Beyond Attention-Deficit Hyperactivity Disorder:Exploring Psychiatric Comorbidities and Their Neuropsychological Consequences in Adults

Objectives@#This study aimed to identify the psychiatric comorbidity status of adult patients diagnosed with attention-deficit hyperactivity disorder (ADHD) and determine the impact of comorbidities on neuropsychological outcomes in ADHD. @*Methods@#The study participants were 124 adult patients with ADHD. Clinical psychiatric assessments were performed by two boardcertified psychiatrists in accordance with the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. All participants were assessed using the Mini-International Neuropsychiatric Interview Plus version 5.0.0 to evaluate comorbidities. After screening, neuropsychological outcomes were assessed using the Comprehensive Attention Test (CAT) and the Korean version of the Wechsler Adult Intelligence Scale, Fourth Edition (K-WAIS-IV). @*Results@#Mood disorders (38.7%) were the most common comorbidity of ADHD, followed by anxiety (18.5%) and substance use disorders (13.7%). The ADHD with comorbidities group showed worse results on the Perceptual Organization Index and Working Memory Index sections of the K-WAIS than the ADHD-alone group (p=0.015 and p=0.024, respectively). In addition, the presence of comorbidities was associated with worse performance on simple visual commission errors in the CAT tests (p=0.024). @*Conclusion@#These findings suggest that psychiatric comorbidities are associated with poor neuropsychological outcomes in adult patients with ADHD, highlighting the need to identify comorbidities in these patients.

The Review of Vincent van Gogh’s Mental World and Mental Illness in the Viewpoint of Modern Psychiatry / 신경정신의학

Vincent van Gogh committed suicide at age 37 in July 1890. Although 130 years have passed since his death, his tragic mental illness and dramatic life experience, together with his extraordinary artistic achievements, have fascinated many people, and many physicians have proposed diagnostic hypotheses and related evidence continuously. The diagnoses of physical illnesses included temporal lobe epilepsy, Meniere’s disease, acute intermittent porphyria, tertiary syphilis, absinthe abuse, terpenoid/lead poisoning, glaucoma, cataract, and digitalis intoxication. Possible psychiatric diagnoses include borderline personality disorder, mood disorder with depressivemanic episodes, and schizophrenia. This article reviews the current information on Vincent’s life, letters, medical records, insight into his disease, testimonies of acquaintances, and other evidence and viewpoints on his illness. In summary, Vincent’s premorbid personality showed signs of borderline personality disorder with continuous conflicts with close people. He had long depressive episodes followed by hypomania multiple times throughout his life. Temporal lobe epilepsy has been raised as the principal diagnosis to explain his periodic memory loss, auditory/visual hallucinations, persecutory/religious delusions, and self-injurious behavior. On the other hand, bipolar disorder and schizoaffective disorder are also recognized as core diagnoses due to the expanding concept of mania and hypomania in the late 20th century. The aggravating factors to his symptoms could have been events provoking separation anxiety from Theo and neurotoxic substance abuse, including absinthe. Vincent’s psychiatric symptoms are difficult to explain with a single diagnosis, but the author suggests schizoaffective disorder, bipolar type, showing the characteristics of bipolar disorder and schizophrenia.

Development of the Korean Practice Parameter for Adult Attention-Deficit/Hyperactivity Disorder

Objectives@#Adult attention-deficit/hyperactivity disorder (ADHD) is an important mental health problem that needs resolution, especially considering the high rates of ADHD continuation from childhood to adolescence/adulthood and the high prevalence of ADHD in adults. Adults with ADHD have lifelong negative impacts and require close monitoring with long-term follow-up. Hence, the establishment of a Korean practice parameter for adult ADHD is necessary to minimize discontinuation of treatment and enable information sharing among Korean mental health professionals. @*Methods@#The Korean practice parameter was developed using an evidence-based approach consisting of expert consensus survey coupled with literature review. @*Results@#According to the expert consensus survey, the most commonly used diagnostic methods were clinical psychiatric interview (20.66%) and self-report scales (19.25%) followed by attention (14.71%) and psychological tests (14.24%). Key evaluation instruments currently available in Korea are the World Health Organization Adult ADHD Self-Report Rating Scale, Korean Adult ADHD Rating Scale, Diagnostic Interview for ADHD in Adults, Barkley Deficits in Executive Functioning Scale for adults, Comprehensive Attention Test, Conners’ Continuous Performance Test, and the subtests of Wechsler Adult Intelligence Scale, Digit Span and Letter-Number Sequencing. Although pharmacotherapy is recommended as the first-line of treatment for adult ADHD, we recommend that it be followed by a multimodal and multidisciplinary approach including psychoeducation, pharmacotherapy, cognitive behavior therapy and coaching. @*Conclusion@#The Korean practice parameter introduces not only general information for the diagnosis and treatment of adult ADHD on a global scale, but also the process of diagnosis and treatment options tailored to the Korean population.

Does a Preoperative Temporary Discontinuation of Antiplatelet Medication before Surgery Increase the Allogenic Transfusion Rate and Blood Loss after Total Knee Arthroplasty? / 대한정형외과학회잡지

PURPOSE: The aim of this study was to determine if preoperative temporary discontinuation of antiplatelet medication (aspirin, clopidogrel, or cilostazol) is a safe procedure that does not increase early postoperative bleeding and allogenic blood transfusion after a total knee arthroplasty. MATERIALS AND METHODS: A retrospective analysis was conducted among consecutive patients who underwent navigation assisted primary total knee arthroplasty performed by a single surgeon, from January 2013 to December 2016. A total of 369 patients enrolled in this study were divided into two groups, 271 patients with no history of antiplatelet therapy and 98 patients who underwent 7 days of temporary withdrawal of antiplatelet therapy. Comparative analysis between the two groups, on the variation of hemoglobin and hematocrit during the first and second postoperative days, was conducted to determine the amount of early postoperative bleeding and the frequency of allogenic blood transfusion during hospitalization. RESULTS: The variation of hemoglobin, hematocrit during the first and second postoperative days and the frequency of allogenic blood transfusion between no history of antiplatelet medication and discontinuation antiplatelet medication before 7 days from surgery were similar in both groups. Of the 369 patients, 149 patients received a blood transfusion during their hospitalization. Compared to patients who did not receive a blood transfusion, those who did received blood transfusion were significantly older in age, smaller in height, lighter in weight, and showed significantly lower preoperative hemoglobin and hematocrit values. No statistically significant differences in sex, preoperative American Society of Anesthesiologists scores, and the history of antiplatelet medication until 7 days prior to surgery were observed between the two groups according to blood transfusion. CONCLUSION: Compared to patients with no history of antiplatelet medication, the temporary discontinuation of antiplatelet medication 7 days prior to surgery in patients undergoing antiplatelet medication did not increase the amount of postoperative bleeding or the need for allogenic blood transfusion.

Clinical Utility and Cut-Off Scores of the Korean Adult Attention-Deficit/Hyperactivity Disorder Rating Scale

OBJECTIVES: This study was conducted to re-validate the clinical efficacy of the Korean Adult Attention-Deficit/Hyperactivity Disorder (ADHD) Rating Scale (K-AARS), which is a self-report scale for ADHD in adults, and to determine the clinical utility and cut-off scores of K-AARS. METHODS: The participants were 135 drug naïve adults with ADHD and 144 healthy controls. To diagnose ADHD based on the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition, two board-certified pediatric psychiatrists interviewed the participants and completed the Mini International Neuropsychiatric Interview. K-AARS was applied to all participants. K-AARS comprises six clinical subscales, one impairment subscale, and one driving behavior subscale. The receiver operating characteristic analysis was conducted to calculate the cut-off scores of K-AARS. RESULTS: All subscale scores, including six clinical subscale, impairment subscale, and driving behavior subscale scores, were found to be significant in distinguishing adults with ADHD from healthy controls. The sensitivity and specificity of the six clinical subscales were 63.0–77.0% and 66.7–79.9%, respectively. The combined total score of the six clinical subscales, had a sensitivity of 80.0% and specificity of 79.9%. CONCLUSION: The discriminative power of K-AARS for the diagnosis of ADHD in adults was excellent, and K-AARS and the empirical diagnosis of adults can be useful in diagnosing ADHD in adulthood.

Comparison of Attention-Deficit/Hyperactivity Disorder Practice in Adults According to a Training Background in Child Psychiatry

OBJECTIVES: Awareness of attention-deficit/hyperactivity disorder (ADHD) in adults has significantly increased; however, clinical data specific to the Korean population are insufficient. Clinical experience of ADHD may differ based on whether psychiatrists have received pediatric psychiatry-specific training. In order to prepare a practice parameter for adult ADHD patients in Korea, we examined questionnaire data to observe how pediatric psychiatry training could affect clinical practice for adults with ADHD. METHODS: A questionnaire about the diagnosis and treatment process was distributed to both general psychiatrists (GPsy) and child and adolescent psychiatrists (CAP) at the summer and winter workshop meetings of Korean Academy of Child and Adolescent Psychiatry. RESULTS: In total, 142 psychiatrists participated in the survey (86 GPsy, 56 CAP). GPsy and CAP preferred pharmacotherapy (GPsy 82.40%, CAP 64.30%) as the primary treatment option and answered that the clinical psychiatric interview is the most necessary step in diagnostic assessment (GPsy 22.16%, CAP 19.00%). The GPsy responded with an optimal and average treatment duration that was shorter than that reported by CAP. CONCLUSION: Identification of the initial presenting symptom as the correct diagnosis and the optimal duration of pharmacotherapy differed between GPsy and CAP in practice, whereas concepts in diagnosis and treatment of ADHD in adults were similar for both groups. These results suggest the urgent need for the Continuing Medical Education program for psychiatrists treating adults with ADHD.

Relationship between Lateral Femoral Bowing and Varus Knee Deformity Based on Two-Dimensional Assessment of Side-to-Side Differences

PURPOSE: The objective was to evaluate the relationship between side-to-side differences of lateral femoral bowing and varus knee deformity based on two-dimensional (2D) assessment in unilateral total knee arthroplasty (TKA). MATERIALS AND METHODS: A total of 143 patients with varus knee osteoarthritis who underwent unilateral TKA were enrolled. We evaluated the side-to-side differences of the frontal lower limb alignment by assessing lateral femoral bowing, anatomical medial distal femoral angle, and anatomical medial proximal tibial angle (aMPTA). RESULTS: The average values of all anatomical indices were significantly different between the operated side and the non-operated side (p < 0.05). The side-to-side difference in hip knee ankle (HKA) angle had a statistically significant correlation with that in lateral femoral bowing (intraclass correlation coefficient, 0.259; p=0.002) and that in aMPTA. Linear regression analysis showed 0.199° of side-to-side difference in lateral femoral bowing was associated with 1° of side-to-side difference in bilateral HKA angle. CONCLUSIONS: The side-to-side difference in lateral femoral bowing showed a tendency to increase in proportion to varus knee deformity based on 2D assessment in unilateral TKA patients.

Comparison of QEEG Findings between Adolescents with Attention Deficit Hyperactivity Disorder (ADHD) without Comorbidity and ADHD Comorbid with Internet Gaming Disorder

Internet gaming disorder (IGD) is often comorbid with attention deficit hyperactivity disorder (ADHD). In this study, we compared the neurobiological differences between ADHD comorbid with IGD (ADHD+IGD group) and ADHD without comorbidity (ADHD-only group) by analyzing quantitative electroencephalogram (QEEG) findings. We recruited 16 male ADHD+IGD, 15 male ADHD-only adolescent patients, and 15 male healthy controls (HC group). Participants were assessed using Young's Internet Addiction Scale and ADHD Rating Scale. Relative power and inter- and intra-hemispheric coherences of brain waves were measured using a digital electroencephalography (EEG) system. Compared to the ADHD-only group, the ADHD+IGD group showed lower relative delta power and greater relative beta power in temporal regions. The relative theta power in frontal regions were higher in ADHD-only group compared to HC group. Inter-hemispheric coherence values for the theta band between F3–F4 and C3–C4 electrodes were higher in ADHD-only group compared to HC group. Intra-hemispheric coherence values for the delta, theta, alpha, and beta bands between P4–O2 electrodes and intra-hemispheric coherence values for the theta band between Fz–Cz and T4–T6 electrodes were higher in ADHD+IGD group compared to ADHD-only group. Adolescents who show greater vulnerability to ADHD seem to continuously play Internet games to unconsciously enhance attentional ability. In turn, relative beta power in attention deficit in ADHD+IGD group may become similar to that in HC group. Repetitive activation of brain reward and working memory systems during continuous gaming may result in an increase in neuronal connectivity within the parieto-occipital and temporal regions for the ADHD+IGD group.

Comparison of Electroencephalography (EEG) Coherence between Major Depressive Disorder (MDD) without Comorbidity and MDD Comorbid with Internet Gaming Disorder

Internet gaming disorder (IGD) has many comorbid psychiatric problems including major depressive disorder (MDD). In the present study, we compared the neurobiological differences between MDD without comorbidity (MDD-only) and MDD comorbid with IGD (MDD+IGD) by analyzing the quantitative electroencephalogram (QEEG) findings. We recruited 14 male MDD+IGD (mean age, 20.0 ± 5.9 years) and 15 male MDD-only (mean age, 20.3 ± 5.5 years) patients. The electroencephalography (EEG) coherences were measured using a 21-channel digital EEG system and computed to assess synchrony in the frequency ranges of alpha (7.5–12.5 Hz) and beta (12.5–35.0 Hz) between the following 12 electrode site pairs: inter-hemispheric (Fp1–Fp2, F7–F8, T3–T4, and P3–P4) and intra-hemispheric (F7–T3, F8–T4, C3–P3, C4–P4, T5–O1, T6–O2, P3–O1, and P4–O2) pairs. Differences in inter- and intra-hemispheric coherence values for the frequency bands between groups were analyzed using the independent t-test. Inter-hemispheric coherence value for the alpha band between Fp1–Fp2 electrodes was significantly lower in MDD+IGD than MDD-only patients. Intra-hemispheric coherence value for the alpha band between P3–O1 electrodes was higher in MDD+IGD than MDD-only patients. Intra-hemispheric coherence values for the beta band between F8–T4, T6–O2, and P4–O2 electrodes were higher in MDD+IGD than MDD-only patients. There appears to be an association between decreased inter-hemispheric connectivity in the frontal region and vulnerability to attention problems in the MDD+IGD group. Increased intra-hemisphere connectivity in the fronto-temporo-parieto-occipital areas may result from excessive online gaming.

The Revised Korean Practice Parameter for the Treatment of Attention-Deficit Hyperactivity Disorder (II): Diagnosis and Assessment

Attention-deficit hyperactivity disorder (ADHD) is a highly prevalent, impairing, and comorbid disorder that persists into adulthood. ADHD should be diagnosed in the same manner as other common adult mental health disorders. The three most important components in the comprehensive evaluation of patients with ADHD are the clinical interview, medical examination, and completion and scoring of behavior rating scales. The diagnostic evaluation of ADHD should include questions about the symptoms, family history, prior evaluation and treatment of ADHD, as well as other problems including alcohol and drug use. Screening interviews or rating scales, as well as interviews, should be used. When it is feasible, clinicians may wish to supplement these components of the evaluation with the objective assessments of the ADHD symptoms, such as through psychological tests. These tests are not essential to reaching a diagnosis, however, or to treatment planning, but may yield further information about the presence and severity of cognitive impairments that could be associated with some cases of ADHD. As comorbidity is the rule rather than the exception, clinicians should carefully screen for comorbid disorders as part of a comprehensive assessment of ADHD. To receive a diagnosis of ADHD, the person must be experiencing significant distress or impairment in his or her daily functioning, and must not meet the criteria for other mental disorders which might better account for the observed symptoms, such as mental retardation, autism or other pervasive developmental disorders, mood disorders and anxiety disorders. This report aims to suggest practice guidelines for the assessment and diagnosis of children, adolescents and adults with ADHD in Korea.

Differences in Resting-state Quantitative Electroencephalography Patterns in Attention Deficit/Hyperactivity Disorder with or without Comorbid Symptoms

OBJECTIVE: The aim of the present study was to evaluate the role of comorbid psychiatric symptoms on quantitative electroencephalogram (QEEG) activities in boys with the attention deficit/hyperactivity disorder (ADHD). METHODS: All participants were male students in the second, third or fourth grade in elementary school. Therefore, there were no significant differences in age or sex. Participants with ADHD were assigned to one of three groups: pure ADHD (n=22), ADHD with depressive symptoms (n=11), or ADHD with problematic internet use (n=19). The Korean version of the Children’s Depression Inventory and the Korean Internet Addiction Self-scale were used to assess depressive symptoms and problematic internet use, respectively. Resting-state EEG during eyes closed was recorded, and the absolute power of five frequency bands was analyzed: delta (1–4 Hz), theta (4–8 Hz), alpha (8–12 Hz), beta (12–30 Hz), and gamma (30–50 Hz). RESULTS: The ADHD with problematic internet use group showed decreased absolute theta power at the central and posterior region compared with the pure ADHD group. However, The ADHD with depressive symptoms group showed no significant differences compared with the other groups. CONCLUSION: These findings will contribute to a better understanding of brain-based electrophysiological changes in children with ADHD in accordance with comorbid psychiatric symptoms.

Clinical Practice Guidelines for Major Comorbid Disorders with Attention-Deficit Hyperactivity Disorder / 신경정신의학

Attention-deficit hyperactivity disorder (ADHD) occurs with a high prevalence of comorbid disorders, and these comorbid disorders can affect assessment, clinical symptoms, prognosis, and treatment strategies for children with ADHD. The goal of this study was to develop a clinical practice guideline for ADHD and its specific comorbid disorders. Due to limited numbers of previous clinical studies, current recommendations are based on literature review and expert consensus among Korean child and adolescent psychiatrists. We suggest the use of multidisciplinary evaluations, interview techniques, and assessment tools in order to differentiate major comorbid disorders from ADHD. Specific ADHD comorbid disorders (e.g., medical comorbidity, oppositional defiant disorder, conduct disorder, bipolar disorder, major depressive disorder, anxiety disorder, specific learning disorder, tic disorder, and substance use disorder) have suggested treatment protocols that include pharmacological and behavioral treatments. Children and adolescents with ADHD may have comorbid disorders. The use of current clinical practice guidelines will be helpful when treating ADHD children with comorbid disorders.

Correlations among Social Anxiety, Self-Esteem, Impulsivity, and Game Genre in Patients with Problematic Online Game Playing

OBJECTIVE: Recent studies of online game addiction have suggested that social interaction and impulsivity are critical factors for the etiology and progress of online game addiction. We hypothesized that the genre of the online game is associated with impulsivity and sociality in individuals with online game addictions. METHODS: In total, 212 patients with problematic online game playing were divided into four groups by game genre: 1) massive multiplayer online role playing game (MMORPG), 2) real-time strategy (RTS), 3) first-person shooter (FPS), and 4) other. Their symptoms and characteristics were assessed using 8 scales and 2 tests to estimate self-esteem, impulsiveness, comorbidity, social interaction status, and cognitive function. RESULTS: The mean social anxiety score was highest in the MMORPG group and lowest in the FPS group. The mean self-esteem score was highest in the RTS group. Social anxiety score was positively correlated with Internet addiction score in the MMORPG group, and the self-esteem score was positively correlated with Internet addiction score in the RTS group. CONCLUSION: The genre of online game was not associated with impulsivity, but social anxiety status varied significantly with game genre, and differences in social anxiety were especially pronounced in patients playing the MMORPG (highest social anxiety) and FPS (lowest social anxiety) game genres. In addition, self-esteem was highest in the RTS game genre.

The Code of Medical Ethics for the Korean Academy of Child and Adolescent Psychiatry: Why Is It Important?

This article provides an overview of the developmental history and rationale of medical ethics to establish the code of ethics and professional conduct of the Korean Academy of Child and Adolescent Psychiatry (KACAP). Most medical professional organizations have their own codes of ethics and conduct because they have continuous responsibility to regulate professional activities and conducts for their members. The Ethics and Award Committee of the KACAP appointed a Task-Force to establish the code of ethics and conduct in 2012. Because bioethics has become global, the Ethics Task Force examined global standards. Global standards in medical ethics and professional conduct adopted by the World Medical Association and the World Psychiatric Association have provided the basic framework for our KACAP's code of ethics and professional conduct. The Code of Ethics of the Americal Academy of Child and Adolescent Psychiatry has provided us additional specific clarifications required for child and adolescent patients. The code of ethics and professional conduct of the KACAP will be helpful to us in ethical clinical practice and will ensure our competence in recognizing ethical violations.

Utilization of Western and Traditional Korean Medicine for Children and Adolescents with Mental Disorders: a Nationwide Population-based Study from 2010 to 2012

When in need of medical treatment, Korean citizens have a choice of practitioners of western medicine (WM) or Traditional Korean Medicine (TKM). However, the two branches frequently conflict with one another, particularly with regard to mental disorders. This study was designed to compare the utilization of WM and TKM, focusing on child/adolescent patients with mental disorders. We analyzed F-code (Mental and behavioral disorders) claims from the Korean Health Insurance Review and Assessment Service, including data from 0-18-year-old patients from 2010 to 2012. Slightly more men than women utilized WM, while TKM use was almost evenly balanced. WM claims increased with advancing age, whereas utilization of TKM was common for the 0-6 age group. In WM and TKM, the total number of claims relying on the National Health Insurance Service (NHIS) was 331,154 (92.78%) and 73,282 (97.85%), respectively, and the number of claims relying on medical aid was 25,753 (7.22%) and 1,610 (2.15%), respectively. The most frequent F-coded claim in WM was F90 (Hyperkinetic disorders), with 64,088 claims (17.96%), and that in TKM was F45 (Somatoform disorders), with 28,852 claims (38.52%). The prevalence of a single disorder without comorbidities was 168,764 (47.29%) in WM and 52,615 (70.25%) in TKM. From these data, we conclude that WM takes prevalence over TKM in cases of attention deficit/hyperactivity disorder (ADHD), as well as in psychological problems such as depression and anxiety. On the other hand, patients utilizing TKM more commonly present with physical health problems including somatoform problems, sleep, and eating disorders.

The Correlation between Clinical Symptoms, Serum Uric Acid Level and EEG in Patient with Bipolar I Disorder / 신경정신의학

OBJECTIVES: High uric acid level is related to increased locomotor activities and refractory mood swings. The purpose of this study is to examine the correlation between clinical symptoms of mania, serum uric acid level, and quantitative electroencephalography (QEEG) findings. METHODS: Twenty-four patients with bipolar disorder and 24 healthy control subjects agreed to participate in the study. When they were hospitalized, the degree of clinical symptoms, uric acid level in blood, and brain QEEG were measured. RESULTS: The bipolar disorder group showed higher scores on the Young Mania Rating Scale (YMRS ; z=6.02, p<0.05). Patients in their manic episodes showed higher plasma uric acid levels (4.9+/-1.3 mg/dL) than healthy control subjects (4.2+/-0.9 mg/dL ; z=2.14, p<0.05). Uric acid levels showed correlation with severity of manic symptoms as assessed using the YMRS in all participants (rho=0.28, p<0.05). The bipolar disorder group showed decreased relative delta and alpha activity in the fronto-temporo-occipital region compared to the control group (p<0.05). Relative beta in Fp1 (frontopolar), Cz (central mid-line), and Pz (parietal mid-line) and relative gamma in Fp1 were increased in the bipolar disorder group, relative to the control group (p<0.05). The relative beta (rho=0.47, p<0.05) and gamma (rho=0.41, p<0.05) in Fp1 electrodes showed positive correlation with the YMRS scores. CONCLUSION: Adenosinergic transmission dysfunction may lead to occurrence of manic symptoms, considering that a key role of central nervous system adenosinergic receptors is to inhibit the release of various neurotransmitters and limit neuronal excitability. In addition, QEEG appeared to indicate excitatory neuro-modulation in manic patients.

The Guideline of Diagnosis and Treatment of Attention-Deficit Hyperactivity Disorder: Developed by ADHD Translational Research Center

Attention-deficit hyperactivity disorder (ADHD) is one of the most common childhood psychiatric conditions. In 2007, the Korean Academy of child and Adolescent Psychiatry developed Korean ADHD practice parameter. Advances in the scientific evidence of ADHD caused practice parameter to be modified and updated. The present guidelines developed by ADHD translational research center summarize current literature for the treatment of ADHD in children and adults. This parameter includes the clinical evaluation for ADHD, comorbid conditions associated with ADHD, clinical feature and course, research on the etiology of the disorder, and psychopharmacological and non-pharmacological treatments for ADHD.

Internet Gaming Disorder Treatment Options in the Hospital Setting

Internet gaming disorder (IGD), one of the common subtypes of internet addiction, is now classified in Section 3 of DSM-5 and is increasingly regarded as a growing health concern in many parts of the world. Consequently, many psychotherapeutic and psychopharmacological approaches have been considered and some research regarding therapeutic strategies has been conducted. However, treatment of IGD is in its early stages and therefore is not yet well established. This article reviews multiple therapeutic modalities including our own treatment model for IGD according to clinical and biological effects, thus providing suggestions for standard treatment strategies. The two main streams are psychopharmacological treatment and cognitive-behavior treatment, and the cognitive-behavior approach includes cognitive reconstruction, psychoeducation, and parenting coach. Many other non-pharmacological treatments are also recommended for personalized treatment of IGD.
