BACKGROUND Brain dopamine neurons code rewarding environmental stimuli by releasing endogenous dopamine, a transmission signal that is important for reinforcement learning. Human reward-seeking gambling behavior, and especially pathological gambling, has been presumed to be modulated by brain dopamine. METHODS Striatal dopamine release was studied with(More)
BACKGROUND Both methadone- and buprenorphine-treated opioid-dependent patients frequently show cognitive deficits in attention, working memory, and verbal memory.

The subjects were(More)
The aim of this study was to determine predictors of the response to escitalopram, a selective serotonin re-uptake inhibitor antidepressant and memantine, a non-competitive glutamate NMDA receptor blocker, for the treatment of major depression comorbid with alcohol dependence. Eighty alcohol dependent treatment-seeking adult patients with comorbid major(More)
BACKGROUND Opioid-substitution treatment (OST) for opioid dependence (OD) has proven effective in retaining patients in treatment and reducing illegal opiate abuse and crime. Consequently, the World Health Organization (WHO) has listed the opioid agonists methadone and buprenorphine as essential drugs for OD that should be available worldwide. In many areas(More)

However, studies examining general attitudes towards gambling at the population level are scarce. The first aim of this study was to investigate general attitudes of the Finnish population towards gambling. The second aim was to(More)
