Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder of upper and lower motor neurons that results in progressive motor impairment. ALS is the most common disease of motor neurons with an annual incidence of approximately 1.7–2.5 per 100,000 people. It is a ...

The Lumipulse G pTau217/ß-Amyloid 1-42 Plasma Ratio test, the first diagnostic blood test designed to aid in the evaluation of Alzheimer’s disease (AD), has been cleared by the US Food and Drug Administration (FDA). The Lumipulse G pTau217/ß...

Multiple sclerosis (MS) is a chronic neurological condition that often presents with vague or intermittent symptoms, making early recognition particularly challenging in primary care. As diagnostic delays can significantly impact long-term outcomes, timely identification and referral are critical. In alignment ...

In this Q&A, Dr Andy Liu, Associate Professor of Neurology at Duke University School of Medicine, discusses his presentation on the clinical use of lecanemab in Alzheimer’s disease. Drawing on real-world experience and findings from the 2022 CLARITY AD study, Dr Liu explores the treatment’s benefits, challenges in daily practice and the importance of patient-centred care in this evolving therapeutic landscape.

Watch a leading expert discuss the key signs and symptoms of Friedreich ataxia and how to avoid diagnostic delays.

Amyotrophic lateral sclerosis (ALS) is characterized by the degeneration of both upper and lower motor neurons, which ultimately leads to muscle weakness, atrophy, spasticity and contractures.1 ALS typically manifests in the 50–60 years age range, although familial cases may present in ...

touchNEUROLOGY is delighted to congratulate Dr Amit Bar-Or of Penn Medicine on receiving the 2025 John Dystel Prize for Multiple Sclerosis Research, jointly awarded by the National Multiple Sclerosis Society (NMMS) and the American Academy of Neurology (AAN). This honour recognizes his groundbreaking work in neuroimmunology, precision medicine, and biomarker research in multiple sclerosis (MS).

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.

New 48-week data from the ongoing Phase 3 KINECT 4 study evaluating valbenazine for the treatment of tardive dyskinesia (TD) have been presented at the 2025 Psychiatry Update Conference in Chicago. The finding showed the majority of participants reached a defined threshold for remission of TD regardless of underlying psychiatric disorder.
