ABSTRACT

Background: Dementia is defined as the evidence of a significant cognitive decline compared to the previous level of performance in one or more cognitive domains.
Objective: To analyze the comorbidity in ambulatory patients older than 65 years with dementia.
Material and Method: A cross-sectional study was done in patients older than 65 years, taking the information from November 2016 to June 2017. Socio-demographic variables and comorbidity among elderly people with and without dementia were compared.
Results: 324 patients were analyzed, 206 (63.6%) women, mean age 81.2 ± 6 years, average schooling of 5.2 ± 4.0 years, 45 (46.87%) were married. The 96 (42.4%) subjects with dementia had a higher proportion of women: 52 (54.16%) vs 91 (40.26%), p ‹ 0.05. Cerebral vascular event was the only one of the comorbidities that showed a statistically significant difference with 22 (22.9%) vs 24 (10.6%), p ‹ 0.01. The factors associated with dementia were female sex (OR 1.79; 95% CI: 1.05-3.05; p ‹ 0.05) and cerebral vascular event (OR 3.4; 95% CI: 1.52-7.59; p ‹ 0.01).
Conclusion: Dementia is usually more common in older women. It is associated mainly with cerebral vascular events, without establishing a specific comorbidity relationship with the rest of the diseases analyzed.
