Executive function deficits and neural discordance in children with Autism Spectrum Disorders.

OBJECTIVE This study examined neurophysiologic activities, executive dysfunctions, and their association in children with Autism Spectrum Disorders (ASD). METHODS Thirty-eight normal and 16 children with ASD participated with parental consent. Executive functions were measured using neuropsychological tests and parent ratings, and neurophysiologic activities were measured using EEG to yield cordance values, an indirect measure of brain perfusion. RESULTS Children with ASD made significantly more intrusion errors and False Alarms on the Hong Kong List Learning Test (HKLLT) and Object Recognition Test (OR) than normal children, but were comparable to normal children on the Rey-Osterrieth Complex Figure Test and Continuous Performance Test. They also showed significantly poorer executive functions in everyday activities as shown on the Behavior Rating Inventory of Executive Function (BRIEF), and had lower frontal perfusion patterns than normal children as shown in the neurophysiologic cordance measures. Frontal cordance values were found to be significantly associated with executive dysfunctions in HKLLT Delayed Intrusions, OR False Alarms and BRIEF. CONCLUSIONS Children with ASD were impaired in everyday executive functioning and response inhibition. The cordance value, which has been shown to correlate with brain perfusion in a number of studies, was significantly correlated with executive dysfunctions. SIGNIFICANCE Exploration of this measure as an index for response to intervention is warranted.

Quantitative electroencephalographic profiles for children with autistic spectrum disorder.

The present study examined quantitative electroencephalographic (QEEG) profile for children with autistic spectrum disorder (ASD). Five-minute QEEG data were obtained from 90 normal controls (NCs) and 66 children with ASD. Spectrum analyses revealed that ASD children showed significantly less relative alpha and more relative delta than NC. Specifically, 26% of ASD children and 2% of NCs showed 1.5 SDs of relative alpha below the normative mean. Children with this QEEG profile had 17 times the risk of having ASD than those without such a profile. Sensitivity and specificity of relative alpha were 91% and 73%, respectively. Split-half cross-validation yielded a sensitivity of 76%.

Shaolin Dan Tian Breathing Fosters Relaxed and Attentive Mind: A Randomized Controlled Neuro-Electrophysiological Study

Neuro-electrophysiological studies on meditative breathing revealed its association with either a relaxed or an attentive state. The present study aimed to investigate whether the Shaolin Dan Tian Breathing (DTB) technique, which consists of the Passive and Active subtypes and can be considered as a relaxation exercise and Qigong, would induce both relaxed and attentive states. Twenty-two adults and 22 age-, gender- and education-matched controls received training on the Shaolin DTB (experimental group) and the progressive muscle relaxation respectively for one month. Eyes-closed resting EEG data before and immediately after each type of breathing were obtained individually at baseline and after one-month training. At baseline, the EEG changes after the Shaolin DTB between both groups were comparable. After one-month training, participants in the experimental, but not the control, group showed enhanced temporal alpha asymmetry (an index of relaxation and positive mood) after performing the Passive DTB for five minutes, and enhanced intra- and inter-hemispheric theta coherence (an index of attention and alertness) after performing the Active DTB. The present findings suggested a positive effect of the Shaolin DTB technique on enhancing human neural activity and connectivity, which may possibly enhance mood state and cognitive functions.

Dejian Mind-Body Intervention on Depressive Mood of Community-Dwelling Adults: A Randomized Controlled Trial

The present study evaluated the effectiveness of a short-term mind-body intervention program on improving the depressive mood of an adult community sample. Forty adult volunteers with various degrees of depressive mood were randomly assigned to the experimental group (Dejian Mind-Body Intervention, DMBI) and control group (Cognitive-Behavioral Therapy, CBT). For each group, a total of four 90-min weekly sessions were conducted. Treatment-related changes were measured using the Beck Depression Inventory (BDI-II), an electroencephalographic indicator of positive affect (i.e., prefrontal activation asymmetry), and self-report ratings on physical health. Results indicated that both the DMBI and the CBT group demonstrated significant reduction in depressive mood. However, among individuals with moderate to severe depressive mood at baseline, only those in the DMBI but not the CBT group showed significant reduction in depressive mood. Besides, only the DMBI group demonstrated a significant increase in prefrontal activation asymmetry, suggesting increase in positive affect. While most psychological therapies for depressive mood normally take several months to show treatment effect, the present findings provided initial data suggesting that the DMBI was effective in improving depressive mood of community adults after 1 month of training.

A Chinese mind-body exercise improves self-control of children with autism: A randomized controlled trial

Self-control problems commonly manifest as temper outbursts and repetitive/rigid/impulsive behaviors, in children with autism spectrum disorders (ASD), which often contributes to learning difficulties and caregiver burden. The present study aims to compare the effect of a traditional Chinese Chan-based mind-body exercise, Nei Yang Gong, with that of the conventional Progressive Muscle Relaxation (PMR) technique in enhancing the self-control of children with ASD. Forty-six age- and IQ-matched ASD children were randomly assigned to receive group training in Nei Yang Gong (experimental group) or PMR (control group) twice per week for four weeks. The participants’ self-control was measured by three neuropsychological tests and parental rating on standardized questionnaires, and the underlying neural mechanism was assessed by the participants’ brain EEG activity during an inhibitory-control task before and after intervention. The results show that the experimental group demonstrated significantly greater improvement in self-control than the control group, which concurs with the parental reports of reduced autistic symptoms and increased control of temper and behaviors. In addition, the experimental group showed enhanced EEG activity in the anterior cingulate cortex, a region that mediates self-control, whereas the PMR group did not. The present findings support the potential application of Chinese Chan-based mind-body exercises as a form of neuropsychological rehabilitation for patients with self-control problems.

A Chinese Chan-based mind–body intervention for patients with depression

BACKGROUND Given the recent growing interest and encouraging findings in studies of alternative treatments for depression, the present randomized controlled trial study aimed to compare the effect of a newly developed Chinese Chan-based Dejian Mind-Body Intervention (DMBI) with the Cognitive Behavioral Therapy (CBT) on improving depressive symptoms in patients with depression. METHODS Seventy-five participants diagnosed with major depressive disorder were randomly assigned to receive either 10-session CBT or DMBI, or placed on a waitlist. Pre-post measurements included record of anti-depressants treatment, ratings by psychiatrists who were blinded to the experimental design and self-report on mood measures, and performance in a cognitive test tapping concentration ability. RESULTS Both the CBT and DMBI groups demonstrated significantly reduced overall depressive syndrome after intervention at large effect size (0.93-1.10). Furthermore, the DMBI group (p<0.05), but not the CBT or waitlist groups, demonstrated significant reduction in intake of anti-depressants, and significant improvement in specific depression-related symptoms including difficulty in concentration (p=0.002), and problems in gastrointestinal health (p=0.02) and overall sleep quality (p<0.001). LIMITATIONS This study has provided some evidence for the short-term effect of the DMBI on Chinese population. Its long-term effect on a larger sample and on Caucasian population warrants further investigation. CONCLUSIONS The present findings suggest that a Chinese Chan-based Mind-Body intervention has positive effects on improving mood and health conditions of individuals with depression.

Dejian Mind-Body Intervention Improves the Cognitive Functions of a Child with Autism

There has been increasing empirical evidence for the enhancing effects of Dejian Mind-Body Intervention (DMBI), a traditional Chinese Shaolin healing approach, on human frontal brain activity/functions, including patients with autism who are well documented to have frontal lobe problems. This study aims to compare the effects of DMBI with a conventional behavioural/cognitive intervention (CI) on enhancing the executive functions and memory of a nine-year-old boy with low-functioning autism (KY) and to explore possible underlying neural mechanism using EEG theta cordance. At post-one-month DMBI, KYs inhibitory control, cognitive flexibility, and memory functioning have significantly improved from “severely-to-moderately impaired” to “within-normal” range. This improvement was not observed from previous 12-month CI. Furthermore, KY showed increased cordance gradually extending from the anterior to the posterior brain region, suggesting possible neural mechanism underlying his cognitive improvement. These findings have implicated potential applicability of DMBI as a rehabilitation program for patients with severe frontal lobe and/or memory disorders.

A Chinese Chan-Based Mind-Body Intervention Improves Sleep on Patients with Depression: A Randomized Controlled Trial

Sleep disturbance is a common problem associated with depression, and cognitive-behavioral therapy (CBT) is a more common behavioral intervention for sleep problems. The present study compares the effect of a newly developed Chinese Chan-based intervention, namely Dejian mind-body intervention (DMBI), with the CBT on improving sleep problems of patients with depression. Seventy-five participants diagnosed with major depressive disorder were randomly assigned to receive 10 weekly sessions of CBT or DMBI, or placed on a waitlist. Measurements included ratings by psychiatrists who were blinded to the experimental design, and a standardized questionnaire on sleep quantity and quality was obtained before and after the 10-week intervention. Results indicated that both the CBT and DMBI groups demonstrated significantly reduced sleep onset latency and wake time after sleep onset (effect size range = 0.46–1.0, P ≤ 0.05) as compared to nonsignificant changes in the waitlist group (P > 0.1). Furthermore, the DMBI group, but not the CBT or waitlist groups, demonstrated significantly reduced psychiatrist ratings on overall sleep problems (effect size = 1.0, P = 0.00) and improved total sleep time (effect size = 0.8, P = 0.05) after treatment. The present findings suggest that a Chinese Chan-based mind-body intervention has positive effects on improving sleep in individuals with depression.

Dejian mind-body intervention improves the functioning of a patient with chronic epilepsy: a case report

BackgroundThis is a case report that illustrates the effect of the Dejian Mind-Body Intervention (DMBI) on a 22-year-old chronic epileptic male (onset at age two) suffering from severe cognitive impairments as a result of a serious seizure two years ago. The DMBI is a healing program developed for modern lifestyle based on the traditional Chinese Shaolin Chanwuyi healing approach.Case PresentationThrough a four-month treatment in which he adopted the DMBI specified vegetarian diet, applied an herbal remedy, and practiced Natural Dan Tian Breathing (a type of mind-body exercise), the patient showed significant improvements in language, memory, attention, behavioral initiation, emotional control, social functioning, and overall quality of life. In addition, the DMBI has a positive effect on his brain electrophysiological activities, as indicated by his suppressed delta power (slow wave) and enhanced alpha power (fast wave), and his elevated cordance value (an index associated with cerebral perfusion) in the left frontal and temporal regions. Such neural activity alteration was in line with his observed cognitive improvements.ConclusionThese results provide evidence to support the therapeutic effect of the DMBI and its potential clinical application on treating chronic neurological patients.

A Randomized Controlled Neurophysiological Study of a Chinese Chan-Based Mind-Body Intervention in Patients with Major Depressive Disorder

Our previous studies have reported the therapeutic effects of 10-session Chinese Chan-based Dejian mind-body interventions (DMBI) in reducing the intake of antidepressants, improving depressive symptoms, and enhancing the attentional abilities of patients with depression. This study aims to explore the possible neuroelectrophysiological mechanisms underlying the previously reported treatment effects of DMBI in comparison with those of cognitive behavioral therapy (CBT). Seventy-five age-, gender-, and education-matched participants with depression were randomly assigned to receive either CBT or DMBI or placed on a waitlist. Eyes-closed resting EEG data were obtained individually before and after 10 weeks. After intervention, the DMBI group demonstrated significantly enhanced frontal alpha asymmetry (an index of positive mood) and intra- and interhemispheric theta coherence in frontoposterior and posterior brain regions (an index of attention). In contrast, neither the CBT nor the waitlist group showed significant changes in EEG activity patterns. Furthermore, the asymmetry and coherence indices of the DMBI group were correlated with self-reported depression severity levels and performance on an attention test, respectively. The present findings provide support for the effects of a Chinese Chan-based mind-body intervention in fostering human brain states that can facilitate positive mood and an attentive mind.
