A 54-year-old man with a 3-week history of orthostatic headache and acute on chronic subdural hematoma presented with imaging findings suggestive of spontaneous intracranial hypotension. Three myelograms were negative for leak, and nontargeted epidural blood patches did not result in symptom relief. A cerebrospinal fluid leak study using In-DTPA with SPECT/CT demonstrated a focal area of asymmetric activity at the left C2 nerve root. A left C2 root tie-off, targeted epidural blood patch, and Dura seal glue resulted in resolution of patient symptomatology highlighting the importance of fused SPECT/CT images in detection of an occult cerebral spinal fluid leak...

Neurogenic orthostatic hypotension (nOH) is common in patients with neurodegenerative disorders such as Parkinson's disease, multiple system atrophy, pure autonomic failure, dementia with Lewy bodies, and peripheral neuropathies including amyloid or diabetic neuropathy. Due to the frequency of nOH in the aging population, clinicians need to be well informed about its diagnosis and management. To date, studies of nOH have used different outcome measures and various methods of diagnosis, thereby preventing the generation of evidence-based guidelines to direct clinicians towards 'best practices' when treating patients with nOH and associated supine hypertension...

Vibrio mimicus, although named for having many of the same virulent factors as Vibrio cholera, is a rare cause of significant gastrointestinal illness. Like many of the Vibrio species, the strongest risk factor for V. mimicus infection is seafood consumption. After consuming crabs, a 64-year-old male presented with a three day history of voluminous, non-bloody, water diarrhea. The severity of the diarrhea caused the patient to have orthostatic hypotension and acute kidney injury, which improved with fluid resuscitation...

A 62-year-old woman presented with paresthesia of limbs, gait disturbance, urinary retention and constipation following upper respiratory infection. Neurological examination revealed gait disturbance due to loss of position sense in her extremities with intact muscle power, and autonomic failure represented by orthostatic hypotension, constipation and autonomic bladder. Cerebrospinal fluid analysis showed normal cell counts with elevated protein levels. Nerve conduction study showed sensory nerve impairment with almost normal motor nerve conduction in her upper and lower extremities...

A continuous-flow left ventricular assist device (CF-LVAD) benefits patients with advanced heart failure as a bridge to cardiac transplantation. However, unanticipated complications may occur. We report a patient with end-stage heart failure and longstanding diabetes who experienced functionally debilitating orthostatic hypotension from autonomic insufficiency after CF-LVAD implantation. This case demonstrates a role for comprehensive autonomic function testing in the workup of orthostatic hypotension after LVAD implantation...

Introduction: Tilt tables enable early mobilization of patients by providing verticalization. But there is a high risk of orthostatic hypotension provoked by verticalization, especially after neurological diseases such as spinal cord injury. Robot-assisted tilt tables might be an alternative as they add passive robotic leg exercise (PE) that can be enhanced with functional electrical stimulation (FES) to the verticalization, thus reducing the risk of orthostatic hypotension. We hypothesized that the influence of PE on the cardiovascular system during verticalization (i...

INTRODUCTION: Lower body mass index (BMI) is associated with orthostatic hypotension (OH) in the general population, especially in the elderly; however, no studies have addressed this issue in Parkinson's disease (PD). METHODS: We investigated the results of the head-up tilt test and BMI of patients with PD, and evaluated whether BMI is related to orthostatic systolic blood pressure (SBP) change during the head-up tilt test. PD patients were divided into male and female groups, and further divided into middle-aged (age<65years) and elderly (age≥65years) subgroups in each sex...

BACKGROUND: falls are a common cause of morbidity and mortality in older people. Orthostatic hypotension (OH) is considered an important risk factor for falls, but longitudinal studies have failed to show a clear association. This disparity may be because conventional methods of measuring blood pressure (BP) changes are too imprecise and/or the diagnostic criteria for OH are inappropriate. Over recent years, beat-to-beat BP monitoring techniques, which enabled accurate measurement of vasodepression, have become widely used and in 2011 the American Academy of Neurology produced revised diagnostic criteria for OH...

REVIEW
Italo Biaggioni
Primary neurodegenerative autonomic disorders are characterized clinically by loss of autonomic regulation of blood pressure. The clinical picture is dominated by orthostatic hypotension, but supine hypertension is also a significant problem. Autonomic failure can result from impairment of central autonomic pathways (multiple system atrophy) or neurodegeneration of peripheral postganglionic autonomic fibers (pure autonomic failure, Parkinson's disease). Pharmacologic probes such as the ganglionic blocker trimethaphan can help us in the understanding of the underlying pathophysiology and diagnosis of these disorders...

This Letter aims to create a fuzzy logic-based assistive prevention tool for falls, based on accessible sensory technology, such as smartwatch, resulting in monitoring of the risk factors of falls caused by orthostatic hypotension (OH); a drop in systolic blood pressure (DSBP) >20 mmHg due to postural changes. Epidemiological studies have shown that OH is a high risk factor for falls and has a strong impact in quality of life (QoL) of the elderly's, especially for some cases such as Parkinsonians. Based on smartwatch data, it is explored here how statistical features of heart rate variability (HRV) can lead to DSBP prediction and estimation of the risk of fall...

Autonomic dysfunction in multiple system atrophy (MSA) comprises cardinal symptoms of orthostatic hypotension (OH) and urinary incontinence. Additionally, cardiovagal and sudomotor abnormalities can be present. Previous studies compared hand skin temperature and its response to cooling in subjects with probable MSA and Parkinson's disease (PD). Significant differences were found indicating that disturbed thermoregulation belongs to MSA autonomic features and could be helpful in differentiation of MSA from PD...

OBJECTIVE: Our objectives were to investigate the relationship between orthostatic hypotension (OH) and muscle strength versus time to successful rehabilitation within elderly hip fracture patients. DESIGN: A prospective observational cohort study. Handgrip strength was measured at the day of admission and OH as soon as possible after surgery. Cox proportional hazard modelling was used to investigate the relationship between OH, or handgrip strength (kg) and time to successful rehabilitation, expressed as hazard ratios (HR)...

BACKGROUND: The clinical characteristics of Takayasu arteritis (TAK) developing in individuals older than 40 years (TAK >40) are little-known. METHOD: We retrospectively analyzed 43 patients with TAK treated at three hospitals in Japan from April 2000 to March 2016. From medical records we collected baseline variables at diagnosis including clinical symptoms, laboratory data, and subsequent relapses. We compared these indices in the patients with TAK onset at >40 years of age (TAK >40) to those with TAK onset ≤40 years (TAK ≤40)...

Autonomic dysfunction in diabetes is serious but often underestimated. The purpose of this study was to evaluate hemodynamics within the important initial phase just after standing, which cannot be evaluated by conventional instruments for orthostatic hypotension. Earlobe blood flow (EBF), which indirectly reflects the blood pressure response on standing, was evaluated using a mini laser Doppler flowmeter during standing from the sitting position in 58 healthy controls and 56 diabetic patients categorized as without (11), mild (27), and advanced diabetic polyneuropathy (18)...

Postural tachycardia syndrome is defined by a heart rate increment of 40 beats/minute (bpm) (or a heart rate that exceeds 125 bpm) within 10 minutes of change from the supine position to an upright position in the absence of obvious orthostatic hypotension. There are multiple pathophysiological mechanisms that underlie postural tachycardia syndrome, including peripheral denervation, β-receptor supersensitivity, hypovolaemia, and impaired muscle pump. Some children afflicted with postural orthostatic tachycardia syndrome and hypovolaemic dysregulation have been found to have perturbed renin-angiotensin-aldosterone profile, disturbed vascular endothelial function, and abnormal vasodilation...

Nutcracker syndrome (NCS) is symptomatic unilateral renal venous hypertension due to compression of the left renal vein between the superior mesenteric artery and aorta (anterior NCS) or between the aorta and spine (posterior NCS). The left ovarian or spermatic vein empties into the left renal vein and is an additional site of venostasis in about half the cases of NCS. The presenting symptom of NCS in about half the cases is atypical left flank pain suggesting a disorder of the lower ribs or thoracolumbar spinal junction, particularly as the pain worsens with standing and increased lumbar lordosis...

The aim of the present review is to consider the clinical relevance of individualized blood pressure (BP) goal under treatment in hypertensive patients according to their age, comorbidities or established cardiovascular (CV) disease. Evidence from large-scale randomized trials to support a lower BP goal, as initially recommended by guidelines in high-risk hypertensive patients, were lacking. Recently, the randomized intervention SPRINT trial studied two treatment targets for systolic BP (120mm Hg versus 140mm Hg in the intensive and standard treatment group, respectively) among high-risk hypertensive patients, without diabetes and without a history of prior stroke...

In a prospective study, we recently discovered 8 clinical predictors of dementia in Parkinson's disease. Here, we validate these dementia predictors using two additional prospective cohorts (n = 134). After a 3.6-year follow-up, 35/134 developed dementia (7.2% per year). When confirming individual variables, 5/8 were significantly associated with dementia in the validation cohort. These included age, male sex, baseline RBD, orthostatic hypotension, and MCI. Bilateral onset, hallucinations and falls/freezing did not significantly predict dementia; however, point estimates of OR were all >1...
