Multiple Sclerosis (MS) can go into long term remission, particularly in individuals with the relapsing remitting form of the condition. Remission is a period where no new inflammatory activity occurs in the central nervous system, and existing symptoms either remain stable or improve. While remission does not mean the disease has been cured, modern disease modifying therapies (DMTs) have made it increasingly possible for patients to achieve a state often called NEDA (No Evidence of Disease Activity), where they experience no new relapses or brain lesions for several years.
Multiple Sclerosis is a chronic autoimmune condition where the immune system attacks the myelin sheath surrounding nerve fibres. A remission occurs when this inflammatory attack subsides, allowing the body a chance to potentially repair some of the damage through a process called remyelination. However, even during long term remission, the underlying condition remains present, and ongoing management is essential to prevent future flares. This article explores the biological mechanisms of remission, the role of modern medicine in extending these stable periods, and how to maintain health during a remission.

Understanding Remission and Stable Periods
In the context of Multiple Sclerosis, remission refers to a phase where the immune system is not actively attacking the central nervous system. For those with Relapsing Remitting MS, these periods follow a relapse and can last for months or even years. During this time, the inflammation in the brain and spinal cord decreases, and some of the symptoms experienced during the relapse may fade as the nerves recover.
It is important to understand that remission is not a permanent absence of the disease. Instead, it is a period of clinical stability. Some people may still experience baseline symptoms, remnants of past damage, but they do not experience new worsening. Modern neurology aims to make these remissions as long and robust as possible. When a patient reaches a point where MRI scans show no new lesions, and there are no physical relapses, clinicians refer to this as a stable disease state.
The Role of Disease Modifying Therapies
The primary way long term remission is achieved today is through the use of disease modifying therapies. These medications work by regulating or suppressing the immune system to prevent it from attacking the myelin in the first place. By reducing the number of hits the nervous system takes, these therapies allow for much longer periods of health and stability.
Current clinical strategies focus on Early Intensive Treatment. Research indicates that starting highly effective therapies shortly after diagnosis can significantly increase the chances of achieving long term remission and preventing the transition to progressive forms of MS. These treatments are designed to:
- Reduce the frequency of relapses.
- Prevent the formation of new lesions on MRI scans.
- Slow down the accumulation of physical disability.
- Maintain cognitive function over time.
For many patients, being on the right therapy can lead to years of high quality life with minimal interference from MS symptoms.
Causes and Physiological Mechanisms of Repair
When the immune system stops its attack during remission, the body may attempt to fix the damaged myelin. This natural repair process is called remyelination. While the body’s ability to repair myelin is not perfect, it can be enough to restore some nerve signal conduction and improve physical function.
| Process | Description | Result during Remission |
| Inflammation Subsides | Immune cells leave the central nervous system. | Reduced swelling and pressure on nerves. |
| Remyelination | Specialist cells create new myelin layers. | Restored or improved nerve signal speed. |
| Neuroplasticity | The brain forms new pathways to bypass damage. | Improvement in coordination or speech. |
| Metabolic Recovery | Nerve cells regain better energy efficiency. | Reduction in the severity of MS fatigue. |
Factors That Influence the Length of Remission
While medication is the most significant factor in maintaining remission, lifestyle and environmental factors also play a supporting role. Because MS is a complex condition, keeping the body in a healthy state helps the immune system remain regulated. Consistency in taking prescribed medications is the most critical factor for success.
Factors that support long term remission include:
- Vitamin D Levels: Maintaining adequate Vitamin D is linked to lower relapse rates.
- Smoking Cessation: Stopping smoking is one of the most effective ways to slow disease progression.
- Stress Management: High stress can sometimes act as a trigger for immune system overactivity.
- Infection Prevention: Staying up to date with vaccinations prevents infections that can cause pseudo relapses.
Skipping doses or stopping treatment without medical supervision significantly increases the risk of a remission ending abruptly. Regular follow ups with a clinical team ensure that any subtle changes are caught early.
Differentiation: Remission vs. Progressive Stability
It is helpful to distinguish between a true remission in Relapsing Remitting MS and the stable periods sometimes seen in progressive forms of the disease.
| Feature | RRMS Remission | Progressive Stability |
| Pattern | Follows a clear attack or flare up. | A plateau in a steady decline. |
| Recovery | Symptoms often significantly improve. | Symptoms remain the same; rarely improve. |
| MRI Activity | Usually shows no new active inflammation. | May show slow, smouldering changes. |
| Treatment Goal | To prevent any new relapses. | To slow the rate of gradual worsening. |
To Summarise
Multiple Sclerosis can go into long term remission, and for many people, these stable periods can last for years. This is largely made possible by modern disease-modifying therapies that prevent the immune system from attacking the central nervous system. During remission, the body has a chance to repair damage, and symptoms may improve. Maintaining a healthy lifestyle and adhering to a treatment plan are essential for extending these periods of health and preventing future relapses.
If you experience severe, sudden, or worsening symptoms, such as a sudden loss of vision, severe weakness in your limbs, or a significant new difficulty in breathing or swallowing, call 999 immediately.
Is long term remission the same as being cured?
No, a remission means the disease is currently inactive or stable, but the underlying condition remains and requires ongoing monitoring and management.
Can I stop my medication if I have been in remission for years?
You should never stop MS medication without consulting your neurologist. Stopping treatment often leads to a return of disease activity, even after a long stable period.
How do I know if I am in remission?
Remission is usually confirmed by a lack of new physical symptoms and MRI scans that show no new or active lesions in the brain or spinal cord.
Does everyone with MS experience remission?
Remission is most common in the relapsing remitting form of MS. Those with progressive forms may experience stable periods, but these are generally not called remissions.
Can stress end a remission?
While stress is not the primary cause of MS, significant emotional or physical stress can sometimes trigger a relapse or a temporary worsening of symptoms.
Does diet help maintain remission?
While no diet is a cure, a healthy, balanced diet supports overall immune health and can help manage symptoms like fatigue during remission.
Is it possible to have a 10 year remission?
Yes, with modern treatments, some individuals experience a decade or more without a new relapse, though regular clinical check ups remain vital.
