Despite the development of many new anti-seizure drugs over the past two decades, around one-third of individuals with epilepsy are without effective treatment. This pharmacoresistance is poorly understood, but new treatments targeting epileptogenesis instead of seizures have shown potential in animal models and are now being translated into the clinic.

Following extensive progress in the treatment of relapsing multiple sclerosis, the major challenge in the field is now to develop effective therapies for progressive forms of multiple sclerosis. As the first signs of success emerge, now is the time to consider the research needed to move the field forward.

The introduction of therapies for spinal muscular atrophy (SMA) has rapidly changed the clinical landscape, transforming SMA from a lethal to a treatable disease. This transformation has driven further advances, from population screening imperatives to novel treatment delivery approaches, while uncovering health disparities and fuelling debate regarding drug pricing.

Despite the strong treatment effects of mechanical thrombectomy in acute ischaemic stroke, penumbral tissue loss before recanalization and ischaemia–reperfusion injury after diminish functional outcomes and call for adjunct treatments. Classical neuroprotection strategies could consequently be revived, but novel treatment targets are also emerging through mechanistic research.

Despite negative findings from numerous clinical trials of potential disease-modifying therapies for Alzheimer disease, amyloid remains the most compelling therapeutic target. Advances in biomarker methods now enable accurate monitoring of Alzheimer disease progression from the earliest stages of the disease. We must therefore redouble efforts to find an effective treatment.

In current usage, ‘concussion’ describes a clinical presentation, but does not identify the underlying pathological process and therefore cannot be considered a true diagnosis. However, mounting evidence indicates diffuse axonal injury as a likely pathological substrate for concussion, thereby providing a framework to develop true diagnostic criteria.

After going virtual, the European Academy of Neurology 2020 Congress became the biggest neurology meeting in history. The overarching theme was ‘Time for action: predict, prevent, repair’ — three upcoming Reviews in Nature Reviews Neurology, written by speakers at the congress, highlight the importance of the theme across neurology.

The importance of reported neurological manifestations of coronavirus disease 2019 (COVID-19) is still unclear. Nevertheless, an immediate and ongoing neurological challenge posed by the COVID-19 pandemic is the management of patients who are undergoing immunotherapy for existing neuroimmunological disease.
