Abstract
OBJECTIVE Paroxysmal sympathetic hyperactivity (PSH) is a life-threatening neurological emergency associated with severe brain injury. Stroke-related PSH, particularly post-aneurysmal subarachnoid hemorrhage (aSAH) PSH, has been relatively understudied and is often misdiagnosed as an aSAH-related hyperadrenergic crisis. This study aims to clarify the feature of stroke-related PSH. METHODS This study discusses the case of a patient with post-aSAH PSH and identifies 19 articles (25 cases) on stroke-related PSH by searching the PubMed database from 1980 to 2021. RESULTS In the total cohort, 15 (60.0%) patients were male and the average age was 40.1 ± 16.6 years. The primary diagnoses included intracranial hemorrhage (13 cases, 52.0%), cerebral infarction (7 cases, 28.0%), subarachnoid hemorrhage (4 cases, 16.0%), and intraventricular hemorrhage (1 case, 4.0%). The sites of stroke damage were predominantly the cerebral lobe (10 cases, 40.0%), basal ganglia (8 cases, 32.0%), and the pons (4 cases, 16.0%). The median time of PSH onset after admission was 5 (1-180) days. Most cases employed combination therapy with sedation drugs, beta-blockers, gabapentin, and clonidine. On the Glasgow Outcome Scale, outcomes included death (4 cases, 21.1%), vegetative state (2 cases, 10.5%), severe disability (7 cases, 36.8%), and in only one case (5.3%) was a good recovery noted. CONCLUSIONS The clinical features and treatment of post-aSAH PSH differed from those of aSAH-related hyperadrenergic crises. Early diagnosis and treatment can prevent severe complications. PSH should be acknowledged as a potential complication of aSAH. Differential diagnosis can aid in developing individualized treatment plans and improving patient prognosis.

Abstract
The Autonomic Nervous System (ANS) is a critical part of the homeostatic machinery with both central and peripheral components. However, little is known about the integration of these components and their joint role in the maintenance of health and in allostatic derailments leading to somatic and/or neuropsychiatric (co)morbidity. Based on a comprehensive literature search on the ANS neuroanatomy we dissect the complex integration of the ANS: (1) First we summarize Stress and Homeostatic Equilibrium - elucidating the responsivity of the ANS to stressors; (2) Second we describe the overall process of how the ANS is involved in Adaptation and Maladaptation to Stress; (3) In the third section the ANS is hierarchically partitioned into the peripheral/spinal, brainstem, subcortical and cortical components of the nervous system. We utilize this anatomical basis to define a model of autonomic integration. (4) Finally, we deploy the model to describe human ANS involvement in (a) Hypofunctional and (b) Hyperfunctional states providing examples in the healthy state and in clinical conditions.

Abstract
Paroxysmal sympathetic hyperactivity (PSH) occurs in ∼10% of patients following acute severe brain injury. While PSH is associated with worse outcomes, there are no clinical practice guidelines to inform treatment. We aimed to systematically review the literature on the pharmacological management of PSH. MEDLINE, Embase, and Cochrane library databases were searched from inception to August 2020. Eligible studies met the following criteria: 1) randomized controlled trials, non-randomized controlled trials (case control or controlled cohort), observational studies, case series, and case reports; 2) study population of adult and pediatric patients; 3) exposure to an acute neurological insult complicated by PSH (or historic synonym); 4) description of pharmacological treatment of PSH. Our search retrieved 2729 citations with 83 articles assessed for inclusion. After full text extraction, 56 manuscripts inclusive of 459 patients met eligibility criteria. We identified 31 case reports, 15 case series (152 patients), seven retrospective case control or cohort studies (212 patients), and three prospective observational studies (52 patients). Traumatic brain injury was the most common precipitating insult (407 patients), followed by hypoxic encephalopathy (72 patients) and intracranial hemorrhage (10 patients). There were 48 drugs from 22 classes prescribed for the management of PSH. The most frequently prescribed agents were benzodiazepines, β-blockers, opioids, α-2 agonists, and baclofen. However, route and dose of drug and subsequent outcome were inconsistently reported, such that no summary was possible. While a wide variety of drugs have been reported to treat PSH, there is a lack of even moderate-quality evidence to inform clinical decision making.

Abstract
BACKGROUND AND PURPOSE Paroxysmal sympathetic hyperactivity (PSH) is a rare complication of spontaneous intracerebral hemorrhage (ICH).We aimed to evaluate the risk factors and clinical features for PSH after ICH. METHODS From January 1, 2013 to April 1, 2018, patients with ICH were consecutively included in this observational study. Baseline characteristics were compared in patients with and without PSH. Multivariate logistic regression analysis was used to determine the risk factors associated with PSH development. Clinical features of patients with PSH were also analyzed. RESULTS There were 548 patients with ICH included and a total of 15 (2.7%) patients were identified with PSH. In univariate analysis, PSH development was associated with the following: previous hemorrhagic stroke, pupils abnormity, admission Glasgow Coma Scale (GCS) score, hematoma volume, liver function abnormity, neutrophil count and early tracheostomy. Multivariate logistic regression analysis showed that a significantly increased risk of PSH was found in patients with previous hemorrhagic stroke (odds ratio [OR], 4.176; 95% confidence interval [CI], 1.111-15.698), admission GCS score (OR, 0.703; 95% CI, 0.548-0.902) and early tracheostomy (OR, 8.317; 95%CI, 1.755-39.412).The most common symptoms of PSH were hyperthermia (80%) and hyperhidrosis (80%).The median Intensive Care Unit stays and Glasgow Outcome Scale at discharge were 34 (19-46) and 2 (1.5-3), respectively. CONCLUSIONS PSH is characterized by a cluster of symptoms and abnormal vital signs, which may lead to poor outcomes in ICH. The present study suggests that previous hemorrhagic stroke, admission GCS score and early tracheostomy may be the significant risk factors for PSH after ICH.

Abstract
We report a case of pharmacologic management of pediatric paroxysmal sympathetic hyperactivity (PSH) in a patient who experienced symptomatic resolution with dexmedetomidine and propranolol. Following a blunt traumatic subdural hematoma and diffuse axonal injury, an 8-year-old male developed PSH on approximately day 5 of the hospitalization. PSH symptoms identified in this patient were hyperthermia, tachycardia, posturing, and hypertension with associated elevations in intracranial pressure. Episodes of PSH continued to be observed despite appropriate titration of opiates, sedatives, and traditional blood pressure management. Dexmedetomidine and propranolol were subsequently initiated to attenuate acute episodes of PSH. A reduction in sedative requirements and improvement in symptoms followed, which facilitated successful extubation. The combination of propranolol and dexmedetomidine was followed by a decrease in the frequency and severity of acute episodes of PSH. After utilization of multiple treatment modalities to control PSH episodes in our patient, propranolol and dexmedetomidine may have helped attenuate PSH signs and symptoms.

Abstract
Traumatic brain injury (TBI) is a common disorder with high morbidity and mortality, accounting for one in every three deaths due to injury. Older adults are especially vulnerable. They have the highest rates of TBI-related hospitalization and death. There are about 2.5 to 6.5 million US citizens living with TBI-related disabilities. The cost of care is very high. Aside from prevention, little can be done for the initial primary injury of neurotrauma. The tissue damage incurred directly from the inciting event, for example, a blow to the head or bullet penetration, is largely complete by the time medical care can be instituted. However, this event will give rise to secondary injury, which consists of a cascade of changes on a cellular and molecular level, including cellular swelling, loss of membrane gradients, influx of immune and inflammatory mediators, excitotoxic transmitter release, and changes in calcium dynamics. Clinicians can intercede with interventions to improve outcome in the mitigating secondary injury. The fundamental concepts in critical care management of moderate and severe TBI focus on alleviating intracranial pressure and avoiding hypotension and hypoxia. In addition to these important considerations, mechanical ventilation, appropriate transfusion of blood products, management of paroxysmal sympathetic hyperactivity, using nutrition as a therapy, and, of course, venous thromboembolism and seizure prevention are all essential in the management of moderate to severe TBI patients. These concepts will be reviewed using the recent 2016 Brain Trauma Foundation Guidelines to discuss best practices and identify future research priorities.

Abstract
Background Paroxysmal Sympathetic Hyperactivity (PSH) is a frequently observed condition among critically ill patients on intensive care units. According to different studies, PSH is associated with worse recovery and increased mortality in acute-care facilities. In this monocentric, retrospective case-control study, we investigated whether this association also applies to post-acute neurological early rehabilitation. Methods The study included n = 387 patients, admitted to an intensive care or intermediate care unit within 1 year (2016). Among these, 97 patients showed clinical signs of PSH. For each patient with PSH, a patient without PSH was identified, controlling for age, gender, functional and respiratory status upon admission. However, for 25 patients with PSH, there was no suitable control patient fulfilling all defined matching criteria. Primary outcome was type of discharge, dichotomized into favorable (follow-up rehabilitation) and unfavorable outcome (all others). Secondary outcome measures were functional and respiratory status, number of secondary diagnoses, duration of treatment interruptions and length of stay at discharge. Results About 25% of neurological early rehabilitation patients showed clinical signs of PSH. A young age (OR = 0.94; CI = 0.91–0.97) and less severe PSH symptoms (OR = 0.79; CI = 0.69–0.90) were independent predictors of a favorable outcome. In addition, severity of PSH symptoms was associated with weaning duration, while the occurrence of PSH symptoms alone had no influence on most secondary outcome variables. The treatment on intermediate care units proved to be longer for patients with PSH symptoms, only. Conclusions Patients with PSH represent a large group of neurological early rehabilitation patients. Overall, we did not find PSH-related differences in most of the examined outcome measures. However, severe PSH symptoms seem to be associated with poorer outcome and longer treatment on intermediate care units, in order to prevent possible complications.

Abstract
Paroxysmal sympathetic hyperactivity (PSH) is a clinical syndrome of agitation and involuntary motor activity that particularly occurs in patients with severe acquired brain injury. The aim of the present study is to substantiate the assertion that paroxysmal non-epileptic attacks resembling PSH also occur in patients with Juvenile Neuronal Ceroid Lipofuscinosis (JNCL, Batten disease), which is the most common neurodegenerative disease in children. The paper describes a case series of five patients with JNCL which during a period of fifteen years have been followed clinically and by consecutive investigations of the autonomic nervous system using heart rate variability (HRV) investigations. Following adolescence a significant autonomic imbalance with very low parasympathetic activity and an unchanged high sympathetic excitatory activity was documented. In addition, episodes of anxiety and agitation combined with involuntary movements were reported. Beyond the frightened facial expression and involuntary increased motor activity, excessive sweating, increased body temperature, high heart and respiratory rates were reported, and typically, the episodes occurred to stimuli that were either non-nociceptive or only minimally nociceptive. Thus, from a clinical point of view the non-epileptic paroxysmal condition with anxious behavior, agitation and motor hyperactivity seen in patients with JNCL fits to the clinical description of PSH which normally occurs following acutely acquired brain injury, and as the neuropathological basis in JNCL for development of PSH is similar to what is seen in patients with traumatic brain injuries, it seems reasonable to propose that PSH also occurs following adolescence in patients with JNCL.

Abstract
Autonomic dysfunction is common in neuro-critical care patients and may compromise the function of various organs. Among the many diseases causing or being associated with autonomic dysfunction are traumatic brain injury, cerebrovascular diseases, epilepsy, Guillain-Barré syndrome (GBS), alcohol withdrawal syndrome, botulism and tetanus, among many others. Autonomic dysfunction may afflict various organs and may involve hyper- or hypo-activity of the sympathetic or parasympathetic system. In this short overview, we address only a small number of neuro-intensive care diseases with autonomic dysfunction. In GBS, autonomic dysfunction is frequent and may account for increased mortality rates; rapid changes between sympathetic and parasympathetic hypo- or hyper-activity may cause life-threatening cardiovascular complications. Paroxysmal sympathetic hyperactivity occurs after brain injury, hypoxia and cerebrovascular and other events, causes paroxysmal tachycardia, hypertension, tachypnoea and hyperthermia and is associated with a poorer prognosis and prolonged intensive care treatment. Other, at times life-threatening autonomic complications with exaggerated sympathetic activity and compromised baroreflex sensitivity arise during the alcohol withdrawal syndrome triggered by abrupt cessation of alcohol consumption. Botulism and tetanus are examples of life-threatening autonomic dysfunction caused by bacterial neurotoxins. Common neurological diseases, such as epilepsy, stroke or subarachnoid haemorrhage, are also associated with autonomic dysfunction that can on occasion cause critical deterioration of disease severity and prognosis.

Abstract
OBJECTIVE After traumatic brain injury (TBI), there may be persistent central-autonomic-network (CAN) dysfunction causing cardiovascular-autonomic dysregulation. Eyeball-pressure-stimulation (EPS) normally induces cardiovagal activation. In patients with a history of moderate or severe TBI (post-moderate-severe-TBI), we determined whether EPS unveils cardiovascular-autonomic dysregulation. METHODS In 51 post-moderate-severe-TBI patients (32.7 ± 10.5 years old, 43.1 ± 33.4 months post-injury), and 30 controls (29.1 ± 9.8 years), we recorded respiration, RR-intervals (RRI), systolic and diastolic blood-pressure (BPsys, BPdia), before and during EPS (120 sec; 30 mmHg), using an ocular-pressure-device (Okulopressor®). We calculated spectral-powers of mainly sympathetic low (LF: 0.04-0.15 Hz) and parasympathetic high (HF: 0.15-0.5 Hz) frequency RRI-fluctuations, sympathetically mediated LF-powers of BPsys, and calculated normalized (nu) LF- and HF-powers of RRI. We compared parameters between groups before and during EPS by repeated-measurement-analysis-of-variance with post-hoc analysis (significance: p < 0.05). RESULTS At rest, sympathetically mediated LF-BPsys-powers were significantly lower in the patients than the controls. During EPS, only controls significantly increased RRIs and parasympathetically mediated HFnu-RRI-powers, but decreased LF-RRI-powers, LFnu-RRI-powers, and LF-BPsys-powers; in contrast, the patients slightly though significantly increased BPsys upon EPS, without changing any other parameter. CONCLUSIONS In post-moderate-severe-TBI patients, autonomic BP-modulation was already compromised at rest. During EPS, our patients failed to activate cardiovagal modulation but slightly increased BPsys, indicating persistent CAN dysregulation. SIGNIFICANCE Our findings unveil persistence of subtle cardiovascular-autonomic dysregulation even years after TBI.

Abstract
Dysautonomia is a potentially life-threatening syndrome seen in many different types of brain injuries. It involves paroxysmal sympathetic hyperactivity and typically includes a constellation of symptoms, including: tachycardia, tachypnea, hyperthermia, hypertension, diaphoresis, hypertonia, and/or decerebrate or decorticate posturing. It is a clinical diagnosis of exclusion. A multimodal treatment approach is necessary including environmental modifications along with pharmacotherapy. Early management can help prevent comorbidities including secondary brain injury while also improving patient outcomes. This discussion serves as an overview of dysautonomia with a focus on management in the pediatric population including an example of a clinical algorithm and a review of the commonly used medications.

Abstract
Introduction. Central hyperthermia is common in patients with brain injury. It typically has a rapid onset with high temperatures and marked fluctuations and responds poorly to antibiotics and antipyretics. It is also associated with worse outcomes in the brain injured patient. Recognizing this, it is important to aggressively manage it. Case Report. We report a 34-year-old male with a right thalamic hemorrhage extending to the midbrain and into the ventricles. During his admission, he developed intractable fevers with core temperatures as high as 39.3°C. Infectious workup was unremarkable. The fever persisted despite empiric antibiotics, antipyretics, and cooling wraps. Bromocriptine was started resulting in control of the central hyperthermia. The fever spikes were reduced to minor fluctuations that significantly worsened with any attempt to wean off the bromocriptine. Conclusion. Diagnosing and managing central hyperthermia can be challenging. The use of bromocriptine can be beneficial as we have reported.

Abstract
Background Paroxysmal sympathetic hyperactivity (PSH) results and aggravates in secondary brain injury, which seriously affects the prognosis of severe traumatic brain injury patients. Although several studies have focused on the treatment of PSH, few have concentrated on its prevention. Methods Ninety post-operation (post-op) severe traumatic brain injury (sTBI) patients admitted from October 2014 to April 2016 were chosen to participate in this study. Fifty of the post-op sTBI patients were sedated with dexmedetomidine and were referred as the “dexmedetomidine group” (admitted from May 2015 to April 2016). The other 40 patients (admitted from October 2014 to May 2015) received other sedations and were referred as the “control group.” The two groups were then compared based on their PSH scores and the scores and ratios of those patients who met the criteria of “probable,” “possible” and “unlikely” using the PSH assessment measure (PSH-AM) designed by Baguley et al. (2014). The durations of the neurosurgery intensive care unit (NICU) and hospital stays and the Glasgow outcome scale (GOS) values for the two groups were also compared to evaluate the therapeutic effects and the patients’ prognosis. Results The overall PSH score for the dexmedetomidine group was 5.26 ± 4.66, compared with 8.58 ± 8.09 for the control group. The difference between the two groups’ PSH scores was significant (P = 0.017). The score of the patients who met the criterion of “probable” was 18.33 ± 1.53 in the dexmedetomidine group and 22.63 ± 2.97 in the control group, and the difference was statistically significant (P = 0.045). The ratio of patients who were classified as “unlikely” between the two groups was statistically significant (P = 0.028); that is, 42 (84%) in the dexmedetomidine group and 25 (62.5%) in the control group. The differences in NICU, hospital stays and GOS values between the two groups were not significant. Conclusion Dexmedetomidine has a preventive effect on PSH in sTBI patients who have undergone surgery.

Abstract
Paroxysmal autonomic instability with dystonia (PAID) appears to be a unique syndrome following brain injury. It can echo many life-threatening conditions, making its early recognition and management a challenge for intensivists. A delay in early recognition and subsequent management may result in increased morbidity, which is preventable in affected patients. Herein, we report the case of a patient who was diagnosed with PAID syndrome following prolonged cardiac arrest, and discuss the pathophysiology, clinical presentation and management of this rare and under-recognised clinical entity.

Abstract
Paroxysmal sympathetic hyperactivity (PSH) is a life-threatening condition characterized by hyperadrenergic activity and autonomic dysfunction. Also termed autonomic storms, PSH can occur after a variety of cerebral insults, most commonly traumatic brain injury. Limited pediatric literature is available, especially in patients with brain injury from hypoxia. No consensus exists for the terminology, diagnostic criteria, or treatment algorithm for PSH. Thus, the optimal management, including medication selection and dosing, remains unclear. We present the detailed treatment of a 9-year-old, African American male with hypoxic brain injury after pulseless arrest following status asthmaticus, who subsequently developed PSH. The patient began to experience episodes of tachycardia, hypertension, tachypnea, diaphoresis, rigidity, and dystonic posturing on hospital day 5. After ruling out other potential causes, a diagnosis of PSH was made. Episodes of PSH failed to respond to lorazepam or labetalol but were aborted successfully with morphine. Management of PSH after hypoxic brain injury required medications for acute treatment as well as for prevention of PSH. Morphine was found to be highly effective and safe for aborting the autonomic crises. Other agents more commonly described in the literature did not result in an adequate response and were associated with significant adverse effects. A combination of clonazepam, baclofen, and either propranolol or clonidine aided in reducing the frequency of episodes of PSH. We suggest using morphine for aborting severe episodes of PSH that do not respond to antihypertensive agents or benzodiazepines.

Abstract
Paroxysmal sympathetic hyperactivity (PSH) is a common complication of various acquired brain injuries such as traumatic brain injury, subarachnoid hemorrhage, anoxic brain injury, intracerebral hemorrhage, and others. It is manifested by tachycardia, hypertension, tachypnea, diaphoresis, and dystonic posturing. The development of PSH can prolong hospitalization and lead to secondary brain injury and even death. Despite the awareness of the serious clinical impact, there is no consensus on diagnostic criteria. Thus, misdiagnosis and delayed recognition is very common. Most of the current treatment programs come from case reports and small case series; there are very few large-scale randomized controlled trials. Generally accepted medications are opioids, β-blockers and gabapentin (usually used in combination). However, the efficacy of these drugs has not been systematically assessed. The purpose of this review is to determine the treatment strategies and drugs commonly used for PSH at the overall level.

Abstract
Background: Paroxysmal sympathetic hyperactivity (PSH) is a condition occurring in a small percentage of patients with severe traumatic brain injury (TBI). It is characterized by a constellation of symptoms associated with excessive adrenergic output, including tachycardia, hypertension, tachypnea, and diaphoresis. Diagnosis is one of exclusion and, therefore, is often delayed. Treatment is aimed at minimizing triggers and pharmacologic management of symptoms. Methods: A literature review using medline and cinahl was conducted to identify articles related to PSH. Search terms included paroxysmal sympathetic hyperactivity, autonomic storming, diencephalic seizures, and sympathetic storming. Reference lists of pertinent articles were also reviewed and these additional papers were included. Results: The literature indicates that the understanding of PSH following TBI is in its infancy. The majority of information is based on small case series. The review revealed treatments that may be useful in treating PSH. Conclusions: Nurses play a critical role in the identification of at-risk patients, symptom complexes, and in the education of family. Early detection and treatment is likely to decrease overall morbidity and facilitate recovery. Further research is needed to establish screening tools and treatment algorithms for PSH.

Abstract
Diencephalic storms or paroxysmal sympathetic storms are characterized by episodic hyperhidrosis, hypertension, tachypnea, tachycardia, and abnormal posturing. These have been reported to occur in patients with hydrocephalus, intracranial tumors, and hypoxic, ischemic, or traumatic brain injury. They can be easily misdiagnosed as seizures, uncontrolled pheochromocytoma, drug withdrawal, thyroid storm, hypertensive crises, and sepsis or anxiety attacks. The most effective treatment to control these symptoms is yet to be identified. We present 2 individuals exhibiting these sympathetic surges; one whose symptoms were controlled with phenobarbital and the other with clonidine and oxycodone. Palliative medicine physicians should be made aware of this unusual complication.

Abstract
Mixed autonomic hyperactivity disorder (MAHD) among patients with acquired brain injury can be rare. A delayed diagnosis of MAHD might exacerbate the clinical outcome and increase healthcare expenses with unnecessary testing. However, MAHD is still an underrecognized and evolving disease entity. A 25-yr-old woman was admitted the clinic due to craniopharyngioma. After an extensive tumor resection, she complained of sustained fever, papillary contraction, hiccup, lacrimation, and sighing. An extensive evaluation of the sustained fever was conducted. Finally, the cause for MAHD was suspected, and the patient was successfully treated with bromocriptine for a month.

Abstract
BACKGROUND Dysautonomia after severe traumatic brain injury (TBI) is a clinical syndrome affecting a subgroup of survivors and is characterized by episodes of autonomic dysregulation and muscle overactivity. The purpose of this study was to determine the incidence of dysautonomia after severe TBI in an intensive care unit setting and analyze the risk factors for developing dysautonomia. METHODS A consecutive series of 101 patients with severe TBI admitted in a major trauma hospital during a 2-year period were prospectively observed to determine the effects of age, sex, mode of injury, hypertension history, admission systolic blood pressure, fracture, lung injury, admission Glasgow Coma Scale (GCS) score, injury severity score, emergency craniotomy, sedation or analgesia, diffuse axonal injury (DAI), magnetic resonance imaging (MRI) scales, and hydrocephalus on the development of dysautonomia. Risk factors for dysautonomia were evaluated by using logistic regression analysis. RESULTS Seventy-nine of the 101 patients met inclusion criteria, and dysautonomia was observed in 16 (20.3%) of these patients. Univariate analysis revealed significant correlations between the occurrence of dysautonomia and patient age, admission GCS score, DAI, MRI scales, and hydrocephalus. Sex, mode of injury, hypertension history, admission systolic blood pressure, fracture, lung injury, injury severity score, sedation or analgesia, and emergency craniotomy did not influence the development of dysautonomia. Multivariate logistic regression revealed that patient age and DAI were two independent predictors of dysautonomia. There was no independent association between dysautonomia and admission GCS score, MRI scales, or hydrocephalus. CONCLUSIONS Dysautonomia frequently occurs in patients with severe TBI. A younger age and DAI could be risk factors for facilitating the development of dysautonomia.

Abstract
The term 'paroxysmal autonomic instability with dystonia' was first given for a group of symptoms comprising diaphoresis, intermittent agitation, hypertension, hyperthermia, tachycardia, tachypnea, and extensor posturing. This usually occurs as a complication of severe brain injury and is infrequently reported in cases of cerebral infection. We report a 1-year-old child with intracranial tuberculoma with symptoms of paroxysmal autonomic instability with dystonia. Pertinent literature is reviewed emphasizing pathophysiology and available treatment options.

Abstract
Severe excessive autonomic overactivity occurs in a subgroup of people surviving acquired brain injury, the majority of whom show paroxysmal sympathetic and motor overactivity. Delayed recognition of paroxysmal sympathetic hyperactivity (PSH) after brain injury may increase morbidity and long-term disability. Despite its significant clinical impact, the scientific literature on this syndrome is confusing; there is no consensus on nomenclature, etiological information for diagnoses preceding the condition is poorly understood, and the evidence base underpinning our knowledge of the pathophysiology and management strategies is largely anecdotal. This systematic literature review identified 2 separate categories of paroxysmal autonomic overactivity, 1 characterized by relatively pure sympathetic overactivity and another group of disorders with mixed parasympathetic/sympathetic features. The PSH group comprised 349 reported cases, with 79.4% resulting from traumatic brain injury (TBI), 9.7% from hypoxia, and 5.4% from cerebrovascular accident. Although TBI is the dominant causative etiology, there was some suggestion that the true incidence of the condition is highest following cerebral hypoxia. In total, 31 different terms were identified for the condition. Although the most common term in the literature was dysautonomia, the consistency of sympathetic clinical features suggests that a more specific term should be used. The findings of this review suggest that PSH be adopted as a more clinically relevant and appropriate term. The review highlights major problems regarding conceptual definitions, diagnostic criteria, and nomenclature. Consensus on these issues is recommended as an essential basis for further research in the area.

Abstract
Introduction This case report describes an extremely rare combination of paroxysmal autonomic instability with dystonia and tuberculous meningitis. Paroxysmal autonomic instability with dystonia is normally associated with severe traumatic brain injury. Case presentation A 69-year-old man of Indonesian descent was initially suspected of having a community-acquired pneumonia, which was seen on chest X-ray and computed tomography of the chest. However, a bronchoscopy showed no abnormalities. He was treated with amoxicillin-clavulanic acid in combination with ciprofloxacin. However, nine days after admission he was disorientated and complained of headache. Neurological examination revealed no further abnormalities. A lumbar puncture revealed no evidence of meningitis. He was then transferred to our hospital. At that time, initial cultures of bronchial fluid for Mycobacterium tuberculosis turned positive, as well as polymerase chain reaction for Mycobacterium tuberculosis. Later, during his stay in our intensive care unit, he developed periods with hypertension, sinus tachycardia, excessive transpiration, decreased oxygen saturation with tachypnea, pink foamy sputum, and high fever. This constellation of symptoms was accompanied by dystonia in the first days. These episodes lasted approximately 30 minutes and improved after administration of morphine, benzodiazepines or clonidine. Magnetic resonance imaging showed an abnormal signal in the region of the hippocampus, thalamus and the anterior parts of the lentiform nucleus and caudate nucleus. Conclusions In patients with (tuberculous) meningitis and episodes of extreme hypertension and fever, paroxysmal autonomic instability with dystonia should be considered.

Abstract
PRIMARY OBJECTIVE To investigate disconnection theories postulated as the cause of dysautonomia following severe traumatic brain injury (TBI) through analysis of heart rate variability (HRV). METHODS AND PROCEDURES Data were collected on age-matched subjects with and without dysautonomia (eight subjects in each group) and 16 non-injured controls. Data included injury details, continuous electrocardiograph recordings and rehabilitation outcome. MAIN OUTCOMES AND RESULTS The TBI group revealed significant differences in HRV parameters both compared to controls and between dysautonomic and non-dysautonomic subjects. Additionally, HRV parameters for dysautonomic subjects showed evidence of an uncoupling of the normal relationship between heart rate and sympathetic/parasympathetic balance. HRV changes persisted for the dysautonomia group for a mean of 14 months post-injury. CONCLUSIONS Dysautonomic subjects revealed prolonged uncoupling of heart rate and HRV parameters compared to non-dysautonomic subjects and controls. These findings represent direct pathophysiological evidence supporting the disconnection theory postulated to produce dysautonomia following TBI.

Abstract
PRIMARY OBJECTIVE To document and critically evaluate the likely effectiveness of pharmacological treatments used in a sample of patients with Dysautonomia and to link these findings to previously published literature. RESEARCH DESIGN Retrospective case control chart review. METHODS AND PROCEDURES Data were collected on age, sex and GCS matched subjects with and without Dysautonomia (35 cases and 35 controls). Data included demographic and injury details, physiological parameters, medication usage, clinical progress and rehabilitation outcome. Descriptive analyses were undertaken to characterize the timing and frequency of CNS active medications. MAIN OUTCOMES AND RESULTS Dysautonomic patients were significantly more likely to receive neurologically active medications. A wide variety of drugs were utilised with the most frequent being morphine/midazolam and chlorpromazine. Cessation of morphine/midazolam produced significant increases in heart rate and respiratory rate but not temperature. Chlorpromazine may have modified respiratory rate responses, but not temperature or heart rate. CONCLUSIONS The features of Dysautonomia are similar to a number of conditions treated as medical emergencies. Despite this, no definitive treatment paradigm exists. The best available evidence is for morphine (especially intravenously), benzodiazepines, propanolol, bromocriptine and possibly intrathecal baclofen. Barriers to improving management include the lack of a standardized nomenclature, formal definition or accepted diagnostic test. Future research needs to be conducted to improve understanding of Dysautonomia with a view to minimizing disability.

Abstract
INTRODUCTION A 38-year-old man with severe head trauma complicated by paroxysmal severe intracranial pressure elevation associated with tachypnea, tachycardia, diaphoresis, and extensor posturing was diagnosed as suffering from paroxysmal autonomic instability with dystonia (PAID). These events were unresponsive to standard medical therapy, which included morphine, fentanyl, labetalol, lorazepam, metoprolol, and clonidine. METHODS A trial treatment with dexmedetomidine, a central acting alpha2-agonist, to control symptoms of PAID was initiated 12 days after injury. PAID-related events subsided during the 72-h infusion protocol of 0.2-0.7 mcg/kg/h. No further events were noted after termination of the 72-h infusion. CONCLUSIONS Dexmedetomidine may be a novel pharmacologic agent to aid in abrogating PAID.

Abstract
OBJECTIVE To assess the incidence and associations of paroxysmal sympathetic hyperactivity (PSH) among febrile patients in the neurological intensive care unit (NICU). METHODS Prospective data collection of consecutive patients admitted to an academic NICU for >48 hours. Fever was defined as body temperature >38.3 degrees C (101.0 degrees F) on at least one measurement for two consecutive days. PSH was defined by the transient presence of four of the following six criteria: fever, tachycardia, hypertension, tachypnea, excessive diaphoresis and extensor posturing or severe dystonia in the absence of other potential causes for these clinical signs. Methods: Ninety-three patients were included. Traumatic brain injury (TBI) was the primary diagnosis in 43 patients (46%). PSH were diagnosed in 17 patients (18%). It occurred in 14/43 patients (33%) with TBI but only 3/50 patients (6%) with other primary disorders (p = 0.01). Patients with PSH were younger (mean age: 35 +/- 14 versus 51 +/- 18 years old in the rest of the population) (p = 0.01), although the difference did not reach statistical significance when only TBI patients were included in the analysis (mean age: 35 +/- 15 years old in TBI patients with PSH versus 46 +/- 19 years old in TBI patients without PSH; p = 0.07). Duration of fever in patients with PSH (mean: 10.5 +/- 7 days; median: 9 days) was significantly longer than in the rest of the population (mean: 5.1 +/- 3 days) (p<0.001); the difference remained significant when the analysis was restricted to TBI patients (p = 0.001). CONCLUSION Episodes of PSH occur in one-third of TBI patients but are rare in other acute neurological conditions. They are more frequent in younger patients and are associated with prolonged duration of fever.

Abstract
BACKGROUND Cardiac uncoupling and reduced heart rate (HR) variability are associated with increased mortality after severe traumatic brain injury (TBI). Recent data has shown beta-blocker (betaB) exposure is associated with improved survival in this patient population. The purpose of the present study was to evaluate the effect of betaB exposure on the mortality risk of patients with severe TBI and early cardiac uncoupling. METHODS From December 2000 to October 2005, 4,116 patients were admitted to the trauma intensive care unit. Four hundred forty-six patients (12%) had head Abbreviated Injury Scale score >/= 5 without neck injury and had continuous HR data for the first 24 hours. One hundred forty-one patients (29%) received betaB. Cardiac uncoupling was calculated as the percent of time that 5-minute HR standard deviation was between 0.3 bpm and 0.6 bpm on postinjury day 1. RESULTS A relationship between betaB and survival was observed when the population was considered irrespective of length of stay or betaB start time (p < 0.001). Cardiac uncoupling appears to stratify patients into groups who might receive additional benefit from betaB, and identifies patients with increasing mortality. However, the association of betaB with survival was attenuated when analyses accounted for selection bias in betaB administration. CONCLUSIONS betaB exposure was associated with reduced mortality among patients with severe TBI. Though loss of HR variability has previously been associated with an increase in mortality, betaB exposure appears to be associated with increased survival across all stratifications of cardiac uncoupling.

Abstract
BACKGROUND Beta-blocker use in elective noncardiac surgery has been associated with a reduction in mortality and cardiovascular complications. Traumatic brain injury (TBI) is often associated with a hyperadrenergic state. We hypothesized that adrenergic blockade would confer improved survival among TBI patients. METHODS Retrospective review of the Trauma Registry of the American College of Surgeons database at a Level I trauma center was conducted. All trauma patients admitted from January 2004 to March 2005 with head Abbreviated Injury Scale score of 3 or greater were evaluated. Patients with length of stay <4 or >30 days were excluded. Beta-blocker exposure was defined as receiving beta-blockers for 2 or more consecutive days. RESULTS In all, 420 patients met inclusion criteria: 174 patients exposed to beta-blockers [BB(+)] and 246 not exposed [BB(-)]. Mean age in BB(+) group was 50 years and 36 years in BB(-) group (p < 0.001). Mean Injury Severity Score was 33.6 for BB(+) group and 30.8 for BB(-) group (p = 0.01). Predicted survival (by Trauma and Injury Severity Score) for BB(+) group was 59.1% compared with 70.3% for BB(-) group (p < 0.001). Observed mortality for BB(+) group was 5.1%, 10.8% for BB(-) group (p = 0.036). Adjusted incidence rate ratio of mortality among those exposed to beta-blockers compared with those not exposed was 0.29 (95% confidence interval). CONCLUSIONS Beta-blocker exposure was associated with a significant reduction in mortality in patients with severe TBI. This reduction in mortality is even more impressive, considering that the BB(+) group was older, more severely injured, and had lower predicted survival.

Abstract
BACKGROUND Dysautonomic crises represent a relatively unknown complication in patients with severe traumatic brain injury (TBI). Few studies have been undertaken of their pathophysiology and prognostic repercussions. We studied the prevalence of dysautonomic crises after TBI, their radiologic substrate, influence on the clinical course in the intensive care unit (ICU), and effect on neurologic recovery. METHODS A case-control study involving 11 patients with dysautonomic crises admitted with TBI during a span of 1 year and 26 patients admitted with TBI but no crises during the first 3 months of the same year. The initial severity was assessed from Apache II, Glasgow Coma Scale (GCS) scores, and computed tomography (CT) during the first 24 hours. Complications were assessed by the duration of ICU stay, days on mechanical ventilation, need for tracheotomy, and number of infectious complications. Neurologic recovery was assessed with the GCS at discharge from the ICU and with the Glasgow Outcome Scale 12 months later. RESULTS Both groups were similar at admission. The prevalence of dysautonomic crises was 9.3%. Patients with dysautonomic crises had more focal lesions on cranial CT than patients without crises, a significantly longer ICU stay, and a tendency to have a worse level of consciousness at discharge from the ICU but not 12 months later. CONCLUSIONS Almost 10% of patients with severe TBI have dysautonomic crises during their ICU stay. Patients with dysautonomia were more likely to have focal intraparenchymal lesions, and crises were associated with greater morbidity and a longer ICU stay. Dysautonomic crises determined a worse short-term neurologic recovery.
