Relación entre la depresión y la demencia. Relationship between depression and dementia
The high association of depression and dementia in the elderly has motivated to investigate the type of relationship that exists between them. The objective of this narrative review was to describe the relationship between depression and dementia, for which the Medline, Science Direct, Dialnet, Redalyc databases were reviewed between 2000 and 2021, with the verbal descriptors “dementia” AND “depression” AND “relationship” AND “older adult” OUT “caregiver depression” to locate the candidate documents and then select the final sample made up of 60 published articles, which were reviewed by three judges for selection. Seven explanations of the relationship between dementia and depression were identified in which depression is considered a risk factor for dementia, a prodrome, a consequence, among others. Likewise, there was evidence that, although all the hypotheses have scientific support, there are also indications of their refutability. The types of relationship with the greatest scientific support were “depression as a risk factor” and “as a prodrome of dementia”, although the limitations in the studies prevent clarifying the relationship between these entities. Longitudinal studies that review the history of depression are suggested as a useful methodology to determine the relationship between them.

Prevalence Of Major Depressive Disorder In Portoviejo, Ecuador. Prevalencia del Trastorno Depresivo Mayor en Portoviejo, Ecuador.
Major depressive disorder (MDD) is a debilitating neuropsychiatric disorder that affects more than 300 million people, causing enormous socioeconomic burden. Little data has been known about prevalence of MDD in Ecuador. Thus, the aim of this study was to describe the prevalence of MDD in the population in a highly populated city in Ecuadorian Coast. This population-based study was accomplished in Portoviejo, Manabí. Here, we analyzed 114.239 records about MDD using Structured Clinical Interview for the Diagnosis of DSM-IV Disorders in younger, adults, and older peoples. We observed that the MDD score of 8.6% of the studied population. There was a suitable agreement between mild MDD and residence location scores (urban or rural zone). Both models had a good standard of fit (R2 = 0.91 and 0.95) and a mean p-value of 0.04 for both locations. A significant positive correlation between marital status and MDD scores, particularly for single (p = 0.001361, r = 0.94), and education levels (p = 0.00102, r = 0.95) was also demonstrated. Moreover, both age (p = 0.001067, r = -0.94) and widowed (p = 0.009662, r = -0.87) were negatively correlated with MDD scores. Collectively, our results revealed a high prevalence of MDD in the Portoviejo population, an effect more prominent in man, living alone, young and resident of the urban zone.

Tipificación del Trastorno Afectivo en Pacientes con Epilepsia del Lóbulo Temporal.
Introduction: Affective disorders in people with epilepsy seem to be different from patients with primary mood disorders.
Objective: to determine the clinical characteristics that typifies depression in patients with temporal Lobe Epilepsy.
Patients and methods: Forty patients with Temporal Lobe Epilepsy and depression were enrolled in the study. Thirty one patients with primary depressive disorder were recruited as control group. Depression was clinically evaluated in both groups. The discriminate analysis was used to determine the main clinical features of depression in patients with epilepsy. The differentiation between groups in total scores of Mood disorders through the International Psychiatry Interview was used to determine the atypical sign of depressive symptoms in patients with epilepsy. Logistic regression was utilized to analyze the possible relationship between neurobiological functioning and depressive symptoms in patients with epilepsy. Results: Sixty two percent of patients had a mood disorder not classified in CIE-10 and DSM-IV. Perictal anhedonia associated with insomnia, guilty thoughts, psychomotor slowness, inattention, restlessness, irritability, faintness became the clinical profiles of depression in patients with epilepsy. Age of onset of epilepsy, family history of psychiatric disorders, number of seizures per month, left temporal Lobe Epilepsy, and bilateral hippocampal atrophy were the most important determinants of mood disorders in our study.
Conclusion: Brief perictal depressive symptoms associated with dysphoria, anxiety and phobias, typify the clinical profile of depressive syndrome in patients with Temporal Lobe Epilepsy.

They suffer from a current illness (48%) and 62% presented the condition after caregiving. The regression model for anxiety included: negative impact, cognitive distancing, patient age and caregiver education. The depression model included: negative impact, caregiver education and cognitive distancing. Both explained 37% of variance.
Conclusions: Anxiety and depression depend on the skills and resources of the caregiver, the burden and impact of the disease. These correlate with physical, mental and socioeconomic issues that affect social relationships, intimacy and freedom of the caregiver.

El Estrés Crónico, ¿Factor de Riesgo para la Enfermedad de Alzheimer?
Alzheimer’s disease (AD) is a progressive neurodegenerative disorder, with epidemiological importance due to the high prevalence of people affected worldwide. Over time, various hypotheses have been raised in the pathophysiology and etiology of the disease and now the study of this disorder, is tackled from a multi-causal perspective, taking into account different etiological factors, among which are: genetics, oxidative stress, intracellular calcium dynamics, vascular effects, inflammation and stress, among others. The following literature review, aims to show studies that correlate stress as a risk factor in AD, recognizing the pathophysiological findings of AD, due to augmentation on glucocorticoids by chronic stress and the subsequent alteration of the hypothalamic-pituitary-adrenal axis. Critical view of these findings according to the literature.
