Methamphetamine (MA) dependence is associated with deficits in episodic verbal memory, but the cognitive mechanisms underlying such impairments are not known. The authors evaluated a component process model of episodic verbal memory in 87 persons with MA dependence (MA+) and 71 demographically similar non-MA-using controls (MA-). Compared with MA- controls, MA+ participants demonstrated deficie...

BACKGROUND Individuals with substance-use disorders exhibit emotional problems, including deficits in emotion recognition and processing, and this class of disorders also has been linked to deficits in dopaminergic markers in the brain. Because associations between these phenomena have not been explored, we compared a group of recently abstinent methamphetamine-dependent individuals (n=23) with...

There is a growing evidence that serotoninergic systems modulate dopaminergic neurotransmission. We analyzed the association between the variations in the brain tryptophan hydroxylase 2 (TPH2) gene, a rate limiting enzyme for serotonin biosynthesis, and methamphetamine (METH) dependence/psychosis in a Japanese population. We found ten single nucleotide polymorphisms (SNPs) and two polynucleotid...

The abuse of stimulants such as cocaine, amphetamine, and methamphetamine is a huge problem in many parts of the world. Abuse of these drugs does not ruin just the user's life, but also adversely affects those around them. Despite many years of research, there are no approved medications for stimulant dependence, and treatment is focused on psychotherapy and abstinence. Over the last 10 to 20 y...

Methamphetamine use among adolescents is a significant social and public health concern. Despite increased awareness of methamphetamine use among younger people, relatively little research has examined the effects of adolescent methamphetamine use compared to adult use. Thus, much remains to be learned about how methamphetamine alters adolescent brain function and behavior. In this article we r...

Genetic studies on METH abuse and METH psychosis are influential in the fields of comorbidity of substance abuse, etiological models of schizophrenia, and the nosology of prolonged or chronic substance-induced psychosis. Most data of genetic markers associated with METH abuse or METH psychosis derived from Asian samples. Previous studies on Meth abuse and Meth psychosis have identified many pot...

BACKGROUND Methamphetamine is a major drug of abuse with no effective pharmacotherapy available. Trace amine associated receptor 1 is implicated in cocaine addiction and represents a potential therapeutic target. However, the effects of trace amine associated receptor 1 agonists on addiction-related behavioral effects of methamphetamine are unknown. METHODS This study examined the effects of ...

The current bulletin assesses whether there is any relationship between the increasing assault rate in NSW seen over the past decade and increasing methamphetamine use. During this time, there have been several changes to methamphetamine use patterns that could have contributed to an increase in methamphetaminerelated problems, such as violent behaviour. There is currently insufficient evidence...

Cytochrome P450 3A4 (CYP3A4) is the major drug metabolic enzyme, and is involved in the metabolism of antiretroviral drugs, especially protease inhibitors (PIs). This study was undertaken to examine the effect of methamphetamine on the binding and metabolism of PIs with CYP3A4. We showed that methamphetamine exhibits a type I spectral change upon binding to CYP3A4 with δAmax and KD of 0.016±0.0...
