Neuroimaging of Sleep and Depression

The document from December 19, 2017, explores the bidirectional relationship between sleep and skin health, noting that dermatologic conditions can cause sleep disturbances, while lack of sleep can worsen skin issues. It cites studies showing a higher prevalence of skin diseases in patients with sleep disorders, such as the Danish National Patient Registry study involving 19,438 patients with obstructive sleep apnea (OSA) and 755 with obesity hypoventilation syndrome (OHS), and another study with 2,998 children with OSA. The paper also discusses how certain dermatological treatments can impact sleep, with biologics potentially improving sleep-related complaints and CPAP masks sometimes causing skin problems like contact dermatitis. The authors stress the need for objective sleep measures in research. Additionally, the document reviews the impact of sleep disturbances on chronic idiopathic urticaria (CIU), with one study of 75 CIU patients linking insomnia to CIU, and another study of 24 patients finding no significant difference in sleep disturbance improvement between high-dose non-sedating antihistamines and a combination with sedating antihistamines. The document highlights a gap in research, as no polysomnography studies on urticaria were found, and most urticaria treatment trials do not focus on sleep outcomes.
