Setting: The study was conducted at the Instituto de Neurociencias de la Junta de Beneficencia de Guayaquil, a primary neuroscience institute in Ecuador.<\/jats:p><\/jats:sec><jats:sec><jats:title>Participants<\/jats:title><jats:p>The study evaluated 425 participants diagnosed with Mild Cognitive Impairment (MCI) or dementia, out of which 272 individuals (mean age = 75 years; 164 female) presenting specific medical conditions were selected for analysis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Measurements<\/jats:title><jats:p>Data were collected on demographics, medical history, and neuropsychological assessment using the Neuropsi scale. Conditions such as Type 2 Diabetes Mellitus, hypertension, obesity, and history of traumatic brain injury were specifically noted.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Latent Class Analysis identified three distinct classes of patients: Unspecified Cognitive Deterioration, Dementia, and MCI. The three-class model provided the best fit, revealing varied morbidity patterns and highlighting the influence of vascular and metabolic conditions on cognitive decline. Notably, similarities in hypertension and diabetes prevalence between Dementia and MCI classes suggested shared risk factors. The study also found no significant age differences between the classes, indicating that age alone might not be the primary determinant in the progression of cognitive decline.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The study underscores the complexity of dementia and MCI in an ageing Ecuadorian population, with vascular health playing a crucial role in cognitive impairment. These findings advocate for a holistic approach in managing dementia and MCI, emphasising the importance of addressing cardiovascular and metabolic health alongside neurocognitive care. The distinct morbidity patterns identified offer insights into tailored intervention strategies, highlighting the need for comprehensive, multidisciplinary care in dementia management.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fpsyt.2024.1432848","type":"journal-article","created":{"date-parts":[[2024,11,7]],"date-time":"2024-11-07T06:11:09Z","timestamp":1730959869000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":12,"title":["Multimorbidity patterns in dementia and mild cognitive impairment"],"prefix":"10.3389","volume":"15","author":[{"given":"Jos\u00e9 Alejandro","family":"Valdevila Figueira","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roc\u00edo","family":"Valdevila Santiesteban","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Indira Dayana","family":"Carvajal Parra","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luis Patricio","family":"Benenaula Vargas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andr\u00e9s","family":"Ram\u00edrez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jose E.","family":"Leon-Rojas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jose A.","family":"Rodas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,11,7]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"63","DOI":"10.1016\/j.jalz.2012.11.007","article-title":"The global prevalence of dementia: A systematic review and metaanalysis","volume":"9","author":"Prince","year":"2013","journal-title":"Alzheimer\u2019s Dementia"},{"key":"B2","unstructured":"Demencia\n          \n          \n          \n          2018"},{"key":"B3","doi-asserted-by":"publisher","first-page":"76","DOI":"10.1186\/s13195-019-0529-5","article-title":"The \u201crights\u201d of precision drug development for Alzheimer\u2019s disease","volume":"11","author":"Cummings","year":"2019","journal-title":"Alzheimers Res Ther"},{"key":"B4","unstructured":"Informe Mundial sobre el Alzheimer 2015: Las consecuencias de la demencia an\u00e1lisis de prevalencia, incidencia, coste y tendencias\n          \n          \n          \n          2015"},{"key":"B5","unstructured":"Perspectivas de la poblaci\u00f3n mundial 2019: metodolog\u00eda de las Naciones Unidas para las estimaciones y proyecciones de poblaci\u00f3n\n          \n          \n            \n              Cepal\n              N\n            \n          \n          \n          2020"},{"key":"B6","volume-title":"Neuropsicolog\u00eda de la enfermedad de Alzheimer","author":"Deus","year":"2018"},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.1186\/s12877-022-03066-8","article-title":"Predictivity of the comorbidity indices for geriatric syndromes","volume":"22","author":"Canaslan","year":"2022","journal-title":"BMC Geriatrics"},{"key":"B8","doi-asserted-by":"publisher","first-page":"05","DOI":"10.37387\/ipc.v6i2.84","article-title":"Deterioro cognitivo leve y depresi\u00f3n en el adulto mayor","volume":"6","author":"P\u00e9rez","year":"2018","journal-title":"Investigaci\u00f3n y Pensamiento Cr\u00edtico"},{"key":"B9","doi-asserted-by":"crossref","first-page":"165","DOI":"10.1001\/jama.2011.1964","article-title":"Association of incident dementia with hospitalizations","volume":"307","author":"Phelan","year":"2012","journal-title":"JAMA"},{"key":"B10","unstructured":"World population prospects: 2022 revision\n          \n          \n          \n          2022"},{"key":"B11","volume-title":"WHO methods and data sources for country-level causes of death 2000-2019","year":"2020"},{"key":"B12","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2318-13-2","article-title":"A survey-based study of knowledge of Alzheimer\u2019s disease among health care staff","volume":"13","author":"Smyth","year":"2013","journal-title":"BMC Geriatrics"},{"key":"B13","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(17)31363-6","article-title":"Dementia prevention, intervention, and care","volume":"390","author":"Livingston","year":"2017","journal-title":"The Lancet"},{"key":"B14","doi-asserted-by":"publisher","DOI":"10.1093\/ageing\/afr057","article-title":"Occurrence of medical co-morbidity in mild cognitive impairment: implications for generalisation of MCI research","volume":"40","author":"Stephan","year":"2011","journal-title":"Age Ageing"},{"key":"B15","doi-asserted-by":"publisher","DOI":"10.3233\/JAD-143078","article-title":"Mortality in mild cognitive impairment varies by subtype, sex and lifestyle factors.
