Kirk J. Mantione,Richard M. Kream,H. Kuzelova,Radek Ptacek,Jiri Raboch,Joshua M. Samuel,George B. Stefano +6 more
TL;DR: This review focuses on comparing the two most useful methods for whole transcriptome gene expression profiling in model organisms, and RNA-Seq clearly has a bright future in bioinformatic data collection.
Journal ArticleDOI

TL;DR: The principle published associations of DRD4 variants with psychiatric disorders are reviewed, finding associations were found with ADHD, substance dependences, several specific personality traits, and reaction to stress.
Journal ArticleDOI
Sleep disorders and daytime sleepiness in children with attention-deficit/hyperactivity disorder: a two-night polysomnographic study with a multiple sleep latency test.
TL;DR: After the inclusion of adaptation night and exclusion of psychiatric comorbidities, PSG showed no changes in basic sleep parameters or sleep timing, or in the frequency of sleep disorders (SDB, PLMS) in children with ADHD compared with controls, thus not supporting the hypothesis that specific changes in the sleep macrostructure and sleep disturbances are connected with ADHD.
Journal ArticleDOI

TL;DR: Disruptive patterns of eating behaviors, metabolically unfavorable nutritional status, and diminished physical activities of male children diagnosed with ADHD are linked to compromised growth and development and appearance of metabolic diseases in adulthood.
