Visual disorders with psychostimulants: A paediatric case report.

Methylphenidate- and amphetamine-based psychostimulants are the most common medications used to treat the symptoms of attention-deficit/hyperactivity disorder in children. Ocular side effects including dry eyes, mydriasis, accommodation disturbance, and blurry vision are listed in the product monograph but interestingly, are rarely reported in the paediatric literature. Our patient, a 9-year-old boy, presented a significant decrease in visual acuity secondary to accommodation disorder after being treated with methylphenidate hydrochloride controlled release (Biphentin) and lisdexamfetamine (Vyvanse).

Screening for disruptive behaviour problems in preschool children in primary health care settings.

Disruptive behaviour problems in preschool children are significant risk factors for, and potential components of, neurodevelopmental and mental health disorders. Some noncompliance, temper tantrums and aggression between 2 and 5 years of age are normal and transient. However, problematic levels of disruptive behaviour, specifically when accompanied by functional impairment and/or significant distress, should be identified because early intervention can improve outcome trajectories.

Behaviour disorders in children with an intellectual disability.

Behaviour disorders are frequent in children with an intellectual disability, regardless of the underlying etiology. They are often disabling, and can create problems in everyday life and can mask, or reveal, an organic or psychiatric illness. Such behaviours are often chronic and more than one may be present in the same individual.

Persistent Handwriting Difficulties in Children With ADHD After Treatment With Stimulant Medication.

Objective: Children with ADHD often present with handwriting difficulties. However, the extent to which motor and attention skills influence performance in this group has not yet been explored. The objective of this study was to examine the factors associated with change in handwriting performance.

Motor skills of children newly diagnosed with Attention Deficit Hyperactivity Disorder prior to and following treatment with stimulant medication.

Motor difficulties are common in children with Attention Deficit Hyperactivity Disorder (ADHD). Although preliminary evidence has suggested that methylphenidate can improve the motor skills in children with ADHD and Developmental Coordination Disorder (DCD), the effect of stimulant medication on motor performance in children newly diagnosed with ADHD with or without motor impairment remains unclear. A cohort study of 49 medication-naïve children (39 male; mean age 8.

Serotonergic contribution to boys' behavioral regulation.

Objectives: Animal and human adult studies reveal a contribution of serotonin to behavior regulation. Whether these findings apply to children is unclear. The present study investigated serotonergic functioning in boys with a history of behavior regulation difficulties through a double-blind, acute tryptophan supplementation procedure.

Handwriting capacity in children newly diagnosed with Attention Deficit Hyperactivity Disorder.

Unlabelled: Preliminary evidence suggests that children with Attention Deficit Hyperactivity Disorder (ADHD) may exhibit handwriting difficulties. However, the exact nature of these difficulties and the extent to which they may relate to motor or behavioural difficulties remains unclear. The aim of this study was to describe handwriting capacity in children newly diagnosed with ADHD and identify predictors of performance.

Omega-3 fatty acid treatment of children with attention-deficit hyperactivity disorder: A randomized, double-blind, placebo-controlled study.

Background: Although several clinical trials have evaluated the impact of n-3 polyunsaturated fatty acid (PUFA) on patients with attention-deficit hyperactivity disorder (ADHD), changes in plasma PUFA composition were not always assessed following n-3 supplementation. Furthermore, no reports are available on the efficacy of n-3 PUFA in Canadian youth with ADHD.

Objectives: To determine fatty acid (FA) composition, and the efficacy and safety of n-3 PUFA supplementation on ADHD clinical symptoms in French Canadian primary school children.
