Introduction. The demographic and epidemiological transition, as well as the aging population has changed how older adults are treated in our healthcare system. Objective. To establish the sociodemographic and clinical characteristics of the patients from the Psychogeriatric Clinic (PC) of the Ramón de la Fuente Muñiz National Institute of Psychiatry (INPRFM) seen between January 1, 2011, and December 31, 2020. Method. Descriptive, observational, cross-sectional, retrospective study. A database was created with the information from digital clinical records. No additional scales were used. Statistical analysis performed in SPSS 20.0. Results. 2056 records were found, 1247 met the inclusion criteria. The mean age was 74.28 years, women 73.46% (n = 916), primary school 46.62% (n = 427), married 35.70% (n = 327), urban area 93.99% (n = 1172), home-based 78.28% (n = 717), low socioeconomic level 59.99% (n = 522). The most common psychiatric pathology was depressive disorders 62.07% (n = 774) and neurocognitive disorders 37.52% (n = 468) due to Alzheimer’s disease 17.08% (n = 213), with Mini-Mental State Examination of 18.88 points (± 6.68). They had comorbidities such as arterial hypertension 52.85% (n = 659), diabetes mellitus 23.34% (n = 291) and had a geriatric syndrome in 64.42% (n = 218). Discussion and conclusion. Aging in Mexico affects the female population the most. The analysis report from the prevalence for psychogeriatric pathologies of the PC it’s for of its kind. The main goal is promoting research on dementias and highlighting the magnitude of the problem for Latin American governments. The results are not intended to be extrapolated to the general population. [ABSTRACT FROM AUTHOR]

Objective: This study compares the efficacy of the AUDIT (gold standard) with the more easily and quickly applied instruments CAGE, TWEAK, and T-ACE for men aged ≥ 60 using data from a representative stratified sample of the general population of metropolitan São Paulo. Method: The GENACIS questionnaire was administered to a total sample of 2,083 people aged over 18, with a response rate of 74.5%. The elderly male sample consisted of 169 men. Sensitivity, specificity, positive and negative predictive values, area under the receiver operating characteristic curve, and confidence intervals were calculated for each instrument (95% CI). Results: Respondents were predominantly married (81.7%), had up to 11 years of education (61.3%) and a monthly per capita income of up to 300 US dollars. Current abstinence rate was high (61.6%) and 38% reported being former drinkers. There were no statistically significant differences among the instruments tested; however, the TWEAK had a higher area under the receiver operating characteristic curve (95% CI; 0.90-0.99). Conclusion: Research in the general population with screening instruments is scarce, especially among the elderly. However, it can provide specific information concerning this age group and be useful in the formulation of policies and prevention strategies. [ABSTRACT FROM AUTHOR]
