Cognitive Neuroscience of Attention Deficit Hyperactivity Disorder (ADHD) and Its Clinical Translation

Frontiers in Human Neuroscience, Год журнала: 2018, Номер 12

This review focuses on the cognitive neuroscience of Attention Deficit Hyperactivity Disorder (ADHD) based functional magnetic resonance imaging (fMRI) studies and recent clinically relevant applications such as fMRI-based diagnostic classification or neuromodulation therapies targeting fMRI deficits with neurofeedback (NF) brain stimulation. Meta-analyses executive functions (EFs) show that ADHD patients have cognitive-domain dissociated complex multisystem impairments in several right left hemispheric dorsal, ventral medial fronto-cingulo-striato-thalamic fronto-parieto-cerebellar networks mediate control, attention, timing working memory (WM). There is furthermore emerging evidence for abnormalities orbital ventromedial prefrontal limbic areas motivation emotion control. In addition, poor deactivation default mode network (DMN) suggests an abnormal interrelationship between hypo-engaged task-positive poorly "switched off" hyper-engaged task-negative networks, both which are related to impaired cognition. Translational still its infancy. Pattern recognition analyses attempted provide using data respectable accuracies over 80%. Necessary replication studies, however, outstanding. Brain stimulation has been tested heterogeneously designed, small numbered proof concept key frontal ADHD. Transcranial direct current (tDCS) appears be promising improve symptoms some but larger clinical trials repeated without training needed test efficacy potential costs non-targeted functions. Only three piloted NF dysfunctions near-infrared spectroscopy, two ones finding improvements cognition symptoms, which, were not superior active control conditions, suggesting placebo effects. Neurotherapeutics seems attractive due their safety longer-term neuroplastic effects, drugs cannot offer. However, they need thoroughly short- individualized treatment.

Targeting the affective brain—a randomized controlled trial of real-time fMRI neurofeedback in patients with depression

Neuropsychopharmacology, Год журнала: 2018, Номер 43(13), С. 2578 - 2585

Functional magnetic resonance imaging neurofeedback (fMRI-NF) training of areas involved in emotion processing can reduce depressive symptoms by over 40% on the Hamilton Depression Rating Scale (HDRS). However, it remains unclear if this efficacy is specific to feedback from emotion-regulating regions. We tested a single-blind, randomized, controlled trial upregulation (NFE) yields superior compared control region activated visual scenes (NFS). Forty-three moderately severely depressed medicated patients were randomly assigned five sessions augmentation treatment either NFE or NFS training. At primary outcome (week 12) no significant group mean HDRS difference was found (B = -0.415 [95% CI -4.847 4.016], p 0.848) for 32 completers (16 per group). across groups decreased 43%, and 38% remitted. These improvements lasted until follow-up 18). Both upregulated target regions similar extent. Further, clinical improvement correlated with an increase self-efficacy scores. interpretation limited due lack sham-control group. thus surveyed effects reported accepted therapies depression. Data indicated that our findings exceed expected regression placebo have been drug trials other sham-controlled high-technology interventions. Taken together, we suggest experience successful self-regulation during fMRI-NF may be therapeutic. conclude effective depression, higher provide alternative.

Real‐time fMRI neurofeedback in adolescents with attention deficit hyperactivity disorder

Human Brain Mapping, Год журнала: 2017, Номер 38(6), С. 3190 - 3209

Abstract Attention Deficit Hyperactivity Disorder (ADHD) is associated with poor self‐control, underpinned by inferior fronto‐striatal deficits. Real‐time functional magnetic resonance neurofeedback (rtfMRI‐NF) allows participants to gain self‐control over dysregulated brain regions. Despite evidence for beneficial effects of electrophysiological‐NF on ADHD symptoms, no study has applied the spatially superior rtfMRI‐NF neurotherapy ADHD. A randomized controlled trial tested efficacy right prefrontal cortex (rIFG), a key region that compromised in and upregulated psychostimulants, improvement cognition, inhibitory fMRI activation. To control region‐specificity, an active group received left parahippocampal gyrus (lPHG). Thirty‐one boys were randomly allocated had learn upregulate their target average 11 runs 2 weeks.

Both NF groups showed significant linear activation increases increasing number respective regions reduction symptoms after at 11‐month follow‐up. Only targeting rIFG, however, effect, which correlated symptom reductions, improved trend level sustained attention, increased IFG during task.

Assessment of mental stress effects on prefrontal cortical activities using canonical correlation analysis: an fNIRS-EEG study

Biomedical Optics Express, Год журнала: 2017, Номер 8(5), С. 2583 - 2583

Опубликована: Апрель 19, 2017

This paper presents an investigation about the effects of mental stress on prefrontal cortex (PFC) subregions using simultaneous measurement functional Near-Infrared Spectroscopy (fNIRS) and Electroencephalography (EEG) signals. The aim is to explore canonical correlation analysis (CCA) technique study relationship among bi-modality signals in assessment, how we could fuse for better accuracy detection. Twenty-five male healthy subjects participated while performing arithmetic task under control (under time pressure with negative feedback) conditions. fusion brain acquired by fNIRS-EEG was performed at feature-level CCA maximizing inter-subject covariance across modalities. result discovered associations modalities estimated components responsible these associations. experiment results showed that experienced this cohort subregion specific localized right ventrolateral PFC subregion. These suggest as a suitable candidate region extract biomarkers performance indicators neurofeedback training coping.
