Shopping is, and has long been, an important part of everyday life. It can easily take on the characteristics and symptoms of a behavioral addiction, such as preoccupation, mental appropriation as well as compulsiveness and loss of control. Thus, shopping addiction is becoming an increasingly important topic in research, especially in the context of the current pandemic . The pandemic has resulted in an increase in perceived risk factors. There is a plausible relationship between high perceived stress level along with perceived social isolation and extensive leisure time in shifting toward a pathological shopping behavior. While that does not only have a negative impact on functional but also on social and financial aspects, findings suggest that the threshold is also becoming lower due to changing social values, including changing self-conception and progressing digitalization that make online shopping more accessible. Although different reasons for an increasing prevalence rate are being discussed, the diagnosis conceptualization and classification is still unclear, leading to different and unstandardized therapeutic approaches. In addition to its impact on daily life, shopping addiction can indicate other mental illnesses. As it turned out, it is often comorbid in anxiety disorders, impulsive behaviors and substance abuse. An early and targeted treatment, as well as rising awareness, seem to be crucial and call for further investigation. While young people seem to be more at risk of developing critical shopping behavior, findings show no clear gender differences in frequency but differences in terms of buying motivation. Based on published research papers, the present narrative review therefore describes and critically discusses the phenomenon of shopping addiction and the current state of research in a broad variety of topics, considering types of shopping behavior, including Internet-based, offline, mood, impulse and leisure shopping, and diagnostic and therapeutic options in the context of influencing factors mentioned above. The

Background: Online or internet gaming disorder (IGD) is currently not recognized as a mental disorder in the actual Diagnostic and Statistical Manual of Mental Disorders (DSM-5), although it is an emerging disease. Non-substance-related addictions often have similarities with substance addictions. It is therefore important to have a good understanding of the client but also to have a good endurance. Due to the rise of e-sports, there is an anticipated and therefore possible trend to have many more patients with a non-substance addiction. There are many parallels, for instance tolerance, withdrawal and social problems, resulting from an increasing investment of time spent on the internet. Case presentation: To reduce possible inhibition in treating a patient with IGD, we present a case of a 19-year-old adolescent man who exhibited IGD and showed social problems associated with his addiction. Conclusions: This paper shows the importance and the effects of treating a non-substance addiction with cognitive behavioral therapy (CBT). After having successfully coped with an addiction, several shifts in addiction were often reported. In this case, no shifts were reported. The absence of such shifts makes our case a distinct and unique case. This is not a multimorbidity case, and that is the reason why we think this is an excellent example to show what we achieved, how we achieved it, and what we could establish. Of course, additional research and manuals are urgently needed.
