Newest firstIntroduction Cannabis use during adolescence and young adulthood has been associated with neurocognitive alterations. However, limited attention has been paid to whether these findings vary according to developmental stage and regional context. This systematic review examined the neurocognitive effects of cannabis use in adolescents and young adults, with particular attention to age-related patterns and geographic…
Open article record in new tab ↗Rationale Widespread legalization of cannabis in the US in recent years has coincided with increasing use of alcohol and cannabis at the same time. Cannabis is thought to confer synergistic effects on alcohol intoxication, and the potential for increased cognitive impairment is a concern. Most prior co-administration studies have relied on low-THC cannabis, limiting generalizability to real-world consumption of hi…
Open article record in new tab ↗Polysialic acid (PSA), a highly negatively charged glycan attached mainly to the neural cell adhesion molecule (NCAM), is emerging as a critical but underrecognized extracellular regulator of glutamatergic neurotransmission. While previous literature has focused on PSA's developmental roles, increasing evidence indicates that PSA-NCAM also contributes to synaptic plasticity mechanisms in the mature brain. This rev…
Open article record in new tab ↗According to the most recent data published by the World Health Organization (WHO), it is estimated that approximately 332 million persons worldwide suffer from depression. The relationship between depression and alcohol consumption is complex and bidirectional. This study aimed to investigate the effects of cannabidiol (CBD) on behavior and malondialdehyde (MDA) imbalance in female Wistar rats exposed to chronic…
Open article record in new tab ↗Prospective memory (PM) deficits are common among people with HIV (PWH) and are linked to poor clinical outcomes. Risk factors for PM deficits in PWH are poorly understood. While cannabis use is associated with worse PM in people without HIV, it is unclear whether this association generalizes to PWH. Three hundred and seven PWH (79% with regular cannabis use) completed the Memory for Intentions Test (MIST). Associ…
Open article record in new tab ↗Maple Syrup Urine Disease (MSUD) is caused by a genetic mutation in the branched-chain α-ketoacid dehydrogenase complex, resulting to accumulation of branched-chain amino acids (BCAAs) that affect the central nervous system and cause neurochemical alterations and behavioral changes. In this line, full-spectrum cannabidiol (CBD)-rich oil has emerged as a potential therapeutic strategy. Therefore, this study aims to…
Background Navigation and memory are hippocampal functions that are essential for survival. One of the key modulators of hippocampal activity is the endocannabinoid system through the cannabinoid receptor type 1 (CB1). CB1 is widely expressed in various types of hippocampal cells. While it is known that CB1 participates in memory processes, its specific roles in different cell types and differences between sexes r…
The expanding legalization of cannabis raises significant public health concerns about its use during pregnancy, particularly due to the limited understanding of its impact on neurodevelopment. Existing research suggests that perinatal cannabis or cannabinoid exposure may impair learning and memory; however, variations in study design hinder the ability to draw generalizable conclusions. Clinical studies are limit…
Open article record in new tab ↗(-)-Cannabidiol (CBD) is a nonpsychotropic phytocannabinoid found in Cannabis strains with well-established pharmacological applications. Conversely, (+)-cannabidiol (ent-CBD), the non-natural enantiomer of CBD, has been involved in a limited number of pharmacological studies. Therefore, CBD and ent-CBD are synthesized using (R)-(-)- and (S)-(+)-carvone as starting materials, respectively, via a highly diastereose…
Addiction is increasingly recognized as a disorder involving not only reward dysregulation but also alterations in core cognitive processes, including learning and memory. Although various studies have documented memory impairments in substance use and behavioral addictions, evidence remains inconsistent-particularly regarding verbal memory deficits and the diagnostic relevance of specific recall error types. This…
Adolescent binge drinking has lasting behavioral consequences by disrupting the endocannabinoid system (ECS) and depleting brain omega-3. The natural accumulation of omega-3 fatty acids in cell membranes is crucial for maintaining the membrane structure, supporting interactions with the ECS, and restoring synaptic plasticity and cognition impaired by prenatal ethanol (EtOH) exposure. However, it remains unclear wh…
Deficits in learning and memory are some of the most commonly reported symptoms following a traumatic brain injury (TBI). We will examine whether the neural basis of these deficits stems from alterations to bidirectional synaptic plasticity within the hippocampus. Although the CA1 subregion of the hippocampus has been a focus of TBI research, the dentate gyrus should also be given attention as it exhibits a unique…
Adolescents and young adults are using synthetic cannabinoids at increasing rates, and the use of synthetic cannabinoids (SCs) carries significant medical and psychiatric risks. Although studies have been conducted to preliminarily explore the pharmacological effects of the fourth-generation synthetic cannabinoid 5F-EDMB-PICA (ethyl 2-(1-(5-fluoropentyl)-1 H-indole-3-carboxamido)-3,3-dimethylbutyrate), there is st…
The increasing use of Synthetic cannabinoids (SCs) in adolescents and young adults poses significant medical and psychiatric risks, and previous reports have been dominated by single-age animal studies. Here, we first investigated the effects of a single exposure of the fourth-generation synthetic cannabinoid 4F-ABUTINACA on cognitive behaviors in adolescent (PND 28-35 days) and adult (PND 49-56 days) male mice in…
Open article record in new tab ↗Cannabidiol (CBD) has gained a lot of interest in recent years for its purported medicinal properties. CBD has been investigated for the treatment of anxiety, depression, epilepsy, neuroinflammation, and pain. Recently there has been an interest in CBD as a possible treatment for age-related disorders such as Alzheimer's disease and related disorders (ADRD). Here we tested the hypothesis that chronic CBD administr…
ImportanceTerminally ill patients sometimes inquire about preservation procedures (e.g. cryopreservation, aldehyde-based fixation) as end-of-life treatment options, yet physician perspectives on feasibility and ethical acceptability remain uncharacterized. ObjectiveTo assess US physicians estimates of preservation feasibility, views on interventions to improve outcomes, and positions on ethical and legal framework…
Open article record in new tab ↗Background Palmitoylethanolamide (PEA) is an endocannabinoid-like lipid mediator which is naturally produced in the body and found in certain foods. The aim of this study was to assess the effect of a bioavailable formulated form of PEA (Levagen+®) on serum BDNF levels and parameters of cognitive function in healthy adults. Methods A randomised double-blinded placebo-controlled cross-over trial was implemented to…
Open article record in new tab ↗Acquisition and extinction of associative fear memories are critical for guiding adaptive behavioral responses to environmental threats, and dysregulation of these processes is thought to represent important neurobehavioral substrates of trauma and stress-related disorders including posttraumatic stress disorder (PTSD). Endogenous cannabinoid (eCB) signaling has been heavily implicated in the extinction of aversiv…
Open article record in new tab ↗The basolateral amygdala plays pivotal roles in the regulation of fear and anxiety and these processes are profoundly modulated by different neuromodulatory systems that are recruited during emotional arousal. Recent studies suggest activities of BLA interneurons and inhibitory synaptic transmission in BLA principal cells are regulated by neuromodulators to influence the output and oscillatory network states of th…
