1. 16. Exploring the gut-brain axis in attention-deficit hyperactivity disorder

   Författare :Liu Yang; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : There is a bidirectional interaction between the gut and the brain, termed the gut-brain axis (GBA), involving e.g. the gut microbiota, and connecting the peripheral intestinal elements to the central nervous system (CNS). LÄS MER

3. 17. Oral health and behavior in children with attention deficit hyperactivity disorder

   Författare :My Blomqvist; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :ADHD ; adolescent; behavioral science ; child; cortisol; dental anxiety; dental caries; dentistry; health behavior; HPA axis;

   Sammanfattning : Attention deficit hyperactivity disorder (ADHD) is a common developmental disorder and has a substantial impact on many situations in the child s daily life. The present thesis investigates the behavior of children with ADHD in a dental setting that is, behavior management problems (BMP), interaction between child and dentist, dental anxiety, and stress and the oral health of these children compared to a control group.

4. 18. Attention-deficit/hyperactivity disorder : alterations of motor behaviour and dopaminergic transmission

   Författare :Aurelija Jucaite; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :AD HD; DCD; neurodevelopmental disorder; PET; dopamine transporter; dopamine D2 receptors; raclopride; striatum; midbrain; anticipatory postural adjustments;

   Sammanfattning : Altered catecholaminergic neurotransmission in the brain has long been thought to be of importance in the regulation of motor behavior and cognitive performance in children who had symptoms of distractability, impulsivity and clumsiness. The dopamine theory of AD/HD has mainly been substantiated by: i) the effects of psychostimulants, which target the dopamine transporter (DAT), and thereby reduce impulsiveness and inattentiveness, increase the striatal cerebral blood flow and functional activity, and ii) the evidence from linkage studies associating the AD/HD syndrome with allelic variations of genes encoding the dopamine transporter and, possibly, the dopamine D4 receptors.

5. 19. Attention deficit hyperactivity disorder in adults : neuropsychological deficits and functional impairments

   Författare :Ylva Holst; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The overall aim of the present thesis was to investigate the role of neuropsychological deficits in adult ADHD. Study I examined the psychometric properties of a new rating instrument, the Adult Executive Functioning Inventory (ADEXI), which focuses on deficits in working memory and inhibition. LÄS MER

7. 20. Attention-deficit/hyperactivity disorder and adverse health outcomes : from association to prevention

   Författare :Shihua Sun; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Attention-deficit/hyperactivity disorder (ADHD) is the most commonly diagnosed neurodevelopmental disorder, characterized by persistent inattention and/or hyperactivity-impulsivity that are inappropriate for one’s developmental stage. Individuals with ADHD suffer from adverse outcomes including somatic and psychiatric comorbidities. LÄS MER
