amnesia/cannabis

The present study intended to investigate the involvement of dopaminergic and glutamatergic systems of the basolateral amygdala in amnesia induced by the stimulation of dorsal hippocampal cannabinoid receptors in male Wistar rats. The animals were stereotaxically implanted with guide cannulas in the

We report an unusual case of sudden isolated transient amnesia triggered by acute marijuana use. The memory disorder, apart from the long duration, had the characteristics of a transient global amnesia-like episode. Acute marijuana intoxication can affect memory more globally and severely than

A 6-year-old boy accidentally became intoxicated with marijuana secondary to ingesting cookies laced with marijuana. He presented with retentive memory deficit of sudden onset that was later diagnosed as transient global amnesia. Transient global amnesia as a result of marijuana intoxication is an

The aim of the current study was to investigate the involvement of GABA neurotransmission in the CA1 region and endocannabinoid system in the basolateral amygdala (BLA) on morphine-induced memory impairment. We hypothesized that possible functional interaction between the GABAergic and cannabinoid

The ventral hippocampus (VH) has a high distribution of cannabinoid CB1 receptors which are important in modulating stress responses. Stress exposure activates the hypothalamic-pituitary-adrenal axis (HPA) which can impact hippocampal formation to change hippocampus-based memories. The purpose of

Administration of drugs activating cannabinoid CB(1) receptors in the brain induces memory deficit in rodents, and blockade of these receptors may restore memory capacity in these animals. Central administration of beta-amyloid or beta-amyloid fragments may also lead to memory disturbances. This

Alcohol-related blackouts (ARBs) are anterograde amnesias related to heavy alcohol intake seen in about 50% of drinkers. Although a major determinant of ARBs relates to blood alcohol concentrations, additional contributions come from genetic vulnerabilities and possible impacts of cannabis use

BACKGROUND Synthetic cannabinoids are getting more popular among young people and illicit manufacturers. We report a case series of occupational transdermal poisoning with synthetic cannabinoids. METHODS Three customs inspectors got in contact with a sticky substance with their fingertips because

When admitted in an emergency unit, young patients often present acute neurological effects of smoked marijuana. Other chronic adverse effects of marijuana are probably underestimated: postural syncope, arteritis, chronic bronchitis, amnesia. Marijuana may trigger a myocardial infarction and have a

The present study investigated the possible involvement of the central amygdala (CeA) cannabinoid receptors type-1 (CB1Rs) in the interactive effects of morphine and nicotine on memory formation in a passive avoidance learning task. Our results showed that systemic administration of morphine (3 and

OBJECTIVE To investigate the effects of extract from Fructus cannabis (EFC) that can activate calcineurin on learning and memory impairment induced by chemical drugs in mice. METHODS Bovine brain calcineurin and calmodulin were isolated from frozen tissues. The activity of calcineurin was assayed

Ethanol and morphine are largely co-abused and affect memory formation. The present study intended to investigate the involvement of cannabinoid CB1 receptors of the basolateral amygdala (BLA) in cross state-dependent memory retrieval between morphine and ethanol. Adult male Wistar rats received

Functional interactions between cannabinoid and alpha-2 adrenergic systems in cognitive control in the medial prefrontal cortex (mPFC) seem possible. The present study evaluated the possible role of alpha-2 adrenoceptors of the prefrontal cortex on effect of arachidonylcyclopropylamide (ACPA), a

In the present study, we investigated the influence of bilateral intra-central amygdala (intra-CeA) microinjections of N-methyl-D-aspartate (NMDA) receptor agents on amnesia induced by a cannabinoid CB1 receptor agonist, arachydonilcyclopropylamide (ACPA). This study used a step-through inhibitory
