Partial pharmacologic blockade shows sympathetic connection between blood pressure and cerebral blood flow velocity fluctuations [PDF]

, 2016
Cerebral autoregulation (CA) dampens transfer of blood pressure (BP)-fluctuations onto cerebral blood flow velocity (CBFV). Thus, CBFV-oscillations precede BP-oscillations.

Integrated analysis of droxidopa trials for neurogenic orthostatic hypotension

BMC Neurology, 2017
Background Droxidopa, a prodrug of norepinephrine, was approved for treatment of neurogenic orthostatic hypotension (nOH) due to primary autonomic disorders based on 3 randomized double-blind studies.

Case report: Epidural blood patches are effective in treating intracranial hypotension due to a subarachnoid-pleural fistula

Frontiers in Surgery, 2022
BackgroundIntracranial hypotension (IH) is usually associated with cerebrospinal fluid (CSF) leakage and/or CSF hypotension, and epidural blood patch (EBP) therapy has been proven to be effective for treating spontaneous IH and post-dural puncture ...

Reduced brainstem functional connectivity in patients with peripheral autonomic failure

NeuroImage: Clinical, 2019
Autonomic homeostasis is dependent upon several brainstem nuclei, as well as several cortical and subcortical structures. Together, these sites make up, in part, the central autonomic network.

Prospects for Droxidopa in Neurogenic Orthostatic Hypotension [PDF]

Hypertension, 2015
See related article, pp 101–107 Neurogenic orthostatic hypotension (nOH) is a debilitating disorder defined by a sustained decrease in systolic blood pressure of 20 mm Hg or in diastolic blood pressure of 10 mm Hg within 3 minutes of head-up tilt or standing.1 The disorder is associated with attenuated increases in plasma norepinephrine and peripheral

Cardiac 123I-MIBG Scintigraphy in Neurodegenerative Parkinson Syndromes: Performance and Pitfalls in Clinical Practice [PDF]

, 2019
Purpose: Cardiac [I-123]metaiodobenzylguanidine scintigraphy (123I-MIBG), reflecting postganglionic cardiac autonomic denervation, is proposed for early detection of Parkinson's disease (PD; reduced tracer uptake) and separation from Multiple System ...

The absence of orthostatic heart rate increase is associated with cognitive impairment in Parkinson's disease.

PLoS ONE, 2020
Orthostatic hypotension (OH) frequently accompanies autonomic dysfunction and is an important risk factor for cognitive impairment in Parkinson's disease (PD).

Pyridostigmine Treatment Trial in Neurogenic Orthostatic Hypotension [PDF]

Archives of Neurology, 2006
Midodrine hydrochloride is the only drug demonstrated in a placebo-controlled treatment trial to improve orthostatic hypotension (OH) but it significantly worsens supine hypertension. By enhancing ganglionic transmission, pyridostigmine bromide can potentially ameliorate OH without worsening supine hypertension.To evaluate the efficacy of a single 60 ...

Reliability of orthostatic beat-to-beat blood pressure tests: implications for population and clinical studies [PDF]

, 2017
Objective: To assess the test–retest reliability of orthostatic beat-to-beat blood pressure responses to active standing and related clinical definitions of orthostatic hypotension. Methods: A random sample of community-dwelling older adults from the pan-
