EEG frequency bands in subjective cognitive decline: A systematic review of resting state studies.

As the older population continues to expand, there is a growing prevalence of individuals who experience subjective cognitive decline (SCD), characterized by self-reported failures in cognitive function and an increased risk of cognitive impairment. Recognizing that preventive interventions are typically more effective in preclinical stages, current research endeavors to focus on identifying early biological markers of SCD using resting-state electroencephalogram (rsEEG) methods. To do so, a systematic literature review covering the past 20 years was conducted following PRISMA guidelines, in order to consolidate findings on rsEEG frequency bands in individuals with SCD.

Online consultations in mental healthcare: Modelling determinants of use and experience based on an international survey study at the onset of the pandemic.

Introduction: While online consultations have shown promise to be a means for the effective delivery of high-quality mental healthcare and the first implementations of these digital therapeutic contacts go back nearly two decades, uptake has remained limited over the years. The onset of the COVID-19 pandemic dramatically altered this relative standstill and created a unique turning point, with a massive amount of both professionals and clients having first hands-on experiences with technology in mental healthcare.

Objective: The current study aimed to document the uptake of online consultations and explore if specific characteristics of mental health professionals across and beyond Europe could predict this.

Effects of psychological stress and cortisol on decision making and modulating factors: A systematic review.

Evidence suggests that psychological stress has effects on decision making, but the results are inconsistent, and the influence of cortisol and other modulating factors remains unclear. Based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria, 18 studies carried out between 2015 and 2020 that examined the effects of psychological stress on decision making and measured cortisol levels were selected. Eight studies employed uncertainty-based economic tasks, five studies used decision-making tasks in hypothetical situations that can be encountered in real life or in a specific setting and five studies employed prosocial decision tasks.

Effects of binge drinking and the anti-inflammatory drug indomethacin on spatial memory and cognitive flexibility in mice.

In previous research, we found that chronic-intermittent ethanol administration (CIEA), a model of binge drinking, impaired emotional memory in mice, and this impairment was counteracted by the anti-inflammatory drug indomethacin. In the present study, we evaluated the effects of CIEA on spatial memory and cognitive flexibility in adolescent mice of both sexes. Animals were randomly assigned to one of four groups for each sex: SS (saline + saline), SA (saline + alcohol), SI (saline + indomethacin), and AI (alcohol + indomethacin).

Online consultations in mental healthcare during the COVID-19 outbreak: An international survey study on professionals' motivations and perceived barriers.

Introduction: While the general uptake of e-mental health interventions remained low over the past years, physical distancing and lockdown measures relating to the COVID-19 pandemic created a need and demand for online consultations in only a matter of weeks.

Objective: This study investigates the uptake of online consultations provided by mental health professionals during lockdown measures in the first wave of the COVID-19 pandemic in the participating countries, with a specific focus on professionals' motivations and perceived barriers regarding online consultations.

Methods: An online survey on the use of online consultations was set up in March 2020.

Educational level as a protective factor against the influence of depressive symptoms on cognition in older adults: implications for functional independence during a 10-year follow-up.

Objectives: To examine whether the educational level moderates the relationship between baseline depressive symptoms and cognitive functioning at 5- and 10-year follow-ups in older adults, considering the association between cognitive functioning and difficulty with activities of daily living (ADL).

Design: Using a prospective design, a path analysis was performed.

Setting: In-home, face-to-face interviews and self-administered questionnaires, within the National Social Life, Health, and Aging Project.

Emotional memory impairment produced by binge drinking in mice is counteracted by the anti-inflammatory indomethacin.

The Binge Drinking (BD) pattern of alcohol consumption, prevalent in adolescents and young adults, has been associated with memory impairment. In addition, evidence shows that alcohol abuse causes neuroinflammation, which may contribute to the brain damage produced by alcohol and explain its cognitive consequences. In this study, we evaluated the effectiveness of the anti-inflammatory indomethacin in counteracting the memory impairment produced by alcohol (ethanol) in adolescent mice of both sexes.

An Animal Model of Alcohol Binge Drinking: Chronic-Intermittent Ethanol Administration in Rodents.

Binge drinking (BD), characterized by intermittent consumption of large quantities of alcohol in short periods of time, is the main alcohol consumption pattern in adolescents and young adults. BD has serious biomedical consequences, and it is a prominent risk factor for later development of alcohol use disorders. Rodent models offer exceptional power to study these negative consequences of BD.

Methods for Evaluating the Interaction Between Social Stress and Environmental Enrichment in Animal Models of Nicotine Addiction.

The environmental enrichment (EE) paradigm has been evaluated as a means of counteracting some of the consequences of chronic stress in rodents as well as a model of protective environment against drug abuse development. In the present chapter, our main aim is to describe the models of EE and chronic social stress and how they can be applied jointly in order to evaluate the effects of early psychosocial stress in animals exposed of different environments (enriched environment or standard environment). Furthermore, both paradigms could be applied in animal models of nicotine addiction, so the guidelines for the application of a chronic oral nicotine treatment in mice will be described.

Blood Alcohol Concentration-Related Lower Performance in Immediate Visual Memory and Working Memory in Adolescent Binge Drinkers.

The binge drinking (BD) pattern of alcohol consumption is prevalent during adolescence, a period characterized by critical changes to the structural and functional development of brain areas related with memory and cognition. There is considerable evidence of the cognitive dysfunctions caused by the neurotoxic effects of BD in the not-yet-adult brain. Thus, the aim of the present study was to evaluate the effects of different blood alcohol concentrations (BAC) on memory during late adolescence (18-19 years old) in males and females with a history of BD.

Hierarchical Status Predicts Behavioral Vulnerability and Nucleus Accumbens Metabolic Profile Following Chronic Social Defeat Stress.

Extensive data highlight the existence of major differences in individuals' susceptibility to stress [1-4]. While genetic factors [5, 6] and exposure to early life stress [7, 8] are key components for such neurobehavioral diversity, intriguing observations revealed individual differences in response to stress in inbred mice [9-12]. This raised the possibility that other factors might be critical in stress vulnerability.

Differential Effects of Alcohol on Memory Performance in Adolescent Men and Women with a Binge Drinking History.

Aims: Binge drinking (BD) is characterized by intermittent consumption of large quantities of alcohol in short periods. This pattern of drinking is prevalent among adolescents, and has been associated with undermined learning and memory ability. This study investigates the relationships between a history of BD and the effects of acute exposure to alcohol on learning and memory performance in adolescent men and women.

Indomethacin counteracts the effects of chronic social defeat stress on emotional but not recognition memory in mice.

We have previously observed the impairing effects of chronic social defeat stress (CSDS) on emotional memory in mice. Given the relation between stress and inflammatory processes, we sought to study the effectiveness of the anti-inflammatory indomethacin in reversing the detrimental effects of CSDS on emotional memory in mice. The effects of CSDS and indomethacin on recognition memory were also evaluated.

Effects of social stress and clomipramine on emotional memory in mice.

We have previously observed impairing effects of social defeat stress (CSDS) on inhibitory avoidance (IA) in mice. Given the similarity between changes produced by social stress in animals and symptoms of certain human psychopathologies such as depression and anxiety, the effects of the antidepressant clomipramine on IA impairment produced by CSDS were evaluated in the present study. Male CD1 mice were randomly assigned to the groups: non-stressed+saline, non-stressed+clomipramine, stressed+saline and stressed+clomipramine.

Effects of several degrees of chronic social defeat stress on emotional and spatial memory in CD1 mice.

In the present study, the effects of several degrees of CSDS (Chronic Social Defeat Stress) on emotional and spatial memory in mice were evaluated in separate experiments. Male CD1 mice were randomly assigned to four experimental groups (n=10-12) for each experiment: NS (non-stressed), S5, S10 and S20 (5, 10 and 20 sessions of CSDS, respectively). The S groups underwent the corresponding number of agonistic encounters (10min each) over a 20-day period.

Inhibitory avoidance learning in CD1 mice: Effects of chronic social defeat stress.

Chronic social defeat stress (CSDS) is an animal model widely used to determine the neurobiological mechanisms of stress and its associated pathologies. In this study, the effects of CSDS on inhibitory avoidance (IA) were evaluated in post-pubertal and adult male CD1 mice, instead of the C57BL/6J strain used in the CSDS standard protocol. CSDS consisted of daily 5-min (experiments 1 and 2) or 10-min (experiment 3) agonistic encounters on 21 consecutive days.
