Mild cognitive impairment (MCI), an intermediate stage between normal aging and dementia, has emerged as a prominent research area in geriatric care due to its heightened propensity for progressing toward dementia. Sleep plays a pivotal role in cognitive function, with dyssomnias not only exacerbating cognitive and affective symptoms associated with neurodegenerative diseases but also contributing to disease progression. <jats:italic>Aim<\/jats:italic>. This bibliometric analysis investigates the global research on MCI with dyssomnias over the past two decades, aiming to discern key findings, research domains, and emerging trends in this field. <jats:italic>Methods<\/jats:italic>. In this study, a bibliometric analysis was conducted using the search terms \u201cMCI\u201d and \u201csleep\u201d. Data were extracted from the Web of Science Core Collection database, and visualization and collaborative analysis were performed using CiteSpace and VOSviewer. <jats:italic>Results<\/jats:italic>. This study encompassed 546 publications from 2003 to 2023. The publication volume and citation rate consistently increased over time. Neurosciences, Clinical Neurology, and Geriatrics Gerontology emerged as the top three research fields. The <jats:italic>Journal of Alzheimer\u2019s Disease<\/jats:italic> had the highest publication count, while <jats:italic>Sleep Medicine<\/jats:italic> received the most citations. USA, China, and Italy led in publication output. Collaborative clusters among authors and institutions were identified, but cooperation between clusters was limited. Active cocited reference clusters included \u201cobstructive sleep apnea\u201d, \u201cpossible mediating pathways\u201d, and \u201cisolated rapid eye movement sleep behaviour disorder\u201d. The top frequently mentioned keywords, besides \u201cMCI\u201d, were \u201cAlzheimer\u2019s disease\u201d, \u201cdementia\u201d, \u201crisk factor\u201d, and \u201cParkinson\u2019s Disease\u201d. Notable keyword clusters spanned circadian rhythm, Parkinson\u2019s disease, MCI, dementia with Lewy body, subjective cognitive impairment, Lewy body disease, Alzheimer\u2019s disease, and dietary patterns. <jats:italic>Conclusion<\/jats:italic>. The field of MCI with dyssomnias is rapidly expanding, encompassing a wide range of neurodegenerative disorders and sleep disturbances. Current research endeavors are primarily focused on elucidating the underlying pathogenesis, predicting disease progression, and developing innovative treatment strategies for individuals affected by MCI with dyssomnias.<\/jats:p>","DOI":"10.1155\/2024\/6622212","type":"journal-article","created":{"date-parts":[[2024,1,6]],"date-time":"2024-01-06T12:35:05Z","timestamp":1704544505000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Knowledge
