Abstract

In 2024, therapeutic and diagnostic advancements are shaping the field of neurology. Three new drugs show promise for treating myasthenia gravis and chronic inflammatory demyelinating polyneuropathy. A new classification for Parkinson's disease has been proposed, while a neuroprosthesis is improving gait in advanced stages. Revised criteria for inclusion body myositis and multiple sclerosis are refining diagnoses, and blood biomarkers are enabling early detection of Alzheimer's disease. The effectiveness of early thrombolysis in stroke has been confirmed, and new treatments are being explored for cerebral hemorrhages. In epilepsy, surgery reduces mortality by 30% in drug-resistant patients. Finally, new treatments targeting PACAP and CGRP are reducing refractory migraines with good tolerability., Competing Interests: le CHUV a reçu pour M. Théaudin : des honoraires de conférencière, des frais pour participation à des comités consultatifs et des subventions de voyage de la part d’Alexion, Argenx, Sanofi, Biogen, Roche, Novartis, CSL Behring, Merck, Alnylam et AstraZeneca.

Abstract

The year 2023 is marked by the arrival on the market of lecanemab for the treatment of Alzheimer's disease. New biomarkers have demonstrated their usefulness in monitoring peripheral neuropathies and diagnosing synucleinopathies. A genetic study has highlighted the role of nervous system cells in the risk of progression of multiple sclerosis (MS). The adverse effects of anticonvulsant treatments after prenatal exposure and on lipid metabolism have been clarified. New anti-CGRP treatments have demonstrated their efficacy in migraine attacks and chronic migraines. The criteria for thrombectomy have been further broadened. And finally, rehabilitation is refining the management of cerebrovascular patients and those with secondary progressive MS., Competing Interests: La Dre M. Théaudin a reçu des subventions de voyage et des honoraires de conférencière et de conseil de la part d’Alnylam, Sobi, Merck, Sanofi, Novartis et Biogen. Le Pr P.

Abstract

Neurocognitive disorders (TNC) are of a public health concern. An early and accurate diagnosis is important to tailor a personalised care. We illustrate the importance of a graduated etiological diagnostic approach centered on the clinical presentation employing the case of a patient with a progressive neurovisual disorder suggestive of a common form of Alzheimer's disease. The results of the CSF biomarkers analysis argue against this diagnosis and justifies seeking a Lewy body disease as a differential diagnosis even if all the clinical criteria are initially incomplete. In this article, we illustrate the progressive and graduated approach in the use of complementary medical tests available for reliable and early diagnosis in order to optimise the care plan and predict clinical progress and needs., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Abstract

The year 2022 was marked by the development of numerous new treatments for refractory myasthenia gravis. The link between epilepsy and cerebrovascular disorder was studied and lamotrigine discovered to be the optimal treatment choice for epilepsy secondary to stroke to prevent mortality on patient of 45 years and older. New randomized study finally demonstrated the utility of thrombectomy in selected patients with basilar artery occlusion. The causal relationship between Epstein-Barr infection and multiple sclerosis has been proved thanks to a large cohort study. A new possibility of subcutaneous continuous levodopa administration gave promising result. Finally, numerous studies confirmed the efficacy and excellent tolerability of anti-CGRP antibodies., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Abstract

Syphilis is a sexually transmitted disease which incidence increased over the last 10 years in Switzerland. The clinical and neurocognitive manifestations observed in case of symptomatic neurosyphilis can be very heterogeneous and can mimic neurocognitive disorders of other origins. This article discusses the diagnostic and management pitfalls in an older patient whose diagnosis of neurosyphilis was initially suspected during a home visit., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Abstract

Cerebellar ataxia can be caused by neoplasia, toxics (drugs, heavy metals, alcohol), infection, vascular lesions or auto-immune and paraneoplastic pathologies. Neuroimaging must be performed urgently in case of sudden onset and serologies as well as a lumbar puncture should be performed. Several case reports of ataxia associated with COVID-19 have been published, however the underlying pathogenic mechanisms remain unclear. This is a diagnosis of exclusion when other causes are ruled out and when the ataxia appears simultaneously to COVID-19 infection. We lack data on best management, but the prognosis appears mostly favorable with good functional recovery without any specific treatment. This paper describes the case of a patient who developed a cerebellar ataxia as the only neurological manifestation of a SARS-CoV-2 infection., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Abstract

In 2021, we assisted to the publication of new diagnostic criteria, classifications, and guidelines (CIDP, brain tumors, auto-immune encephalitis). Several studies helped to define the pharmacological management of focal and generalized epileptic seizures and epilepsy in pregnant women. The availability of biomarkers and the approval of immunotherapies are modifying the landscape of dementia management. Endovascular interventions without previous thrombolysis seems to be effective in anterior circulation acute ischemic stroke (AIS) and severe posterior circulation AIS. Neurologic complications of Sars-CoV-2 infection were further studied, as well as the efficacy of vaccines in immunosuppressed patients. New molecules and techniques show promising results for the treatment of migraine and cluster headache., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Abstract

Cognitive impairment can interfere with the fitness to drive. An increase in requests to assess this aspect is observed at Leenaards Memory Centre. Changes in the law could be an explanatory factor. The views formulated in 2019 are mainly unfavorable because all the patients present cognitive disorders, generally attributed to Alzheimer's disease or a related disorder, but never linked with aging only. Moreover, unfavorable views are frequently expressed before the age of 75. Therefore, each patient is unique, and each decision is based neither on the patient's age or his diagnosis, but rather on his cognitive profile. In this article we discuss the reasons for an unfavorable view and discuss them in the context of the tasks of our centre., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Abstract

Significant developments were published in 2020 in the field of blood biomarkers in Alzheimer's disease. Several studies helped to define more accurately the management of status epilepticus and of epilepsy in women of childbearing age. The new Swiss guidelines for the pre-hospital management of acute stroke were issued, as are new targets for stroke prevention. Numerous advances concerning the management of NMO-SD (NeuroMyelitis Optica Spectrum Disorder) were published. Different neurological presentations linked to the COVID-19 pandemic were described (central and peripheral). Several studies confirmed the effectiveness of new migraine treatments (including anti-CGRP). New pharmacological therapies are available for Parkinson's disease., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Abstract

Chemotherapy is associated with transient or permanent cognitive dysfunction ranging from subjective complaints to measurable deficits in working memory, attention and language. Given that old age may be related to cognitive decline, the interaction between chemotherapy-induced cognitive impairment and the effects of age is of growing concern in view of our aging population. Chemotherapy-associated cognitive dysfunction may have an additive impact on pre-existing age-related cognitive performance decline, which calls for awareness in its detection, to reduce impact on quality of life and improve management of older patients. We discuss here the « chemobrain », concept, review the existing evidence about pathophysiology, neuroimaging and cognitive phenotype and propose practical tools for routine detection in the outpatient setting., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Abstract

New studies confirm the possibility of late thrombolysis. Meta-analyses have confirmed that CGRP inhibitors are efficacious for migraines. Cladribine is a new oral treatment for relapsing-remitting multiple sclerosis. Limbic-predominant age-related TDP-43 encephalopathy (LATE) is a new clinical entity accounting for cognitive decline in old patients. The timing of levodopa introduction has no effect on the long-term course of idiopathic Parkinson's disease. Hypophosphatemia helps distinguish between seizures and syncopes in the emergency department. A second course of intravenous immunoglobulins provides no benefit for severe Guillain Barre syndrome. Outdoor therapy improves clinical scales in patients with disorder of consciousness. Ultrasound guided lumbar puncture improves the yield of the procedure., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Abstract

Thrombolysis and late thrombectomy can be performed in case of compatible radiological imaging. Anti-CGRP monoclonal antibodies seem more effective for the treatment of migraine. Siponimod can reduce significantly disability progression in secondarily progressive MS. Brand-to-generic levetiracetam switching does not cause recrudescence of epileptic seizures. A new definition of Alzheimer's disease using biomarkers of cerebrospinal fluid (CSF) and imaging provides a better understanding of the underlying mechanisms. The use of levodopa-carbidopa intestinal gel and a subcutaneous apomorphine infusion allow a reduction of motor fluctuations in Parkinson's disease.

Abstract

Stroke in the elderly has more major differences compared to young people. The first cause remains the atherothrombosis disease associated to the following risk factors: hypertension, diabetes, hypercholesterolemia, tobacco consumption. Lipohyalinosis of perforating arteries linked to blood hypertension inducing lacunar infarcts and atrial fibrillation are the 2nd and 3rd causes linked to age. The increase of the ageing population explains the rise of the number of stroke over 80 years. On a clinical point of view, the pseudo-bulbar syndrome is very frequent and explains the swallowing troubles and incontinence. Prognosis is characterized by a high risk of dementia (20 %). Primary and secondary prevention is very effective even in very old patients, on the risk of stroke. Fibrinolysis and stroke units have demonstrated their efficacy in stroke treatments over 80 years. We observed a decrease of case-fatality rates at any day with a delay in age of onset of stroke of 5 years in men and 8 years in women, suggesting an increase of life expectancy without stroke, reflecting a certain efficacy of prevention. The elderly may be more often included in therapeutic trials.

Abstract

The prevalence of bipolar disorders is about 4% of the population. Among the patients the emergence of cognitive disorders has been identified. These disorders can sometimes result in authentic dementia-like syndromes. The neuropsychological characteristics of the cognitive impairment include disorders of the steady attention, executive functions, memory and language. This group of cognitive disorders leads to a subcorticofrontal syndrome. Different neuroanatomical bases have been suggested. The most common etiopathogenic hypothesis retains a cumulative neurological toxicity of the thymic episodes (depression or mania). The role of psychoactive treatments must be taken into account. The secondary cognitive effects of psychoactive drugs usually used in bipolar disorder (lithium, antiepileptics, antidepressants, antipsychotics or tranquillizers) are similar to the cognitive impairment associated with the disease. Differentiation between cognitive disorders related to the pathology and those related to its treatment is difficult. The optimal use of the therapeutic drug classes, preferring antipsychotics of second generation and avoiding products with anticholinergic effect, is essential. There is no specific pharmacological treatment for this dementia syndrome. Psychological approaches offer an alternative way of care, which remains to be investigated and validated. Prevention of iatrogenic effects of drugs constitutes, presently, the main therapeutic intervention.

Abstract

With progress in stroke prevention it is important to evaluate epidemiological trends over a long period and in an unselected population. We estimated changes in stroke incidence, the case-fatality rate, risk factors, and the use of primary prevention, based on a continuous registry of a well-defined population, from 1985 to 2004. We recorded 3142 ischemic strokes, 341 primary cerebral hemorrhages and 74 subarachnoid hemorrhages. During the 20-year study period, age at first stroke increased by 5 years in men and 8 years in women. Comparing the periods 1985-1989 and 2000-2004, the age - and sex-adjusted incidence rates of first-ever strokes were stable, except for lacunar strokes, the incidence of which increased significantly (p = 0.05), and also cardio-embolic stroke, the incidence of which fell significantly (p = 0.01). Twenty-eight-day case-fatality rates fell significantly, especially for lacunar stroke (p = 0.05) and primary cerebral hemorrhage (p = 0.03). The frequency of hypercholesterolemia and diabetes increased significantly (p < 0.01). In contrast, the frequency of myocardial infarction fell significantly (p = 0.02). The frequency of smoking and diastolic blood pressure J 90 mmHg also fell, but the difference was not significant because of missing data. The frequency of pre-stroke antiplatelet and anticoagulant treatment increased significantly (p < 0.01). The age - and sex-adjusted incidence rates of stroke in Dijon, France, have thus been stable for the past 20 years. Age at stroke onset has increased, the case-fatality rate has fallen, antiplatelet treatment is more frequent, and the frequency of some pre-stroke risk factors has fallen.

Abstract

Introduction: Post-stroke depression is a severe complication affecting 30-50% of patients during the first year. Experienced medical and paramedical staff in stroke units, using validated scales, can now identify initial signs of depression in the first days after stroke onset., Methods: This review of the literature is based on a Medline search for the terms stroke, depression, and epidemiology. It discusses problems of pathophysiology, diagnosis, prognosis, and therapeutics., Results: Depression is an emergency in stroke patients because it impedes rehabilitation and family and social insertion. Early diagnosis is difficult, but possible with clinical somatic and cognitive symptoms. Post-stroke depression may also be a marker of pending cognitive decline. Management requires both antidepressants and psychotherapy., Conclusion: There is a pressing need for further research to improve clinical practice in this area of stroke care.

Abstract

Stroke in the elderly differs from stroke in younger adults in several points. It represents the most frequent consequence of atherothrombotic disease associated with hypertension, diabetes and hypercholesterolemia. It is also the main complication of cardiac arrhythmia. From a clinical point of view, epileptic seizure is frequently observed at the onset, and prognosis is darkened by a high risk of dementia occurrence (20%). Management of stroke in acute phase requires intensive care, which has been shown to decrease mortality and handicap by 20% in Stroke Units. Fibrinolysis with rt-PA can be carried out till 80 years. Primary and secondary prevention are still very efficacious in old patients and decrease not only the risk of stroke, but also the risk of dementia. Moreover, influenzae vaccination has been shown to decrease the risk of stroke in the following year in subjects over 65 years.
