Patients with ADHD tend to have smaller amygdala volumes. ADHD patients presented less activation in the area of the left frontal pole than the controls. There was no amygdala activation stated when presenting the pleasant images. Whereas bigger activation of the left amygdala was found in patients while presenting them unpleasant images. These results might suggest that lower emotional processing and less control of impulsivity is associated with dysfunctional amygdala in ADHD patients.

Background: Schizophrenia is a disabling mental disorder with high prevalence and that usually  requires long-term follow-up and expensive lifelong treatment. The cost of schizophrenia treatment consumes a significant amount of the health services' budget in western countries. Objective: The aim of the study was to find out about the costs related to schizophrenia across different european countries and compare them. Results: Schizophrenia treatment costs an estimated 18 billion euros annually worldwide. The direct costs associated with medical help are only part of the total expenditure. The indirect costs are an equally (or even more)important part of the total cost. These expenses are related to the lack of productivity of schizophrenic patients and the cost that relatives have to bear as a result of taking care of their affected relatives. Conclusions: Although data on the cost of schizophrenia may vary slightly between different european countries, the general conclusion that can be drawn is that schizophrenia is a very costly disorder. Not only because of direct costs related to medical procedures, but also due to the non-medical (indirect) costs. Together this suggests the need to investigate cost-efficient strategies that could provide a better outcome for schizophrenic patients, as well as the people who care for them.

Discuss this article AbstractWe report the case of a 10 year old patient diagnosed with attention deficit hyperactivity disorder (ADHD) and comorbid video game addiction, who was treated with medication combined with a novel cognitive training method based on video games called TCT method. A great risk of developing video game or internet addiction has been reported in children, especially in children with ADHD. Despite this risk, we hypothesize that the good use of these new technologies might be useful to develop new methods of cognitive training. The cognitive areas in which a greater improvement was observed through the use of video games were visuospatial working memory and fine motor skills. TCT method is a cognitive training method that enhances cognitive skills such as attention, working memory, processing speed, calculation ability, reasoning, and visuomotor coordination. The purpose of reviewing this case is to highlight that regular cognitive computerized training in ADHD patients may improve some of their cognitive symptoms and might be helpful for treating video game addiction.

Smaller amygdala volumes have been observed in patients with ADHD. Our results suggest that greater emotional processing and less control of impulsivity are associated with smaller amygdala volumes in ADHD patients. Furthermore, the right amygdala would play a bigger role in impulsivity and behaviour control than the left amygdala. Further studies involving larger samples of adult patients with ADHD and using multimodal designs are needed.

Background:The purpose of this multicenter Spanish study was to evaluate the response to immediate-release methylphenidate by children and adults diagnosed with attention-deficit/hyperactivity disorder (ADHD), as well as to obtain information on current therapy patterns and safety characteristics.Methods:This multicenter, observational, retrospective, noninterventional study included 730 patients aged 4–65 years with a diagnosis of ADHD. Information was obtained based on a review of medical records for the years 2002–2006 in sequential order.Results:The ADHD predominantly inattentive subtype affected 29.7% of patients, ADHD predominantly hyperactive-impulsive was found in 5.2%, and the combined subtype in 65.1%. Overall, a significant lower Clinical Global Impression (CGI) score and mean number of DSM-IV TR (Diagnostic and Statistical Manual of Mental Disorders Fourth Edition, Text Revision) symptoms by subtype were found after one year of treatment with immediate-release methylphenidate; CGI decreased from 4.51 to 1.69, symptoms of inattention from 7.90 to 4.34, symptoms of hyperactivity from 6.73 to 3.39, and combined subtype symptoms from 14.62 to 7.7. Satisfaction with immediate-release methylphenidate after one year was evaluated as “very satisfied” or “satisfied” by 86.90% of the sample; 25.75% of all patients reported at least one adverse effect. At the end of the study, 41.47% of all the patients treated with immediate-release methylphenidate were still receiving it, with a mean time of 3.80 years on therapy.Conclusion:Good efficacy and safety results were found for immediate-release methylphenidate in patients with ADHD.
