Tratamiento médico de la estenosis arterial intracraneal. ¿Es el mismo en prevención primaria que en secundaria?
In this study we review the risk factors associated with the formation and
progression of an atheroma plaque, the mechanism involved in cerebral ischemia
secondary to intracranial atheromatosis and possible medical treatment in primary
and secondary prevention. DEVELOPMENT: Medical treatment of intracranial stenoses
(ICS) is aimed at stopping the progression of the atheroma plaque and at
preventing recurrences in the case of symptomatic stenoses. It is based on the
control of vascular risk factors, the use of statins and antithrombotic therapy
(antiplatelet or anticoagulation drugs). Although antiplatelet agents have not
proved to be beneficial in the primary prevention of stroke, they are recommended
in patients with ICS in order to lower the risk of heart attack associated with
this pathology. The use of antiplatelet drugs in the secondary prevention of
ischemic stroke secondary to an ICS is based on clinical trials which have shown
that antiaggregation prevents non-cardioembolic strokes. Nevertheless, several
retrospective studies have observed that oral anticoagulation is better than
antiaggregation with aspirin. Two prospective clinical trials are currently being
conducted which will, in the next few years, help to determine what the first
choice medical treatment is for this group of patients. CONCLUSIONS: Medical
treatment of ICS patients must include the control of vascular risk factors and
the use of statins. New studies are needed to be able to establish the first
choice antithrombotic drug in secondary prevention

In recent years different studies have highlighted a
progressive increase in the demand for neurological
care in emergency departments. To analyze the
convenience of specific neurology shifts or the role that
the neurologist should play in the emergency
department, it is necessary to answer questions such
as: What is the demand for emergency neurological
care? What are the most frequent neurological
emergencies? Who should attend to neurological
emergencies and why? Are specific neurology shifts
necessary? Neurological emergencies account for
between 2.6% and 14% of medical emergencies. Stroke
represents a third of all neurological emergencies, while
the diagnoses of acute cerebrovascular disease,
epilepsy and cephalea constitute 50% of all neurological
care in the emergency department. On the basis of
quality of care criteria and professional competence, the
best care for patients with a neurological emergency is
provided by a specialist in neurology. The
implementation of specific neurology shifts, with a 24
hour physical presence, is associated with greater
quality of care, better diagnostic and therapeutic
orientation from the moment the patient arrives in
emergency department, reduces unnecessary
admissions, reduces costs and strengthens the
neurology service
Recomendaciones de uso de anticuerpos monoclonales para el tratamiento de la migraña del grupo de consenso de navarra y aragón
Sr. Editor:
La migraña es una patología neurológica que afecta al 14% de la población general (18% en mujeres); representa la segunda causa de discapacidad en el mundo en pacientes de mediana edad y genera importantes gastos socio-sanitarios1.
Las causas de la migraña no son bien conocidas pero existe una activación del denominado sistema trigémino-vascular (STV) que causa la liberación de diferentes mediadores proinflamatorios y vasodilatadores, entre los que destaca el péptido regulador del gen de la calcitonina (CGRP)2. El CGRP es un péptido que participa en la transmisión del estímulo doloroso, cuyos niveles se elevan durante las crisis de migraña y en el periodo intercrítico3.
El diagnóstico de la migraña es clínico y está basado en unos criterios de consenso que forman parte de la Clasificación Internacional de Cefaleas4. De forma general, la migraña se divide en migraña episódica (ME) y migraña crónica (MC). La ME es aquella en la que la cefalea aparece menos ..
Emotion Transfer for Hand Animation
We propose a new data-driven framework for synthesizing hand motion at different emotion levels. Specifically, we first capture high-quality hand motion using VR gloves. The hand motion data is then annotated with the emotion type and a latent space is constructed from the motions to facilitate the motion synthesis process. By interpolating the latent representation of the hand motion, new hand animation with different levels of emotion strength can be generated. Experimental results show that our framework can produce smooth and consistent hand motions at an interactive rate
Cefalea en urgencias
Headache is among the most frequent neurological
symptoms in the Emergency department. Although
most of the patients suffer from primary headaches
(migraine), an acute headache might be the only
symptom of a serious disease, such as subarachnoid
haemorrhage. The physician’s task is to make the
diagnosis, carry out an appropriate selection of the
patients who require further diagnostic evaluation and
relieve the pain. An accurate history will identify most
of the patients with secondary headaches. Clinicians
should suspect secondary causes in sudden onset
headache, headache in patients aged over 50 years, and
also in those patients with abnormalities on
neurological examination
Estimation of the Economic Burden and Labor Impact of Migraine in Spain: Results from the Spanish Atlas of Migraine Survey 2018
P170
Objectives: To estimate the average annual cost per patient and theimpact on work t of migraine in Spain.
Material and Method: This is a prospective, online, anonymous, cross-sectional survey, conducted between June and September2017, promoted by the Spanish Association of Patients with Headache(AEPAC) within the framework of the Spanish Atlas of Migraine2018. People who completed the survey answered questions in relationto their migraine. A distinction was made between chronic migraine(CM) and episodic migraine (EM), considering the monthlyheadache days declared by patients. The economic burden of migrainewas evaluated: direct health costs (including visits to specialists, medical tests, emergency visits, hospital admissions andmedication), indirect costs (lost labor productivity), and those assumedby the migraineur. The labor consequences of migraine overthe last year were analyzed. Chi-square and Mann- Whitney testswere used as contrast tests. Ethics Approval: A central ethics reviewboard approved the study design.
Results: 1, 281 people with migraine participated in the survey, 34.2%with CM, 88.2% women, with an average age of 37.3 (SD 11.5). Thedirect health costs for the last year were estimated at €3, 847.29 forCM and €964.19 for EM (p<0, 001). The costs assumed by the patientin the last year were €1, 609.89 for CM and €878.04 for EM (p<0.001).The indirect cost was estimated at €7, 464.83 for CM and €3, 199.15for EM (p <0.001). The total average cost per patient/year rised to€12, 922.01 for CM and €5, 041.41 for EM (p<0.001). Regarding the jobstatus: 62.2% with EM and 49.0% with CM were working, 2.6% withEM and 9.1% with CM were on sick leave and 12.2% with EM and16.8% with CM were unemployed (p <0.05). In the last year, becauseof migraine, 17.8% of patients with EM and 27.2% with CM (p<0.01)requested days of leave or leave of absence, and reduced their workinghours 8.5% with EM and 11.1% CM (p=0.270). Labor efficiencywas reduced in 61.1% of patients with EM and 65.7% with CM(p=0.257).
Conclusion: Migraine represents an important economic burden inSpain, particularly in patients with CM. Migraine causes importantproductivity losses resulting from absenteeism, presentism, decreasingthe working hours and the probabilities to keep working, and itsimpact is significantly greater in CM

Fisioterapia en cefalea tensional. ¿Debe recomendarse a nuestros pacientes?
La cefalea tensional es la patología neurológica más prevalente, y a pesar de su elevada frecuencia, la investigación en esta cefalea primaria es escasa, su fisiopatología es desconocida y el número de tratamientos médicos disponibles es muy limitado.
Por ello, resulta muy gratificante encontrar publicaciones de grupos españoles abordando el tratamiento de la cefalea tensional desde el punto de vista de la atención fisioterápica
Trastornos neuropsiquiátricos en la enfermedad de Parkinson
This paper reviews the main neuropsychiatric disorders associated with Parkinson’s disease (PD) and
describes the neuropathological hypothesis proposed to explain these symptoms. Development. This disease is usually associated
with neuropsychiatric complications such as depression, anxiety and apathy. Besides, psychiatric symptoms are one of the
most common side effects of antiparkinsonian drug-therapy. Conclusions. Depression is the most frequent emotional disorder
reported in patients with PD. Up to 20% of parkinsonian patients meet DSM-IV criteria for major depressive episode and another
20% for dysthymia, while the prevalence of depression in normal aged population is about 2-8%. The relationship between PD
and depression has not been fully established. Some investigators have suggested that depressive symptoms in PD are causally
related to the underlying neuropathological process, affecting predominantly serotoninergic and dopaminergic pathways.
Alternatively, depression in PD may represent a normal reaction to the progressive physical impairment induced by the disease.
Otherwise, up to 20% of parkinsonian patients present levodopa-induced psychiatric complications. Visual hallucinations are
the commonest, but delusions, confusional states, sexual disorders and sleep disorders have also been described. Serotonine and
dopamine have been implicated in the neuropathological basis of these disorders
