It remains unclear to what extent neurodegeneration in POAG extends to other neurological functions beyond vision, such as cognition. This follow-up study examined the potential association between POAG and cognitive decline in an African ancestry population. Methods: The Telephone-Montreal Cognitive Assessment (T-MoCA) was administered to POAG cases and controls previously enrolled in the Primary Open-Angle African American Glaucoma Genetics (POAAGG) study. Cases were assessed for retinal nerve fiber layer (RNFL) thickness and for the presence of dementia via chart review. Comparisons between POAG cases and controls were performed using two-sample t-tests for the T-MoCA total score and five subsection scores, and using chi-squared tests for incidence of dementia. Current scores were compared to scores from this same cohort from 7 years prior. Results: The T-MoCA was administered to 13 cases and 20 controls. The mean \u00b1 standard deviation (SD) T-MoCA total score was 15.5 \u00b1 4.0 in cases and 16.7 \u00b1 3.5 in controls (p = 0.36). However, there was a borderline significant difference in the delayed recall sub-score (2.3 \u00b1 1.6 for cases vs. 3.4 \u00b1 1.5 for controls, p = 0.052) and a significant difference in its sub-domain, the memory index score (MIS, 9.1 \u00b1 4.3 for cases vs. 12.1 \u00b1 3.0 for controls, p = 0.02). There were no significant differences between cases and controls for the remaining subsections. During 7 years of follow-up, a higher incidence of dementia was noted in POAG cases (7.1% for cases vs. 0% for controls, p = 0.058). Over 7 years, there was no significant deterioration in the cognitive performance of cases versus controls, and no association was seen between RNFL thinning and cognitive impairment. Conclusions: In this small-sample follow-up study of African ancestry individuals, POAG cases demonstrated worse short-term memory and higher incidence of dementia compared to controls. Future larger studies are needed to further investigate the presence and impact of neurodegeneration in POAG.<\/jats:p>","DOI":"10.3390\/jcm13144140","type":"journal-article","created":{"date-parts":[[2024,7,16]],"date-time":"2024-07-16T11:12:49Z","timestamp":1721128369000},"page":"4140","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Primary Open-Angle Glaucoma Is Associated with Short-Term Memory Decline and Dementia in Individuals of African Ancestry"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1689-2176","authenticated-orcid":false,"given":"Tzuriel","family":"Sapir","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, Scheie Eye Institute, University of Pennsylvania, Philadelphia, PA 19104, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrick","family":"Augello","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Scheie Eye Institute, University of Pennsylvania, Philadelphia, PA 19104, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roy","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Scheie Eye Institute, University of Pennsylvania, Philadelphia, PA 19104, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Makayla","family":"McCoskey","sequence":"additional","affiliation":[{"name":"TOC Eye and Face, Austin, TX 78705, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rebecca","family":"Salowe","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Scheie Eye Institute, University of Pennsylvania, Philadelphia, PA 19104, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Victoria","family":"Addis","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Scheie Eye Institute, University of Pennsylvania, Philadelphia, PA 19104, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Prithvi","family":"Sankar","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Scheie Eye Institute, University of Pennsylvania, Philadelphia, PA 19104, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gui-Shuang","family":"Ying","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Scheie Eye Institute, University of Pennsylvania, Philadelphia, PA 19104, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4109-2928","authenticated-orcid":false,"given":"Joan M.","family":"O\u2019Brien","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Scheie Eye Institute, University of Pennsylvania, Philadelphia, PA 19104, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,16]]},"reference":[{"key":"ref_1","unstructured":"GBD 2019 Blindness and Vision Impairment Collaborators, and on behalf of theVision Loss Expert Group of the Global Burden of Disease Study (2021).
