is an integral component of Parkinson's disease (PD), and orthostatic hypotension (OH) can be an important clue to the underlying cardiovascular autonomic failure
According to a new LSU Pennington Biomedical Research Center USA study, a novel biomarker might give us answers necessary to create a diagnostic tool for hypoglycemia-associated autonomic failure

Neurogenic OH (NOH), a commonly overlooked subtype of OH, is associated with nervous system impairment, and is predominantly seen in neurodegenerative disorders such as PD, multiple system atrophy (MSA), and pure autonomic failure
A systematic review of autonomic dysfunction in [alpha]-synucleinopathies revealed that cardiovascular autonomic failure
has a significant impact on daily activities and QoL.
The Ewing score (ES) ranging from 0 (normal) to 5 (severe autonomic failure
) represents the sum of the responses to the different tests.
Practical bedside investigation of diabetic autonomic failure
. In: Autonomic failure
Other important examinations that can be done in order to understand the complex differential diagnosis of this syndrome include total sweating test to recognize areas of anhidrosis, cardiovascular reflex tests to recognize the presence of autonomic failure
, microneurography from the peroneal nerve to record muscle sympathetic nerve activity and skin sympathetic nerve activity in the same innervation field, and a skin biopsy.

who found length-dependent somatic and autonomic small fiber damage, both in patients with PD and in those with pure autonomic failure
Other processes are described in the literature, including pure autonomic failure
(PAF) and familial dysautonomia, which may also result in orthostatic hypotension.
Probable MSA also specifies that the patient show either autonomic failure
involving urinary incontinence--this includes erectile dysfunction in men--or, if autonomic failure
is absent, orthostatic hypotension within 3 minutes of standing by at least 30 mm Hg systolic pressure or 15 mm Hg diastolic pressure.
