NCT00977353
Major depressive disorder is a complex disease and most currently available antidepressants aiming at monoamine neurotransmission exhibit limited efficacy and cognitive effects. N-methyl-D-aspartate (NMDA), one subtype of glutamate receptors, plays an important role in learning and memory. N-methyl-D-aspartic acid (NMDA) enhancing agents, such as sarcosine (N-methylglycine), have been used as adjunctive therapy of schizophrenia. Sarcosine improved not only psychotic but also depressive symptoms in patients with schizophrenia. To confirm its antidepressant effect, the purpose of this study is to compare citalopram and sarcosine in efficacy for major depressive patients.
NCT00344474
Personality targeted cognitive behavioural interventions have been shown to be effective in reducing alcohol and drug misuse in adult substance abusers (Conrod et al., 2000) and adolescent drinkers (Conrod et al, in press). As these interventions target personality traits linked to risk for addictive and non-addictive mental disorders, the aim of this study is to examine the extent to which this approach can prevent and/or reduce alcohol and drug misuse as well as have an impact on the onset or severity of emotional and behavioural problems in young people.
