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

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

Pyridostigmine Treatment Trial in Neurogenic Orthostatic Hypotension [PDF]

open access: yesArchives 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 ...

Natural history of falls in an incident cohort of Parkinson’s disease: early evolution, risk and protective features [PDF]

open access: yes, 2017
The natural history of falls in early Parkinson’s disease (PD) is poorly understood despite the profound effect of falls on outcome. The primary aim of this study was to describe the natural history of falls, and characterise fallers over 54 months in 99

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

open access: yes, 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 ...

Treatment of Orthostatic Hypotension Due to Autonomic Dysfunction (Neurogenic Orthostatic Hypotension) in a Patient with Cardiovascular Disease and Parkinson's Disease

open access: yesCardiology and Therapy, 2019
Introduction The prevalence of neurogenic orthostatic hypotension (nOH) increases with age and is associated with autonomic failure in neurodegenerative diseases (e.g., Parkinson's disease).
