Special Issue Information

Dear Colleagues,

Spinal Muscular Atrophy (SMA) and Duchenne Muscular Dystrophy (DMD) are emblematic examples of the most extensively studied neuromuscular diseases in recent decades. The advent of antisense oligonucleotide (ASO)-based therapies designed to specifically target and modify RNA transcripts, as well as recently approved gene therapies, bring new challenges to the diagnosis and care of patients in both diseases.

The aim of this Special Issue is to share future avenues of research in the clinical diagnostic and therapeutic aspects as well as in the more basic mechanisms of SMA and DMD.

In SMA, several treatments have shown efficacy in stabilizing and even improving motor function, However, optimizing outcome in terms of age, respiratory status, severity, SMN2 copy number, and other variables remains to be established. Emerging phenotypes as well as combination therapies and outcome measures to assess efficacy, including biomarkers, should be assessed. In the meantime, patient care measures must continue to be discussed and improved.

In DMD, the panorama of new drugs in addition to standard corticosteroid therapy has shown a remarkable expansion. However, the true place of these new drugs in patient care and final outcomes needs to be clarified. We must understand phenotypic variability as well as determine the need and best timing of therapeutic care interventions such as bone care or hormone supplementation (to mention just a few examples). Given the new landscape, it is critical to develop physical assessment methods sensitive enough to detect clinically meaningful changes.

Papers dealing with some of the above-mentioned topics, other topics related to diagnostic, clinical, or therapeutic aspects of SMA or DMD, and basic research in this field are welcome.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
