However, uric acid can also exert beneficial functions due to its antioxidant properties, which may be particularly relevant in the context of neurodegenerative diseases. In this paper, we critically revise the evidence on the relationship between serum uric acid levels and cognitive function in older individuals, focusing on the etiology of cognitive impairment (Alzheimer\u2019s disease, Parkinson\u2019s dementia, and vascular dementia) and on the interactive connections between uric acid, dementia, and diet. Despite high heterogeneity in the existing studies, due to different characteristics of studied populations and methods of cognitive dysfunction assessment, we conclude that serum uric acid may modulate cognitive function in a different way according to the etiology of dementia. Current studies indeed demonstrate that uric acid may exert neuroprotective actions in Alzheimer\u2019s disease and Parkinson\u2019s dementia, with hypouricemia representing a risk factor for a quicker disease progression and a possible marker of malnutrition. Conversely, high serum uric acid may negatively influence the disease course in vascular dementia. Further studies are needed to clarify the physio-pathological role of uric acid in different dementia types, and its clinical-prognostic significance.<\/jats:p>","DOI":"10.3390\/nu10080975","type":"journal-article","created":{"date-parts":[[2018,7,27]],"date-time":"2018-07-27T12:20:03Z","timestamp":1532694003000},"page":"975","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":129,"title":["Uric Acid and Cognitive Function in Older Individuals"],"prefix":"10.3390","volume":"10","author":[{"given":"Claudio","family":"Tana","sequence":"first","affiliation":[{"name":"Internal Medicine and Critical Subacute Care Unit, Geriatric-Rehabilitation Department, Azienda Ospedaliero-Universitaria di Parma, 43125 Parma, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Ticinesi","sequence":"additional","affiliation":[{"name":"Internal Medicine and Critical Subacute Care Unit, Geriatric-Rehabilitation Department, Azienda Ospedaliero-Universitaria di Parma, 43125 Parma, Italy"},{"name":"Department of Medicine and Surgery, University of Parma, 43126 Parma, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Beatrice","family":"Prati","sequence":"additional","affiliation":[{"name":"Internal Medicine and Critical Subacute Care Unit, Geriatric-Rehabilitation Department, Azienda Ospedaliero-Universitaria di Parma, 43125 Parma, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2680-2242","authenticated-orcid":false,"given":"Antonio","family":"Nouvenne","sequence":"additional","affiliation":[{"name":"Internal Medicine and Critical Subacute Care Unit, Geriatric-Rehabilitation Department, Azienda Ospedaliero-Universitaria di Parma, 43125 Parma, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tiziana","family":"Meschi","sequence":"additional","affiliation":[{"name":"Internal Medicine and Critical Subacute Care Unit, Geriatric-Rehabilitation Department, Azienda Ospedaliero-Universitaria di Parma, 43125 Parma, Italy"},{"name":"Department of Medicine and Surgery, University of Parma, 43126 Parma, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,7,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2039","DOI":"10.1016\/S0140-6736(16)00346-9","article-title":"Gout","volume":"388","author":"Dalbeth","year":"2016","journal-title":"Lancet"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Tana, C., Busetto, M., Di Vincenzo, A., Ricci, F., Ticinesi, A., Lauretani, F., Nouvenne, A., Giamberardino, M.A., Cipollone, F., and Vettor, R.
