Prof. Amanda Piquet discusses the KYSA-8 miv-cel trial in refractory stiff-person syndrome, including efficacy findings, safety outcomes and the future role of CD19 CAR T-cell therapy in autoimmune neurologic disease. At the American Academy of Neurology Annual Meeting 2026, Prof. Amanda ...

Why this topic matters Autoimmune psychosis (AP) is conceptualized as a psychosis-dominant form of autoimmune encephalitis (AE). In contrast to ‘typical’ AE, in which seizures, impaired consciousness and focal deficits rapidly declare a neurological syndrome, patients with AP can initially ...

The late-breaking science sessions at AAN Annual Meeting 2026, Chicago, IL, USA brought together a wide range of pivotal and practice-shaping data spanning rare disease, neuroimmunology, headache, epilepsy, neurodegeneration and neuromuscular medicine. Several presentations reported positive phase III findings, while others ...

Over the past two decades, the understanding and management of multiple sclerosis (MS) have advanced dramatically, reshaping long-held views of the disease. MS is now increasingly seen as a continuous spectrum rather than a condition with distinct phases, with evidence showing it can begin silently, even before clinical symptoms emerge. Technological and diagnostic innovations have enabled the detection of early brain changes and biomarkers, opening doors to earlier diagnosis and intervention. New diagnostic criteria allow MS to be identified without a clinical event, and studies on disease-modifying therapies (DMTs) support the benefits of early treatment. A major shift in treatment strategy is also underway, emphasizing early, aggressive approaches and therapies that target progression rather than just relapses, which are no longer seen as the main driver of long-term disability. A pivotal development in MS research is the confirmation of Epstein–Barr virus (EBV) as a fundamental trigger of the disease, with new evidence pointing to specific viral protein regions as higher-risk factors. Despite these strides, MS research remains a dynamic and evolving field, with much still to be uncovered beneath the surface.

Neuromyelitis optica spectrum disorders (NMOSD) are a group of relapsing autoimmune diseases of the central nervous system. The clinical hallmarks of NMOSD are myelitis and optic neuritis; however, a wider clinical spectrum has been recognized.1 The majority of patients with ...

Case study Patient information A 42-year-old woman presented in the emergency department with acute onset whole-body myoclonic jerks for 1 day. On enquiry, the patient’s parents advised that she had a history of depression over the past 15 years. Intermittently, family ...

The 17th World Congress on Controversies in Neurology (CONy) took place March 23-25 2023 in Dubrovnik, Croatia. Prof. Amos D. Korczyn, CONy President (University of Tel-Aviv, Tel-Aviv, Israel) joined touchNEUROLOGY to discuss the main aims and focus of the recent CONy ...

Dr Michael Levy (Massachusetts General Hospital, Harvard Medical School, Boston, MA, USA) provides his highlights from the 75th AAN Annual Meeting, 2023, in particular that this was the first year to have a myelin oligodendrocyte glycoprotein (MOG) antibody disease focus, with ...

Acute disseminated encephalomyelitis (ADEM), first characterized in 1931,1 is a non-specific clinical syndrome of polyfocal central nervous system (CNS) inflammatory demyelination; it is characterized by encephalopathy and large, poorly demarcated cerebral white matter lesions.2,3 Myelin oligodendrocyte glycoprotein (MOG) antibody-associated disease (MOGAD), ...
