Research progress on cognitive function and neural mechanisms of non-suicidal self-injury in adolescents
摘要
The prevalence of non-suicidal self-injury (NSSI) among adolescents is on the rise worldwide, and an increasing number of studies indicate that the onset age tends to be younger. Therefore, it has become a public health issue of great concern to all sectors of society.Contrary to previous research perspectives, current studies suggest that NSSI behaviors can be present in various disorders, such as mood disorders, personality disorders, and substance use disorders.Research shows that individuals engaging in NSSI often have impaired social functioning, which is closely related to impaired cognitive function.Impairments in different components also suggest corresponding functional deficits. Cognitive function encompasses numerous components, mainly including attention, executive function, and learning and memory. These components are associated with the occurrence and development of NSSI to some extent.It is worth noting that the identification and assessment of NSSI behaviors have gone beyond the traditional scope of neuropsychology.In neuroimaging and neurophysiology, an increasing number of research results suggest that there are significant differences in brain function and structure between individuals with NSSI and healthy individuals. Therefore, this article systematically reviews the literature on the cognitive functional characteristics and neural mechanisms of adolescents with NSSI behaviors, aiming to provide a basis for a deeper understanding of the neurobiological basis of NSSI.
