Contemporary Methods of Early Diagnosis of Neurological Diseases: International Research Experience

The significant increase in scientific papers reflects growing interest in the early detection of neurological diseases, driven by advances in neuroimaging, artificial intelligence and biomarker research. The overarching goal is to identify key trends and innovative methods that improve diagnostic accuracy and timeliness, thereby optimizing patient outcomes in the early stages of neurological diseases.This study analyzes 6132 publications in the Scopus database (1946-2024) related to the keywords “diagnosis” and “neurology”. The rapid growth in scientific output underscores an emerging focus on early detection of neurological disorders, facilitated by advancements in neuroimaging, artificial intelligence, and biomarker research. Research-oriented articles were selected based on the keywords “Diagnostics” and “Neurology,” and as a result, the 6132 selected scientific publications underwent statistical analysis using the SPSS program. The descriptive statistics method was used to study the dynamics of publications by year, leading countries, leading organizations, and major research areas.Analysis reveals a substantial rise in publications over the last decade, particularly in the fields of medicine, engineering, and computer science. The United States leads in overall output, followed by the United Kingdom and Germany. Collaborative, multidisciplinary research has contributed to emerging technologies ranging from advanced imaging modalities to AI-driven diagnostic tools that are increasingly crucial in detecting neurodegenerative and cognitive disorders at preclinical stages.A systematic review of publication activity highlights the growing global emphasis on early neurological diagnosis. Despite cost and accessibility challenges, integrating neuroimaging, AI systems, and biomarker technologies holds great promise for refining diagnostic precision, fostering international collaboration, and expanding the frontiers of neurological research.Keywords: neurology, early diagnosis, neuroimaging, biomarkers, Scopus, statistical analysis.
