  • Wired for Threat: Clinical Features of Nervous System Dysregulation in 80 Children. Pediatric neurology Elbers, J., Jaradeh, S., Yeh, A. M., Golianu, B. 2018

    Abstract

    BACKGROUND: The negative effect of perceived stress on health has become a cultural epidemic. Despite many health implications, the clinical impact of stress on the nervous system is not well understood. This case series describes the symptom profiles of 80 children with nervous system dysregulation attributed to maladaptive neuroendocrine responses to stress.METHODS: We reviewed of 80 children with nervous system dysregulation identified from a single, tertiary care pediatric neurology clinic. Included patients were between five and 17 years of age, with unexplained medical symptoms lasting three months or longer affecting at least four of six neurological domains: (1) somatization, (2) executive function, (3) autonomic function, (4) digestion, (5) sleep, and (6) emotional regulation. Medical symptoms, diagnoses, and detailed social histories were collected.RESULTS: Of 80 children, 57 were female (71%), 57 were Caucasian (71%), with median age of 14 years. Symptoms had a mean duration of 32 months, and included: 100% somatic symptoms, 100% emotional dysregulation, 92.5% disrupted sleep, 82.5% autonomic dysregulation, 75% executive dysfunction, and 66% digestive problems. Overall, 94% reported chronic or traumatic stressors; adverse childhood experiences were present in 65%.CONCLUSIONS: Perceived stress impacts many functions of the neuroendocrine system through experience-dependent plasticity, resulting in a constellation of symptoms and functional impairments we describe as nervous system dysregulation. The pathophysiology of these symptoms involves dysregulation of subcortical, hormonal, and autonomic circuits, which remain largely untested. Recognition and understanding of maladaptive neurophysiology in stress-related symptoms has important implications for diagnosis, treatment, and advances in health research.

  • The clinical utility of qualitative electroencephalography during tilt table testing - A retrospective study CLINICAL NEUROPHYSIOLOGY Muppidi, S., Razavi, B., Miglis, M. G., Jaradeh, S. 2018; 129 (4): 783?86

    Abstract

    To assess electroencephalography (EEG) changes during tilt table testing in syncope and other orthostatic syndromes.We retrospectively reviewed consecutive tilt table studies with simultaneous EEG from April 2014 to May 2016 at our center. All patients had video EEG during tilt table. All patients had at least 10?min of head up tilt unless they had syncope or did not tolerate the study. Video EEG was interpreted by epileptologists.Eighty-seven patients met the inclusion criteria. Mean age was 45?years, and 55 were women. Seven patients (?8%) had syncope during tilt table, 11 patients (?12%) had significant neurogenic orthostatic hypotension and a separate group of 11 patients (?12%) had significant orthostatic tachycardia. Valsalva responses were abnormal in 7 of the 11 patients with orthostatic hypotension, suggesting an underlying neurogenic orthostatic hypotension. Visually discernable EEG changes were seen in only 3 patients (?43%) who had syncope and in 1 patient (?9%) with orthostatic tachycardia.Qualitative EEG analysis based on visual inspection during tilt table study revealed abnormalities in less than half the patients with syncope and a very small fraction with orthostatic tachycardia.Routine qualitative EEG recording might not be clinically useful during tilt table studies.

  • A case series of REM sleep behavior disorder in pure autonomic failure CLINICAL AUTONOMIC RESEARCH Miglis, M. G., Muppidi, S., During, E., Jaradeh, S. 2017; 27 (1): 41-44

    Abstract

    Data on the prevalence of RBD in patients with PAF are limited, with discrepancies in the literature regarding prevalence. We aimed to provide further data on this association with a series of eight patients with PAF.We reviewed the electronic medical records of all patients seen at the Stanford neurology clinics from 2012 to 2016 who were given a provisional diagnosis of PAF (343 patients), and further screened by procedure codes to identify those patients who underwent both attended video-polysomonography and autonomic testing (18 patients), and met strict exclusionary criteria (8 patients).The mean age of our patients was 69 years, and 63 % were women. The mean duration of autonomic symptoms was 11.2 years, and the mean duration of dream enactment was 3.75 years. All patients demonstrated evidence of adrenergic failure on autonomic testing. Five out of 8 (63 %) met diagnostic criteria for RBD, confirmed on vPSG.Our series supports the concept that RBD in PAF may be more common than previously reported, and that the presence of RBD suggests brainstem involvement in some cases of PAF. In addition, the timing of RBD symptoms relative to the emergence of autonomic symptoms may be useful to help distinguish these conditions.

  • Pediatric Anti-ganglionic Antibody Positive Autonomic Neuropathy: Clinical Presentation and Response to Treatment PEDIATRIC NEUROLOGY Tiongson, E., Pimentel, N., Ramos-Platt, L., Jaradeh, S. 2016; 64: 72-76

    Abstract

    Autoimmune autonomic neuropathy is rare in children. There are few pediatric reports documenting anti-ganglionic antibodies.We present two children with anti-ganglionic antibody positive autonomic neuropathy, including their presentation, results of testing, and treatment course.Both children had delayed diagnoses because of the presence of vague autonomic symptoms. Treatment with multiple immunotherapies appears to bring at least a partial response and can be monitored with anti-ganglionic antibody titers.Our findings contribute to the sparse literature in pediatric autoimmune autonomic neuropathy and highlight the need for additional studies to create diagnostic criteria and define optimal treatment regimens.

  • Sleep disorders in patients with postural tachycardia syndrome. Clinical autonomic research Miglis, M. G., Muppidi, S., Feakins, C., Fong, L., Prieto, T., Jaradeh, S. 2016; 26 (1): 67-73

    Abstract

    Patients with postural tachycardia syndrome (POTS) often describe symptoms of fatigue, sleepiness, and lack of refreshing sleep. We aimed to provide further objective measures of sleep in patients with POTS.POTS patients (n = 18) were selected based on autonomic testing and evaluation at our center. Controls (n = 16) of similar age, gender, and BMI were selected from new patients referred to the Stanford Sleep Disorders Clinic for any sleep-related complaint. All patients underwent polysomnography and completed several sleep questionnaires and a 2-week sleep diary.POTS patients and control subjects were of similar age (27 ± 10.2 vs. 29 ± 5.4 years, p = 0.92) and Body Mass Index (21 ± 3.8 vs. 24 ± 4.1, p = 0.14). The majority of subjects in both groups were females (72 % POTS vs. 81 % controls). POTS patients scored higher on subjective fatigue scales but not sleepiness scales. POTS patients scored in the normal range on the BDI and the "evening" category on the MEQ. Their sleep diaries were not different from controls. With the exception of mild OSA, slightly reduced %REM and prolonged REM latency, their PSG data were normal and no different from controls.It is unlikely that the sleep-related complaints of POTS patients are the result of a primary sleep disorder unique to POTS. We propose that a combination of factors such as body fatigue, chronic pain, and other somatic symptoms common in POTS patients might be the underlying reason for sleep-related symptoms in POTS.

  • Cumulative Brain Injury from Motor Vehicle-Induced Whole-Body Vibration and Prevention by Human Apolipoprotein A-I Molecule Mimetic (4F) Peptide (an Apo A-I Mimetic) JOURNAL OF STROKE & CEREBROVASCULAR DISEASES Yan, J., Zhang, L., Agresti, M., Yan, Y., LoGiudice, J., Sanger, J. R., Matloub, H. S., Pritchard, K. A., Jaradeh, S. S., Havlik, R. 2015; 24 (12): 2759-2773

    Abstract

    Insidious cumulative brain injury from motor vehicle-induced whole-body vibration (MV-WBV) has not yet been studied. The objective of the present study is to validate whether whole-body vibration for long periods causes cumulative brain injury and impairment of the cerebral function. We also explored a preventive method for MV-WBV injury.A study simulating whole-body vibration was conducted in 72 male Sprague-Dawley rats divided into 9 groups (N = 8): (1) 2-week normal control; (2) 2-week sham control (in the tube without vibration); (3) 2-week vibration (exposed to whole-body vibration at 30 Hz and .5 G acceleration for 4 hours/day, 5 days/week for 2 weeks; vibration parameters in the present study are similar to the most common driving conditions); (4) 4-week sham control; (5) 4-week vibration; (6) 4-week vibration with human apolipoprotein A-I molecule mimetic (4F)-preconditioning; (7) 8-week sham control; (8) 8-week vibration; and (9) 8-week 4F-preconditioning group. All the rats were evaluated by behavioral, physiological, and histological studies of the brain.Brain injury from vibration is a cumulative process starting with cerebral vasoconstriction, squeezing of the endothelial cells, increased free radicals, decreased nitric oxide, insufficient blood supply to the brain, and repeated reperfusion injury to brain neurons. In the 8-week vibration group, which indicated chronic brain edema, shrunken neuron numbers increased and whole neurons atrophied, which strongly correlated with neural functional impairment. There was no prominent brain neuronal injury in the 4F groups.The present study demonstrated cumulative brain injury from MV-WBV and validated the preventive effects of 4F preconditioning.

  • Prevalence of REM sleep behavior disorder in multiple system atrophy: a multicenter study and meta-analysis CLINICAL AUTONOMIC RESEARCH Palma, J., Fernandez-Cordon, C., Coon, E. A., Low, P. A., Miglis, M. G., Jaradeh, S., Bhaumik, A. K., Dayalu, P., Urrestarazu, E., Iriarte, J., Biaggioni, I., Kaufmann, H. 2015; 25 (1): 69-75

    Abstract

    Rapid eye movement (REM) sleep behavior disorder (RBD) is a parasomnia frequently affecting patients with synucleinopathies, but its exact prevalence in multiple system atrophy (MSA) is unclear. Whether questionnaires alone are sufficient to diagnose RBD is also unknown.We performed a cross-sectional study of patients with probable MSA from six academic centers in the US and Europe. RBD was ascertained clinically and with polysomnography; we also performed a meta-analysis according to PRISMA guidelines for studies published before September 2014 that reported the prevalence of RBD in MSA. A random-effects model was constructed using weighted prevalence proportions. Only articles in English were included. Studies were classified into those that ascertained the presence of RBD in MSA clinically and with polysomnography. Case reports or case series (?5 patients) were not included.Forty-two patients completed questionnaires and underwent polysomnography. Of those, 32 (76.1 %) had clinically suspected RBD and 34 (81 %) had polysomnography-confirmed RBD. Two patients reported no symptoms of RBD but had polysomnography-confirmed RBD. The primary search strategy yielded 374 articles of which 12 met the inclusion criteria. The summary prevalence of clinically suspected RBD was 73 % (95 % CI, 62-84 %) in a combined sample of 324 MSA patients. The summary prevalence of polysomnography-confirmed RBD was 88 % (95 % CI, 79-94 %) in a combined sample of 217 MSA patients.Polysomnography-confirmed RBD is present in up to 88 % of patients with MSA. RBD was present in some patients that reported no symptoms. More than half of MSA patients report symptoms of RBD before the onset of motor deficits.

  • Surface-evoked laryngeal sensory action potential evaluation in neurogenic chronic cough. Journal of voice Bock, J. M., Koszewski, I. J., Blumin, J. H., Toohill, R. J., Merati, A. L., Prieto, T. E., Jaradeh, S. S. 2014; 28 (5): 624-630

    Abstract

    Neurogenic chronic cough is currently a diagnosis of exclusion. We hypothesized that surface-evoked laryngeal sensory action potential (SELSAP) testing could be used to help establish a diagnosis of laryngeal sensory neuropathy as a cause of chronic cough, based on altered SELSAP waveform morphology.Retrospective cohort study.Laryngeal electromyographic (EMG) data including SELSAP waveform testing from patients with chronic cough were directly compared with a control population without significant laryngeal symptoms, and statistical analysis of unilateral and bilateral neuropathy injury subgroups was performed.Thirty patients with a chief complaint of chronic cough underwent laryngeal EMG testing since January 2000 with needle EMG and surface nerve conduction studies. SELSAP waveform analysis of unilateral and bilateral laryngeal neuropathy demonstrated significantly lowered median SELSAP peak amplitude compared with controls (P < 0.01).Patients with suspected neurogenic chronic cough demonstrate statistically significant alterations in SELSAP waveform that can support a diagnosis of laryngeal sensory neuropathy.

  • The Correlation between Calcium Intensity and Histopathological Changes in Brachial Plexus Nerve Injuries JOURNAL OF RECONSTRUCTIVE MICROSURGERY Davis, J., O'Connor, E., Zhang, L., Agresti, M., Matloub, H. S., Sanger, J., Jaradeh, S. S., Yan, J. 2013; 29 (7)

    Abstract

    Background After nerve injury, an influx of calcium exceeds the homeostatic capacity, which damages peripheral nerves. Previous studies identified that following nerve crush, function improves as calcium levels normalize.Methods Electrophysiological analysis was performed to measure the compound muscle action potential of 15 patients' damaged nerves. These samples were evaluated for calcium level and also stained with a Luxol fast blue and neurofilament antibodies to evaluate the myelin sheath and neurofilaments of the nerves. Based on the Sunderland scale, we identified three exclusive types of peripheral nerve injury groups.Results There was a correlation between histopathological damage and calcium levels of 0.81 (p < 0.005). The average relative fluorescence units (RFUs) was 235.28 ± 19, which corresponds to 5.3 × 10-7 M of calcium, five times the normal value.Conclusion Our study shows promising clinical implications via faster pathology results by the RFU technique. This approach of calcium staining, though still in clinical trials, offers significant clinical application, allowing physicians to get the clinically diagnostic nerve injury degree faster and will also facilitate better strategies for further treatment or future surgeries.
