Mild neurocognitive disorder (mNCD), a pre-dementia stage close to Cognitive Impairment, shows progressive and constant decline in the memory domain. Of non-pharmacological therapeutic interventions that may help decelerate neurodegenerative progress, transcranial direct current stimulation (tDCS) beneficial effects on learning curve, immediate recall, verbal executive functions. The purpose of this research was study effect tDCS general cognition, delayed functions by comparing an active...

There is no agreement on the pattern of recognition memory deficits characteristic patients diagnosed with mild cognitive impairment (MCI). Whereas lower performance in recollection hallmark MCI, there a strong controversy about possible familiarity estimates when using tasks. The aim this research to shed light responding and MCI. Five groups participants were tested. main participant samples those formed by two MCI differing age an Alzheimer's disease group (AD), which compared control...

Background: Transcranial direct current stimulation (tDCS) has emerged as a prevention method or minimizer of the normal cognitive deterioration that occurs during aging process. tDCS can be used to enhance functions such immediate memory, learning, working memory in healthy subjects. The objective this study was analyze effect two 20-min sessions anodal transcranial on learning potential, and older adults. Methods: A randomized, single-blind, repeated-measures, sham-controlled design used....

Objective:The retrieval deficit hypothesis states that the lack of in recognition often observed patients with Parkinson's disease is because low requirements task, given these have and not encoding deficits.To test this we investigated memory by familiarity Lewy Bodies Parkinson dementia.Method: We analyzed to what extent experimental groups were able recognize a typical yes/no task.The early nondemented disease, advanced demented patients, dementia Bodies.We compared their performance...

Aging is accompanied by an increase in false alarms on recognition tasks, and these with repetition older people (but not young people). Traditionally, this was thought to be due a greater use of familiarity people, but it recently pointed out that also have clear recollection component people. The main objective our study analyze whether the expected rate stimulus produced inadequate familiarity, recollection, or both processes. To do so, we carried associative experiment using pairs words...

Autobiographical memory (AM) presents components related to the type of and may present an associated emotional valence. Comparing healthy older adults, adults with mild cognitive impairment (MCI), Alzheimer's disease (AD) gives contradictory results. We examined AM in these groups analyze differences provide information that would contribute understanding deficits patients.31 AD, 32 MCI, were evaluated using Memory Test. Taking number memories elicited each category as a dependent variable,...

The aim of our experiment was to analyse the effect emotional valence (positive, negative, or neutral) on true and false recognition, matching arousal, frequency, concreteness, associative strength study recognition words. Fifty younger adults 46 healthy older performed three tasks (with words different valence: positive, their corresponding tests. Two weeks later, they tests again. results show that with a negative produced less than positive neutral valence, in both adults, immediate test....

We explore familiarity-based recognition using a paradigm devised by Parkin et al. (2001). The task consists of the creation two lists words written with one different subsets letters alphabet. manipulated study time (50, 100, 200, 500 ms per word) letter probabilistic structure to those originally used Letter-based familiarity responding was robust and present even at rates producing otherwise chance performance. A second experiment structural equation modelling led us interpret results...

The executive functions play an important role in storing and recovering autobiographical memories, especially episodic memories. These types of memories provide information about solutions experiences from the past that can be utilized as examples present when seeking to any problem. In addition, a close relationship between depression has been widely recognized. This study aims elaborate structural equations model empirically supports relationships among functions, memory, adaptive...

Background: Alzheimer’s disease (AD) stands as the prevailing type of dementia, marked by gradual memory loss and cognitive decline. Transcranial direct current stimulation (tDCS) is a non-invasive method used to regulate cortical brain function has been explored potential treatment for impairment. Objective: This study aimed compare effects daily home-based active or sham tDCS on in patients with early-stage AD its follow-up after one month. Methods: The involved randomized, blinded,...

This study aims to analyze implicit and explicit memory performance as a function of cognitive reserve (CR) in healthy control group (N = 39) mild impairment (MCI) 37). Both groups were subdivided into high low reserve, asked complete an associative recognition tasks. The results showed that the was able learn both tasks (η2 .19, p < .0001), CR fared better .06, .05). MCI sample, conversely, unable relationship, very little learning on association task. Participants diagnosed with plasticity...

The aim of the current study was to examine if recollection and familiarity decline in nondemented Parkinson's patients. To do so we compared a sample older people with disease (n = 32) control healthy on an associative recognition task which manipulated repetition pairs during phase (half were presented once half twice) obtain corrected estimates recollection, familiarity, false based logic process-dissociation procedure. results clearly show that is impaired but preserved memory for...

The aim of the current study is to examine effects stimuli repetition and age in false recognition using Deese–Roediger–McDermott experimental paradigm. Two matched samples 32 young adults healthy older studied 10 lists six words associated with three non-presented critical words. On half lists, were presented once, on other five times, always following a same sequential order. After each list, participants performed self-paced test containing 12 words: 6 non-studied (the 3 distractors)....

This study examines the relationship between cognitive reserve and familiarity processes in recognition memory. We hypothesize that people with high are able to better compensate alternative information retrieval processes. Forty-five participants, divided into low groups, conducted a experiment where they were asked discriminate studied non-studied words varied perceptual familiarity. The results indicated participants use improve their level of recognition. More importantly, used than...

We present an associative recognition experiment comparing three samples of healthy people (young people, older with high cognitive reserve [HCR], and low [LCR], each sample consisting 40 people), manipulating stimuli repetition during the study phase. The results show significant differences among in their overall performance. However, these are not due to a different use familiarity, but rather way using recollection: although there no hit rates between HRC LRC samples, LCR group makes...

Metodo: la tarea estudio las palabras estaban formadas por una mitad letras del alfabeto. En el test reconocimiento habia tres tipos nuevas no estudiadas: criticas mismas...
