Special Issue Information
Dear Colleagues,
Substance use disorders constitute a critical global health challenge. The term "substance", from the Latin "substantia", has evolved over time, with a variety of ontological (what is it?), epistemological (how can we know it?), and metaphysical (what role does it play?) implications. Within neuroscientific and medical contexts, “substances” refer to psychoactive agents that physiologically alter mental states, and these compounds have been studied progressively in relation to use disorders, distinguished between therapeutic, recreational, and pathological patterns. Understanding these conditions requires examination of the reward circuitry—particularly the mesolimbic dopaminergic pathways—and neuroadaptive mechanisms, including receptor desensitization, synaptic remodeling, and tolerance development.
Multidisciplinary investigation across molecular, cellular, and system levels reveals dysregulation of neurotransmitter systems, neuroplasticity, neuroinflammatory processes, and glial contributions within reward and executive control circuits. Interactions between genetic vulnerability, environmental factors, and disrupted prefrontal–limbic connectivity drive the transition from recreational to compulsive use. These insights inform therapeutic strategies, combining pharmacological interventions (agonists/antagonist therapies, novel agents targeting glutamatergic, neuroimmune/neuroendocrine pathways), neuromodulation, and biomarker-driven precision medicine, integrated with psychosocial interventions.
Nonetheless, critical challenges persist. Limited treatment efficacy and a high relapse rate reflect inadequate clinical translation. Advancing detailed mechanistic understanding may enhance personalized paradigms. Thus, the aim of this Special Issue is to bridge knowledge gaps through integrative translational frameworks addressing substance use disorders.
In this Special Issue, we invite submissions of original research manuscripts, reviews and meta-analyses, case reports, brief reports, opinions, and perspectives.

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-anonymized 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 2400 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.
