Bed rest studies of the past 20 years are reviewed. Head-down bed rest (HDBR) has proved
its usefulness as a reliable simulation model for the most physiological effects of spaceflight. …

Purpose Patients suffering from cardiovascular autonomic failure often develop neurogenic
supine hypertension (nSH), ie, high blood pressure (BP) in the supine position, which falls in …

Patients with cardiovascular disease show autonomic dysfunction, including sympathetic
activation and vagal withdrawal, which leads to fatal events. This review aims to place …

Several studies have confirmed the α-synuclein real-time quaking-induced conversion (RT-QuIC)
assay to have high sensitivity and specificity for Parkinson’s disease. However, …

This paper summarizes what has been learned from studies of the effects of artificial gravity
generated by centrifugation in actual and simulated weightless conditions. The experience of …

The Movement Disorder Society established a task force to review rating scales for the
assessment of tremor. Screening instruments used in identifying patients with tremor were also …

Background and Purpose—Asymptomatic microembolic signals (MES) can be demonstrated
in patients with cerebral ischemia using transcranial Doppler (TCD) ultrasonographic …

Intracranial pressure (ICP) is the pressure within the cranium. ICP rise compresses brain
vessels and reduces cerebral blood delivery. Massive ICP rise leads to cerebral ischemia, but it …

Purpose To determine the change in intraocular pressure (IOP) due to postural changes in
young healthy volunteers. Materials and Methods Intraocular pressure was measured using a …

Background and Purpose— The arterial baroreflex is an important determinant of the short-term
regulation of blood pressure and cardiovascular variability. The purpose of our study …
