ABSTRACT

INTRODUCTION Age-related cognitive disorders, including Alzheimer disease, are among the main causes of disability and dependence in older adults worldwide. High blood homocysteine levels (hyperhomocysteinemia) are a risk factor for diseases whose metabolism involves different B vitamins. Antioxidant vitamins provide a protective effect by mitigating oxidative stress generated by these diseases. Epidemiological studies have presented varying results on the relationships between blood levels of these vitamins and such cognitive disorders. OBJECTIVE Evaluate the association of vitamin and homocysteine levels with mild cognitive impairment and Alzheimer disease in a group of Cuban older adults. METHODS A cross-sectional study was conducted in Havana, Cuba, of 424 persons aged ≥65 years: 43 with Alzheimer disease, 131 with mild cognitive impairment, and 250 with no signs of cognitive impairment. Dementia was diagnosed using criteria of the International 10/66 Dementia Research Group and Diagnostic and Statistical Manual of Mental Disorders (DSM IV), and mild cognitive impairment was diagnosed using Petersen's criteria. Blood levels of vitamins (thiamine, B-2, folate, B-12, C and A) and homocysteine were measured by standard procedures. Analysis of variance for continuous variables and percentage comparison tests for dichotomous variables were used to compare groups. RESULTS Persons with Alzheimer disease presented signifi cantly lower levels of vitamins B-2, C and A than healthy participants (p <0.05). Homocysteine levels were signifi cantly higher in those with Alzheimer disease and mild cognitive impairment than in participants with no cognitive impairment (p <0.05). Statistically, levels of thiamine, folic acid, and vitamin B-12 were not signifi cantly different across groups. Compared with those without cognitive impairment, prevalence rates (PR) in the Alzheimer group were signifi cantly higher for hyperhomocysteinemia (PR = 3.26; 1.84-5.80) and defi - ciency of all B vitamins: thiamine (PR = 1.89; 1.04-3.43), B-2 (PR = 2.85; 1.54-5.26), folate (PR = 3.02; 1.53-5.95), B-12 (PR = 2.21; 1.17-4.19), vitamin C (PR = 3.88; 2.12-7.10) and A (PR = 5.47; 3.26-9.17). In mild cognitive impairment, prevalence rates were signifi cantly higher for hyperhomocysteinemia (PR = 1.42; 1.08-1.87), vitamin B-2 defi ciency (PR = 1.70; 1.24-2.32) and vitamin A defi - ciency (PR =1.88; 1.05-3.38). CONCLUSIONS Hyperhomocysteinemia and various vitamin defi ciencies are related to Alzheimer disease and mild cognitive impairment. Longitudinal studies are needed to further elucidate the relationship between different nutritional biomarkers and dementia. A better understanding of this relationship could provide a basis for therapeutic and preventive strategies. KEYWORDS Vitamins, homocysteine, geriatrics, Alzheimer disease, cognitive impairment, Cuba.

ABSTRACT

Introducción: la depresión en el anciano constituye un problema de salud. Los cambios biológicos, psicológicos, económicos y sociales que se observan en el proceso de envejecimiento, asociados a las numerosas patologías que aparecen en esta etapa de la vida, conllevan a pensar que irremediablemente los ancianos tengan todas las condiciones creadas para deprimirse.Objetivo: caracterizar la depresión en los adultos mayores y los tratamientos empleados para la misma, en la consulta de psicogeriatría y demencia de un policlínico.Métodos: se realizó un estudio descriptivo, retrospectivo de corte transversal a 112 ancianos, remitidos por los médicos de familia a la consulta de Psicogeriatría y Demencia del Policlínico "Cristóbal Labra", durante el período de julio a diciembre de 2011. Los datos se recogieron de las historias clínicas. Para el diagnóstico de la patología se aplicó el test de Yesavage y el Mini mental de Folstein.Resultados: la depresión se diagnosticó al 25 por ciento de los ancianos remitidos a consulta; la misma se incrementó con la edad, el bajo nivel educacional y la presencia de enfermedades como osteoartritis y alteraciones sensoriales. Los síntomas principales fueron los trastornos del sueño en el hombre y la tristeza y llanto en la mujer. Se usó la Medicina Natural Tradicional con éxito en un 42,9 por ciento de los ancianos.Conclusiones: la depresión es una entidad frecuente y poco diagnosticada, el uso de la Medicina Natural y Tradicional constituye una alternativa de tratamiento para la misma


Background: depression in the elderly is a health problem. The biological, psychological, economic and social changes seen in the aging process, associated to some pathologies appearing in this stage of life, inevitably lead to think that the elderly have created all the conditions to be depressed.Objective: to characterize depression in the elderly and the treatments followed for this condition in the Psychogeriatric and Dementia consultation at a polyclinic.Methods: a retrospective descriptive cross-sectional study was performed in 112 elderly who were referred by their family doctors to the Psychogeriatric and Dementia consultation of "Cristobal Labra" Polyclinic from July to December 2011. The data were collected from medical records. For the diagnosis of the pathology, the Yesavage and the Folstein Mini Mental tests were applied.Results: depression was diagnosed in a 25 per cent of the elderly who were referred to the consultation. This condition increased with age, low educational levels and the presence of diseases such as osteoarthritis and sensory changes. The principal symptoms were sleep disturbances in men and sadness and crying in women. Traditional Herbal Medicine was used which reported good results in a 42.9 per cent of the patients.Conclusions: depression is a frequent entity which is sometimes misdiagnosed. The use of Traditional Herbal Medicine constitutes an alternative treatment for it

ABSTRACT

Introducción: las demencias son enfermedades degenerativas que afectan a 35.6 millones de personas en el mundo y a más de 100 000 en Cuba; constituyen un acontecimiento vital estresante y hacen al anciano muy dependiente de otros y, por tanto, presa fácil de violencia. Objetivo: caracterizar los pacientes con demencia, según grupos de edades, sexo y nivel educacional, manifestaciones clínicas e identificar las conductas violentas, ejercidas sobre ellos, en la consulta de demencia y de terreno durante marzo a agosto de 2010. Material y Método: se realizó un estudio descriptivo desde el 1ero de marzo al 31 de agosto de 2010, en la consulta de demencia y/o en terreno pertenecientes al Policlínico Cristóbal Labra. La información se obtuvo mediante la aplicación de los siguientes instrumentos: Miniexamen del estado mental del anciano, criterios del DSM-IV, la escala de Zarit, Yasavage y la aplicación de una encuesta creada por la autora. Se utilizaron variables cuantitativas y cualitativas; los datos se recogieron en una planilla previamente diseñada y se procesaron de forma automatizada. Los resultados se mostraron en tablas y/o gráficos, y se calcularon medidas de resumen (frecuencias absolutas y porcentajes). Resultados: la demencia se relacionó con aumento de la edad, sexo femenino y menor grado de escolaridad. Los principales síntomas que generaron violencia fueron la pérdida de memoria e insomnio, predominó la Violencia Psicológica; las hijas fueron las principales maltratadoras. Conclusión: la demencia en adultos mayores constituyó un factor estresante generador de violencia en los cuidadores.


Introduction: the violence against the older persons is not a recent, it has been producing since many time ago, it real number is unknow. The dementia is a neurodegenerative disorders, already 35.6 millones of persons in the world and more of 100 000 en Cuba are afected by this pathology. The dementias are an important cause of violence because it produced a big uncapacity physical and intellectual. Objetives: caractherize pacient with dementia, by age, educacional level and sex, know mainly symptoms that produce violence in their mainly parent, diferents types of violences, principle clinical symptoms of psicologycal violence, persons responsible of injuries. Material and Methods: we made a descriptive estudies, since march 1er to agust 31, 2010 about the behavior of the violence on this kind of pacients and it relation with their parent. We used Minimental de Folstein, DSM-IV, Zarit, Yasavage test. Also we used the National Aging Resource Center of violence and the test made for the author. Results: dementias be increased in old patients, women were more afected, it incressed in patient with low educational level, symptoms more frequently found were: memory loss e insomny. The psychological violence was the principal type of violence found, the daughters had more violence behavior. Conclusion: the dementia on old persons produce a lot stress in persons that take care them.

ABSTRACT

We evaluated the psychometric properties of the 12-item interviewer-administered screener version of the World Health Organization Disability Assessment Schedule-version II (WHODAS II) among older people living in seven low- and middle-income countries. Principal component analysis (PCA), confirmatory factor analysis (CFA) and Mokken analyses were carried out to test for unidimensionality, hierarchical structure, and measurement invariance across 10/66 Dementia Research Group sites. PCA generated a one-factor solution in most sites. In CFA, the two-factor solution generated in Dominican Republic fitted better for all sites other than rural China. The two factors were not easily interpretable, and may have been an artefact of differing item difficulties. Strong internal consistency and high factor loadings for the one-factor solution supported unidimensionality. Furthermore, the WHODAS II was found to be a 'strong' Mokken scale. Measurement invariance was supported by the similarity of factor loadings across sites, and by the high between-site correlations in item difficulties. The Mokken results strongly support that the WHODAS II 12-item screener is a unidimensional and hierarchical scale confirming to item response theory (IRT) principles, at least at the monotone homogeneity model level. More work is needed to assess the generalizability of our findings to different populations.
