P300 change and cognitive behavioral therapy in subjects with Internet addiction disorder A 3-month follow-up study

Event-related potential studies of cognitive function in addiction behaviors have focused on the P300 event-related potential component. The current study investigated the association between P300 component and Internet addiction disorder. We found that individuals with Internet addiction disorder exhibited significantly longer P300 latencies than controls （N2： P = 0.035; P3a： P = 0.031 P3b： P = 0.043） and similar P300 amplitudes compared to control participants. After 3 months of cognitive behavioral therapy, P300 latencies decreased significantly in the P3a and P3b （P3a： P = 0.045; P3b： P = 0.062）. These results suggest that deficits in cognitive function may be involved in Internet addiction disorder, and that clinical psychological treatment may be effective.

Decreased frontal lobe function in people with Internet addiction disorder

In our previous studies, we showed that frontal lobe and brainstem functions were abnormal in online game addicts. In this study, 14 students with Internet addiction disorder and 14 matched healthy controls underwent proton-magnetic resonance spectroscopy to measure cerebral function. Results demonstrated that the ratio of N-acetylaspartate to creatine decreased, but the ratio of cho- line-containing compounds to creatine increased in the bilateral frontal lobe white matter in people with Internet addiction disorder. However, these ratios were mostly unaltered in the brainstem, suggesting that frontal lobe function decreases in people with Internet addiction disorder.

Internet addiction and problematic Internet use: A systematic review of clinical research

AIM: To provide a comprehensive overview of clinical studies on the clinical picture of Internet-use related addictions from a holistic perspective. A literature search was conducted using the database Web of Science.METHODS: Over the last 15 years, the number of Internet users has increased by 1000%, and at the same time, research on addictive Internet use has proliferated. Internet addiction has not yet been understood very well, and research on its etiology and natural history is still in its infancy. In 2013, the American Psychiatric Association included Internet Gaming Disorder in the appendix of the updated version of the Diagnostic and Statistical Manual for Mental Disorders(DSM-5) as condition that requires further research prior to official inclusion in the main manual, with important repercussions for research and treatment. To date, reviews have focused on clinical and treatment studies of Internet addiction and Internet Gaming Disorder. This arguably limits the analysis to a specific diagnosis of a potential disorder that has not yet been officially recognised in the Western world, rather than a comprehensive and inclusive investigation of Internet-use related addictions(including problematic Internet use) more generally. RESULTS: The systematic literature review identified a total of 46 relevant studies. The included studies used clinical samples, and focused on characteristics of treatment seekers and online addiction treatment. Four main types of clinical research studies were identified, namely research involving(1) treatment seeker characteristics;(2) psychopharmacotherapy;(3) psychological therapy; and(4) combined treatment. CONCLUSION: A consensus regarding diagnostic criteria and measures is needed to improve reliability across studies and to develop effective and efficient treatment approaches for treatment seekers.

Functional magnetic resonance imaging of internet addiction in young adults

AIM: To report the results of functional magnetic resonance imaging(f MRI) studies pertaining internet addiction disorder(IAD) in young adults.METHODS: We conducted a systematic review on Pub Med, focusing our attention on f MRI studies involving adult IAD patients, free from any comorbid psychiatric condition. The following search words were used, both alone and in combination: f MRI, internet addiction, internet dependence, functional neuroimaging. The search was conducted on April 20^(th), 2015 and yielded 58 records. Inclusion criteria were the following: Articles written in English, patients' age ≥ 18 years, patients affected by IAD, studies providing f MRI results during resting state or cognitive/emotional paradigms. Structural MRI studies, functional imaging techniques other than f MRI, studies involving adolescents, patients with comorbid psychiatric, neurological or medical conditions were excluded. By reading titles and abstracts, we excluded 30 records. By reading the full texts of the 28 remaining articles, we identified 18 papers meeting our inclusion criteria and therefore included in the qualitative synthesis.RESULTS: We found 18 studies fulfilling our inclusion criteria, 17 of them conducted in Asia, and including a total number of 666 tested subjects. The included studies reported data acquired during resting state or different paradigms, such as cue-reactivity, guessing or cognitive control tasks. The enrolled patients were usually males(95.4%) and very young(21-25 years). The most represented IAD subtype, reported in more than 85% of patients, was the internet gaming disorder, or videogame addiction. In the resting state studies, the more relevant abnormalities were localized in the superior temporal gyrus, limbic, medial frontal and parietal regions. When analyzing the task related fmri studies, we found that less than half of the papers reported behavioral differences between patients and normal controls, but all of them found significant differences in cortical and subcortical brain regions involved in cognitive control and reward processing: Orbitofrontal cortex, insula, anterior and posterior cingulate cortex, temporal and parietal regions, brain stem and caudate nucleus.CONCLUSION: IAD may seriously affect young adults' brain functions. It needs to be studied more in depth to provide a clear diagnosis and an adequate treatment.

Increased regional homogeneity in internet addiction disorder： a resting state functional magnetic resonance imaging study

Background Internet addition disorder （lAD） is currently becoming a serious mental health problem among Chinese adolescents. The pathogenesis of lAD, however, remains unclear. The purpose of this study applied regional homogeneity （ReHo） method to analyze encephalic functional characteristic of lAD college students under resting state. Methods Functional magnetic resonanc image （fMRI） was performed in 19 lAD college students and 19 controls under resting state. ReHo method was used to analyze the differences between the average ReHo in two groups. Results The following increased ReHo brain regions were found in lAD group compared with control group： cerebellum, brainstem, right cingulate gyrus, bilateral parahippocampus, right frontal lobe （rectal gyrus, inferior frontal gyrus and middle frontal gyrus）, left superior frontal gyrus, left precuneus, right postcentral gyrus, right middle occipital gyrus, right inferior temporal gyrus, left superior temporal gyrus and middle temporal gyrus. The decreased ReHo brain regions were not found in the lAD group compared with the control group. Conclusions There are abnormalities in regional homogeneity in lAD college students compared with the controls and enhancement of synchronization in most encephalic regions can be found. The results reflect the functional change of brain in lAD college students. The connections between the enhancement of synchronization among cerebellum, brainstem, limbic lobe, frontal lobe and apical lobe may be relative to reward pathways.

Effect of electro-acupuncture combined with psychological intervention on mental symptoms and P50 of auditory evoked potential in patients with internet addiction disorder

OBJECTIVE: To observe the therapeutic effects of electro-acupuncture(EA) combined with psychological intervention on the symptom of somzatization or obsession and mental symptom of depression or anxiety and P50 of Auditory Evoked Potential(AEP) on internet addiction disorder(IAD).METHODS: One hundred and twenty cases of IAD were randomly divided into an EA group, a psycho-intervention(PI) group and a comprehensive therapy(EA plus PI) group. Patients in the EA group were treated with EA. Patients in the PI group were treated with cognition and behavior therapy. Patients in the EA plus PI group were treated with electro-acupuncture plus psychological intervention. Scores of IAD, scores of the symptom checklist90(SCL-90), latency and amplitude of P50 of AEP were measured before and after treatment.RESULTS: The scores of IAD after treatment significantly decreased in all groups(P < 0.05), and thescores of IAD in the EA plus PI group were significantly lower than those in the other two groups(P < 0.05). The scores of SCL-90 assembled and each factor after treatment in the EA plus PI group significantly decreased(P < 0.05). After treatment in the EA plus PI group, the amplitude distance of S1P50 and S2P50(S1-S2) significantly increased(P < 0.05).CONCLUSION: EA combined with PI could relieve the mental symptoms of IAD patients, and the mechanism is possibly related to the increase of cerebrum sense perception gating function.
