Purpose of Review
Besides gaming disorder, which has recently been included in the ICD-11, several other types of Internet-use behaviors were shown to have addictive potential causing impairments in daily life. Research on Internet-communication disorder (ICD) focuses on the pathological use of Internet-communication applications. However, its clinical relevance as well as similarities to other addictive behaviors have to be clarified.
Recent neuropsychological studies try to identify relevant neural mechanisms underlying ICD. Summarizing the results of brain imaging studies indicate the relevance of brain areas associated with reward processing and reinforcement learning in the context of ICD. The findings are consistent with theoretical assumptions and empirical findings on other addictive behaviors.
The current review highlights similarities between different kinds of Internet-use disorders. Regarding ICD, evidence is still rare and relevant standards are missing. Further studies, especially with treatment seekers, are needed to clarify the clinical relevance and to identify convergent and divergent components of general and specific (Internet-related) addictive behaviors.

Instead, the authors provide directions for future research in the field of behavioral addictions by highlighting the need for an approach that focuses on the psychological processes involved.
