Background Psychotropic drug use in Europe and the USA has increased in the past 20 years. The rise in mental health-care use instigated a debate about possible differences in prevalence rates between different ethnic groups in the Netherlands, although the exact differences were unknown. The aim of this study was to determine whether these minority groups were more or less likely than the native population to receive psychotropic drugs. Methods A descriptive population study was conducted using the Agis Health Database, containing demographic and health-care consumption data of approximately 1.5 million inhabitants of the Netherlands. Rates of prescriptions of psychotropic drugs from 2001 to 2006 and adjusted odds ratios for psychotropic drug prescriptions among native Dutch, Turkish and Moroccan ethnic groups were calculated. These data were analysed using logistic regression, after being adjusted for age, gender and socioeconomic status. Results The mean year prevalence of psychotropic drug prescriptions from 2001 to 2006 was 14.0%. Except for a decrease in anxiolytic drugs, the prescriptions of psychotropic drugs increased from 2001 to 2006. These trends were the same for all of the ethnic groups considered. Among both the Moroccan and Turkish populations, there was a higher risk of antidepressant and antipsychotic drug prescriptions, and a pronounced lower risk of ADHD medication and lithium prescriptions compared to the native population. Among the Turkish population, the risk of anxiolytic drug prescriptions was greater than in the native population. Conclusions Compared to the native population in the Netherlands, first-and second-generation Turkish and Moroccan immigrants had an increased risk of antidepressant and antipsychotic drug prescriptions and a decreased risk of ADHD medication and Lithium prescriptions. Further research is needed to clarify whether patients of different ethnic backgrounds with the same symptoms receive similar diagnosis and adequate treatment.

Schizophrenia is characterized by reality distortion, psychomotor poverty and cognitive disturbances. These characteristics contribute to a lesser social functioning and lower quality of life in patients with schizophrenia. It has been suggested that modafinil and its isomer armodafinil as an add-on strategy to antipsychotic treatment in patients with schizophrenia may improve cognitive functioning, attenuate fatigue, inactiveness and other negative functions as well as weight gain. In this paper we review the literature relevant to the question of whether modafinil and armodafinil are beneficial as add-on therapy in antipsychotic-treated patients with schizophrenia. A total of 15 articles were included in this review; of the 15 articles, 10 were randomized controlled trials (RCTs). Evidence for the use of modafinil or armodafinil as add-on therapy to antipsychotic drugs to alleviate fatigue, sleepiness and inactivity is inconclusive. One cohort study and one out of two single-dose crossover RCTs in which modafinil addition was studied could demonstrate a positive effect. All five RCTs of modafinil (three RCTs) and armodafinil (two RCTs) addition with a longer study duration could not demonstrate a positive effect. With respect to cognitive disturbances, animal models of cognitive deficits show clear improvements with modafinil. In RCTs with a treatment duration of 4 weeks or more, however, no positive effect could be demonstrated on cognitive functioning with modafinil and armodafinil addition. Yet, four single-dose crossover RCTs of modafinil addition show significant positive effects on executive functioning, verbal memory span, visual memory, working memory, spatial planning, slowing in latency, impulse control and recognition of faces expressing sadness and sadness misattribution in the context of disgust recognition. The addition of modafinil or armodafinil to an antipsychotic regime, despite theoretical and preclinical considerations, has not been proved to enhance cognitive function, attenuate fatigue, enhance activity, improve negative symptoms and reduce weight in patients with schizophrenia.

IntroductionDifferences in prevalence rates between different ethnic groups in the Netherlands and Belgium have been demonstrated. But there is no data on treatment differences among ethnic groups in the Netherlands.ObjectivesTo obtain more knowledge on differences in mental health care among ethnic groups in the Netherlands.AimsTo determine whether these minority groups will be more or less likely to be receiving psychotropic drugs.MethodsA descriptive population study was performed using the Agis Health Database, containing data of approximately 1.5 million inhabitants of The Netherlands. Rates of prescriptions of psychotropic drugs from 2001 to 2006 and adjusted odds ratios for psychotropic drug prescriptions among native Dutch, Turkish, and Moroccan ethnic groups were calculated. These data were analyzed using logistic regression, adjusted for age, gender and socioeconomic status.ResultsAmong both the Moroccan and Turkish populations there was a higher risk of antidepressant drug prescriptions, antipsychotic drug prescriptions and a pronounced lower risk of ADHD medication en lithium prescriptions compared with the native population. Among the Turkish population the risk of anxiolytic drug prescriptions compared with the native population was increased.ConclusionsCompared with the native population in the Netherlands, first and second generation Turkish and Moroccan immigrants had an increased risk of antidepressant and antipsychotic drug prescriptions and a decreased risk of ADHD medication and lithium prescriptions. Further research is needed to clarify if patients of different ethnic backgrounds with the same symptoms receive equal diagnosis and treatment.
