The review is devoted to the complex relationship between headache and sleep disorders. The shared neuroanatomical structures of the nervous system involved in pain perception and sleep are shown, and mechanisms of comorbidity between headaches and sleep disorders are considered. Various types of headaches in the continuum of the sleep–wake cycle are described. Both pharmacological and non-pharmacological approaches to treatment are examined in detail, with the biochemical basis of the drug action.
Objective In this narrative review, we summarize clinical and experimental data on the effect of light in migraine and discuss future prospects. Background Effective nonpharmacological treatment of hypersensitivity to light in migraine is an unmet clinical need. Current management strategies primarily consist of seeking a dark room and avoiding light exposure. Advances in the past 2 decades have improved our understanding of the underlying pathophysiology of how migraine is influenced by light. This may provide promising avenues for novel approaches in clinical management. Methods We searched MEDLINE for articles published from database inception up to September 1, 2021. We used the search term “migraine” with the search terms “light,” “photophobia,” “treatment,” “trigger,” “circadian rhythm,” “environment,” and/or “pathophysiology.” Results Light is commonly reported as a trigger factor of migraine attacks, however, early manifestation of photophobia and false attribution is likely the actual cause based on data deriving from retrospective, prospective, and experimental studies. The most common photophobia symptoms in migraine are exacerbation of headache by light and abnormal sensitivity to light with the underlying neural pathways likely being dependent on ongoing activity in the trigeminovascular system. Clinical studies and experimental models have identified mediators of photophobia and uncovered narrow wavebands of the light spectrum that may reduce pain intensity during a migraine attack. Consequently, novel devices have undergone exploratory clinical trials with promising results. Conclusion False attribution is likely the reason why light is commonly reported as a trigger factor of migraine attacks, and a prospective confirmation is required to prevent unnecessary avoidance. The observation that individuals with migraine are not equally photophobic to all wavebands of the light spectrum opens the potential for innovative pain management strategies. In this context, using human‐centric lighting (also called integrative lighting) to mimic the natural daylight cycle and avoid harmful wavebands through modern technology may prove beneficial. Future research should identify direct and indirect consequences of light and other environmental factors in migraine to fill out knowledge gaps and enable evidence‐based care strategies within institutions, work environments, and other settings.
Background. There are still no clearly proven methods to slow down or stop the progression of Parkinson’s disease (PD). Thus, improving the quality of life (QoL) of patients with PD becomes of primary importance. Autonomic dysfunction and its symptoms are known to worsen the quality of life in PD, but the degree of this influence is underinvestigated. Particularly, impacts of the separate significant gastrointestinal symptoms, such as dyspepsia, constipation, and abdominal pain, in PD should be more precisely evaluated with the help of specific scales. Objective. To assess the impacts of gastrointestinal dysfunction and its symptoms on PD patient’s QoL using PDQ-39. Methods. 111 PD patients in the I-III Hoehn and Yahr (H&Y) stage were enrolled in the study. The following scales were applied: UPDRS III, PDQ-39, GSRS, GDSS, MMSE, BDI, STAI-S, and STAI-T. Results. The linear regression model showed that the PDQ-39 SI depended on summary assessments GSRS-SI (β = 0.333, p < 0.001 ), BDI (β = 0.463, p < 0.001 ), and UPDRS III (β = 0.163, p < 0.05 ). The use of the stepwise method, adding GSRS-SI and UPDRS III scores to the BDI predictor, improved the model (R2 increased from 0.454 to 0.574). The investigation of GSRS domain’s influence revealed that PDQ-39 SI had a significant correlation with almost all of them, but the regression analysis showed significant QoL impacts of only two factors: constipation and abdominal pain (β = 0.288, p < 0.01 and β = 0.243, p < 0.05 accordingly). Conclusions. Our results suggest a considerable negative influence of depression and gastrointestinal dysfunction (especially constipation and abdominal pain) on QoL of patients with PD. Their impact on QoL in patients with I-III H&Y stages of PD is more significant than that of motor symptoms. Therefore, the correction of depression and gastrointestinal dysfunction should be prioritized in PD therapy.
The term neuronutrition has been proposed as part of nutritional neuroscience, studying the effects of various dietary components on behavior and cognition. Other researchers underline that neuronutrition includes the use of various nutrients and diets to prevent and treat neurological disorders. The aim of this narrative review was to explore the current understanding of the term neuronutrition as the key concept for brain health, its potential molecular targets, and perspectives of its nutritional approach to the prevention and treatment of Alzheimer’s and Parkinson’s diseases, multiple sclerosis, anxiety, depressive disorders, migraine, and chronic pain. Neuronutrition can be defined as a part of neuroscience that studies the influence of various aspects of nutrition (nutrients, diet, eating behavior, food environment, etc.) on the development of nervous disorders and includes nutrition, clinical dietetics, and neurology. There is evidence that the neuronutritional approach can influence neuroepigenetic modifications, immunological regulation, metabolic control, and behavioral patterns. The main molecular targets in neuronutrition include neuroinflammation, oxidative/nitrosative stress and mitochondrial dysfunction, gut–brain axis disturbance, and neurotransmitter imbalance. To effectively apply neuronutrition for maintaining brain health, a personalized approach is needed, which includes the adaptation of the scientific findings to the genetic, biochemical, psycho-physiological, and environmental features of each individual.
Chylothorax in children is a fairly rare but at the same time serious pathology. Accumulation of a large amount of fluid in the pleural cavity leads to the development of respiratory, cardiovascular failure, and even death. In some children, this process can be initiated even before birth. The main components in the treatment of chylothorax are as follows: conservative measures aimed at reducing the amount of chyle, paracentesis, and drainage of the pleural cavity, mini-invasive surgery. To date, universal approaches to the management of patients with chylothorax have not been fully developed, there are no common diagnostic algorithms, terms, and optimal treatment tactics. There are only a few publications on this issue in literature, which are descriptive in nature and based on a small number of observations. The low prevalence of chylothorax in newborn infants, different etiology, various pathogenetic mechanisms of the disease make it difficult to conduct large-scale randomized trials in this area that would fully meet the modern requirements of evidence-based medicine. In this article, the authors demonstrate a multidisciplinary approach to treating a child with congenital chylothorax.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
