Although the importance of individual characteristics and psychological factors has been conceptualized in many models of information seeking behaviour (e.g., Case 2007; Wilson 1999) research into personality issues has only recently attracted attention in information science. This may be explained by the work by Heinström (2002; 2003; 2006a; 2006b; 2006c), but may also be explained by the emer...
Drug dependence is a far-reaching problem that goes beyond the individual to society at large. While a myriad of substances have addictive properties, the scope of this review is limited to crack cocaine – how the brain, specifically the mesolimbic dopamine system, is compromised by administration of crack cocaine, physiological changes and the relevance of dopamine levels to susceptibility to ...
Drugs that increase GABA levels in the brain reduce cocaine seeking in rodents and humans, suggesting that GABAergic inhibition regulates cocaine-seeking behavior. We previously reported that repeated cocaine exposure in vivo facilitates long-term potentiation by reducing the strength of GABAergic inhibition in dopamine neurons of the ventral tegmental area (VTA). Selective blockade of cocaine-...
We aimed to compare adult patients with attention deficit hyperactivity disorder (ADHD) and matched controls on four dimensions of impulsivity (urgency, lack of premeditation, lack of perseverance, and sensation seeking) and to examine the association between impulsivity and ADHD symptoms. The study was conducted on 219 participants: 72 adult ADHD patients and 147 aged and gender matched contro...
Drug addiction is associated with long-lasting neuronal adaptations including alterations in dopamine and glutamate receptors in the brain reward system. Treatment strategies for cocaine addiction and especially the prevention of craving and relapse are limited, and their effectiveness is still questionable. We hypothesized that repeated stimulation of the brain reward system can induce localiz...
Drug abuse is a public health issue, particularly among adolescents and young adults. Therefore, the purpose of our study to determine prevalence rate drugs use identify certain factors that can serve as predictors drug use. A total 431 students from Mohammed V University in Rabat participated this descriptive cross-sectional survey. The (regular users experimenters) was 32.9%. Cannabis has fre...
Background: The food addiction (FA) model is receiving increasing interest from the scientific community. Available empirical evidence suggests that this condition may play an important role in the development and course of physical and mental health conditions such as obesity, eating disorders, and other addictive behaviors. However, no epidemiological data exist on the comorbidity of FA and g...
