AbstractA preliminary experimental study examined brain wave frequency patterns of female participants (N = 14) engaged in two different art making conditions: clay sculpting and drawing. After controlling for nonspecific effects movement, quantitative electroencephalographic (qEEG) recordings were made the bilateral medial frontal cortex parietal each participant. Results showed that both drawing increased gamma power right lobe compared to general unlike drawing, decreased elevated theta...

Attention-deficit/hyperactivity disorder is characterized by neurobiological heterogeneity, possibly explaining why not all patients benefit from a given treatment. As means to select the right treatment (stratification), biomarkers may aid in personalizing prescription, thereby increasing remission rates.The biomarker this study was developed heterogeneous clinical sample (N = 4249) and first applied two large transfer datasets, priori stratifying young males (<18 years) with higher...

The quantitative electroencephalographic (QEEG) theta/beta power ratio (TBR) has been shown to have an association with attention-deficit hyperactivity disorder (ADHD), a previous tacit assumption of equivalence across hardware and software systems. Therefore, the International Collaborative ADHD Neurofeedback (ICAN) randomized clinical trial used fixed TBR ≥ 4.5 cutoff as measured by Thought Technology Monastra-Lubar Assessment Suite inclusion criterion, 1.5 SD above norms collected that...

Abstract There has been ongoing research on the ratio of theta to beta power (Theta/Beta Ratio, TBR) as an EEG-based test in diagnosis ADHD. Earlier studies reported significant TBR differences between patients with ADHD and controls. However, a recent meta-analysis revealed marked decline effect size for difference controls published past decade. Here, we if EEG processing explain heterogeneity findings. We analyzed data from two multi-center clinical studies. Five different signal...

Objective: To Explore whether subtypes and comorbidities of attention-deficit hyperactivity disorder (ADHD) induce distinct biases in cognitive components involved information processing. Method: Performance on the Integrated Visual Auditory Continuous Test (IVA-CPT) was compared between 150 children (aged 7 to 10) with ADHD, grouped by DSM-5 presentation (ADHD-C, ADHD-I) or co-morbid diagnoses (anxiety, oppositional defiant [ODD], both, neither), 60 without ADHD. Diffusion decision modeling...

Background Exploring whether cognitive components (identified by baseline testing and computational modeling) moderate clinical outcome of neurofeedback (NF) for attention-deficit hyperactivity disorder (ADHD).Method 142 children (aged 7–10) with ADHD were randomly assigned to either NF (n = 84) or control treatment 58) in a double-blind trial (NCT02251743). The group received live, self-controlled downtraining electroencephalographic theta/beta ratio power. identical-appearing reinforcement...

The EEG theta band displays distinct roles in resting and task states. Low transient increases frontal-midline (fm) power during tasks are associated with better cognitive control, such as error monitoring. ADHD can disrupt this balance, resulting high linked to drowsiness low fm-theta activity reduced abilities. Theta/beta ratio (TBR) neurofeedback aims normalize state by downregulating theta, which could potentially unfavorably affect task-related fm-theta. This study examines the TBR...

In the Handbook of Neurofeedback, Dynamics and Clinical Application, James Evans has done an excellent job bringing together a diverse array information from respectable group contributors. The book's intended audience ranges those interested in entering field to experienced clinicians. A minimal acquaintance with concepts biofeedback, electroencephalography (EEG), quantitative EEG (QEEG) will make material readily comprehended by most readers. chapters are written various professionals...

Abstract Introduction: We examined psychiatric comorbidities moderation of a 2-site double-blind randomized clinical trial theta/beta-ratio (TBR) neurofeedback (NF) for attention deficit hyperactivity disorder (ADHD). Methods: Seven-to-ten-year-olds with ADHD received either NF (n=84) or Control (n=58) 38 treatments. Outcome was change in parent-/teacher-rated inattention from baseline to end-of-treatment (acute effect), and 13-month-follow-up. Seventy percent had at least one comorbidity:...
