The pathogenesis, diagnosis and treatment of paradoxical insomnia / 中华行为医学与脑科学杂志

Paradoxical insomnia is a common clinical phenomenon.Due to the lack of comprehensive understanding of its pathogenesis, there were wide variability in diagnostic criteria and treatment outcomes, thus interfering with the correct statistics of its epidemiological data.Through the summary of previous studies, combination with our own research on the pathogenesis of chronic insomnia, we propose that the differences in the subjective and objective assessment of paradoxical insomnia are related to the asynchronous inactivation of the thalamus and cortex during the sleep initiation phase and the cortical activation sequence and intensity disorders in each region after sleep.Furthermore, the diagnosis of paradoxical insomnia and clinical characteristics are described according to the related pathogenesis and a targeted treatment strategy is formulated.Paradoxical insomnia is a type of insomnia with specific pathophysiological mechanism.
