  2. 1. The bladder and the brain : Studies on the pathogenesis and the treatment of nocturnal enuresis

    Author : Tryggve Nevéus; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrics and gynaecology; nocturnal enuresis; children; desmopressin; osmoregulation; sleep; arousal; detrusor instability; incontinence; oxybutynin; Obstetrik och kvinnosjukdomar; Obstetrics and women s diseases; Obstetrik och kvinnosjukdomar; pediatrik; Pediatrics;

    Abstract : Opinions differ as to whether nocturnal enuresis is caused by high arousal thresholds, nocturnal polyuria or nocturnal bladder instability. In spite of the currently available therapeutic options - the antidiuretic drug desmopressin and alarm treatment - approximately 25% of children suffering from enuresis cannot be successfully treated.

  4. 2. Noise improves cognitive performance in children with dysfunctional neurotransmission

    Author : Göran Söderlund; Sverker Sikström; Lars-Göran Nilsson; Edmund Sonuga-Barke; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ADHD; noise; stochastic resonance; dopamine; episodic memory; model; brain arousal; SPT; cognitive performance; children; Psychology; Psykologi; psykologi; Psychology;

    Abstract : Research on children with Attention Deficit Hyperactivity Disorder (ADHD) has shown that they are extremely sensitive to distraction from external stimuli that lead to poor cognitive performance. This thesis shows that cognitive performance can be improved if this external stimulus is smooth and continuous (e.g. auditory white noise). READ MORE

  5. 3. Sensorimotor function following anterior cruciate ligament injury : movement control, proprioception and neuropsychological perspectives

    Author : Adam Grinberg; Charlotte Häger; Martin Björklund; Dario G. Liebermann; Clare Ardern; Umeå universitet; []

    Abstract : Background: The high incidence of anterior cruciate ligament (ACL) injuries in sports suggests an involvement of both biomechanical and neurocognitive risk factors. Athletes are constantly exposed to challenging sports scenarios, which are often characterised by high-intensity movements combined with a multi-stimuli environment and continuous psychological pressure.

    Author : Lovisa Case; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The information processing associated with wakefulness occurs during what is commonly referred to as a cortical desynchronized state. In contrast, deep sleep is accompanied by slow, synchronized electrical activity, perhaps best exemplified by the slow (... READ MORE
