Some recent studies have explored the false memory and its mechanisms. True memories depend on draw in the past, retrieve of the information, remember past events plus recombine (reorganize) them with new information to finally re-encode these elements creating a new memory. But, sometimes failures in this system lead to memory errors collaborating to false memory formation. This chapter will address new neuropsychological tools to evaluate true and false memory performance. Some neuropharmacological aspects as possible mechanisms of agonist and antagonist modulation of false memory will be discussed.

Substance abuse and susceptibility to false memory formation: a systematic review and meta-analysis

et al. 2023

View full text Add to dashboard Cite

BackgroundSubstance abuse has an impact on various cognitive domains, including memory. Even though this impact has been extensively examined across different subdomains, false memory has been sparsely studied. This systematic review and meta-analysis seek to synthesize the current scientific data concerning false memory formation in individuals with a history of substance abuse.MethodsPubMed, Scopus, the Cochrane Library, Web of Science, and PsycINFO were searched to identify all experimental and observational studies in English, Portuguese, and Spanish. Studies were then examined by four independent reviewers and, if they met the inclusion criteria, assessed for their quality. The Cochrane Risk of Bias Tool for randomized controlled trials (RCT) and the Joanna Briggs Institute (JBI) critical appraisal checklists for quasi-experimental and analytic cross-sectional studies were used to assess the risk of bias.ResultsFrom the 443 screened studies, 27 (and two more from other sources) were considered eligible for full-text review. A final 18 studies were included in the present review. Of these, 10 were conducted with alcoholics or heavy drinkers, four focused on ecstasy/polydrug users, three were done with cannabis users and one focused on methadone maintenance patients with current cocaine dependence. Regarding false memory type, 15 studies focused on false recognition/recall, and three on provoked confabulation.ConclusionsNone but one of the studies considering false recognition/recall of critical lures found any significant differences between individuals with a history of substance abuse and healthy controls. However, most of the studies taking into account false recognition/recall of related and unrelated events found that individuals with a history of substance abuse showed significantly higher rates of false memories than controls. Future research should continue to consider different types of false memories as well as their potential association with relevant clinical variables.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?RecordID=266503, identifier: CRD42021266503.

“…Fox et al, 2001; Kalechstein et al, 2007; Schilt et al, 2007; Zakzanis et al, 2007). Other aspects of memory function reportedly affected by ecstasy use include reduced initial encoding levels, impaired use of strategy during encoding, and poor performance on more complex learning and recall tasks (Brown et al, 2010; Gallagher et al, 2012; Montgomery et al, 2007, 2010; Quednow et al, 2006). These types of impairment support a developing theory that implicates frontostriatal network dysfunction in ecstasy-induced neurocognitive impairment (Bosch et al, 2013; Quednow et al, 2006).…”

Dysfunctional overnight memory consolidation in ecstasy users

et al. 2014

View full text Add to dashboard Cite

Sleep plays an important role in the consolidation and integration of memory in a process called overnight memory consolidation. Previous studies indicate that ecstasy users have marked and persistent neurocognitive and sleep-related impairments. We extend past research by examining overnight memory consolidation among regular ecstasy users (n=12) and drug naïve healthy controls (n=26). Memory recall of word pairs was evaluated before and after a period of sleep, with and without interference prior to testing. In addition, we assessed neurocognitive performances across tasks of learning, memory and executive functioning. Ecstasy users demonstrated impaired overnight memory consolidation, a finding that was more pronounced following associative interference. Additionally, ecstasy users demonstrated impairments on tasks recruiting frontostriatal and hippocampal neural circuitry, in the domains of proactive interference memory, long-term memory, encoding, working memory and complex planning. We suggest that ecstasy-associated dysfunction in fronto-temporal circuitry may underlie overnight consolidation memory impairments in regular ecstasy users.
