Objective: Neurotypical individuals can prioritize particularly valuable information in working memory. This is a well-replicated effect, demonstrated across a wide variety of task factors and age groups. However, it is not clear if individuals with symptoms of ADHD are able to do this effectively, as there is some evidence this group struggle to…

Background: Attention Deficit Hyperactivity Disorder (ADHD) and Specific Learning Difficulties (SLD) are both associated with attentional and cognitive difficulties. This study examined the extent to which the cognitive impairments could be consequences of elevated levels of inattention and hyperactivity/impulsivity. Method: Secondary analysis was…

Objective: This study aimed to objectively assess signs of hyperactivity in adults suspected of having ADHD, addressing potential sex bias in diagnosis. Methods: About 13,179 (49% female) adults with an average age of 33 years with ADHD and 1,910 (41% female) adults with an average age of 36 years without ADHD were included. Motor activity was…

The moderate brain arousal (MBA) model posits that individuals with (elevated traits of) ADHD have lower levels of neural noise and that auditory random noise can elicit stochastic resonance (SR) and increase neural noise, which improves their cognitive performance. Indeed, research shows that auditory random noise, such as white noise, improves…

Objective: This study aims to verify the therapeutic efficacy and safety of a traditional Chinese medicine, Jingling Oral Liquid, in treating ADHD through a multicenter, randomized, double-blind, placebo-controlled trial (ChiCTR-IPR-17012293). Method: Eighty-five children with ADHD underwent 8 weeks of strictly monitored treatment. Forty children…

Objectives: ADHD is now recognized as a common condition in adulthood, but the evidence supporting a separate characterization of a cognitive profile for ADHD in older adults is scarce. Consequently, the goal of the current study was to conduct a systematic review that helps clarify the cognitive characteristics of ADHD in older individuals.…

Symptoms of inattention (IA), hyperactivity, and impulsivity present in school-aged children are important indications of developmental problems. The assessment of these symptoms largely relies on questionnaires completed by parents, teachers, and the children themselves. However, inherent perceptual biases may lead to inaccuracies in these…

Background: Adult ADHD has increasingly become a focus in adult psychiatry. Despite well-established diagnostic criteria and specific therapeutic approaches, contemporary discussions often dismiss ADHD as a "fad." This study examines Carl Gustav Jung's 1904 concept of "manic mood" and its potential alignment with the modern…

Background: This review aimed to systematically review and synthesize qualitative evidence of the experiences of adults with ADHD who engage in stimulant medication treatment. A secondary aim was to establish the factors that influence adherence behavior regarding stimulant medication treatment for ADHD and appraise the quality of existing…

Purpose: Attention is proposed to consist of three discrete neurofunctional networks, though evidence suggests that two of these -- the alerting and cognitive control networks -- are interdependent. The neural mechanism(s) underlying this interdependence have not been identified; however, the locus coeruleus -- norepinephrine (LC-NE) system may…

Objective: Experiences of "auditory hyper-reactivity" and decreased sound tolerance, which can be separated into phenotypes such as hyperacusis and misophonia, are prevalent in autism and ADHD and impact quality of life and wellbeing. Furthermore, atypical patterns of attention regulations--including hyper-focus and inattention--are…

This study investigated the effectiveness of applying a smartphone to reduce the hyperactive/impulsive behaviors of 3 students with attention deficit hyperactivity disorder (ADHD) in class. A smartphone that can simultaneously provide vibration and visual text prompts was adopted in this study to remind the participants when they exhibited…

Objective: Learning unfolds in distinct stages--acquisition, consolidation, and maintenance--shaped by cognitive mechanisms such as saliency processing, interference control, and sustained attention. ADHD in adults is associated with deficits in these cognitive processes, which in turn might lead to learning difficulties. Method: Using a novel…

Objective: Proneness to boredom has been reported in ADHD populations; however, no study to date has examined potential mediators of ADHD-related boredom. The current study investigated whether individuals with ADHD traits exhibit higher levels of boredom propensity relative to their peers without ADHD traits and explore if attention control and…

Objectives: Although extensive research has documented associations between Attention-Deficit/Hyperactivity Disorder (ADHD) and differences in resting-state electroencephalography (EEG) oscillatory activity, the causal nature of these relationships remains uncertain. This study aimed to determine whether there is a causal relationship between…
