For individuals living with multiple sclerosis (MS), managing blood pressure is not just about cardiovascular health—it is a critical component of neurological preservation. Research indicates that hypertension is approximately 25 percent more common in people with MS than in the general population, creating a compounding effect on the body and brain.
The Connection Between Blood Pressure and MS Progression
High blood pressure (hypertension) occurs when the force of blood against artery walls is consistently too high. This often results from narrowed or less flexible arteries due to plaque buildup (atherosclerosis).
While hypertension is a risk factor for everyone, it presents unique challenges for those with MS:
- Accelerated Brain Atrophy: High blood pressure can lead to faster brain shrinkage (atrophy) and increased neurological damage.
- Compounded Symptoms: The damage caused by hypertension can exacerbate MS symptoms, leading to increased fatigue, cognitive “fog,” memory issues, and diminished walking ability.
- The “Silent” Risk: Hypertension is often asymptomatic, meaning damage can occur for years without warning. In extreme cases, it can trigger a stroke, which may cause sudden loss of balance or coordination—symptoms that can be difficult to distinguish from an MS relapse.
Understanding Your Numbers
Blood pressure is measured using two figures: systolic (the pressure during a heartbeat) and diastolic (the pressure between beats).
| Category | Systolic (Top Number) | Diastolic (Bottom Number) |
|---|---|---|
| Normal | Less than 120 | AND less than 80 |
| Elevated | 120 – 129 | AND less than 80 |
| Hypertension | 130 or higher | OR 80 or higher |
Strategies for Management
The fundamental approach to managing blood pressure remains the same for MS patients as it does for the general public, but the implementation must be personalized.
1. Lifestyle Interventions
Doctors often recommend several key changes to lower blood pressure naturally:
* The DASH Diet: This dietary approach is specifically noted for its ability to lower blood pressure and potentially reduce neurodegeneration (brain damage).
* Sodium Reduction: Cutting back on salt is a primary goal.
* Physical Activity & Weight Management: Maintaining a healthy weight and staying active.
* Habit Changes: Limiting alcohol and quitting tobacco.
2. Medication and Personalization
If lifestyle changes are insufficient, physicians may prescribe medication to relax blood vessels or reduce fluid retention. However, for those with MS, medication choice is sensitive. Some drugs can cause side effects like dizziness, fatigue, or frequent urination—symptoms that may overlap with or worsen existing MS complications.
“Which lifestyle measures are most effective, and which medications are best, are things that a physician would want to tailor to a person’s cardiovascular health and lifestyle,” says Dr. Christopher Orlando, a neurologist at Keck Medicine of USC.
Navigating Overlapping Symptoms
One of the greatest challenges for MS patients is distinguishing between a progression of MS and the side effects of blood pressure medication or the symptoms of hypertension itself. Both conditions can cause:
* Fatigue
* Headaches
* Cognitive difficulties
* Bladder issues
Because of this overlap, it is vital to monitor symptoms closely and report any new changes—such as increased dizziness or muscle cramps—to your medical team immediately.
Building Your Healthcare Team
Managing MS and hypertension simultaneously requires a coordinated effort. While a neurologist manages MS, a primary care physician or a cardiologist is often essential for managing blood pressure.
Key questions to ask your doctor:
– What is my specific target blood pressure?
– Could my MS treatments (such as steroids) be raising my blood pressure?
– Are there medications that avoid side effects like dizziness or fatigue?
– How often should we re-evaluate my treatment plan?
Conclusion
Controlling high blood pressure is a vital tool in slowing MS progression and protecting brain integrity. By combining dietary changes, regular monitoring, and a coordinated medical team, individuals can better manage the intersection of cardiovascular and neurological health.
