Objective: This study was designed to examine the effect of environmental enrichment during methamphetamine (METH) dependency and withdrawal on methamphetamine-induced spatial learning and memory deficits and obsessive-compulsive behavior. Method: Adult male Wistar rats (200 ± 10 g) chronically received bi-daily doses of METH (2 mg/kg, sc, with 12 hours intervals) for 14 days. Rats reared in standard (SE) or enriched environment (EE) during the development of dependence on METH and withdrawal. Then, they were tested for spatial learning and memory (the water maze), and obsessive-compulsive behavior as grooming behavior in METH-withdrawn rats...

The increasing abuse of the street drug crystal meth (methamphetamine) in many countries worldwide has resulted in a growing demand to treat patients who have acquired a methamphetamine-related disorder. The results of a systematic literature search which led to the consensus-based recommendations by the Working Group of the German Agency for Quality in Medicine (Ärztliches Zentrum für Qualität in der Medizin - ÄZQ) are presented. Pharmacological treatments were reviewed in 58 out of the 103 publications included...

Anxiety is often a core element of withdrawal symptoms; however, risk factors associated with anxiety symptoms during the early stage of withdrawal in methamphetamine (METH) users are not well understood. Two hundred ten METH-dependent subjects who had been abstinent for 1 to 7 days were recruited. We used a set of self-administrative questionnaires eliciting information on sociodemographics, detailed drug use history and anxiety. Beck Anxiety Inventory (BAI) was used to measure anxiety symptoms. METH users had a mean BAI score of 6...

RATIONALE: Both l- and d-methamphetamine (l- and d-MA) are more potent to release norpepinephrine (NE) than dopamine, and the selectivity is greater for l-MA than d-MA. Little is known of the in vivo pharmacology of l-MA. OBJECTIVE: This study compared the effects of l-MA and d-MA in assays of nociception, behavioral disruption, and impulsivity. METHODS: Antinociceptive effects of d- and l-MA were examined in two pain assays: the warm water tail withdrawal test for acute nociception and the von Frey test in complete Freund's adjuvant (CFA)-treated rats for chronic inflammatory pain...

Methamphetamine (METH) addicts lose control over drug consumption despite suffering multiple adverse medicolegal consequences. To mimic the negative events associated with drug addiction in humans, we recently introduced a rat model of self-administration (SA) with response-contingent punishment on METH intake. These procedures allowed us to distinguish between two addiction-like phenotypes in rats, those that sustained METH taking despite negative consequences (shock-resistant, SR) and rats that significantly reduced their METH intake (shock-sensitive, SS)...

Different methamphetamine use patterns in human subjects may contribute to inconsistent findings regarding the effects of methamphetamine abuse on brain and behavior. The present study investigated whether human-derived chronic and binge methamphetamine use patterns have differential effects on reward and neurochemistry in mice. Brain reward function in mice was evaluated during acute/prolonged withdrawal, and in response to methamphetamine challenge using the intracranial self-stimulation procedure. Brain dopaminergic, serotonergic and glutamatergic neurochemistry was determined with high-performance liquid chromatography...

BACKGROUND AND OBJECTIVE: Among substances that have a significant effect on sleep are stimulants, including amphetamines. As there are few studies assessing sleep quality in methamphetamine withdrawal this study aims to evaluate changes in sleep quality of methamphetamine dependent patients during early remission period by controlling depression and anxiety as confounding variables. METHODS: This study was conducted in Mashhad, Iran. Ninety amphetamine dependent patients, who were admitted in residential centers during 2012-2014 and met our inclusion criteria, were chosen by purposive nonprobability sampling method...

Background: Isolation-reared mice show social encounter-induced hyperactivity with activation of prefrontal serotonergic and dopaminergic systems, but it is not known whether this stress response is observed in other pathological conditions. Here we examined whether the social encounter stimulation induces abnormal behavior during withdrawal in chronic methamphetamine-treated mice. Methods: To induce methamphetamine-induced behavioral sensitization, male mice were injected with methamphetamine (1 mg/kg) once daily for 7 days...

BACKGROUND: The treatment of methamphetamine dependence is a continuing global health problem. Agonist type pharmacotherapies have been used successfully to treat opioid and nicotine dependence and are being studied for the treatment of methamphetamine dependence. One potential candidate is lisdexamfetamine, a pro-drug for dexamphetamine, which has a longer lasting therapeutic action with a lowered abuse potential. The purpose of this study is to determine the safety of lisdexamfetamine in this population at doses higher than those currently approved for attention deficit hyperactivity disorder or binge eating disorder...

BACKGROUND: The high prevalence and severity of methamphetamine (MA) abuse demands greater neurobiological understanding of its etiology. METHODS: We conducted immunoblotting and in vivo microdialysis procedures in MA high/low drinking mice, as well as in isogenic C57BL/6J mice that varied in their MA preference/taking, to examine the glutamate underpinnings of MA abuse vulnerability. Neuropharmacological and Homer2 knockdown approaches were also used in C57BL/6J mice to confirm the role for nucleus accumbens (NAC) glutamate/Homer2 expression in MA preference/aversion...

A high proportion of young methamphetamine (MA) users simultaneously consume alcohol. However, the potential neurological and behavioural alterations induced by such a drug combination have not been systematically examined. We studied in adolescent rats the long-term effects of alcohol, MA, and alcohol and MA combined on anxiety-like behaviour, memory, and neurogenesis in the adult hippocampus. Rats received saline, ethanol (ETOH, 1.5g/kg), MA (MA, 2mg/kg), or ethanol and MA combined (ETHOH-MA, 1.5g/kg ethanol plus 2mg/kg MA) via oral gavage, once daily for 5 consecutive days...

Binge/crash cycles of methamphetamine (MA) use are frequently reported by individuals suffering from MA use disorders. A MA binge is self-reported as multiple daily doses that commonly accumulate to 800 mg/day (~10 mg/kg/day for a 170 pound human). A genetic animal model with a similar vulnerability to binge-level MA intake is missing. We used selectively bred MA high drinking (MAHDR) and low drinking (MALDR) mouse lines to determine whether several procedural variations would result in binge-level MA intake...

Background: Synthetic drug use and abuse are on the rise. Governmental institutions report a shift in consumption from natural drugs to synthetic drugs, and show an increase in confiscation, particularly of methamphetamine and newly identified psychoactive substances. In addition, the media report an alarming increase in the rate of consumption and casualties resulting from the use of drugs such as "crystal meth" and warn against a flood of this and other designer drugs from eastern European countries. Objectives: The present article gives an overview of current popular and widely used synthetic drugs, both classical substances (amphetamine, methamphetamine, MDMA) and new psychoactive substances ("designer drugs", "legal highs")...

Rates of anxiety disorders among individuals who use methamphetamine are estimated to be as high as 30.2%. The presence of an anxiety disorder in methamphetamine users is associated with higher rates of relapse, non-adherence to treatment and poorer outcomes relative to methamphetamine users without an anxiety disorder. A review investigating current treatment options for methamphetamine dependence or withdrawal from methamphetamine was conducted using PubMed, CINAHL and PsycINFO. The focus of the review was trials that utilized an intervention and collected anxiety as an outcome measure...

BACKGROUND: Methamphetamine use is associated with a range of poor health, social and justice outcomes. In many parts of the world increased methamphetamine use has been identified as a major public health concern. Methamphetamine treatment programmes have been effective in reducing and ceasing use, however a range of barriers have prevented these programmes being widely adopted by methamphetamine users. This review examines the barriers to accessing meth/amphetamine treatment identified in the literature...

Ibogaine is a natural chemical compound, which belongs to the indole alkaloid family. It can be naturally found within the root bark of african plant Tabernanthe iboga. Ibogaine plays a significant role among tribal cultures. Ibogaine, in small amount, causes reduction of hunger, thirst and exhaustion. In bigger amount, however, it can cause intensive visions. Other effects include reduction or complete disappearance of absitnence symptoms visible in people addicted to the nicotine, alcohol, methamphetamine, cocaine or opioids, what has been scientifically proven after the tests on animals and small groups of people...

Psychotic disorders, such as schizophrenia, are characterized by prevalent and persistent executive deficits that are believed to be the result of dysfunctional inhibitory gamma-aminobutyric acid (GABA) processing of the prefrontal cortex (PFC). Methamphetamine (METH) is a commonly used psychostimulant that can induce psychotic and cognitive symptoms that are indistinguishable to schizophrenia, suggesting that METH-induced psychosis may have a similar GABAergic profile of the PFC. As the PFC consists of multiple subregions, the aim of the current study was to investigate changes to GABAergic mRNA expression in the prelimbic (PRL) and orbitofrontal (OFC) cortices of the PFC in rats sensitized to repeated METH administration...
