Common Diagnostic Tests for Neurogenic Orthostatic Hypotension:

  1. Tilt-table test: Measures blood pressure changes in different positions.
  2. Autonomic function tests: Assess the autonomic nervous system’s response.
  3. Blood tests: Check for underlying conditions like diabetes or vitamin deficiencies.
  4. Electrocardiogram (ECG or EKG): Monitors heart activity.
  5. 24-hour blood pressure monitoring: Tracks blood pressure throughout the day.
  6. MRI or CT scans: Identify structural issues in the brain or spine.
  7. Valsalva maneuver: Measures heart rate response to specific actions.
  8. Sweat tests: Evaluate autonomic function through sweat gland activity.
  9. Neurological exams: Assess reflexes and nerve function.
  10. Head-up tilt test: Similar to the tilt-table test, but in a different setup.
  11. Ambulatory blood pressure monitoring: Records blood pressure during daily activities.
  12. Holter monitor: Continuously monitors heart activity over 24 hours.
  13. Blood volume measurement: Determines the amount of blood in the circulatory system.
  14. Cerebrospinal fluid analysis: Checks for infections or abnormalities.
  15. Doppler ultrasound: Assesses blood flow in the arteries.
  16. Thermoregulatory sweat test: Evaluates the distribution of sweating.
  17. Carotid sinus massage: Identifies issues with blood flow in the neck.
  18. Echocardiogram: Examines the heart’s structure and function.
  19. Quantitative sudomotor axon reflex test (QSART): Measures sweat response.
  20. Postprandial hypotension test: Monitors blood pressure changes after eating.

Common Treatments for Neurogenic Orthostatic Hypotension:

  1. Increase salt intake: Boosts blood volume and helps maintain blood pressure.
  2. Fluid intake: Staying hydrated is crucial in managing symptoms.
  3. Gradual standing: Avoid sudden position changes to prevent blood pressure drops.
  4. Compression stockings: Assist in blood circulation and reduce pooling in the legs.
  5. Elevate head of the bed: Minimizes symptoms during sleep.
  6. Medication adjustments: Modify or discontinue medications causing low blood pressure.
  7. Physical counterpressure maneuvers: Techniques to counteract blood pressure drops.
  8. Midodrine: Medication that constricts blood vessels, raising blood pressure.
  9. Fludrocortisone: Enhances salt retention and increases blood volume.
  10. Pyridostigmine: Improves nerve signals, aiding blood pressure regulation.
  11. Droxidopa: Boosts norepinephrine levels, improving blood pressure control.
  12. Non-pharmacological interventions: Lifestyle changes to manage symptoms.
  13. Sleep with head elevated: Reduces symptoms during sleep.
  14. Avoid alcohol: Minimizes blood pressure fluctuations.
  15. Increase caffeine intake: May help raise blood pressure.
  16. Physical therapy: Improves muscle strength and coordination.
  17. Abdominal binders: Assist in preventing blood pooling in the abdomen.
  18. Biofeedback training: Teaches control over certain physiological functions.
  19. High-sodium diet: Supports blood pressure maintenance.
  20. Leg exercises: Promote blood circulation and prevent pooling.
  21. Stay cool: Avoid excessive heat, which can worsen symptoms.
  22. Small, frequent meals: Prevents large drops in blood pressure after eating.
  23. Avoid heavy meals: Reduces the impact on blood pressure after eating.
  24. Cognitive behavioral therapy: Helps cope with anxiety related to nOH.
  25. Supplemental oxygen: May improve blood oxygen levels.
  26. Pharmacotherapy: Medications to manage specific symptoms.
  27. Salt tablets: Boost sodium levels for increased blood volume.
  28. Water bolus: Rapid intake of water to counteract low blood pressure.
  29. Fludrocortisone: Hormone replacement to enhance salt and fluid retention.
  30. Monitor blood pressure at home: Enables timely response to changes.

  3. Spinal cord stimulation: Modulates nerve activity to manage blood pressure.
  4. Peripheral nerve surgery: Alters nerve pathways affecting blood pressure.
  5. Adrenal gland surgery: Addresses issues with hormone production.
  6. Sympathetic denervation: Interrupts nerve signals impacting blood pressure.
  7. Vagus nerve stimulation (VNS): Regulates autonomic function.
  8. Baroreceptor activation therapy: Implants a device to stimulate baroreceptors.
  9. Renal denervation: Targets nerves in the kidneys to control blood pressure.
  10. Abdominal surgery: Manages abdominal blood pooling contributing to symptoms.

In conclusion, Neurogenic Orthostatic Hypotension is a complex condition, but understanding its types, causes, symptoms, diagnostic tests, treatments, drugs, and potential surgeries is vital for effective management.
