The aim of this study was to analyse the role of the type of autobiographical memories reported by an individual reminiscence program to explain the decrease of depressive symptomatology found in elderly Portuguese people. A quasi-experimental design was used with pre- and post-test evaluations of the type of autobiographical memories. In this study, participants were 90 people over 65 years old with depressive symptoms, no antidepressive medication, and no signs of dementia. The participants were randomly assigned to one of three groups: experimental group (exposed to the program), control group or placebo-control group. The results of the study indicated that, in the participants of the experimental group, along with significant improvements in depressive symptomatology, significant increase in the number of specific autobiographical memories and positive autobiographical memories was recorded. The study also stresses the strong negative associations between depressive symptomatology and the specificity of the memories and their positive nature. The recovery and reconstruction of specific positive and negative autobiographical memories, using the reminiscence program, may be inherent to the reminiscence program developed that explain its efficiency as a therapeutic tool for psychological intervention aimed at the reduction of depressive symptomatology in old age.

Low and high glycemic index drinks differentially affect sleep polysomnography and memory consolidation: A randomized controlled trial.

Limited research has examined the effect of meal composition on sleep. Based on previous research, we hypothesized that a low glycemic index (LGI) drink containing 50 g isomaltulose (Palatinose, GI = 32) would result in more N3 sleep, less rapid eye movement (REM) sleep, and better memory consolidation than a high glycemic index (HGI) drink containing 50 g glucose (GI = 100). Healthy males (n = 20) attended the laboratory on three occasions at least a week apart (one acclimatization night and two test nights).

Background/objectives: Sexual minority older adults (SMOAs) report greater subjective cognitive decline (SCD) than heterosexual older adults (HOAs). This study aimed to compare the impact of multiple psycho-social risk factors on objective and subjective cognitive decline in HOAs and SMOAs.
Methods: Two samples of self-identified HOAs and SMOAs were selected from the English Longitudinal Study of Ageing.
Cognitive mechanisms of aversive prediction error-induced memory enhancements.

While prediction errors (PEs) have long been recognized as critical in associative learning, emerging evidence indicates their significant role in episodic memory formation. This series of four experiments sought to elucidate the cognitive mechanisms underlying the enhancing effects of PEs related to aversive events on memory for surrounding neutral events. Specifically, we aimed to determine whether these PE effects are specific to predictive stimuli preceding the PE or if PEs create a transient window of enhanced, unselective memory formation.

Mental imagery is claimed to underlie a host of abilities, such as episodic memory, working memory, and decision-making. A popular view holds that mental imagery relies on the perceptual system and that it can be said to be 'vision in reverse'. Whereas vision exploits the bottom-up neural pathways of the visual system, mental imagery exploits the top-down neural pathways.

Cerebral amyloid-beta (Aβ) accumulation, a hallmark pathology of Alzheimer's disease (AD), precedes clinical impairment by two to three decades. However, it is unclear whether Aβ contributes to subtle memory deficits observed during the preclinical stage. The heterogenous emergence of Aβ deposition may selectively impact certain memory domains, which rely on distinct underlying neural circuits.
