The influence of MOGAD on diagnosis of multiple sclerosis using MRI
Myelin oligodendrocyte glycoprotein antibody-associated disease is an immune-mediated demyelinating disease that is distinct from multiple sclerosis but shares some of its characteristics. This Expert Recommendation, based on a Magnetic Resonance Imaging in MS workshop, proposes a diagnostic algorithm for the differential diagnosis of myelin oligodendrocyte glycoprotein antibody-associated disease and multiple sclerosis, using serological, imaging and clinical features.

Precision neuroimmunology in multiple sclerosis — the horizon is near
Immunological profiling has revealed biological signatures of multiple sclerosis (MS) that could help with early, accurate diagnosis of the disease and with identifying disease subtypes that could inform treatment decisions. The findings are important steps along the path towards precision medicine for people with MS.

Inflammasomes in neurological disorders — mechanisms and therapeutic potential
Increasing evidence suggests that inflammasome activation contributes to disease progression in a wide variety of neurological conditions. In this Review, Ravichandran and Heneka discuss current understanding of inflammasome activation in neurological disorders and consider interventional strategies that target inflammasome activation.

A tale of race and B cells in multiple sclerosis
A new study indicates that African American people with multiple sclerosis have higher markers of humoral disease pathology than white people with multiple sclerosis. However, apparent differences in pathophysiology between ethnic groups cannot be fully interpreted without more comprehensive studies that examine the effects of social inequality on disease.

Inverse association between age and inflammatory disease activity in multiple sclerosis
Two studies have confirmed previous observations that an inverse relationship exists between chronological age and focal white-matter inflammatory activity in individuals with multiple sclerosis, which could underlie the relative ineffectiveness of traditional disease-modifying therapies in older individuals.

New consensus guidelines on vaccination in multiple sclerosis
The European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) and European Academy of Neurology (EAN) joint consensus statement on vaccination in people with multiple sclerosis provides highly relevant clinical guidance on immunization strategies in today’s era of effective immunotherapies. Nevertheless, several open questions remain to be addressed.

Implications of immunometabolism for smouldering MS pathology and therapy
Smouldering inflammation encompasses all non-relapsing aspects of inflammatory pathobiology in multiple sclerosis. Here, Bittner and colleagues describe the mechanisms that underlie CNS-compartmentalized smouldering inflammation and review evidence indicating that immunometabolic reprogramming driven by the CNS tissue microenvironment shapes these inflammatory responses. Potential treatments are also discussed.

Bruton tyrosine kinase inhibitors for multiple sclerosis
Bruton tyrosine kinase inhibitors are an emerging treatment for multiple sclerosis. Krämer et al. consider the evidence that central nervous system-penetrant Bruton tyrosine kinase inhibitors might target both peripheral immune cells and compartmentalized inflammation and discuss promising preliminary results of clinical trials of these agents in multiple sclerosis.

A first step towards preventive medicine in multiple sclerosis
The results of the first randomized, placebo-controlled trial of dimethyl fumarate in a cohort of participants with radiologically isolated syndrome showed efficacy against the risk of a first clinical demyelinating event. The findings pave the way for preventive medicine in multiple sclerosis and highlight the need for more precise prognostication of risk.

Beyond ocrelizumab in primary progressive multiple sclerosis
Currently, the anti-CD20 monoclonal antibody ocrelizumab is the only approved treatment for primary progressive multiple sclerosis (PPMS). However, a new study suggests that other immunomodulatory disease-modifying therapies that are often used to treat relapsing forms of multiple sclerosis could be effective in people with PPMS who have evidence of active inflammatory disease.

The importance of getting evidence into practice
Neurological diseases cause a massive burden, which will increase as populations age. Rapid advances in our understanding of disease mechanisms must be translated into human benefits. We cannot stop once technologies have been developed, but must ensure that evidence and pipelines are in place for their implementation to reduce burden and inequalities.
