Assessment

Primary outcomes

Can the transfer function from deep brain stimulation to blood pressure be described and identified?

Key secondary outcomes

(1) Can a control center program be designed that allows the blood pressure servo system, which compensates for blood pressure drops, to operate most stably and rapidly?
(2) Can the degree of blood pressure drop upon standing be improved depending on the presence or absence of stimulation?
(3) Is there a correlation between the responsiveness of blood pressure to stimulation and the stimulation site identified by MRI?
(4) Is there a correlation with the degree of blood pressure drop while seated?
(5) Is blood pressure reactivity associated with the patient's clinical background?

Parkinson disease, which most commonly affects middle-aged and older adults, is frequently associated with orthostatic hypotension. There is currently no treatment for drug-resistant orthostatic hypotension, and patients often become bedridden in the late stages of the disease.
Deep brain stimulation is effective against the primary motor symptoms of Parkinson disease, such as tremor, bradykinesia, and rigidity; however, its effects on blood pressure have not been fully elucidated. Therefore, we investigated the blood pressure response to deep brain stimulation.
We conducted these investigations and collected data from 2012 to 2020; we are now conducting an observational study to analyze this data and prepare a paper for publication.
If these results confirm the responsiveness of blood pressure to DBS, it will be possible to design and develop an artificial arterial pressure reflex device that incorporates DBS into its system, which could be applied to the treatment of Parkinson disease patients with severe orthostatic hypotension.

Methods:
We will conduct an observational study to analyze the following data collected between July 2012 and December 2020.

Analytical Methods:
(1) Description and identification of the transfer function from deep brain stimulation to blood pressure using random stimuli
(2) Design of a control center program that enables the blood pressure servo system, which compensates for blood pressure drops, to operate in the most stable and rapid manner
(3) Comparison and evaluation of the degree of blood pressure drop upon standing, with and without stimulation
(4) Comparison of the responsiveness of blood pressure to stimulation with the stimulation sites identified by MRI
(5) Examination of the degree of blood pressure drop in the seated position
(6) Comparison of blood pressure responsiveness with patients' clinical backgrounds
