Potential Adverse Effects of Amphetamine Treatment on Brain and Behavior: A Review

Effects of prolonged stimulant treatment in adults, however, have not been fully explored, and this is a current research priority 1. While the enlargement in parietal volume and the deficit in hippocampal volume were also associated with cognitive deficits in the above-cited studies, one report of basal ganglia volume being greater than in a comparison group found the volumetric measure to be positively correlated with verbal fluency and fine motor performance, but negatively associated with duration of methamphetamine use Annual Review of Pharmacology and Toxicology.

The vesicular monoamine transporter is not regulated by dopaminergic drug treatments.

Amphetamine sensitization alters dendritic morphology in prefrontal cortical pyramidal neurons in the non-human primate. Jjrnal the presence of fluoride, enamel demineralization starts at a lower pH. Effects of neonatal and prepubertal hormonal manipulations upon estrogen neuroprotection of the nigrostriatal dopaminergic system within female and male mice. Nine- or fewer repeat alleles in VNTR polymorphism of the dopamine transporter gene is a strong risk factor for prolonged methamphetamine psychosis.

Case Reports in Psychiatry

Frantz K, Van Hartesveldt C. In contrast, administration of high stimulant doses to rodents or nonhuman primates promotes a profound decrement in VMAT 2 as well as in the other markers for dopaminergic nerve terminals – The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition DSM-IV recognizes diagnoses of amphetamine-induced psychotic disorder with delusions and amphetamine-induced psychotic disorder with hallucinations.


The behavior of children receiving benzedrine. As a side note, jurbal abuse has occasionally been clinically linked to choreoathetoid-type involuntary movement disorders, and neuroleptics are thought to effectively treat these disorders by normalizing an excessive ratio of dopamine to acetylcholine in the corpus striatum but for another possible mechanism see Some of the evidence derived from these studies in rats suggests a transition in susceptibility to methamphetamine-induced neurotoxicity occurring around PND Metabolite alterations in basal ganglia associated with methamphetamine-related psychiatric symptoms: Other significant medical history includes asthma and capsular contraction after recent breast augmentation.

Growth on stimulant medication; clarifying the confusion: For clinical safety, it is perhaps even more essential to identify individual risk factors for adverse effects of amphetamines.

Adolescent development alters stressor-induced Fos immunoreactivity in rat brain. Nevertheless, it is potentially important that treatment within approved dose ranges with amphetamines, especially newer extended-release formulations, have produced residual low, but detectable, steady-state blood levels up to 24 h after administration.

Cognitive, genetic, and other biological markers associated with risk for adverse events from stimulant exposure should be explored. Decision making, the P3, and the locus coeruleus-norepinephrine system. jurna

Exposure of adolescent rats to oral methylphenidate: Assessments of central toxicity and adverse psychological effects during late adulthood and senescence of adults who receive prolonged courses of amphetamine treatment are warranted. Toxicology and Applied Pharmacology. Cerebral metabolic dysfunction and impaired vigilance in recently abstinent methamphetamine abusers.

Imaging the dopamine transporter: High doses of amphetamines have produced enlarged chromatolytic medulla neurons in cats 43and parenteral dosing in rodents can also produce swollen or reduced dopaminergic axons, and serotonin deficits.

Research agencies should study effects of protracted exposure in nonhuman primates, and sponsor longitudinal studies of indices of healthy aging in adults exposed to protracted courses of medical amphetamines.


A comparison of patterns of methamphetamine and cocaine use. To receive news and publication updates for Case Reports in Psychiatry, enter your email address in the box below.

Advances in Biochemical Psychopharmacology. Ten Cate and P. Amphetamine was initially synthesized in Berlin in as 1-methylphenethylamine. Concerns have been voiced that, in addition to neurobiological adaptations, prolonged exposure to amphetamine could damage components of the central nervous system. View at Google Scholar G. Therefore, the quality of methamphetamine and impurities found on the street product at street level should vary a lot with possible side effects which are unknown.

Potential Adverse Effects of Amphetamine Treatment on Brain and Behavior: A Review

American Journal of Psychiatry. Reinforcing, subject-rated, performance and physiological effects of methylphenidate and d-amphetamine in stimulant abusing humans. However, as methylphenidate was approved for government subsidies in lateits use has probably since increased They noted recovery in thalamic but not striatal deficits in relative glucose metabolism. At low doses, levoamphetamine produces greater arousal than dextroamphetamine, acting primarily on norepinephrine.

Though the paradigm used by Ricaurte et al. It is remarkable that the prevalence of problematic use of amphetamine has been amfwtamin in the elderly, and that prescription substance abuse in this population may augment associated risks and require unique considerations for diagnosis and treatment Some children were unaffected, while others showed strong growth suppression.
