Do we need neuroimaging to treat insomnia effectively?

In recent years, the diagnosis of insomnia disorder has shown striking developments concerning its conceptualization, assessment and treatment. Notably, the main comprehensive models on insomnia have been behavioral or psychological [1]. These theoretical conceptualizations led to numerous intervention techniques, which continued to be used over the years [2,3]. Several studies such as randomized controlled trials (RCT) and meta-analyses have reinforced the efficacy and efficiency of cognitive-behavioral therapies for insomnia (CBT-I) [3].
