International ADHD in substance use disorders prevalence study.

Dr Van Hout has been invited by the ICASA network and IASP research team [Drs Geurt van de Glind; Trimbos Institute, The Netherlands; Dr Pieter-Jan Carpentier, ICASA; Josep Antoni Ramos-Quiroga, University of Barcelona, Spain, Professor Dr Frances Levin, University of Columbia, New York, USA and Professor Dr. Wim van den Brink, University of Amsterdam, The Netherlands] to undertake the research protocol for Ireland as part of this European study of the prevalence of ADHD in adult patients referred for treatment of addiction problems. The research team at Waterford Institute of Technology, School of Health Sciences will undertake this national study as part of the International Collaboration on ADHD and Substance Abuse [ICASA] â?~International ADHD in Substance Use Disorders Prevalence Studyâ?T [IASP study]. The International Collaboration on ADHD and Substance Abuse [ICASA] will provide Dr Van Hout and her team with full support from ICASA of the measurement instruments available and a central database at the University of Amsterdam, and will undergo training for procedures for data capture from Dr van de Glind, Trimbos Institute, The Netherlands. Eight European countries (Norway, Sweden, the Netherlands, Belgium, France, Spain, Switzerland and Hungary) USA and Australia have already participated in the first phase of the IASP study, which will close in September 2011. Over 2500 Substance Use Disorder [SUD] patients were sampled with approximately 38% scoring positive on the ADHD screener (ASRS). Of these 2500 patients over 1000 patients were evaluated on ADHD, Depression, Bipolar Disorder, Anti-Social Personality and Borderline Personality Disorder. A preliminary estimate of the prevalence of ADHD in SUD treatment seeking patients was recorded at 20 %. The second phase of study [IASP 2011] will commence in September 2011 for countries including Ireland, South Africa, Egypt and Brazil. Dr Van Hout has also been invited to partake in a systematic review paper on the risk factors for development of SUD in children/adolescents with ADHD in collaboration with the ICASA foundation.This resource was contributed by The National Documentation Centre on Drug Use.

Megapoles

Megapoles is a network of 15 European capital cities established in recognition that these cities face similar public health challenges. The aim of the network is to improve health and reduce health inequalities through information exchange, comparison and co-operation between capital cities. Since its establishment in 1997 Megapoles has produced a number of publications that focus on the distinctive features of health promotion in an urban context. The Megapoles member cities are: Amsterdam, Athens, Berlin, Brussels, Copenhagen, Dublin, Helsinki, Lazio-Roma, Lisbon, London, Lyon, Madrid, Oslo, Stockholm and Vienna. Although not a capital city Lyon is a participant in the Megapoles network. Member cities are represented on the Megapoles network by senior politicians and health executives.

Although it has long been known that genetic factors play a major role in shaping the electroencephalogram (EEG), progress on identifying the underlying genes has, until recently, been limited. Using quantitative trait loci (QTL) analyses several genomic loci affecting the sleep EEG could be mapped in the mouse. For three of these QTLs the responsible genes were identified leading to the implication of novel signaling pathways affecting EEG traits. Moreover, the insight that in the mouse the sleep-wake dependent dynamics in the expression of EEG slow waves during sleep is under strong genetic control has paved the way for candidate gene studies in humans investigating the contribution of specific polymorphism to the trait-like inter-individual differences in the susceptibility to sleep loss. Candidate gene studies in the mouse were also instrumental in establishing an alternative, noncircadian function for clock genes in the homeostatic regulation of sleep and modulating rhythmic EEG activity of thalamocortical origin. Future efforts should combine system genetics approaches in the mouse and genome-wide association studies in humans to facilitate uncovering the molecular pathways that shape brain activity.
