Abstract

STUDY OBJECTIVES: Frequently disrupted and restricted sleep is a common problem for many people in our Western society. In the long run, insufficient sleep may have repercussions for health and may sensitize individuals to psychiatric diseases. In this context, we applied an animal model of chronic sleep restriction to study effects of sleep loss on neurobiological and neuroendocrine systems that have been implied in the pathophysiology of depression, particularly the serotonergic system and the hypothalamic-pituitary-adrenal (HPA) axis. DESIGN: Adult rats were exposed to a schedule of chronic partial sleep deprivation allowing them only 4 h of sleep per day. Sleep restriction was achieved by placing the animals in slowly rotating drums. To examine the regulation and reactivity of the HPA axis, blood samples were collected to measure adrenocorticotropin (ACTH) and corticosterone (CORT) responses. MEASUREMENTS AND RESULTS: While one day of restricted sleep had no significant effect on HPA axis stress reactivity, sleep restriction for a week caused a blunted pituitary ACTH response in a conditioned fear paradigm. Despite this lower ACTH response, adrenal CORT release was normal. The blunted pituitary response may be related to reduced sensitivity of serotonin-1A receptors and/or receptors for corticotropin-releasing hormone (CRH), since sleep restricted rats showed similar reductions in ACTH release to direct pharmacological stimulation with a serotonin-1A agonist or CRH. CONCLUSIONS: Chronic sleep restriction may lead to changes in neurotransmitter receptor systems and neuroendocrine reactivity in a manner similar to that seen in depression. This experimental study thus supports the hypothesis that disrupted and restricted sleep may contribute to the symptomatology of psychiatric disorders.

  • Animal studies point towards a direct stimulatory effect of sleep loss on the HPA axis.

    “Animal studies, however, have pointed towards a direct stimulatory effect of sleep loss on the HPA axis.[23][24][25]”

    From Effects of Insufficient Sleep on Pituitary–Adrenocortical Response to CRH Stimulation in Healthy Men (2017) · cites this paper as [25]

    The Abstract reports that one day of restricted sleep had no significant effect on HPA-axis stress reactivity, while a week of restriction blunted the pituitary ACTH response. The Discussion likewise reports reduced ACTH responses and unchanged or mildly reduced corticosterone responses, rather than a direct stimulatory effect. (LLM, conf=0.90)

    Checked by a reasoning model — may be wrong.

    Experimental — accuracy not yet measured
  • Studies in rodents have demonstrated that recurrent sleep restriction affects spontaneous pituitary-adrenal activity and the response to CRH and to experimental stressors.

    “Studies in rodents have demonstrated that recurrent sleep restriction affects not only spontaneous pituitary-adrenal activity but also the response to corticotropin-releasing hormone (CRH) 25 and to experimental stressors.[23][24][25]”

    From Effects of Insufficient Sleep on Pituitary–Adrenocortical Response to CRH Stimulation in Healthy Men (2017) · cites this paper as [25]

    The Results (CRH Challenge) report a reduced ACTH response to injected CRH in sleep-restricted rats, and the Results and Discussion report a blunted ACTH response to conditioned fear. These passages support the claims about responses to CRH and experimental stressors, but our copy does not establish an effect on spontaneous pituitary-adrenal activity. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • A study in rats reported a blunted ACTH response to CRH injection after recurrent partial sleep loss.

    “Our results are in line with a study in rats that reported a blunted ACTH response to CRH injection after recurrent partial sleep loss.25”
  • Sleep loss can affect neural systems involved in mood and behavior as well as in the regulation of circadian rhythms.

    “they suggest that sleep loss can affect neural systems involved in mood and behavior as well as in the regulation of circadian rhythms (Novati et al., 2008).”
  • In rodents, chronic sleep restriction results in decreased sensitivity of 5HT1A receptors.

    “In rodents, chronic sleep restriction results in decreased sensitivity of 5HT1A receptors, and although these experiments were conducted in adult animals, they suggest that sleep loss can affect neural systems involved in mood and behavior as well as in the regulation of circadian rhythms (Novati et al., 2008).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
