INTRODUCTION: Depression and Alzheimer's disease are both very frequent in elderly people. Cognitive deficits are the hallmark of Alzheimer's disease, but they are also common in depressed elderly people who often present cognitive deficits such as memory, attention and executive function problems. On the other hand, people with early Alzheimer's disease demonstrate emotional and behavioral disorders generally encountered in depression such as loss of energy, apathy, mood disorder, and irritability...

OBJECTIVE: Patients with depression show blunted amygdala hemodynamic activity to positive stimuli, including autobiographical memories. The authors examined the therapeutic efficacy of real-time functional MRI neurofeedback (rtfMRI-nf) training aimed at increasing the amygdala's hemodynamic response to positive memories in patients with depression. METHOD: In a double-blind, placebo-controlled, randomized clinical trial, unmedicated adults with depression (N=36) were randomly assigned to receive two sessions of rtfMRI-nf either from the amygdala (N=19) or from a parietal control region not involved in emotional processing (N=17)...

We currently know little about how performance on assessments of working memory capacity (WMC) that are designed to mirror the concurrent task demands of daily life are impacted by the presence of affective information, nor how those effects may be modulated by depression-a syndrome where sufferers report global difficulties with executive processing. Across 3 experiments, we investigated WMC for sets of neutral words in the context of processing either neutral or affective (depressogenic) sentences, which had to be judged on semantic accuracy (Experiments 1 and 2) or self-reference (Experiment 3)...

OBJECTIVE: Binge drinking is a significant public health problem across college campuses in the United States. Despite substantial research and the use of evidence-based methods, the binge drinking culture remains an obstinate health crisis on campuses. This study examined the current binge drinking rate on a selected college campus, the association between binge drinking and anxiety and depression as well as the associated consequences of students' alcohol use. METHODS: A sample of 201 students from a small, private Mid-Atlantic college completed validated scales as well as demographics and questionnaires...

An overly negative self-schema is a proposed cognitive mechanism of major depressive disorder (MDD). Self-schema - one's core conception of self, including how strongly one believes one possesses various characteristics - is part of semantic memory (SM), our knowledge about concepts and their relationships. We used the N400 event-related potential (ERP) - elicited by meaningful stimuli, and reduced by greater association of the stimulus with preceding context - to measure association strength between self-concept and positive, negative, and neutral characteristics in SM...

BACKGROUND: Three-quarters of patients with major depressive disorder have late-onset depression. Late-onset depression is more often associated with cognitive impairment than early-onset depression and evidences showed a relationship between vascular factors and late-life depression. OBJECTIVES: To compare cognitive functions between late-onset (≥60 years) and early-onset (<60 years) depression in elderly patients and to highlight the effect of vascular risk factors in elderly patients with late and early onset depression...

Seasonal affective disorder (SAD) is a recurrent major depressive disorder with a seasonal pattern, which is characterized by sad mood, low energy, longer sleep duration and carbohydrate craving. Furthermore, seasonal changes in mood and behavior may be closely related to alcohol use disorder (AUD). Nevertheless, there is scarce research on the study of cognitive impairments in SAD and AUD. We aimed to examine the relationship between the prevalence between SAD and AUD patients, and how cognitive functioning might be related to these variables...

BACKGROUND: Cognitive deficits have been identified as one of core clinical symptoms of major depressive disorder (MDD). Accumulating evidence indicated that triglycerides (TG) might be associated with MDD and cognitive decline. OBJECTIVE: This study examined whether patients with MDD had poorer cognitive functions than healthy controls, and further investigate whether TG levels were involved in MDD, and its cognitive impairments in a Han Chinese population. METHOD: 115 patients with MDD and 119 healthy controls were enrolled...

Recent research has implicated altered neural response to interpersonal feedback as an important factor in adolescent depression, with existing studies focusing on responses to feedback from virtual peers. We investigated whether depressed adolescents differed from healthy youth in neural response to social evaluative feedback from mothers. During neuroimaging, twenty adolescents in a current episode of major depressive disorder (MDD) and 28 healthy controls listened to previously recorded audio clips of their own mothers' praise, criticism and neutral comments...

BACKGROUND: Overgeneral autobiographical memory has been identified as a risk factor for the onset and maintenance of depression. However, little is known about the underlying mechanisms that might explain overgeneral autobiographical memory phenomenon in depression. The purpose of this study was to test the mediation effects of rumination on the relationship between overgeneral autobiographical memory and depressive symptoms. Specifically, the mediation effects of brooding and reflection subtypes of rumination were examined in patients with major depressive disorder...

Glutamate is the principal excitatory neurotransmitter in the central nervous system, and is thought to be involved in the process of memory encoding and storage. Glutamate disturbances have also been reported in psychiatric disorders, such as schizophrenia and major depressive disorder (MDD), and in Alzheimer's disease. In this paper, we set out to study the relationship between cerebrospinal fluid (CSF) glutamate levels and memory performance, which we believe has not been reported previously. In particular, we focused on recall performance broken down by serial position...

The microbiota is increasingly recognized for its ability to influence the development and function of the nervous system and several complex host behaviors. In this review, we discuss emerging roles for the gut microbiota in modulating host social and communicative behavior, stressor-induced behavior, and performance in learning and memory tasks. We summarize effects of the microbiota on host neurophysiology, including brain microstructure, gene expression, and neurochemical metabolism across regions of the amygdala, hippocampus, frontal cortex, and hypothalamus...

The introduction of allosteric receptor-receptor interactions in G protein-coupled receptor (GPCR) heteroreceptor complexes of the central nervous system (CNS) gave a new dimension to brain integration and neuropsychopharmacology. The molecular basis of learning and memory was proposed to be based on the reorganization of the homo- and heteroreceptor complexes in the postjunctional membrane of synapses. Long-term memory may be created by the transformation of parts of the heteroreceptor complexes into unique transcription factors which can lead to the formation of specific adapter proteins...

Human psychological stress is the major environmental risk factor for major depression and certain of the anxiety disorders. Psychological stressors often occur in the context of the adult social environment, and they or the memory formed of them impact on the individual across an extended period, thereby constituting chronic psychosocial stress (CPS). Psychosocial stressors often involve loss to the individual, such as the ending of a social relationship or the onset of interpersonal conflict leading to loss of social control and predictability...
