BackgroundThe demographic and epidemiological transition, increased life expectancy and decreased fertility rate have increased the prevalence of dementia that affects 55 million people worldwide; it is estimated to affect 75 million by 2030 and increase three times by 2050. The clinical and sociodemographic characteristics of the studied population are unknown. It is the first study of its kind in the region. It’s also an unaddressed issue where an exploratory type protocol was carried out and a hypothesis was not formulated.MethodsDescriptive, observational, cross‐sectional, retrospective study. A Mexican population database including subjects from a previous work was created and then a secondary analysis was made. Every patient diagnosed with NCD was included regardless of age and with a clinical, psychiatric and/or geriatric syndrome diagnosis. No instrument or scale was used. There was no funding. Statistical analysis was done in SPSS 20.0.Results2056 records were found, 675 met the inclusion criteria. Age 74.71 (±9.02) years, from the urban area 93.78% (n = 633), women 72.15% (n = 487), primary school 49.90% (n = 243), widows 37.99% (n = 185), household occupation 77.21% (n = 376), low socioeconomic status 57.08% (n = 278). 59.86% (n = 404) had a major NCD, MMSE of 18.88 points (±6.68), Alzheimer’s disease was present in 31.56% (n = 213) both in those under 60 years of age 25.64% (n = 10) and in those older than 60 years old 31.92% (n = 203). Mild NCD was present in 9.19% (n = 62), the diagnosis was ruled out in 3.11% (n = 21) and a diagnosis could not be concluded in 25.93% (175). The most common psychiatric pathologies were Depressive and anxious disorder with 80.00% (n = 540) and 9.19% (n = 62) respectively; Clinical diagnosis were Arterial Hypertension 50.07% (n = 338), diabetes mellitus 22.22% (n = 150) and geriatric syndromes in 14.57% (n = 218).ConclusionThe study analyzes the characteristics of the clinic’s patients. The first of its kind which differentiates it from population based studies. The results are not intended to be extrapolated to the general population. Due to limitations in the diagnostic process of dementias, there were no diagnostic methods such as biomarkers in cerebrospinal fluid, functional or genetic neuroimaging. The intention is to promote dementia research and highlight the extent of the problem to Latinamerican Governments.

Introduction Posttraumatic stress disorder (PTSD) may develop after exposure to stressful or life-threatening events and is linked to suicidal behavior. Personality is hypothesized to be a mediator of this risk though assessing factors influencing such findings has been difficult due to the psychiatric comorbidities of the disorder. Objective The aim of the study was to examine the relationship between personality and suicidal behavior in people with PTSD. Method This was a cross-sectional study with 67 participants diagnosed with PTSD who completed a structured interview (SCID-II), and an inventory (NEO-FFI) to gather personality characteristics. Data were collected and analyzed through statistical software, and the investigation period ranged from August 2020 to July 2021. Results Extraversion was correlated with suicide attempts, borderline traits predicted the number of these, and a negative relationship was found between conscientiousness and the same variable. Schizotypal traits were also positively correlated to self-harm. Extraversion, schizoid, borderline, and obsessive-compulsive traits were more likely to be diagnosed with either depressive and/or anxious disorders. Extraversion’s association with suicidal attempts is inconsistent with previous studies, although the correlation of borderline traits with the same variable complies with existing knowledge. Schizotypal traits and their link with self-harm may be a novelty for this line of research, although the connection between extraversion, schizoid, borderline, and obsessive-compulsive traits along with depressive and anxious disorders echoes current literature. Conclusion Certain characteristics of personality are related to suicidal behavior in individuals with PTSD.

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.
