Introducción: El deterioro cognitivo (DC) es una enfermedad que aumenta con la edad. Es importante conocer los factores protectores y de riesgo de esta enfermedad. Metodología: Estudio observacional realizado a 729 personas mayores de 65 años en 13 farmacias comunitarias durante dos años. Se recogieron datos demográficos (sexo, edad, nivel de estudios) y de estilos de vida (afición a la lectura, realización de pasatiempos, horas de televisión) y para el cribaje de los pacientes se realizaron los test SPMSQ (Short-Portable Mental State Questionaire) de Pfeiffer y Mini-Mental State Examination (MMSE) versión NORMADERM. También se realizó una revisión bibliográfica del tema. Resultados: Se detectó un 17,6% de DC. Se encontró una asociación estadísticamente significativa como protección frente al DC con la afición a la lectura y el nivel de estudios. No se encontró asociación con las horas de televisión (TV) ni con la realización de pasatiempos. La revisión bibliográfica aportó más factores protectores y de riesgo. Discusión: Con nuestros datos podemos afirmar que tanto la reserva cognitiva (años de estudio) como la estimulación cognitiva (horas de lectura) protegen del DC. Sobre los demás datos obtenidos no se han encontrado coincidencias, por lo que sería necesario aumentar el tamaño muestral para poder realizar una comparación más eficaz. Conclusiones: El nivel educativo bajo es un factor de riesgo de DC, mientras que estudios superiores serían un factor preventivo. La lectura es un factor protector de DC. / Introduction: Cognitive Dysfunction (CD) is a disease that increases with age. It is important to know the protective and risk factors for this disease. Methodology: Observational study carried out on 729 people over 65 years of age in community 13 pharmacies for two years. Demographic data were collected (sex, age, level of studies) and lifestyles (love of reading, hobbies such as crossword puzzles or sudokus etc, TV hours), and the SPMSQ (Short-Portable Mental State Questionaire) test of Pfeiffer and Mini- Mental State Examination (MMSE) were carried out to check the patient’s CD. A bibliographic review of the subject was also conducted. Results: 17.6% of CD was detected. A statistically significant association was found as a protection against CD with a love of reading and the level of studies. No association was found with TV hours or hobbies. The literature review provided more protective and risk factors. Discussion: With our data we can affirm that both cognitive reserve (years of study) and cognitive stimulation (hours of reading) protect from CD. No coincidences were found on the other data obtained, so it would be necessary to increase the sample size in order to make a more effective comparison. Conclusions: Low educational level is a risk factor for CD while higher education would be a preventive factor. Reading is a protective factor of CD.

Purpose: The early detection of Mild Cognitive Impairment (MCI) is essential in aging societies where dementia is becoming a common manifestation among the elderly. Thus our aim is to develop a decision tree to discriminate individuals at risk of MCI among non-institutionalized elderly users of community pharmacy. A more clinically and patient-oriented role of the community pharmacist in primary care makes the dispensation of medication an adequate situation for an effective, rapid, easy, and reproducible screening of MCI. Methods: A cross-sectional study was conducted with 728 non-institutionalized participants older than 65. A total of 167 variables were collected such as age, gender, educational attainment, daily sleep duration, reading frequency, subjective memory complaint, and medication. Two screening tests were used to detect possible MCI: Short Portable Mental State Questionnaire (SPMSQ) and the Mini-Mental State Examination (MMSE). Participants classified as positive were referred to clinical diagnosis. A decision tree and predictive models are presented as a result of applying techniques of machine learning for a more efficient enrollment. Results: One hundred and twenty-eight participants (17.4%) scored positive on MCI tests. A recursive partitioning algorithmwith themost significant variables determined that the most relevant for the decision tree are: female sex, sleeping more than 9 h daily, age higher than 79 years as risk factors, and reading frequency. Moreover, psychoanaleptics, nootropics, and antidepressants, and anti-inflammatory drugs achieve a high score of importance according to the predictive algorithms. Furthermore, results obtained from these algorithms agree with the current research on MCI. Conclusion: Lifestyle-related factors such as sleep duration and the lack of reading habits are associated with the presence of positive in MCI test. Moreover, we have depicted how machine learning provides a sound methodology to produce tools for early detection of MCI in community pharmacy. Impact of findings on practice: The community of pharmacists provided with adequate tools could develop a crucial task in the early detection of MCI to redirect them immediately to the specialists in neurology or psychiatry. Pharmacists are one of the most accessible and regularly visited health care professionals and they can play a vital role in early detection of MCI.

Objetivo: desarrollar un programa de cribado de deterioro cognitivo (DC) en mayores de 50 años. Con la finalidad de que el servicio profesional farmacéutico sea más costo-efectivo utilizaremos un árbol de decisión para la selección del paciente. Además, se pretende valorar la importancia de la dieta mediterránea y el consumo de antioxidantes en la prevención del deterioro cognitivo y estudiar marcadores genéticos de riesgo de enfermedad de Alzheimer. Método: para ello se diseña un estudio observacional transversal mediante entrevista personal estructurada en pacientes que muestren indicios de pérdida de memoria. El estudio de captación se realizará en farmacias desde septiembre 2018 hasta septiembre de 2019. Los pacientes con puntuación en los test con posible DC se remitirán a atención primaria, previa presentación del proyecto a coordinación médica. Se perseguirá el resultado del diagnóstico obtenido en atención primaria y/o especializada. Se utilizarán como test de cribado el Memory Impairment Screening (MIS), Short Portable Mental State Questionnaire (SPMSQ) de Pfeiffer, el Fluidez Verbal Semántica (FVS) y siempre que sea posible el Test del Informador (TIN). Se define deterioro cognitivo por MIS ≤4; SPMSQ ≥ 3 (para analfabetos ≥ 4); FVS ≤10 palabras y el valor del TIN >57. A su vez se recogen una muestra de saliva del paciente, para estudio genético, y datos de nutrición para valorar la importancia de la dieta mediterránea y de los alimentos antioxidantes en la prevención del DC. / The aim of this study is to develop a screening program for cognitive impairment (CI) in people older than 50 year old. In order to make the pharmaceutical professional service more cost-effective, we will use a decision tree for patient’s selection. In addition, to assess the importance of the Mediterranean diet and the consumption of antioxidants in the prevention of cognitive deterioration and study genetic markers of risk of Alzheimer’s disease. A cross-sectional observational study is designed by a structured personal interview in patients showing signs of cognitive impairment. The recruitment study will be conducted in pharmacies from September 2018 to September 2019. Patients with a score on the tests with possible CI will be referred to primary care previous presentation of the project to the medical coordination. The result of the diagnosis obtained in primary and / or specialized care will be pursued. The Memory Impairment Test (MIS), the Short Portable Mental State Questionnaire (SPMSQ) of Pfeiffer, the Semantic Verbal Fluency (FVS) and, whenever possible, the Informer Test (TIN) will be used as screening tests. Cognitive impairment is defined by MIS ≤4; SPMSQ ≥ 3 (for illiterates ≥ 4); FVS ≤10 words. The value of TIN> 57. In turn, a sample of the patient’s saliva, for genetic study, and nutrition data are collected through a survey to assess the importance of the Mediterranean diet and antioxidant foods in CI prevention.
