  • Parkinson disease (PD) poses substantial management challenges owing to progressive disability and emergence of levodopa-resistant symptoms and treatment-related complications. This Review examines the current state of research into symptomatic and disease-modifying PD therapies and outlines future priorities for advancing our understanding and treatment of the disease.

    Review Article
  • In this Perspective, the authors present the Digitized Memory Clinic, a new framework for the diagnostic pathway of neurodegenerative dementias that incorporates digital health technologies with currently available assessment tools, such as fluid and imaging biomarkers, in an interplay with the physician.

    Perspective
  • A study in a mouse model of spinal cord injury helps to elucidate the neuroprotective mechanisms of autoimmune T cells during the early stages of injury, which could be harnessed through T cell therapy to improve long-term outcomes.

    Research Highlight
  • In this Perspective, the authors discuss how our understanding of coeliac disease could provide insights into the mechanisms of multiple sclerosis, the involvement of Epstein–Barr virus and the possibility of antiviral treatment against the virus as a therapy for multiple sclerosis.

    Perspective
  • Major advances have been made in disease-modifying therapies for multiple sclerosis, but people with Parkinson disease still lack such treatment options. Drawing on discussions from a symposium held in November 2022, this Roadmap proposes areas for exploration in Parkinson disease using lessons learned from therapeutic development in multiple sclerosis.

  • Peripheral organ dysfunction can have considerable effects on brain health, contributing to neurodegeneration and dementia. This Review explores how clinical and subclinical dysfunction of specific organ systems can impact brain health and discusses the implications for dementia prevention.

    Review Article
  • Traumatic brain injury can result in long-lasting symptoms and is associated with progressive neurodegenerative and neuroinflammatory pathology, but biomarkers to diagnose and monitor these chronic effects are lacking. Here, Thelin and co-workers summarize the available evidence for fluid biomarker use in chronic traumatic brain injury.

    Review Article
  • Although lecanemab has been licensed for use in the UK, the systems to deliver this or similar disease-modifying therapies do not exist. These systems need to be developed urgently, but not at the expense of post-diagnostic care.

    Comment
  • This Review summarizes the history and current concepts of neuromyelitis optica spectrum disorder (NMOSD) and myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD), including epidemiology, clinical and neuroimaging features and pathophysiology. It also discusses new molecularly targeted therapies for NMOSD that might be also applied to MOGAD in the future.
