Why does MS increase risk of stroke?

Question

Hi doctor,

I’ve been diagnosed with multiple sclerosis, and I recently suffered a stroke. I’m trying to understand how these two conditions might be connected better.

Is it possible that having MS could increase my risk of a stroke or affect how severe it is?

Since the stroke, I’ve had more trouble with mobility, weakness on one side of my body, and some cognitive issues like memory problems and trouble concentrating. I’m wondering:

Are these symptoms more likely from the stroke, or could they be signs of an MS flare-up?
Also, are there specific tests or imaging methods that can help monitor both MS and stroke-related changes?
I’m concerned about the possibility of having another stroke. Does MS make that more likely? What steps can I take to help reduce that risk?
Lastly, are there any rehab programs or therapies that address both neurological and vascular recovery? I’m hoping to regain as much function and independence as possible.

Please help.

Thank you.

Hi,

Welcome to icliniq.com.

I’ve reviewed your concerns and truly understand how challenging it must be to navigate both multiple sclerosis (MS) and a recent stroke.

While MS and stroke are different conditions, they can sometimes present with similar neurological symptoms, since both involve damage to the brain.

MS flare-ups vs. stroke symptoms:

MS flare-ups often develop gradually over hours to days. Vision changes with MS are typically partial, such as blurred or cloudy vision, rather than complete loss. In some cases, symptoms may appear suddenly and last for seconds or minutes. These are known as paroxysmal symptoms.
Stroke symptoms usually have a sudden onset and may include numbness, confusion, slurred speech, visual disturbances (often total vision loss in one eye), difficulty walking, or balance issues. These symptoms are typically more abrupt and intense than MS flares.

If you notice any sudden or severe symptoms, it's critical to seek emergency medical care immediately. Time-sensitive treatments, like clot-busting medications, can make a significant difference if administered within the first 4.5 to 6 hours of stroke onset.

Diagnosis and monitoring: MRI is the gold standard for evaluating both MS lesions and stroke-related damage. The imaging patterns are different, which helps neurologists distinguish between the two conditions.

Reducing stroke risk and supporting MS management:

Here are some evidence-based strategies to help reduce stroke risk and support overall neurological health:

Quit smoking if you do; this significantly lowers stroke and MS progression risks.
Manage stress with mindfulness, breathing exercises, or therapy.
Stay active with low-impact exercises like walking, swimming, cycling, or adaptive activities like therapeutic horseback riding.
Medications for MS: High-dose IV corticosteroids can help reduce the duration and severity of MS flare-ups. In more severe cases, plasma exchange may be considered.
Nutrition: Focus on a balanced diet rich in vegetables, fruits, lean proteins (such as liver, shellfish, and tofu), and healthy fats. Limit processed foods, sugary drinks, fried items, and heavily preserved meals.
Supplements: Many MS patients benefit from vitamin D3, B12, folate (B9), omega-3 fatty acids, and probiotics. Consult your physician before starting any supplements.
Rehabilitation: Multidisciplinary rehab is key. Physical therapy, occupational therapy, neurorehabilitation, and cognitive therapy can all help improve mobility, strength, and mental clarity.
Support from family, friends, and mental health professionals can also play a vital role in your recovery and overall well-being.
