OBJECTIVE: Our aim was to look for a probable relationship between cerebral vasomotor
reactivity (VMR) and orthostatic hypotension (OH) in Parkinson's disease (PD). MATERIALS …

Background. Orthostatic hypotension (OH) is an important nonmotor manifestation of
Parkinson's disease (PD). Changes in cerebrovascular reactivity may contribute to this …

Orthostatic hypotension (OH) is one of the many autonomic disturbances observed in
Parkinson's disease (PD). It has been debated whether an additional impairment of cerebral …

Parkinson's disease (PD), multiple system atrophy (MSA) and pure autonomic failure (PAF)
are neurodegenerative disorders frequently associated with orthostatic hypotension and …

Purpose The ability of a blood vessel to change diameter in response to a change in carbon
dioxide concentration is often referred to as vasomotor reactivity. This study aimed to …

Patients with Parkinson's disease (PD) often present with orthostatic hypotension (OH) as a
result of the dysautonomia associated with the disease or as a side effect of the …

Orthostatic hypotension (OH) is a frequent nonmotor feature of Parkinson's disease (PD),
and its occurrence has been associated with cognitive impairment. The underlying …

BACKGROUND AND PURPOSE: Disturbance of the autonomic nervous system (ANS) is
frequently encountered in Parkinson's disease (PD). In this study, we examined changes in …

Background: Clinical symptoms of Parkinson's disease (PD) include not only motor distress,
but also autonomic dysfunction. Objective: To study the characteristics of subclinical …

Background: The frequent orthostatic intolerance in PD could be the consequences of
cardiovascular-autonomic failure and/or damaged cerebral autoregulation Objective: The …
