Is it advisable to do exercise when affected by Susacs syndrome? Which activities would you suggest and how intense should they be?

For patients with Susac’s syndrome, gentle and consistent physical activity is generally recommended and beneficial, provided it is approached with caution and tailored to individual neurological and vascular stability. Because Susac’s syndrome involves microangiopathy affecting the brain, retina, and inner ear, any exercise program must be cleared by your neurologist and adapted to your current cognitive, balance, and vision-related symptoms.

Is exercise safe and beneficial for those with Susac’s syndrome?

Yes, exercise is often an essential component of recovery and long-term management for those living with Susac’s syndrome. While the condition can cause significant fatigue, cognitive "fog," and balance disturbances, inactivity can lead to muscle atrophy and worsened cardiovascular health. Physical activity helps improve blood flow, boosts mood, and assists in neuroplasticity. Among the 20 members of the DiseaseMaps.org community living with Susac’s syndrome, those who engage in low-impact movement often report better regulation of fatigue and improved mental well-being compared to those who remain sedentary.

What types of exercise are recommended for Susac’s syndrome?

The goal for someone with Susac’s syndrome is to find activities that minimize the risk of falls or overexertion. Because the disease often impacts vestibular function (inner ear), activities that provide stable support are best. Recommended activities include:

• Walking: Use a treadmill with handrails or walk on flat, even surfaces with a partner if balance is a concern.


• Stationary Cycling: Recumbent bikes offer excellent support and are safer than outdoor cycling if you experience visual disturbances or dizziness.


• Yoga and Tai Chi: These focus on controlled movements and breathing, which can help manage the stress associated with chronic illness.


• Water-based therapy: Swimming or aquatic classes provide buoyancy, reducing the load on joints while allowing for gentle resistance training.

Which activities should be approached with caution?

Due to the unpredictable nature of Susac’s syndrome, you must avoid high-impact or high-risk activities. Specifically, avoid contact sports, heavy weightlifting that requires straining (Valsalva maneuver), or activities requiring complex, rapid head movements that may trigger dizziness. If you suffer from retinal branch artery occlusions, it is vital to avoid any exercise that causes significant spikes in blood pressure. Always stop immediately if you experience increased tinnitus, blurred vision, or sudden vertigo.

How can you safely pace your activity levels?

Pacing is the most important tool for managing the daily fluctuations of Susac’s syndrome. On "good days," it is tempting to overdo it, which can trigger a "crash." Instead, use the following strategy:

1. Start low and slow: Begin with 5–10 minutes of light movement, 2–3 times per week.


2. Monitor your "energy envelope": If you feel significantly worse 24 hours after exercising, decrease the intensity or duration of your next session.


3. Medical Clearance: Ensure your neurologist and physical therapist are aware of your activity level, especially if you are currently tapering off immunosuppressive medications.


4. Listen to your brain: If cognitive fatigue increases, shorten the session immediately.

Next steps

• Consult your neurologist or a physiatrist to develop a personalized exercise plan tailored to your specific neurological deficits.


• Request a referral to a physical therapist who specializes in vestibular rehabilitation or neurological disorders.


• Connect with the 20 members of the DiseaseMaps.org Susac’s syndrome community to share experiences on pacing and activity modifications.


• Keep a daily symptom log to identify which activities may correlate with periods of increased fatigue or neurological symptoms.
