Prevalence of and Factors Associated with Hypersexuality in Patients with Dementia: A Retrospective Cross-Sectional Study

Introduction: The psychological and behavioral symptoms of dementia are frequently observed in clinical practice, and those related to sexuality are particularly challenging. However, few studies have evaluated the prevalence or factors associated with hypersexuality in patients with dementia. Objectives This study aims to determine the prevalence of hypersexuality in patients with dementia, describe associated factors, and qualitatively report the most common presentations and treatments. Methods: This retrospective cross-sectional study collected data from semi-structured charts of dementia patients who were followed up at a secondary care reference center between 2015 and 2019. Results: Of 552 total patients, 52 (9.3%) were hypersexual, which was associated with male sex (P < .000; OR 2.95, 95% CI 1.73-5.01), frontotemporal dementia (P < .007), alcohol use (P < .015; OR 2.35, 95% CI 1.16-4.73) and tobacco use (P < .000; OR 2.88, 95% CI 1.61-5.13). Conclusions: Although our findings were similar to the literature, their significant variability reflects the limited and low quality of the available evidence and a lack of standardization regarding terminology, definitions, and diagnostic criteria for hypersexuality.
