Special Issue Information

Dear Colleagues,

In recent years, our understanding of immune-mediated disorders affecting the pediatric nervous system has significantly evolved. From classical autoimmune encephalitides to novel neuroinflammatory syndromes, these conditions pose unique diagnostic and therapeutic challenges in children. Early recognition and appropriate treatment are critical for improving long-term outcomes, yet the heterogeneity in clinical presentation, biomarkers, and treatment responses demands a multidisciplinary approach. This Special Issue aims to bring together the latest advances in the field, including new insights into pathophysiological mechanisms, updates on diagnostic criteria, innovative immunotherapeutic strategies, and emerging biomarkers. Contributions will cover a broad spectrum of disorders such as autoimmune encephalitis, pediatric multiple sclerosis, MOGAD, neuromyelitis optica spectrum disorder, and parainfectious or post-vaccinal syndromes. We invite original research, case series, and reviews that enhance our understanding and management of immune-mediated neurological diseases in childhood, with the goal of supporting early diagnosis, precision treatment, and improved quality of life for affected patients.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Brain Sciences is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Acute disseminated encephalomyelitis (ADEM) is a rare, immune-mediated demyelinating disorder of the central nervous system (CNS) that predominantly affects children and young adults.

Acute disseminated encephalomyelitis (ADEM) is a rare, immune-mediated demyelinating disorder of the central nervous system (CNS) that predominantly affects children and young adults. ADEM typically follows an infectious or, less commonly, immunization-related trigger, and despite decades of clinical observation, its etiopathogenesis remains only partially understood. Clinically, the diagnosis of ADEM continues to pose significant challenges due to the absence of disease-specific biomarkers and its clinical and radiological overlap with other acquired demyelinating syndromes. This narrative review aims to summarize and critically discuss current knowledge on ADEM, with particular emphasis on its etiopathogenesis and clinical characteristics, highlighting the potential implications of recent research for clinical practice and management of this disease. Particular emphasis is placed on post-infectious immune mechanisms, including molecular mimicry, blood–brain barrier (BBB) disruption, loss of immune tolerance, and neuroinflammatory cascades. A wide spectrum of infectious triggers—viral, bacterial, parasitic—as well as post-vaccination, post-transplantation, paraneoplastic, metabolic, and host-related genetic factors are discussed in the context of immune dysregulation leading to CNS demyelination. We also highlight characteristic clinical and neuroimaging features that may aid in differentiating ADEM from other demyelinating syndromes, while acknowledging current diagnostic limitations. The integration of recent advances in ADEM immunopathogenesis with established clinical and radiological insights underscores the complexity of this disorder and highlights the evolving nature of current concepts regarding its diagnosis and clinical heterogeneity.
