Abstract
Atypical parkinsonism (AP) comprises mainly multiple system atrophy (MSA), progressive supranuclear palsy (PSP), and corticobasal degeneration (CBD), which are distinct pathological entities, presenting with a wide phenotypic spectrum. The classic syndromes are now called MSA-parkinsonism (MSA-P), MSA-cerebellar type (MSA-C), Richardson's syndrome, and corticobasal syndrome. Nonmotor features in AP have been recognized almost since the initial description of these disorders; however, research has been limited. Autonomic dysfunction is the most prominent nonmotor feature of MSA, but also gastrointestinal symptoms, sleep dysfunction, and pain, can be a feature. In PSP and CBD, the most prominent nonmotor symptoms comprise those deriving from the cognitive/neuropsychiatric domain. Apart from assisting the clinician in the differential diagnosis with Parkinson's disease, nonmotor features in AP have a big impact on quality of life and prognosis of AP and their treatment poses a major challenge for clinicians.

Abstract
PURPOSE OF REVIEW Neurointestinal diseases are increasingly recognized as causes of significant gastrointestinal morbidity in children. This review highlights the most common pediatric enteric neuropathies and their diagnosis and management, emphasizing insights and discoveries from the most recent literature available. RECENT FINDINGS The embryologic and histopathologic causes of enteric neuropathies are varied. They range from congenital aganglionosis in Hirschsprung disease, to autoimmune-mediated loss of neuronal subtypes in esophageal achalasia and Chagas disease, to degenerative neuropathies in some cases of chronic intestinal pseudo-obstruction and gastroparesis. Increased awareness of the clinical presentation and diagnostic evaluation of these conditions is essential as it allows for earlier initiation of treatment and improved outcomes. Most current therapies, which include medical management, neurostimulation, and operative intervention, aim to minimize the symptoms caused by these conditions. The evidence base for many of these treatments in children is poor, and multiinstitutional prospective studies are needed. An innovative therapy on the horizon involves using neuronal stem cell transplantation to treat the underlying disorder by replacing the missing or damaged neurons in these diseases. SUMMARY Although recent advances in basic and clinical neurogastroenterology have significantly improved our awareness and understanding of enteric neuropathies, the efficacy of current treatment approaches is limited. The development of novel therapies, including pharmacologic modulators of neurointestinal function, neurostimulation to enhance gut motility, and neuronal cell-based therapies, is essential to improve the long-term outcomes in children with these disorders.

Abstract
Despite major advances in medical therapies late mortality after myocardial infarction (MI) is still high. A substantial proportion of post-MI patients die from sudden cardiac death. Prophylactic implantable-cardioverter defibrillator (ICD) therapy has been established for post-MI patients with reduced left ventricular ejection fraction (LVEF ≤35%). However, most patients who die after MI have an LVEF >35%. For this large group of patients, no specific prophylactic strategies exist. There is strong evidence that measures of cardiac autonomic dysfunction after MI provide important prognostic information in post-MI patients with preserved LVEF. Combinations of autonomic markers can identify high-risk patients after MI with LVEF >35% whose prognosis is equally worse than that of patients with LVEF ≤35%. The ongoing REFINE-ICD (NCT00673842) and SMART-MI trials (NCT02594488) test different preventive strategies in high-risk post-MI patients with cardiac autonomic dysfunction and LVEF 36-50%. While REFINE-ICD follows the traditional concept of ICD-implantation, SMART-MI uses implantable cardiac monitors with remote monitoring capabilities to sensitively detect asymptomatic, but prognostically relevant arrhythmias that could trigger specific diagnostic and therapeutic interventions.

Abstract
Autism spectrum disorder (ASD) is a developmental disorder marked by difficulty in social interactions and communication. ASD also often present symptoms of autonomic nervous system (ANS) functioning abnormalities. In individuals with autism the sympathetic branch of the ANS presents an over-activation on a background of the parasympathetic activity deficits, creating an autonomic imbalance, evidenced by a faster heart rate with little variation and increased tonic electrodermal activity. The objective of this study was to explore the effect of 12 sessions of 0.5 Hz repetitive transcranial magnetic stimulation (rTMS) over dorsolateral prefrontal cortex (DLPFC) on autonomic activity in children with ASD. Electrocardiogram and skin conductance level (SCL) were recorded and analyzed during each session of rTMS. The measures of interest were time domain (i.e., R-R intervals, standard deviation of cardiac intervals, NN50-cardio-intervals >50 ms different from preceding interval) and frequency domain heart rate variability (HRV) indices [i.e., power of high frequency (HF) and low frequency (LF) components of HRV spectrum, LF/HF ratio]. Based on our prior pilot studies it was proposed that the course of 12 weekly inhibitory low-frequency rTMS bilaterally applied to the DLPFC will improve autonomic balance probably through improved frontal inhibition of the ANS activity, and will be manifested in an increased length of cardiointervals and their variability, and in higher frequency-domain HRV in a form of increased HF power, decreased LF power, resulting in decreased LF/HF ratio, and in decreased SCL. Our post-12 TMS results showed significant increases in cardiac intervals variability measures and decrease of tonic SCL indicative of increased cardiac vagal control and reduced sympathetic arousal. Behavioral evaluations showed decreased irritability, hyperactivity, stereotype behavior and compulsive behavior ratings that correlated with several autonomic variables.

Abstract
BACKGROUND Obstructive sleep apnea hypopnea (OSAH) is associated with decreased exercise tolerance and autonomic abnormalities and represents a risk for cardiovascular diseases. The aim of the study was to evaluate the effects of CPAP on cardiovascular autonomic abnormalities and exercise performance in patients with OSAH without changes in lifestyle and body weight during treatment. METHODS Twelve overweight subjects with OSAH underwent anthropometric measures, autonomic cardiovascular and incremental symptom-limited cardio-respiratory exercise tests before and after two months of treatment with CPAP. RESULTS Lower frequency component of power spectrum of heart rate variability (59.5±24.2 msec2 vs 43.2±25.9 msec2; p<0.05) and improvements of maximal workload (99.3±13.5 vs 108.3±16.8%pred.; p<0.05) and peak oxygen consumption (95.3±7.6 vs 105.5±7.9%pred.; p<0.05) were observed in these patients after CPAP, being their BMI unchanged. CONCLUSIONS CPAP-induced decrease of sympathetic hyperactivity is associated with better tolerance to the effort in OSAH patients that did not change their BMI and lifestyle, suggesting that OSAH limits per se the exercise capacity.

Abstract
The aim of this study was to discuss the effect of autogenic training (AT) on patients with functional somatic syndrome (FSS) using salivary amylase, the skin temperature of the finger, subjective severity of symptoms, and psychological characteristics as measures. We assessed 20 patients with FSS and 23 healthy controls before and after AT. Baseline levels of salivary amylase prior to an AT session were significantly higher in the FSS group than in the control group. However, this difference was not significant after AT. The skin temperature of the finger increased after AT in both the FSS and control groups. AT contributed to the improvement of somatic symptoms in patients with FSS. Our results regarding psychological characteristics suggest that mood disturbances are deeply involved in the pathology of FSS. Individuals with FSS exhibited elevated levels of sympathetic activity compared with healthy controls. Our data indicates that AT eased dysregulation of the autonomic nervous system in patients with FSS. Thus, salivary amylase may be a useful index of change induced by AT in patients with FSS.

Abstract
AIMS Cardiovascular autonomic dysfunction, evaluated as baroreflex sensitivity (BRS), could be acutely corrected by slow breathing or oxygen administration in patients with type 1 diabetes, thus suggesting a functional component of the disorder. We tested this hypothesis in patients with the type 2 diabetes with or without renal impairment. METHODS Twenty-six patients with type 2 diabetes (aged 61.0 ± 0.8 years, mean ± SEM; duration of diabetes 10.5 ± 2 years, BMI 29.9 ± 0.7 kg/m(2), GFR 68.1 ± 5.6 ml/min) and 24 healthy controls (aged 58.5 ± 1.0 years) were studied. BRS was obtained from recordings of RR interval and systolic blood pressure fluctuations during spontaneous and during slow, deep (6 breaths/min) controlled breathing in conditions of normoxia or hyperoxia (5 l/min oxygen). RESULTS During spontaneous breathing, diabetic patients had lower RR interval and lower BRS compared with the control subjects (7.1 ± 1.2 vs. 12.6 ± 2.0 ms/mmHg, p < 0.025). Deep breathing and oxygen administration significantly increased arterial saturation, reduced RR interval and increased BRS in both groups (to 9.6 ± 1.8 and 15.4 ± 2.4 ms/mmHg, respectively, p < 0.05, hyperoxia vs. normoxia). Twelve diabetic patients affected by chronic diabetic kidney disease (DKD) presented a significant improvement in the BRS during slow breathing and hyperoxia (p < 0.025 vs. spontaneous breathing during normoxia). CONCLUSIONS Autonomic dysfunction present in patients with type 2 diabetes can be partially reversed by slow breathing, suggesting a functional role of hypoxia, also in patients with DKD. Interventions known to relieve tissue hypoxia and improve autonomic function, like physical activity, may be useful in the prevention and management of complications in patients with diabetes.

Abstract
The autonomic nervous system (ANS) provides homeostasis due to the innervation of the secretory glands, smooth muscle and cardiac muscle. Higher centers of the ANS (primarily the hypothalamus, some centers of the brain stem and limbic system) form a integrative network, which plays a key role in coordinating the functioning of the endocrine, immune system and other parts of the central nervous system. Intracranial centers of the ANS are responsible for the consciousness, behavioral, emotional, and other components of the higher nervous activity. Thus, the significance of the ANS can't be overestimated. At the same time today in neurointensive care there are no clear criteria for ANS dysfunction, we don't have universally recognized monitoring facilities for ANS and approaches to targeted therapy of its disorders. This paradox is even more important as in the pathogenesis of some critical conditions such as neurogenic pulmonary edema, stunned myocardium, cardiomyopathy Takotsubo lies precisely ANS imbalance. This review devoted to the ANS and some problems associated with its imbalance.

Abstract
The symptoms caused by gastrointestinal autonomic neuropathy in diabetes mellitus is important to highlight since it affects a large proportion of people with diabetes, regardless of whether this is type 1 or type 2. Gastroparesis and general signs of bowel dysfunction, such as constipation, diarrhoea and abdominal pain are most often encountered and involve both pharmacological and non-pharmacological treatment options. This mini-review summarises a presentation given at the 'Diagnosis and treatment of autonomic diabetic neuropathy in the gut' symposium at the 2015 annual meeting of the EASD. It is accompanied by another mini-review on a topic from this symposium (by Azpiroz and Malagelada, DOI: 10.1007/s00125-015-3831-1 ) and a commentary by the Session Chair, Péter Kempler (DOI: 10.1007/s00125-015-3826-y ).

Abstract
BACKGROUND Although a diversity of neurotransmitters and hormones participate in controlling blood pressure, norepinephrine released from postganglionic sympathetic nerve terminals is an important mediator of the rapid regulation of cardiovascular function required for homeostasis of cerebral perfusion. Hence, neurogenic orthostatic hypotension (NOH) often represents a deficiency of noradrenergic responsiveness to postural change. RESEARCH DESIGN AND METHODS PubMed searches with 'orthostatic hypotension' and 'norepinephrine' as conjoint search terms and no restriction on language or date, so as to survey the pathophysiologic and clinical relevance of norepinephrine deficiency for current NOH interventions and for future directions in treatment and research. RESULTS Norepinephrine deficiency in NOH can arise peripherally, due to cardiovascular sympathetic denervation (as in pure autonomic failure, Parkinson's disease, and a variety of neuropathies), or centrally, due to a failure of viscerosensory signals to generate adequate sympathetic traffic to intact sympathetic nerve endings (as in multiple system atrophy). Nonpharmacologic countermeasures such as pre-emptive water intake may yield blood-pressure increases exceeding those achieved pharmacologically. For patients with symptomatic NOH unresponsive to such strategies, a variety of pharmacologic interventions have been administered off-label on the basis of drug mechanisms expected to increase blood pressure via blood-volume expansion or vasoconstriction. Two pressor agents have received FDA approval: the sympathomimetic midodrine and more recently the norepinephrine prodrug droxidopa. CONCLUSIONS Pressor agents are important for treating symptomatic NOH in patients unresponsive to lifestyle changes alone. However, the dysautonomia underlying NOH often permits blood-pressure excursions toward both hypotension and hypertension. Future research should aim to shed light on the resulting management issues, and should also explore the possibility of pharmacotherapy selectively targeting orthostatic blood-pressure decreases.

Abstract
Spinal cord injuries (SCI) affect all organs and may cause multiple sequelae. Complications after SCI can be life-threatening and socially disabling. Furthermore, a spinal cord injury is often a chronic condition and the patient may have contact with both the general practitioner and several departments in a hospital. Thus, it is important for all doctors to recognize risks and morbidities related to SCI, in order to prevent and treat the short- and long-term complications and disabilities. This article systematically describes the most commonly encountered sequelae after SCI.

Abstract
Diabetes mellitus is associated with a series of macrovascular and microvascular changes that can manifest as a wide range of complications. Foot ulcerations affect ∼2-4% of patients with diabetes mellitus. Risk factors for foot lesions include peripheral and autonomic neuropathy, vascular disease and previous foot ulceration, as well as other microvascular complications, such as retinopathy and end-stage renal disease. Ulceration is the result of a combination of components that together lead to tissue breakdown. The most frequently occurring causal pathways to the development of foot ulcers include peripheral neuropathy and vascular disease, foot deformity or trauma. Peripheral vascular disease is often not diagnosed in patients with diabetes mellitus until tissue loss is evident, usually in the form of a nonhealing ulcer. Identification of patients with diabetes mellitus who are at high risk of ulceration is important and can be achieved via annual foot screening with subsequent multidisciplinary foot-care interventions. Understanding the factors that place patients with diabetes mellitus at high risk of ulceration, together with an appreciation of the links between different aspects of the disease process, is essential to the prevention and management of diabetic foot complications.

Abstract
Stress related disorders such as depression and anxiety are leading sources of disability worldwide, and current treatment methods such as conventional antidepressant medications are not beneficial for all individuals. There is evidence that yoga has mood-enhancing properties possibly related to its inhibitory effects on physiological stress and inflammation, which are frequently associated with affective disorders. However the biological mechanisms via which yoga exerts its therapeutic mood-modulating effects are largely unknown. This systematic review investigates the effects of yoga on sympathetic nervous system and hypothalamic pituitary adrenal axis regulation measures. It focuses on studies collecting physiological parameters such as blood pressure, heart rate, cortisol, peripheral cytokine expression and/or structural and functional brain measures in regions involved in stress and mood regulation. Overall the 25 randomised control studies discussed provide preliminary evidence to suggest that yoga practice leads to better regulation of the sympathetic nervous system and hypothalamic-pituitary-adrenal system, as well as a decrease in depressive and anxious symptoms in a range of populations. Further research is warranted to confirm these preliminary findings and facilitate implementation in clinical settings.

Abstract
Chronic intestinal pseudoobstruction (CIP) can be a severe burden and even a life-threatening disorder. Typically, several years of uncertainty are passing before diagnosis. We are reporting the case of a young woman with a decade of severe, progressive gastrointestinal dysmotility. Unusually, she had also developed an autonomic neuropathy, and a stiff limb syndrome.In addition to achalasia and CIP the young woman also developed neuropathic symptoms: orthostatic intolerance, urinary retention, a Horner syndrome, and lower limb stiffness. Careful interdisciplinary diagnostics excluded underlying infectious, rheumatoid, metabolic or tumorous diseases.The detection of GAD (glutamic acid decarboxylase) antibodies, however, seemed to link CIP, autonomic neuropathy, and limb stiffness and pointed at an autoimmune origin of our patient's complaints. This was supported by the positive effects of intravenous immunoglobulin. In response to this therapy the body weight had stabilized, orthostatic tolerance had improved, and limb stiffness was reversed.The case suggested that GAD antibodies should be considered in CIP also in nondiabetic patients. This may support earlier diagnosis and immunotherapy.

Abstract
OBJECTIVE To compare the clinical efficacy difference in dysantonomia between transcutaneous electrical stimulation at Renying(ST 9) combined with stellate ganglion block(SGB) and simple SGB. METHODS Sixty patients in accord with the diagnostic criteria of dysantonomia were randomly divided into two groups,30 cases in each group. In the observation group,transcutaneous electrical stimulation at Renying(ST 9) combined with SGB were adopted; in the control group,simple SGB was applied. In the two groups, treatment was used three times a week,and nine treatments were considered as one course. There was an interval of one week between courses,and two courses were treated. Total seven weeks were required. Scores were evaluated according to subjective symptoms before treatment,one month and three months after treatment in the two groups. RESULTS The scores of subjective symptoms were not statistically different before treatment in the two groups(P>0. 05). The scores of subjective symptoms one month and three months after treatment were all lower than those before treatment(all P< 0. 01), and subjective symptoms scores in the observation group were lower than those in the control group(both P<0. 01). CONCLUSION Transcutaneous electrical stimulation at Renying(ST 9) combined with SGB could obviously enhance the clinical effects for dysantonomia, and the control and improvement for clinical symptoms are apparently superior to simple SGB.

Abstract
Vegetative neuropathy of the vertebral component of the spinal nerve was identified based on the results of dynamic segmental diagnosis in the course of medical rehabilitation of 390 patients presenting with dorsopathies. 153 patients experienced segmental autonomous imbalance at the level of the vertebral-motor segments (VMS) of the spinal column. This neuropathy was characterized by the increased sympathetic influence on the tissues of VMS in 85 patients and the impaired sympathetic regulation of the VMS tissue in the remaining 68 patients. Interference-electropuncture (IFEP) as the method for the influence on the biologically active points by interference currents was included in the complex of rehabilitative measures in a group of 51 patients. IFEP parameters were selected on an individual basis taking into consideration the segmental mechanisms of vegetative regulation. The results of medical rehabilitation of these patients were substantially better and significantly different from the results of the treatment of other patients managed with the use of standard medicamental therapy and physiotherapy. At the same time, the patients with dorsopathies receiving IFEP reported a more pronounced alleviation of pain, regression of muscle-tonic manifestations, and improvement of the indicators of the quality of life associated with the improvement of vertebroneurological symptoms.

Abstract
Paragangliomas (PGLs) are rare vascular, neuroendocrine tumors of paraganglia, which are associated with either sympathetic tissue in adrenal (pheochromocytomas (PCCs)) and extraadrenal (sympathetic paraganglioma (sPGLs)) locations or parasympathetic tissue of the head and neck paragangliomas (HNPGLs). As HNPGLs are usually benign and most tumors grow slowly, a wait-and-scan policy is often advised. However, their location in the close proximity to cranial nerves and vasculature may result in considerable morbidity due to compression or infiltration of the adjacent structures, necessitating balanced decisions between a wait-and-see policy and active treatment. The main treatment options for HNPGL are surgery and radiotherapy. In contrast to HNPGLs, the majority of sPGL/PCCs produces catecholamines, in advanced cases resulting in typical symptoms and signs such as palpitations, headache, diaphoresis, and hypertension. The state-of-the-art diagnosis and localization of sPGL/PCCs are based on measurement of plasma and/or 24-h urinary excretion of (fractionated) metanephrines and methoxytyramine (MT). sPGL/PCCs can subsequently be localized by anatomical (computed tomography and/or magnetic resonance imaging) and functional imaging studies (123I-metaiodobenzylguanidine-scintigraphy, 111In-pentetreotide scintigraphy, or positron emission tomography with radiolabeled dopamine or dihydroxyphenylalanine). Although most PGL/PCCs are benign, factors such as genetic background, tumor size, tumor location, and high MT levels are associated with higher rates of metastatic disease. Surgery is the only curative treatment. Treatment options for patients with metastatic disease are limited. PGL/PCCs have a strong genetic background, with at least one-third of all cases linked with germline mutations in 11 susceptibility genes. As genetic testing becomes more widely available, the diagnosis of PGL/PCCs will be made earlier due to routine screening of at-risk patients. Early detection of a familial PGL allows early detection of potentially malignant PGLs and early surgical treatment, reducing the complication rates of this operation.

Abstract
The maintenance of blood pressure in the upright position requires intact autonomic cardiovascular reflexes. Diseases that affect the sympathetic innervation of the cardiovascular system result in a sustained fall in blood pressure upon standing (i.e., neurogenic orthostatic hypotension) that can impair the blood supply to the brain and other organs and cause considerable morbidity and mortality. Here we review treatment options for neurogenic orthostatic hypotension and include an algorithm for its management that emphasizes the importance of non-pharmacologic measures and provides guidance on pharmacologic treatment options.

Abstract
BACKGROUND Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) or with cranial autonomic symptoms (SUNA) are primary headaches characterized by frequent attacks of severe headaches in association with cranial autonomic features. Patients with chronic SUNCT or SUNA have unremitting symptoms that necessitate prolonged use of medical preventive treatments, many of which are prone to causing side effects. They can be medically intractable, in which case neurally destructive or cranially invasive surgical treatments can be offered, though these have hitherto yielded conflicting results. Occipital nerve stimulation (ONS) offers a nondestructive and relatively low risk surgical alternative. OBJECTIVE To assess the efficacy and safety of ONS in chronic, medically intractable SUNCT and SUNA patients. STUDY DESIGN Prospective open-label study. METHODS Nine medically intractable, chronic SUNCT and SUNA patients were implanted with electrodes for bilateral occipital nerve stimulation. Data were collected prospectively for pre- and postimplantation headache characteristics, including frequency, intensity and duration of attacks. Diaries were used to assess headache improvement. RESULTS At a median follow-up of 38 months (range 24-55 months), all but one patient reported substantial improvement. Four patients became pain-free, 3 were almost pain-free (96 - 98% improvement), and one had a marked reduction in attack frequency and severity (81% improvement). After an initial rapid improvement, the maximum benefit of ONS was attained after a lag of a few months. Device malfunction was followed by recurrence or worsening of the attacks within a few days in most patients. Adverse events included lead migration, exposure of the electrode, and pain due to muscle recruitment over the leads. One patient developed hemicrania continua one month after implantation and was successfully treated with indomethacin. CONCLUSION ONS appears to offer an effective and safe treatment option, without significant morbidity, for medically intractable SUNCT and SUNA. Given the variable results with cranially invasive or neurally destructive surgery, ONS might be considered the surgical treatment of choice for medically intractable SUNCT and SUNA.

Abstract
OBJECTIVE To explore a role, place and effectiveness of different therapeutic methods in sanatorium care. MATERIAL AND METHODS We compared volume and structure of therapeutic methods of treatment of autonomic nervous system disorders in 571 patients of a neurological sanatorium and 924 patients of a cardiologic sanatorium. RESULTS AND CONCLUSION The actual volume and structure of the therapeutic methods in sanatoriums differed from republican standards. This can be explained by the aspiration of physicians to individualize treatment. Treatment outcome was correlated with the volume and structure of therapeutic methods. Sensitivity, specificity and predictive value of some methods were defined. Barotherapy, oxygen influence and psychotherapy predicted the effectiveness of different therapeutic methods in sanatorium care of patients with autonomic nervous system disorders.
