Deep brain stimulation: a new treatment for hypertension?

Area of Science:

• Neuromodulation
• Pain Management
• Cardiovascular Physiology

Background:

• Chronic neuropathic pain, particularly in the oral cavity, significantly impacts quality of life.
• Hypertension is a prevalent condition requiring effective management strategies.
• Deep brain stimulation (DBS) is an established therapy for certain neurological disorders.

Observation:

• A 61-year-old male patient with hypertension and chronic oral neuropathic pain received DBS.
• The target area for stimulation was the periventricular/periaqueductal gray matter.
• Intraoperative stimulation demonstrated the ability to influence blood pressure levels.

Findings:

• Electrical stimulation within the midbrain periventricular/periaqueductal gray area modulated the patient's blood pressure.
• Blood pressure could be increased or decreased based on precise electrode placement.
• This represents the first reported instance of hypertension management via midbrain electrical stimulation.

Implications:

• Midbrain DBS may offer a novel therapeutic avenue for managing hypertension.
• Further research is warranted to explore the efficacy and safety of this neuromodulation technique for cardiovascular control.
• This study opens new possibilities for utilizing brain stimulation in treating systemic conditions beyond pain.
