Proposed pathways include: Delta wave promotion -- DSIP was named for its ability to increase delta wave activity (0.5-4 Hz EEG frequencies) in animal models, the characteristic brainwave pattern of deep slow-wave sleep Stress hormone modulation -- some studies report normalization of cortisol and ACTH rhythms, which could create more favorable conditions for sleep onset and GH release Endorphin system interaction -- DSIP has been reported to interact with opioid systems, potentially contributing to its analgesic and sleep-modulating properties LH and GH modulation -- DSIP may influence the release of luteinizing hormone and growth hormone, linking it to broader endocrine regulation during sleep Clinical Evidence# Human studies on DSIP span several decades but present a mixed picture: A 1986 study by Schneider-Helmert and Schoenenberger investigated DSIP in chronic insomnia patients and reported improvements in sleep onset and sleep efficiency in a subset of subjects Studies in narcolepsy patients showed some effects on sleep organization, though results were inconsistent Research in healthy volunteers has produced variable results, with some studies showing increased slow-wave sleep and others finding no significant effect Several studies reported improvements in subjective sleep quality, even when objective polysomnographic measures did not consistently change Limitations# DSIP research faces significant challenges

TNF--induced increase in intestinal epithelial tight junction permeability requires NF-B activation

Unlike other types, it requires more aggressive treatment such as prescription medications and sometimes corticosteroid injections
