Neuropsychiatric disorders, encompassing conditions such as depression, schizophrenia, bipolar disorder, and Alzheimer’s disease, represent a leading cause of global disability. Despite significant research, their complex and often overlapping etiologies pose immense challenges for accurate diagnosis and effective treatment. Current diagnostic criteria largely rely on subjective clinical assessments, and many available therapeutics offer limited efficacy or carry substantial side effects. However, the convergence of advances in neuroscience, genomics, neuroimaging, and digital technology is fostering a transformative era. This Research Topic aims to capture and contribute to this momentum by exploring innovative, multidisciplinary strategies that promise to redefine our understanding and management of these debilitating conditions.

A critical problem in neuropsychiatry is the gap between the heterogeneity of clinical presentations and the relative imprecision of current diagnostic and therapeutic frameworks. This often leads to a trial-and-error approach to treatment, resulting in prolonged patient suffering and a significant socioeconomic burden. To address this, there is an urgent need to develop more objective biomarkers for early and differential diagnosis, alongside more personalized and targeted interventions. This Research Topic seeks to collate cutting-edge research that moves beyond traditional paradigms. We aim to showcase work on novel mechanisms, such as neuroinflammation or gut–brain axis modulation; innovative tools like AI-assisted digital phenotyping, advanced neuroimaging biomarkers, and wearable sensors; and new therapeutic modalities, including neuromodulation techniques, psychedelic-assisted therapy, and genetically informed pharmacotherapy. Our goal is to foster an integrative dialogue that accelerates the translation of laboratory discoveries into clinically actionable strategies, ultimately paving the way for more precise, effective, and accessible care for individuals with neuropsychiatric disorders.

This Research Topic welcomes original research, reviews, mini-reviews, perspectives, and clinical trial articles that focus on pioneering methodologies in neuropsychiatry. Specific themes of interest include, but are not limited to, the following:

1. Biomarker Discovery: Neuroimaging, electrophysiological, genetic, epigenetic, and proteomic biomarkers for diagnosis, prognosis, and treatment prediction.

2. Digital Psychiatry: Mobile health (mHealth) applications, digital phenotyping, passive sensing, and AI/machine learning for assessment and monitoring.

3. Novel Therapeutics: Targeted pharmacotherapy, neuromodulation (TMS, tDCS, DBS), psychedelic and entactogen research, psychotherapeutic innovations, and lifestyle interventions.

4. Mechanistic Insights: Research elucidating novel pathophysiological mechanisms (e.g., neuroimmune, mitochondrial, circadian) that inform new treatment avenues.

5. Precision Medicine Approaches: Strategies for patient stratification and personalized treatment selection.

We encourage submissions that are translational, data-driven, and have the potential to impact clinical practice.
