Nano‐Octahedron Cobalt Oxide Decorated Graphene Nanocomposites for the Selective/Simultaneous Detection of Dopamine

open access: yesAdvanced Materials Interfaces, EarlyView.
Nano‐octahedron Co3O4 decorated graphene composite electrode for selective and simultaneous detection of dopamine. The detection limit of 0.09 µM, and linear range from 1 to 500 µM are reported. The synergistic effect of nano octahedron Co3O4 and graphene results in excellent performance of the sensor in terms of selectivity and sensitivity.

Melatonin effects on sleep disorders in children with attention deficit hyperactivity disorder [PDF]

open access: yesReviews in Clinical Medicine, 2014
Attention deficit hyperactivity disorder is one of the most common psychiatric disorders in childhood. Around 25-50% of these children suffered from some kind of sleep disorder especially with chronic form of insomnia.

Executive functioning in adults with attention deficit hyperactivity disorder: A systematic review

open access: yesActa Neurológica Colombiana
Introduction: Executive function deficits are associated with attention deficit hyperactivity disorder (ADHD) in both children and adults. The inattentive subtype is primary related to “cold” executive functions, while the hyperactive subtype is related

Structural Brain Asymmetries in Youths with Combined and Inattentive Presentations of Attention Deficit Hyperactivity Disorder [PDF]

open access: yesarXiv, 2020
Alterations in structural brain laterality are reported in attention-deficit/hyperactivity disorder (ADHD). However, few studies examined differences within presentations of ADHD. We investigate asymmetry index (AI) across 13 subcortical and 33 cortical regions from anatomical metrics of volume, surface area, and thickness.

A Network Theory Investigation into the Altered Resting State Functional Connectivity in Attention-Deficit Hyperactivity Disorder [PDF]

open access: yesarXiv, 2022
In the last two decades, functional magnetic resonance imaging (fMRI) has emerged as one of the most effective technologies in clinical research of the human brain. fMRI allows researchers to study healthy and pathological brains while they perform various neuropsychological functions. Beyond task-related activations, the human brain has some intrinsic

Attention Deficit Hyperactivity Disorder : an overview [PDF]

open access: yes, 2014
Attention Deficit Hyperactivity Disorder (ADHD) is a neurobehavioural disorder found more commonly, but not exclusively, in school-age children. The hallmarks of the condition are inattention and hyperactivity/ impulsivity, which often go together ...

Attention-deficit disorder (attention-deficit/ hyperactivity disorder without hyperactivity): A neurobiologically and behaviorally distinct disorder from attention-deficit/hyperactivity disorder (with hyperactivity) [PDF]

open access: yesDevelopment and Psychopathology, 2005
Most studies of attention-deficit/hyperactivity disorder (ADHD) have focused on the combined type and emphasized a core problem in response inhibition. It is proposed here that the core problem in the truly inattentive type of ADHD (not simply the subthreshold combined type) is in working memory. It is further proposed that laboratory measures, such as

Biological and Mechanical Limitations for Chronic Fast‐Scan Cyclic Voltammetry Sensor Design

open access: yesAdvanced Materials Technologies, EarlyView.
Real‐time detection of neurochemicals has demonstrated value in the field of neuroscience. However, current methods have limitations for use in the chronic setting, which is often the ideal environment for research. This article discusses these limitations, as well as technologies that have been developed to overcome them, and provides recommendations ...

Psychiatric morbidity among men using anabolic steroids

open access: yesDepression and Anxiety, Volume 39, Issue 12, Page 805-812, December 2022., 2022
Abstract Objective The purpose of this study was to investigate the psychiatric morbidity among men with abuse of anabolic steroids. Methods The design is a retrospectively matched cohort study. Five hundred and fourty‐five males, who tested positive for anabolic steroids in Danish fitness centers during the period January 3, 2006 to March 1, 2018 ...
