Research Landscapes and Gaps in Neuropsychiatric Assessment for Neurodegenerative Diseases: A Bibliometric Study on Huntington’s Disease, Amyotrophic Lateral Sclerosis, and Multiple System Atrophy

This study highlights the growing importance of NPSs in neurodegenerative diseases, particularly in HD, ALS, and MSA. We identify hotspots and deficiencies in the research field of validating NPS assessment tools, integrating NPSs into the diagnostic framework and elucidating neurobiological mechanisms. These findings will contribute to enhanced diagnostic and therapeutic approaches for neurodegenerative diseases.
