Trends in insomnia research for the next decade: a narrative review

Insomnia disorder has known striking developments over the last few years. Partly due to advances in neuroimaging techniques and brain sciences, our understanding of insomnia disorder has become more fine-tuned. Besides, developments within psychological and psychiatric fields have contributed to improve conceptualization, assessment, and treatment of insomnia. In this paper, we present a list of promising 10 key “hot-topics” that we think in the next 10 years will continue to stimulate researchers in insomnia’s domain: increasing of systematic reviews and meta-analyses; improvement of existing self-report measures; increasing of genetic and epigenetic investigation; research on new pharmacological agents; advances in neuroimaging studies and methods; new psychological clinical approaches; effectiveness studies of e-treatments and greater dissemination of evidence-based therapies for insomnia; call for integrative models; network approach using in insomnia; and assessment of insomnia phenotypes. The breadth of all these topics demands the collaboration of researchers from different scientific fields within sleep medicine. In summarizing, in the next decade, it is predictable that insomnia’s research still benefit from different scientific disciplines.
