Gait control in children with attention-deficit/hyperactivity disorder.

Gait control in children with attention-deficit/hyperactivity disorder. Hum Mov Sci. 2020 Apr;70:102584 Authors: Simmons RW, Taggart TC, Thomas JD, Mattson SN, Riley EP Abstract The current profile of gait control in children with ADHD is incomplete and predominately based on children walking forward at a self-selected pace. There are no studies of potential gait deficits in this clinical population when walking in different directions in combination with varying rates of stepping that are freely selected and entrained to an external stimulus. The purpose of the current study was to address this lack of information by assessing gait of children aged 7-17 years with (n = 17) and without (n = 26) ADHD. Participants walked forward and backward along an electronically instrumented carpet at a self-selected stepping rate and in synchrony to a metronome that dictated an increased and decreased stepping rate. Using repeated measures analysis of covariance (ANCOVA) to assess spatiotemporal gait parameters, results showed that children with ADHD exhibited a significantly exaggerated, toes 'turned out,' foot position for all walking conditions compared to typically developing children. When walking backward, children with ADHD produced an increased step width, higher stepping cadence, and increased velocity. Additionally, coefficient of variation ratios indicated that children with ADHD produced greater variability of velocity, cadence, an...

Authors: CichoĊ„ L, Janas-Kozik M, Siwiec A, Rybakowski JK Abstract Bipolar disorder (BD) is characterized by pathological changes in mood as well as recurring episodes of mania, hypomania, depression and mixed symptoms. In recent years, the number of BD diagnoses has risen considerably in children and adolescents. Itis believed that anaverage rate of prevalence of bipolar spectrum disorder in the pediatric population is 1.8%, and BD type I - 1.2%, and the prevalence of the disorder increases with the age of patients. Despite the same diagnostic criteria, there are premises that suggest thatthe symptoms of the diso...

This study aims to examine the co-occurrence rate of attention deficit hyperactivity disorder (ADHD) and adrenal gland disorders, as well as whether pharmacotherapy may affect ADHD patients’ risk of developing adrenal gland disorder. One group of patients newly diagnosed with ADHD (n = 75,247) and one group of age- and gender-matching controls (n = 75,247) were chosen from Taiwan′s National Health Insurance database during the period of January 1999 to December 2011. Both patients and controls were monitored through December 31, 2011, in order to identify the occurrence of adrenal gland disorders (ICD-9...

This study aimed to evaluate the efficacy and tolerability of resveratrol (that have been shown to have antioxidative, anti-inflammatory, and anti-apoptotic effects) as an adjunct to methylphenidate in pharmacologic treatment of ADHD. This 8-week, double-blinded, placebo-controlled trial randomized 66 participants to receive either 500  mg/day resveratrol or matched placebo in addition to methylphenidate. ADHD symptoms were evaluated in the patients using the Parent and Teacher versions of ADHD-Rating Scale (ADHD-RS) at three measurement points with time intervals of 4 weeks. Furthermore, the tolerability of the ...

OBJECTIVE: Attention deficit hyperactivity disorder (ADHD) is one of the most common problems in adolescents. Risky behaviors in patients with ADHD are due to impaired impulse control resulting from problems with inhibition of proponent responses, controll...

(University of Southampton) A team of researchers from the University of Southampton, the University of Bath and King's College London, including Dennis Golm from the University of Southampton, have provided compelling evidence of the impact of adversity in childhood on neuropsychological functioning in adulthood. They also showed that neuropsychological difficulties may explain why early adversity is linked to attention deficit hyperactivity disorder (ADHD) in later life.

AbstractPurpose of ReviewCannabis exposure during critical windows of development may have intergenerational physiological consequences disrupting epigenetic programming and marks. This review examines the literature relating to pre-gestational and prenatal cannabinoid exposure and its effect on genes and molecular pathways related to the development of psychiatric disease.Recent FindingsDevelopmental cannabis exposure alters epigenetic processes with functional gene consequences. These include potentially heritable alterations in genes and molecular pathways critical for brain development and associated with autism spectr...

Abstract Despite the pervasive nature of various forms of impairment associated with attention-deficit/hyperactivity disorder (ADHD), the precise nature of their associations with ADHD and related sluggish cognitive tempo (SCT), particularly at the heterogeneous item level, remains ambiguous. Using innovative network analysis techniques, we sought to identify and examine the concurrent validity of ADHD and SCT bridge items (i.e., those demonstrating the most robust relations with various forms of impairment) with respect to Overall, Home-School, and Community-Leisure impairment domains. Parents of a nationally rep...
