We report the case of a 31-year-old woman, admitted to the hospital for chest pain, dying a few days later from septic multiorgan failure, and showing at autopsy foci of acute demyelination in the occipital lobe. Gas chromatography/mass spectrometry analysis revealed the presence of amphetamine in the demyelinated area, which might be considered as the pathogenic agent, since other causes for d...

AIM Amphetamine and its derivates can induce, usually after many intoxications, schizophrenia-like psychosis. These disorders appeared only in part patients with amphetamine dependence. Aim of the study was to establish prevalence of selective risk factors of schizophrenia development in amphetamine users: 1) with amphetamine-induced schizophrenia-like psychosis, 2) with schizophrenia, and 2) w...

Amphetamine abuse may lead to a psychotic state, its symptomatology being very similar to what is seen in paranoid schizophrenia. Failure of attentional inhibition of irrelevant information is thought to be associated with the psychotic symptoms in schizophrenia. Negative priming (NP) paradigm is believed to measure this impairment. Several studies have shown impaired NP in schizophrenia. In th...

  There is evidence indicating that adrenoceptor mechanisms may influence some of the behaviors in rat. However the role of adrenoceptor agents on sniffing has not been identified. In the present study, the influence of adrenoceptor agents on sniffing induced by apomorphine and amphetamine has been investigated. Male Albino rats, weighing 150-250 g were used for all experiments. The behavior wa...

Monamines subserve many critical roles in the brain, and monoaminergic drugs such as amphetamine have a long history in the treatment of neuropsychiatric disorders and also as a substance of abuse. The clinical effects of amphetamine are quite variable, from positive effects on mood and cognition in some individuals, to negative responses in others, perhaps related to individual variations in m...

This study aimed to replicate a previous study which showed that endogenous opioid release, following an oral dose of amphetamine, can be detected in the living human brain using [11C]carfentanil positron emission tomography (PET) imaging. Nine healthy volunteers underwent two [11C]carfentanil PET scans, one before and one 3 h following oral amphetamine administration (0.5 mg/kg). Regional chan...
