The Brain-Derived Neurotrophic Factor: Missing Link Between Sleep Deprivation, Insomnia, and Depression.

The Brain-Derived Neurotrophic Factor: Missing Link Between Sleep Deprivation, Insomnia, and Depression. Neurochem Res. 2019 Nov 28;: Authors: Rahmani M, Rahmani F, Rezaei N Abstract The brain-derived neurotrophic factor (BDNF) mediates the plasticity-related changes that associate with memory processing during sleep. Sleep deprivation and chronic stress are associated with propensity to depression, anxiety, and insomnia. We propose a model by which explain alterations in the CNS and serum expression of BDNF associated with chronic sleep deprivation, depression, and insomnia. Mild sleep deprivation activates the cerebral cortex and brainstem to generate the physiologic drive for non-rapid eye movement (NREM) and rapid eye movement (REM) sleep drive respectively, associated with BDNF upregulation in these regions. This physiological response loses effectiveness with longer episodes or during chronic of total or selective REM sleep loss, which are associated with impaired hippocampal BDNF expression, impaired memory and cognition. Chronic sleep deprivation and insomnia can act as an external stressors and result in depression, characterized by hippocampal BDNF downregulation along with disrupted frontal cortical BDNF expression, as well as reduced levels and impaired diurnal alterations in serum BDNF expression. Acute REM sleep deprivation breaks the cycle by restoration of hippocampal, and possibly restoration of cortical and serum expression of BDNF. The...

AbstractPurpose of ReviewThe purpose of this review article is to provide an overview of sleep and pulmonary comorbidities in patients with psoriasis and summarize important recent findings.Recent FindingsEvidence continues to show that patients with psoriasis experience greater chronic sleep impairment when compared to healthy counterparts. In addition to other comorbidities seen in psoriasis patients, including cardiovascular disease, obesity, and diabetes, obstructive sleep apnea and chronic obstructive pulmonary disease have increased frequency in this population.SummarySleep and pulmonary comorbidities in psoriasis co...

n Restless legs syndrome is a relatively common neurologic disorder considerably more prevalent in women than in men. It is characterized by an inactivity-induced, mostly nocturnal, uncomfortable sensation in the legs and an urge to move them to make the disagreeable sensation disappear. Some known genes contribute to this disorder and the same genes contribute to an overlapping condition—periodic leg movements that occur during sleep and result in insomnia. Dopamine and glutamate transmission in the central nervous system are involved in the pathophysiology, and an iron deficiency has been shown in region-sp...

Abstract STUDY OBJECTIVES: Positive airway pressure (PAP) noncompliance remains a major barrier in obstructive sleep apnea (OSA) treatment. The PAP-NAP, a daytime PAP "test-drive," has been associated with increased PAP use, but risk factors and indications for the procedure remain unspecified. METHODS: A retrospective chart review was conducted on 139 patients who (1) were diagnosed with OSA (n = 116) or upper airway resistance syndrome (UARS) (n = 23); (2) adamantly refused to proceed with either a full-night attended titration or in-home trial of PAP; and (3) elected to proceed with a PAP-NAP ins...

DiscussionThis is the first trial testing the effectiveness of smartphone apps delivered to school students to prevent depression at scale. Results from this trial will provide much-needed insight into the feasibility of this approach. They stand to inform policy and commission decisions concerning if and how such programmes should be deployed in school-based settings in Australia and beyond.Trial registrationAustralian and New Zealand Clinical Trial Registry,ACTRN12619000855123.

What are the Signs of Opioid Use? Opioids are a group of drugs derived naturally from the poppy plant, or are man-made in a laboratory, also known as synthetic opioids. Opioids are generally prescribed to individuals suffering from chronic pain, whether from surgery, a major injury or other health issues. Legally prescribed opioids include morphine, codeine, and oxycodone, while illegal opioids include heroin. It is easy to know if an individual is using opioids if they’ve been prescribed, but it is also important to know the signs of opioid use if it has crossed the line into an addiction. Signs and Symptoms There a...

Conclusions: Our data are in accordance with previous findings outlining that N + insomniacs have higher PSQI scores than N-. Our results do not confirm the suggested association between napping and depressive or obsessive-compulsive symptoms. Conversely, we found a statistically significant difference (p = 0.0014) in EAT scores in N + and N-. Hyperarousal and REM sleep instability in insomniac patients may create an unbalance of the neuroendocrine hypothalamic regulation leading to an appetite alteration.

Conclusions: The present eCBT-I program seems feasible, acceptable and effective in reducing insomnia severity and insomnia-related functional outcomes in this small clinically-derived population. Given the high prevalence of insomnia, our data are supportive of the use of such program as an effective alternative to treat insomnia in daily clinical practice in French speaking countries.

Conclusions: Insomnia symptoms and obesity were related to overall aggressive behavior in PWE independent of depressive symptoms. The individual subscales of the AQ were correlated differently with the various factors including male sex, obesity, depressive symptoms, anxiety, insomnia symptoms, epilepsy severity, polytherapy, and the use of perampanel.
