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…

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.…

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…

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…

Objective: To examine the effects of triple beaded mixed amphetamine salts (TB MAS) on ADHD and executive dysfunction symptoms throughout the day in adults with DSM-5 ADHD. Method: This was a 6 week, single-blind, placebo-lead in trial of TB MAS (12.5-37.5 mg/day); all participants received 2 weeks of single-blind placebo); one individual was a…

Objective: The objective was to determine the differential validity of a cognitive disengagement syndrome-only (CDS-only) group from ADHD-inattentive presentation-only (IN-only), ADHD-hyperactive-impulsive presentation-only (HI-only), and ADHD-combined presentation (C-only) groups within childhood (ages 5-10) and adolescence (ages 11-16). Methods:…

Increasing evidence highlights the role of disrupted circadian rhythms in the neural dysfunctions and sleep disturbances observed in autism spectrum disorder and attention-deficit/hyperactivity disorder. However, the causality and directionality of these associations remain unclear. In this study, we employed a bidirectional two-sample Mendelian…

Background: ADHD is a generally persistent neurodevelopmental condition that can have significant consequences if left untreated, and medication, often in conjunction with psychotherapy, is the first-line treatment with well-established efficacy. Adolescents and young adults (AYAs) represent a particularly vulnerable and understudied subgroup and…

The current study examined how individuals with neurodevelopmental disorders navigate the complexities of learning within multidimensional environments marked by uncertain dimension values and without explicit guidance. Participants engaged in a game-like complex reinforcement learning task in which the stimuli dimension determining reward…

Objective: Investigate whether patterns of heart rate variability (indexed via respiratory sinus arrhythmia) and visual attention at 12 to 18 months of age predict elevated ADHD symptoms, autism, or neither during the preschool period. Method: Ninety infants 12 to 18 months of age (M = 17.27, SD = 1.93; 36 females; 82.2% non-Hispanic) participated…
