critically analyse the results of different studies and the profile of patients eligible for treatment with monoclonal antibodies, and the impact in terms of pharmacoeconomics. Conclusions The clinical development of gepants, which are CGRP antagonists, for the acute treatment of migraine attacks, and CGRP ligand and receptor monoclonal antibodies offer promising results for these patients

Secondary headaches: secondary or still primary?

The second edition of the International Classification of Headache Disorders makes a distinction between primary and secondary headaches. The diagnosis of a secondary headache is made if the underlying disease is thought to cause headache or if a close temporal relationship is present together with the occurrence of the headache. At first glance, this may allow clearly secondary headaches to be distinguished from primary headaches. However, by reviewing the available literature concerning several selected secondary headaches, we will discuss the hypothesis that some secondary headaches can also be understood as a variation of primary headaches in the sense that the underlying cause (e.g. infusion of glyceryl trinitrate [ICHD-II 8.1.1], epilepsy [7.6.2], brain tumours [7.4], craniotomy [5.7], etc.) triggers the same neurophysiologic mechanisms that are responsible for the pain in primary headache attacks

Italian guidelines for primary headaches: 2012 revised version

The first edition of the Italian diagnostic and therapeutic guidelines for primary headaches in adults was published in J Headache Pain 2(Suppl. 1):105–190 (2001). Ten years later, the guideline committee of the Italian Society for the Study of Headaches (SISC) decided it was time to update therapeutic guidelines. A literature search was carried out on Medline database, and all articles on primary headache treatments in English, German, French and Italian published from February 2001 to December 2011 were taken into account. Only randomized controlled trials (RCT) and meta-analyses were analysed for each drug. If RCT were lacking, open studies and case series were also examined. According to the previous edition, four levels of recommendation were defined on the basis of levels of evidence, scientific strength of evidence and clinical effectiveness. Recommendations for symptomatic and prophylactic treatment of migraine and cluster headache were therefore revised with respect to previous 2001 guidelines and a section was dedicated to non-pharmacological treatment. This article reports a summary of the revised version published in extenso in an Italian version
