Long-Term Care and Maintenance Strategies

Once the initial Balo’s Concentric Sclerosis (BCS) attack has passed, the focus shifts to the future. A common question for patients is whether they will need to take medication for the rest of their lives. Because BCS is so rare, there is no “one-size-fits-all” established treatment guideline. Instead, your neuroimmunologist will tailor a strategy based on your specific phenotype—the way the disease is behaving in your body ^[1][2].

Safety Warning: Do not stop or alter any prescribed long-term therapies without speaking with your neurology team, as doing so can trigger a rebound attack.

The “Watch and Wait” Strategy

It may come as a relief to learn that not everyone with BCS requires long-term medication. For many, BCS is monophasic, meaning it happens once and never returns ^[3].

Observation, or “watchful waiting,” is a shared decision that is often considered when:

• The Attack was Isolated: You have only the concentric rings and no other “typical” Multiple Sclerosis (MS) spots on your MRI ^[1][4].
• Stable Monitoring: Your follow-up MRIs show that the lesions are shrinking or scarring over, with no new areas of inflammation ^[1][5].

In these cases, the risk of side effects from long-term off-label drugs may outweigh the potential benefits. You will still need regular clinical check-ups and MRI scans to ensure the disease remains “quiet” ^[3][6]. Note that recovery after the first attack does not reliably predict your relapse risk, so staying engaged with your care team is vital.

When Maintenance Therapy is Considered

In other cases, BCS behaves more like a chronic condition, such as Multiple Sclerosis. Your doctor may consider a Disease-Modifying Therapy (DMT) if:

• Recurrent Attacks: You experience a second neurological event (a “relapse”) ^[7][8].
• New MRI Activity: Your scans show new or enlarging lesions, even if you don’t feel new symptoms ^[3][9].
• MS Criteria: You have other lesions in different parts of your brain or spinal cord that meet the formal criteria for a diagnosis of Multiple Sclerosis ^[1][8]. If MS criteria are met, standard MS guidelines may inform the treatment.

Options for Long-Term Treatment

While there are no drugs approved specifically for BCS, doctors use medications that are highly effective in treating aggressive forms of MS.

B-Cell Depleting Therapies (Anti-CD20)

Currently, some specialists use anti-CD20 therapies, such as ocrelizumab and rituximab, for relapsing or MS-associated BCS ^[10][8]. These are infusions that target and remove specific B-cells in your immune system that drive inflammation.

• Effectiveness: In a small, single-center study of 10 BCS patients treated with these therapies, all 10 remained free of relapses for a median of over five years ^[10]. While encouraging, this is very low certainty evidence and cannot establish comparative safety or superiority. Rituximab and ocrelizumab are used off-label in this context.
• Major Risks: These therapies require Hepatitis B screening before starting, as they can cause viral reactivation. They also increase your risk for respiratory and systemic infections, can cause severe infusion reactions, and may lower your immunoglobulins (requiring monitoring) and alter vaccination timing.
• MRI Impact: Individual cases have shown dramatic reductions in the size of “onion-skin” lesions after starting these treatments ^[11].

Other MS Medications

Other therapies like fingolimod or natalizumab are sometimes considered, but the evidence is mixed. While some patients do well, there have been rare reports of Balo-like lesions appearing shortly after starting or stopping these specific drugs ^[7][12].

Creating Your Maintenance Plan

The goal of maintenance therapy is to prevent “dissemination in time”—meaning we want to ensure no new damage happens next month or next year ^[1]. Whether you choose observation or off-label medication, your relationship with your neurologist will involve long-term surveillance. This typically includes:

1. Scheduled MRIs: Scans to “map” any silent changes in the brain ^[3][6]. The schedule is determined by your specialist based on your specific case.
2. Symptom Tracking: Keeping a log of any new numbness, weakness, or vision changes ^[13].
3. Blood Work: If you are on a DMT, you will need regular tests to monitor your immune system health and watch for infection ^[10].
