Nataliya Titova, K Ray Chaudhuri
Nonmotor symptoms (NMS) of Parkinson's disease (PD) are integral to the condition largely regarded as a motor syndrome. A range of NMS underpin the prodromal stage of Parkinson's and are present with variable frequency, range, and nature across the whole journey of a patient with Parkinson's from the onset of the motor disease to palliative stage. These symptoms also are key determinants of quality of life of the patient as well as the carer. Despite this, recognition management and focused treatment of NMS of PD remain poor...

Nonmotor symptoms of Parkinson's disease (PD) range from neuropsychiatric, cognitive to sleep and sensory disorders and can arise from the disease process as well as from drug treatment. The clinical heterogeneity of nonmotor symptoms of PD is underpinned by a wide range of neuropathological and molecular pathology, affecting almost the entire range of neurotransmitters present in brain and the periphery. Understanding the neurobiology and pathology of nonmotor symptoms is crucial to the effective treatment of PD and currently a key unmet need...

Although only a minority (i.e., ~5%) of Parkinson's disease (PD) cases is due to well-defined genetic causes, important clues about the common, "idiopathic" PD (iPD) can be garnered from monogenic model diseases. Nonmotor signs (NMS) are also present in monogenic PD and reviewed in this chapter for the confirmed PD genes SNCA, LRRK2, VPS35, Parkin, PINK1, DJ-1, and the risk factor gene GBA. Within the context of the MDSGene database (www.mdsgene.org), we performed a systematic literature search and extracted information on cognitive decline, depression, psychotic signs and symptoms, autonomic signs and symptoms, anxiety, sleep disorder, and olfactory impairment...

Fluctuations in brain water content has attracted increasing interest, particularly as regards studies of the glymphatic system, which is connected with the complex organisation of dural lymphatic vessels, responsible for cleaning tissue. Disturbances of glymphatic circulation are associated with several brain disorders, including dementia. This paper introduces an approach to non-invasive measurement of water dynamics in the human brain utilizing near-infrared spectroscopy (NIRS). We demonstrate the possibility to sense dynamic variations of water content between the skull and grey matter, for instance, in the subarachnoid space...

Recent studies have demonstrated the presence of oxidative stress in insomnia patients. Uric acid (UA) is regarded as one of the most important antioxidants that may attenuate oxidative stress. The aim of our study was to investigate whether there is an alteration of serum UA levels in chronic insomnia patients. The association between sleep quality and serum UA in chronic insomnia patients was also investigated. We recruited 300 chronic insomnia patients and 300 age- and gender-matched normal controls. The uricase-PAP method was used to measure the concentration of UA both in patient and normal control subjects...

OBJECTIVES: Small for gestational age infants have an increased risk of immediate complications, short-term morbidity and mortality, and long-term neurologic and metabolic disorders in adulthood. Previous research has shown that reduced sleep duration is a risk factor for SGA birth. However, only a few studies have evaluated maternal sleep as a risk factor for SGA birth. In the present study, we investigated the relationship between the amount and quality of mothers' sleep and infants' birth weight...

Activation of oxytocin receptors has shown benefits in animal models of Obstructive Sleep Apnea (OSA). We tested if nocturnal oxytocin administration could have beneficial effects in OSA patients. 8 patients diagnosed with OSA were administered intranasal oxytocin (40 i.u.). Changes in cardiorespiratory events during sleep, including apnea and hypopnea durations and frequency, risk of event-associated arousals, and heart rate variability were assessed. Oxytocin significantly increased indices of parasympathetic activity, including heart rate variability, total sleep time, and the Post-Polysommogram Sleep Assessment (PPSA) score, an index of self-reported sleep satisfaction...

The brain is a vital organ that relies on a constant and adequate blood flow to match oxygen and glucose delivery with the local metabolic demands of active neurons. Thus, exquisite regulation of cerebral blood flow (CBF) is particularly important under hypoxic conditions to prevent a detrimental decrease in the partial pressure of oxygen within the brain tissues. Cerebrovascular sensitivity to hypoxia, assessed as the change in CBF during a hypoxic challenge, represents the capacity of cerebral vessels to respond to, and compensate for, a reduced oxygen supply, and has been shown to be impaired or blunted in a number of conditions...

BACKGROUND: Previous research has identified that men experiencing depression do not always access appropriate health services. Web-based interventions represent an alternative treatment option for men, are effective in reducing anxiety and depression, and have potential for wide dissemination. However, men do not access Web-based programs at the same rate as women. Programs with content explicitly tailored to men's mental health needs are required. OBJECTIVE: This study evaluated the applicability of Man Central, a new Web and mobile phone intervention for men with depression...

Leptin is a peptide hormone mainly produced in white adipose tissue. It is known to regulate energy homeostasis, inflammation, metabolism, and sympathetic nerve activity. Increasing evidence suggests it has a role in ventilatory function and upper airway obstruction. Leptin levels correlate positively with measurements of adiposity and can potentially provide important insights into the pathophysiology of diseases associated with obesity. Obesity is a strong risk factor for obstructive sleep apnea, a disease characterized by periodic upper airway occlusion during sleep...

Obstructive sleep apnea (OSA) is prevalent in obese subjects. Plasma adiponectin level in obese subjects is decreased. Whether reduced adiponectin level is associated with OSA is unknown. Participants without a previous diagnosis of OSA or who have not been treated with continuous positive airway pressure were enrolled and parameters of interest were collected. Polysomnography was performed to evaluate the presence of OSA and the severity of OSA as indexed by the apnea-hypopnea index (AHI). Between-group differences were analyzed...

Leptocarpus disjunctus Mast. (Restionaceae) is an edible plant which has indigenous warnings regarding its side effects which can manifest as dizziness. This study investigated hypnotic and anxiolytic properties using several animal models. Anxiolytic activities were evaluated using locomotor determination by elevated plus-maze test, open-field test, and rotarod performance test. Hypnotic activities were performed using pentobarbital sodium-induced sleeping time test. Sleep architecture and quality were obtained from sleep-wake analysis and nonrapid eye movement (NREM) delta activity using electroencephalography...

Retinoic acid induced 1 ( RAI1 ) encodes a dosage-sensitive gene that when haploinsufficient results in Smith-Magenis syndrome (SMS) and when overexpressed results in Potocki-Lupski syndrome (PTLS). Phenotypic and molecular evidence illustrates that haploinsufficiency of RAI1 disrupts circadian rhythm through the dysregulation of the master circadian regulator, circadian locomotor output cycles kaput ( CLOCK) , and other core circadian components, contributing to prominent sleep disturbances in SMS. However, the phenotypic and molecular characterization of sleep features in PTLS has not been elucidated...

We examined the factors associated with the evaluation of health description vignettes and how Japanese people make decisions related to the eight health dimensions (mobility, emotions, pain, relationship with others, sleep and energy, vision, recognition/remembering abilities, and self-care). We investigated a dataset of 4,959 respondents (≥ 18 years) from the Japanese World Health Survey. Ordered probit models were used to identify factors associated with all health dimensions. On all dimensions, older people appraised extreme problems as less problematic than young people did...

Genetic variants in CACNA1C (calcium voltage-gated channel subunit alpha1 C) are associated with bipolar disorder and schizophrenia where sleep disturbances are common. In an experimental model, Cacna1c has been found to modulate the electrophysiological architecture of sleep. There are strong genetic influences for consolidation of sleep in infancy, but only a few studies have thus far researched the genetic factors underlying the process. We hypothesized that genetic variants in CACNA1C affect the regulation of sleep in early development...

Although insomnia has been repeatedly linked with suicide ideation, the reason for the linkage is not clear. The Interpersonal Psychological Theory of Suicide (IPTS) proposes that three core variables (thwarted belongingness, perceived burdensomeness, and acquired capability) are the final common pathway for all risk factors for suicide ideation and behavior. Recent research has suggested that insomnia may be associated with suicide ideation independently of the IPTS. We examined cross-sectional data from 151 psychiatric inpatients (ages 12-17) to determine if the association between insomnia symptoms and a continuous measure of suicide risk (measured as increasingly severe ideation and plan) was explained by the framework of the IPTS...
