“…Seed-to-Voxel Analysis. As shown in Table 2 and Figure 1, IA individuals exhibited enhanced rsFC of the right VRP with the left premotor cortex (PMC), orbitofrontal cortex (OFC), cerebellum, and right ventromedial prefrontal 3 Neural Plasticity cortex (vmPFC) in comparison to HCs (p < 0:05, FDR corrected, cluster size > 621 mm 3 ). No significant connectivity alteration was found in the left VRP or bilateral VSi or VSs.…”

“…The IAT and the visual analogue scale (VAS) [25] were fulfilled by IA subjects to assess the symptom severity and the Internet craving, respectively, before and after the acupuncture treatment. 3 . Two hundred and fifty-five volumes of image were obtained, and each of the volumes included thirty-five axial slices.…”

“…Epidemiologic research among young people has shown that the prevalence rate of IA is as high as 34.4% in some areas [2]. In the last 10 years, the prevalence rate of IA has sharply increased from 3.0% to 26.8% in Hong Kong, with the proportion of heavy Internet users increasing from 25.4% to 42.0% [3].…”

Purpose. Acupuncture is an effective therapy for Internet addiction (IA). However, the underlying mechanisms of acupuncture in relieving compulsive Internet use remain unknown. Neuroimaging studies have demonstrated the role of the ventral striatum (VS) in the progress of IA; hence, the aim of this study was to explore the effects of acupuncture on the resting-state functional connectivity (rsFC) and relevant network of VS in IA. Methods. Twenty-seven IA individuals and 30 demographically matched healthy control subjects (HCs) were recruited in this study. We acquired the functional magnetic resonance imaging (fMRI) data in IA subjects before and after 40 days of acupuncture treatment. Seed-to-voxel and ROI-to-ROI analyses were applied to detect the rsFC alterations of the VS and related network in IA subjects and to investigate the modulation effect of acupuncture on the rsFC. Results. Compared with HCs, IA subjects exhibited enhanced rsFC of the right ventral rostral putamen (VRP) with the left orbitofrontal cortex (OFC), premotor cortex (PMC), cerebellum, and right ventromedial prefrontal cortex (vmPFC). In the network including these five ROIs, IA also showed increased ROI-to-ROI rsFC. Using a paired t-test in IA subjects before and after 40 days of acupuncture, the increased ROI-to-ROI rsFC was decreased (normalized to HC) with acupuncture, including the rsFC of the right VRP with the left OFC, PMC, and cerebellum, and the rsFC of the left cerebellum with the left OFC, PMC, and right vmPFC. Furthermore, the change in rsFC strength between the right VRP and left cerebellum in IA individuals was found positively correlated with the Internet craving alleviation after acupuncture. Conclusions. These findings verified the modulation effect of acupuncture on functional connectivity of reward and habit systems related to the VS in IA individuals, which might partly represent the underlying mechanisms of acupuncture on IA.

Recent studies have revealed structural and functional abnormalities in amygdala due to internet addiction (IA) associated with emotional disturbance. However, the role of amygdala connectivity that is responsible for emotion-cognition interactions is largely unknown in iA. this study aims to explore the amygdala connectivity abnormalities in iA. the functional and structural connectivity of bilateral amygdala were examined using seed-based connectivity analysis, and the structural integrity on white mater tracts passing through amygdala was also examined. Additionally, a correlation analysis was performed to investigate the relationship between brain connectivity and duration of iA. We found that iA subjects had decreased negative functional connectivity (fc) between amygdala and dorsolateral prefrontal cortex (DLPFC), and had increased negative FC between amygdala and precuneus and superior occipital gyrus (SoG). While iA subjects had decreased positive fc between amygdala and anterior cingulate cortex (ACC), and had increased positive FC between amygdala and thalamus. The FC between left amygdala and right DLPFC had significant correlation with duration of IA. The structural connectivity and integrity between amygdala and Acc were also decreased in iA subjects. these findings indicate that the amygdala connectivity is altered in IA subjects. The altered FC of amygdala-DLpfc is associated with duration of iA. Internet addiction (IA) is a behavioral addiction, which has become a social problem across Eastern and Western societies with a prevalence rate ranging from 1.4% to 20.3% 1. More importantly, the prevalence rate of IA among adolescents has an increasing trend 1,2. IA is generally characterized by a loss of control over the use of the Internet despite its adverse consequences 3. The excessive and compulsive Internet use has accounted for poor real-life performance, affecting daily life function, social relationships, and academic or occupational achievements 4,5. Empirical evidence is accumulating that IA subjects have altered cognitive behaviors and brain structures 6-8. Clinically, IA disorder is closely associated with other psychiatric disorders, such as substance use disorder 9,10 , depression 10 , social anxiety disorder 11 , and attention-deficit hyperactivity disorder 12. Particularly, IA shares some clinical symptoms with them, such as preoccupation, withdrawal, negative mood, and unsuccessful attempts to control 3,13. The similar emotional and cognitive disturbances suggest overlaps in the neurobiological mechanisms underlying IA and these psychiatric disorders. A number of neuroimaging studies have documented that the amygdala played an important role in emotion processing and involved in psychiatric disorders, such as IA associated with emotional disturbance 14-17. In particular, a neuroimaging study investigated the brain grey matter volume using voxel-based morphometry (VBM) and found that the grey matter volume in the amygdala was decreased in IA 14. A resting-state functional magnetic reson...

“…Shek has assembled an outstanding team of Hong Kong investigators to review the evidence on the critical issues that impact the health and development of young people in the region: smoking [2], substance use [3], Internet addiction [4], problem gambling [5], sexual behavior [6], suicide and self-harm [7], and bullying [8] and mental disorders [9]. All the articles tackle these issues through a shared framework, first exploring the prevalence and psychosocial correlates before outlining opportunities for prevention.…”
