Description succincte
(Anglais)
|
Attention-deficit hyperactivity disorder (ADHD) is a common and clinically heterogeneous disorder that is associated with considerable social costs. It is estimated that up to more than one half of ADHD children continue to manifest symptoms in adulthood. Over the past decades, electrophysiological research has produced a great amount of qEEG and ERP information about children and adolescents with ADHD. In recent years, several studies have identified subgroups of ADHD children with distinct EEG profiles, suggesting that children with a diagnosis of ADHD may constitute a heterogeneous group with different underlying electrophysiological abnormalities. The planned study is aimed to investigate the presence of EEG and ERP clusters within a sample of adults with attention-deficit hyperactivity disorder. The identification of distinct EEG-defined subgroups of adults with ADHD would have considerable implications for the use of EEG in the assessment and diagnosis of ADHD. The EEG will be recorded in a resting condition, as well as while performing continuous performance tasks. Clinical subjects will be grouped by means of cluster analysis.

Attention-deficit hyperactivity disorder (ADHD) is a common and clinically heterogeneous disorder that is associated with considerable social costs. It is estimated that up to more than one half of ADHD children continue to manifest symptoms in adulthood. Over the past decades, electrophysiological research has produced a great amount of qEEG and ERP information about children and adolescents with ADHD. In recent years, several studies have identified subgroups of ADHD children with distinct EEG profiles, suggesting that children with a diagnosis of ADHD may constitute a heterogeneous group with different underlying electrophysiological abnormalities. The study is aimed to investigate the presence of EEG and ERP clusters within a sample of adults with attention-deficit hyperactivity disorder. The identification of distinct EEG-defined subgroups of adults with ADHD would have considerable implications for the use of EEG in the assessment and diagnosis of ADHD. The EEG will be recorded in a resting condition, as well as while performing continuous performance tasks. Clinical subjects will be grouped by means of cluster analysis. Besides the neurophysiological assessment, subjects pass a series of neuropsychological tasks. Status quo June 2007: The European network is set up. The following countries participate in the study: Norway, Poland, Germany, Austria, Italy, Macedonia, Turkey, Switzerland, USA). Preparatory work (definition of interview, questionnaires, neuropsychological testing tools, EEG testing tools) is completed. Data collection has started in January 2007 and is in progres.
