Introduction to Radiologically Isolated Syndrome

Imagine going to the doctor for something simple—maybe headaches, dizziness, or even after a minor accident—and walking out with an MRI scan that reveals something unexpected: mysterious white spots on your brain. You feel fine, you don’t have neurological symptoms, yet the images look like those seen in multiple sclerosis (MS). This scenario describes radiologically isolated syndrome (RIS), a condition that has become increasingly recognized as medical imaging grows more advanced.

RIS is unusual because it sits in a gray area of neurology. On one hand, it’s not technically a disease since the person has no symptoms. On the other hand, it can be a strong warning sign of conditions like MS, which could develop in the future. In fact, studies show that between 30% and 50% of people with RIS go on to develop MS within 10 years.

The discovery of RIS has created both challenges and opportunities in medicine. On one side, it allows doctors to detect brain changes earlier than ever before. On the other, it raises difficult questions: Should doctors treat patients who feel perfectly healthy? Should patients live as if they’re at risk for MS, or continue life as normal?

As you read further, we’ll break down everything you need to know about RIS—from what it is and how it’s diagnosed, to its relationship with MS, treatment options, and the emotional impact of living with this hidden condition.

What Is Radiologically Isolated Syndrome?

Radiologically isolated syndrome is a medical term used when MRI scans show lesions in the brain or spinal cord that look like those seen in multiple sclerosis, but the person has no symptoms at all.

To understand RIS better, let’s break it down:

• Radiologically means the findings are detected on imaging, particularly MRI.
• Isolated means these findings exist without symptoms.
• Syndrome suggests a collection of findings that don’t fit neatly into another diagnosis.

These brain lesions indicate areas where the myelin sheath—the protective covering around nerve fibers—may be damaged. This type of demyelination is the hallmark of MS. However, in RIS, the person doesn’t yet show the neurological problems usually caused by such damage.

RIS is not rare, but it’s not common either. Estimates suggest that 0.1% to 0.7% of people undergoing MRI for unrelated reasons are found to have RIS. Often, these MRIs are ordered for things like migraines, head trauma, or dizziness.

What makes RIS tricky is its uncertain future. Some people will live their entire lives with these lesions without ever experiencing MS symptoms. Others will go on to develop clinically isolated syndrome (CIS) or full-blown MS within a few years. This unpredictability is what makes RIS such an important area of research.

Another key point: RIS is not the same as MS. While the lesions look similar, MS requires clinical symptoms—like vision problems, weakness, or numbness—plus MRI evidence. RIS lacks that clinical side, which is why it falls into a separate category.

---

RIS vs. Clinically Isolated Syndrome (CIS)

At first glance, RIS and CIS might seem similar since both involve MS-like brain lesions. But the difference lies in symptoms.

• RIS: Lesions are visible on MRI, but the patient feels completely normal.
• CIS: The patient has both lesions on MRI and has experienced at least one neurological episode that suggests demyelination (for example, optic neuritis causing sudden vision loss, or numbness spreading across one side of the body).

CIS is often seen as the “first clinical step” toward MS. In fact, many CIS patients go on to develop multiple attacks, at which point they meet the criteria for MS. RIS, however, is more ambiguous—it might remain silent forever, or it might be the earliest warning sign.

Why does this distinction matter? Because treatment decisions differ greatly.

• A CIS patient might immediately be considered for disease-modifying therapies (DMTs) to slow MS progression.
• An RIS patient, on the other hand, often faces a “watch and wait” approach, with regular MRI scans and check-ups.

This creates a difficult situation for both patients and doctors. Imagine being told you have brain changes like MS but being advised not to start treatment yet. It can feel like living with a storm cloud overhead—unsure if it will ever break into rain.

---

Signs and MRI Indicators of RIS

By definition, people with RIS have no neurological symptoms. That’s what separates RIS from CIS and MS. The only “signs” come from imaging.

On MRI scans, RIS lesions typically:

• Appear as bright white spots on T2-weighted or FLAIR images.
• Are located in typical MS regions, such as:
  • Periventricular white matter (around the brain’s fluid-filled spaces)
  • The corpus callosum (connecting left and right hemispheres)
  • The spinal cord
  • The brainstem and cerebellum

These are the same areas MS tends to attack, which is why RIS raises red flags.

In some cases, RIS lesions are picked up when doctors are investigating:

• Headaches or migraines
• Dizziness or vertigo
• Trauma (like a concussion)
• Unrelated conditions (e.g., vascular scans)

The key point here is that RIS looks identical to MS on scans, which is why it sparks such concern. But without symptoms, doctors can’t diagnose MS—it remains RIS.

---

The Diagnostic Process for RIS

RIS is not diagnosed casually. Doctors must follow a careful process to make sure those brain lesions aren’t caused by something else.

The diagnostic steps usually include:

1. Detailed Medical History and Exam
   • Doctors ask about neurological symptoms (even subtle ones patients might dismiss).
   • Family history of MS or other autoimmune diseases is noted.
   • A neurological exam checks for reflexes, balance, strength, vision, and coordination.
2. Blood Tests
   • These rule out conditions that can mimic MS, such as vitamin deficiencies (B12), infections, or autoimmune disorders.
3. Cerebrospinal Fluid (CSF) Analysis
   • A lumbar puncture (spinal tap) may be performed. Doctors look for oligoclonal bands, proteins commonly found in MS. If positive, it suggests higher risk of progression.
4. Repeat MRI Scans
   • Often done at 6- to 12-month intervals. New lesions or changes in existing ones provide critical clues about disease activity.

Dr. James Lee, a radiologist, explains it this way: “RIS is a diagnosis of exclusion. You have to carefully rule out other causes before labeling it as RIS. Otherwise, you risk misdiagnosis and unnecessary anxiety.”

The bottom line: RIS is confirmed only after ruling out other explanations and confirming the lesions truly fit the MS pattern.

Causes and Risk Factors of RIS

One of the biggest challenges in understanding radiologically isolated syndrome is figuring out why it develops in the first place. Unlike conditions with clear causes, RIS sits in a medical gray area. Doctors know it involves lesions that look like MS, but they don’t always know why they form—or why some people develop symptoms while others remain unaffected for life.

Here are some of the leading factors believed to contribute:

1. Genetic Predisposition

Research has shown that multiple sclerosis has a hereditary component, and RIS appears to follow a similar trend. Individuals with a close family member who has MS are at higher risk of both RIS and eventual progression to MS.

• For example, studies suggest that siblings of people with MS have about a 2–4% lifetime risk of developing the disease compared to the general population risk of about 0.1–0.2%.
• Certain genes, especially those linked to the immune system (like HLA-DRB1*15:01), have been associated with higher susceptibility.

While genetics don’t guarantee that RIS will progress, they can stack the odds against certain individuals.

2. Environmental Triggers

Environmental factors may also play a role in RIS development. These include:

• Low Vitamin D Levels: People living farther from the equator, where sunlight is limited, tend to have higher rates of MS and RIS. Vitamin D plays a role in regulating immune function, and deficiency may increase risk.
• Viral Infections: Research has long suggested a link between Epstein-Barr Virus (EBV) and MS. Some RIS patients test positive for EBV exposure, raising the possibility that viral triggers play a role.
• Geography and Latitude: RIS and MS appear more frequently in northern latitudes, possibly due to less sun exposure and lifestyle patterns.

3. Lifestyle Influences

Certain habits and health conditions may accelerate risk of progression from RIS to MS:

• Smoking: Tobacco use is strongly associated with both increased risk of MS and faster disease progression. For RIS patients, smoking can tip the balance toward active disease.
• Obesity: Particularly in adolescence and early adulthood, obesity has been linked to increased risk of demyelinating conditions.
• Sedentary Lifestyle: Lack of physical activity can contribute to poor brain and immune health, indirectly increasing risks.

In short, RIS likely develops from a combination of genetic susceptibility and environmental exposures. While we can’t change our genes, lifestyle adjustments may influence how the condition unfolds.

Who Is Most at Risk for RIS Progression?

Not all RIS patients are created equal. Some will never develop symptoms, while others face a high likelihood of progressing to MS within a few years. Doctors use a variety of risk factors to help predict who is most vulnerable.

1. Age at Diagnosis

Younger patients, particularly those diagnosed under 35, are more likely to progress to MS compared to older adults. This may be because the immune system is more active in younger years, making demyelination more aggressive.

2. Spinal Cord Lesions

MRI findings of lesions in the spinal cord are considered a strong predictor of progression. The spinal cord controls essential functions like movement and sensation, so lesions here are more likely to eventually cause noticeable symptoms.

3. Positive Biomarkers in CSF

When cerebrospinal fluid analysis reveals oligoclonal bands or elevated immunoglobulins, the risk of progression increases significantly. These biomarkers suggest the immune system is already active in the central nervous system, even before symptoms begin.

4. High Lesion Load on MRI

The number and distribution of lesions also matter. Patients with multiple lesions in typical MS locations (periventricular, juxtacortical, infratentorial, or spinal cord) face higher risks than those with only one or two lesions.

5. Family History of MS

If RIS patients have first-degree relatives with MS, their likelihood of conversion is higher. This reflects the role of shared genetics and environmental exposures.

6. Sex and Gender

Women are more likely than men to develop both RIS and MS. In fact, MS is about three times more common in women, and RIS follows a similar pattern.

In summary: A young woman with spinal cord lesions, a family history of MS, and positive CSF markers would be considered high risk, while an older man with a single brain lesion and no biomarkers might remain stable for decades.

---

Treatment Approaches for RIS

Here is where things get complicated: there is no official standard of care for RIS. Unlike MS, which has multiple approved treatment protocols, RIS still falls into an uncertain category. Doctors must weigh the risks of overtreatment against the dangers of waiting too long.

1. Monitoring and Surveillance (Watchful Waiting)

The most common approach is regular monitoring. This means:

• MRI scans every 6 to 12 months to check for new or growing lesions.
• Neurological exams to look for early signs of MS.
• Blood and CSF testing when appropriate.

This approach works well for patients at low to moderate risk of progression. It avoids exposing patients to strong medications unnecessarily.

2. Early Intervention with Disease-Modifying Therapies (DMTs)

Some neurologists believe in early treatment, especially for high-risk RIS patients. DMTs like interferons, glatiramer acetate, or newer oral/injectable drugs have been shown to slow progression in MS.

Pros of early therapy:

• May delay or even prevent the onset of MS.
• Reduces the number of new lesions forming on MRI.
• Provides psychological reassurance to patients.

Cons of early therapy:

• These medications carry side effects like flu-like symptoms, liver damage, and immune suppression.
• High costs and insurance challenges.
• Not all RIS patients will ever progress, meaning some may take drugs unnecessarily.

3. Individualized Decision-Making

Doctors often tailor treatment decisions to each patient’s risk profile and preferences. For example:

• A 25-year-old woman with multiple spinal cord lesions might be encouraged to start treatment early.
• A 50-year-old man with a single lesion and no biomarkers might be advised to monitor instead.

Dr. David Wilson, a neuroimmunologist, puts it best: “RIS is not a one-size-fits-all condition. Some patients need aggressive early management, while others benefit from a careful watch-and-wait strategy.”

---

Lifestyle Changes to Support Brain Health

While there is no guaranteed way to prevent RIS from progressing, lifestyle choices can make a meaningful difference. Neurologists often recommend that RIS patients adopt brain-healthy habits similar to those advised for people with MS.

1. Vitamin D Optimization

Maintaining healthy vitamin D levels is crucial. Supplementation may reduce risk of disease activity, especially in patients with deficiency. Doctors often recommend daily supplements or moderate sun exposure.

2. Smoking Cessation

Smoking is one of the strongest modifiable risk factors for MS progression. RIS patients who smoke should prioritize quitting immediately to protect their neurological health.

3. Regular Exercise

Aerobic activity, strength training, and yoga not only support brain health but also improve mood and reduce fatigue. Even 30 minutes of moderate exercise 4–5 times per week can have protective effects.

4. Balanced Diet

Diets rich in omega-3 fatty acids, antioxidants, fruits, and vegetables may support brain and immune system health. Some patients adopt anti-inflammatory eating patterns like the Mediterranean diet.

5. Stress Management and Sleep

Stress hormones can influence immune system activity, potentially triggering inflammatory processes. Practices like meditation, deep breathing, and mindfulness can help. Good-quality sleep also supports immune balance.

6. Limiting Alcohol

While occasional drinking may not be harmful, heavy alcohol use can affect brain health and immunity, which may indirectly impact RIS progression.

In short, RIS patients are encouraged to think of lifestyle changes as a supportive shield—not a cure, but a way to strengthen resilience and possibly delay progression.

Home Remedies and Natural Approaches for RIS Management

While RIS is a complex neurological condition that requires professional medical guidance, patients can take proactive steps at home to support brain and nervous system health. Natural remedies and lifestyle adjustments can’t “cure” RIS, but they may help reduce inflammation, strengthen the immune system, and improve overall quality of life.

1. Vitamin D Supplementation

Low vitamin D levels are strongly linked with an increased risk of MS and its progression. Since RIS is closely related, doctors often recommend supplementation.

• Spend 15–20 minutes in sunlight daily when possible.
• Include vitamin D-rich foods such as fatty fish (salmon, mackerel), fortified milk, and eggs.
• Consider supplements if blood tests show deficiency (but only under medical supervision).

2. Omega-3 Fatty Acids

Omega-3s are known for their anti-inflammatory effects, which may protect brain and nerve cells.

• Eat fatty fish (salmon, sardines, tuna) at least twice a week.
• Add flaxseeds, chia seeds, and walnuts to your diet.
• Fish oil supplements may also be beneficial.

3. Antioxidant-Rich Foods

Oxidative stress is thought to play a role in nerve damage. Antioxidants help combat free radicals.

• Berries (blueberries, blackberries, strawberries).
• Dark leafy greens (spinach, kale).
• Nuts and seeds.
• Green tea.

4. Herbal Support

Certain herbs may support immune balance and reduce inflammation, though they should never replace medical care.

• Turmeric (Curcumin): A natural anti-inflammatory spice.
• Ginkgo Biloba: Supports blood circulation and cognitive function.
• Ashwagandha: Helps with stress reduction and immune balance.
  Always consult a doctor before using herbs, especially if you are on medications.

5. Stress Reduction Techniques

Stress has been shown to worsen autoimmune conditions, including MS. For RIS patients, keeping stress low may help prevent immune overactivity.

• Meditation: Just 10 minutes a day can calm the nervous system.
• Yoga and Tai Chi: Improve flexibility, balance, and reduce stress hormones.
• Deep Breathing Exercises: Simple breathing techniques can quickly reduce anxiety.

6. Exercise for Brain Health

Moderate exercise strengthens the immune system and improves overall health.

• Aim for 30 minutes of physical activity 5 days a week.
• Activities such as walking, cycling, or swimming are ideal.
• Avoid overexertion, which can trigger fatigue or stress.

7. Sleep Hygiene

Restful sleep is essential for the brain’s repair processes. Poor sleep can impair immunity and worsen inflammation.

• Aim for 7–9 hours per night.
• Keep a regular sleep schedule.
• Limit screen time before bed.
• Use relaxation routines like reading or herbal teas (chamomile, valerian root).

8. Gut Health and Probiotics

Emerging research links gut health to autoimmune conditions. A balanced gut microbiome may help regulate immune activity.

• Eat fermented foods such as yogurt, kefir, kimchi, sauerkraut, and miso.
• Include high-fiber foods to support healthy gut bacteria.
• Consider a daily probiotic supplement if recommended.

9. Avoid Smoking and Excessive Alcohol

Both smoking and alcohol are associated with faster progression of demyelinating diseases. Quitting smoking is one of the most powerful natural ways to reduce RIS risks.

10. Hydration and Brain Health

Staying well-hydrated helps maintain circulation and brain function.

• Aim for at least 8 glasses of water daily.
• Include hydrating foods like cucumbers, watermelon, and oranges.

When to Rely on Natural Remedies—and When Not To

It’s important to remember that natural remedies complement, but do not replace, medical care. RIS requires monitoring by a neurologist, with MRI scans and possible lab tests. Home remedies are best used as supportive strategies that strengthen your body’s resilience and overall health.

Patients should seek immediate medical attention if they develop any new neurological symptoms such as:

• Vision changes.
• Numbness or tingling in limbs.
• Weakness or balance issues.
• Cognitive difficulties.

Natural remedies can reduce risks and improve wellbeing, but professional medical care remains essential.

Diet and Lifestyle Guide for RIS Patients

Radiologically Isolated Syndrome (RIS) presents a unique challenge because patients usually have no symptoms, yet they carry MRI-detected brain or spinal lesions similar to multiple sclerosis. Since no universal medical treatment exists for RIS, lifestyle choices play a powerful role in supporting long-term brain and immune health.

This guide combines evidence-based dietary strategies, daily habits, and lifestyle adjustments to help RIS patients take control of their health.

---

✨ Key Takeaway: While RIS has no direct cure, lifestyle choices—especially diet, stress management, exercise, and sleep—play a vital role in reducing risk factors, supporting brain health, and empowering patients with control over their condition.

Emotional and Psychological Impact of RIS

Being told you have lesions in your brain or spinal cord—even without symptoms—can feel overwhelming. Many RIS patients describe the experience as living with a “diagnosis without a disease.” There’s no pain, weakness, or loss of function, but there’s also no guarantee that things will remain that way.

Anxiety and Uncertainty

One of the most common emotional reactions to RIS is anxiety about the future. Patients often find themselves asking:

• Will I develop MS?
• When will symptoms appear, if at all?
• What can I do to prevent progression?

This uncertainty can be emotionally draining. Unlike other conditions where treatment starts immediately, RIS patients often face a period of watchful waiting, which can feel like sitting on a ticking clock.

Psychological Stress of MRI Monitoring

Frequent MRI scans, sometimes every six months, can also contribute to stress. Known as “scanxiety,” this fear of bad news with each follow-up test can take a mental toll.

Social and Lifestyle Concerns

Many RIS patients struggle with how much to share with friends, family, or employers. Since they have no outward symptoms, explaining the condition can be confusing. Some patients fear being labeled as “sick” when they feel perfectly fine.

Coping Strategies

• Counseling or Therapy: Speaking with a mental health professional can help patients manage anxiety.
• Support Groups: Connecting with others in similar situations provides reassurance and reduces isolation.
• Mindfulness and Relaxation Techniques: Meditation, journaling, or yoga can reduce daily stress and improve overall resilience.
• Clear Communication with Doctors: Patients who feel informed about their condition often experience less fear of the unknown.

RIS isn’t just a medical condition—it’s a psychological journey, too. Addressing the emotional impact is just as important as monitoring physical health.

---

Prognosis and Long-Term Outlook

The big question most RIS patients have is simple: What’s going to happen to me? Unfortunately, there isn’t a single answer, since RIS has a variable prognosis.

Progression Statistics

• About 50% of RIS patients develop MS within 10 years of diagnosis.
• The other half may never develop symptoms and continue living symptom-free.
• Progression is more likely if certain risk factors are present, including spinal cord lesions, positive CSF biomarkers, or high lesion load on MRI.

Predictive Factors for Conversion to MS

Research highlights several key predictors:

• Younger age at diagnosis → higher risk.
• Female gender → slightly higher progression rates.
• Multiple brain regions affected → stronger likelihood of MS.
• Spinal cord involvement → one of the strongest predictors of progression.

Stable RIS Patients

On the other hand, some patients remain stable for decades. These are often older individuals with isolated lesions and no biomarkers of inflammation. For these patients, RIS may represent nothing more than an incidental MRI finding.

Quality of Life Considerations

Even without symptoms, RIS can affect quality of life by creating constant health-related uncertainty. However, patients who remain proactive—attending follow-up appointments, making lifestyle changes, and seeking support—often manage the condition with confidence.

The takeaway? RIS does not guarantee a diagnosis of MS, but it does warrant careful, personalized follow-up.

---

Research and Future Directions

RIS is a relatively new area of study, and research is evolving rapidly. Scientists are working hard to answer the most pressing questions: Who will develop MS, who won’t, and how can we intervene early?

Clinical Trials on Early Intervention

Several recent studies have explored whether starting disease-modifying therapies (DMTs) in RIS patients could reduce the risk of MS.

• A 2022 study in JAMA Neurology showed that early treatment reduced the number of new lesions on MRI, though the impact on long-term symptom prevention remains unclear.
• Trials are ongoing to determine which patients truly benefit from early therapy.

Biomarker Discovery

Researchers are searching for biomarkers that can better predict disease progression. Promising areas include:

• Blood tests that identify immune system activity.
• CSF analysis for specific inflammatory proteins.
• Advanced imaging techniques like PET scans to detect subtle changes in brain tissue.

Artificial Intelligence in MRI Analysis

AI is being used to analyze MRI scans more precisely, identifying patterns invisible to the human eye. This may help doctors detect RIS earlier and predict which patients are likely to progress.

Lifestyle and Preventive Medicine Studies

Beyond medications, studies are exploring the impact of vitamin D, diet, exercise, and stress reduction on RIS outcomes. If lifestyle modifications prove effective, they could become first-line interventions for many patients.

The future of RIS research is hopeful. As science advances, patients can expect more personalized and effective strategies for managing the condition.

---

Patient Stories and Experiences

Numbers and statistics only tell part of the story. To truly understand RIS, it helps to look at real-life experiences.

Emma’s Story (Age 29)

Emma discovered RIS after an MRI for chronic migraines revealed multiple brain lesions. Initially, she panicked, fearing immediate disability. With the support of her neurologist, she chose regular monitoring instead of medication. Five years later, she remains symptom-free, though she still deals with occasional anxiety around MRI scans.

Michael’s Story (Age 42)

Michael’s RIS diagnosis came after a concussion-related MRI showed spinal cord lesions. Because of his family history of MS, his doctor recommended early treatment with DMTs. After three years on therapy, Michael has not developed symptoms, and his lesion load has remained stable.

Linda’s Story (Age 55)

Linda was diagnosed with RIS after fainting at work led to an emergency MRI. Her scans showed a few lesions, but her CSF tests were negative. Given her age and risk profile, her doctors recommended only annual MRI follow-ups. Ten years later, Linda has never developed MS and lives a normal life.

These stories highlight the different paths RIS patients can take—from aggressive treatment to simple monitoring, each case requires a personalized approach.

---

Practical Tips for Living with RIS

If you’ve been diagnosed with RIS, you may feel uncertain about how to move forward. While each case is unique, these practical strategies can help patients live with confidence:

1. Stay Informed, But Avoid Over-Googling

Educate yourself about RIS, but be cautious about spending hours online reading worst-case scenarios. Stick to reputable medical sources or discussions with your doctor.

2. Keep a Health Journal

Track any unusual symptoms, energy levels, and lifestyle habits. This helps both you and your neurologist identify changes early.

3. Prioritize Brain-Healthy Habits

• Take vitamin D if recommended.
• Exercise regularly.
• Quit smoking and reduce alcohol intake.
• Follow a balanced diet rich in anti-inflammatory foods.

4. Build a Support System

Connect with family, friends, or patient support groups. Talking openly about RIS reduces feelings of isolation.

5. Manage Stress Effectively

Try yoga, mindfulness, journaling, or therapy. Stress doesn’t cause RIS, but it can worsen overall health and immune system balance.

6. Commit to Regular Checkups

Even if you feel fine, don’t skip MRI scans or follow-up appointments. Early detection of changes gives you the best chance for effective management.

Living with RIS may feel like living in limbo, but with the right approach, many patients continue to lead full, healthy lives.

---

Conclusion

Radiologically Isolated Syndrome (RIS) is a fascinating yet challenging condition. On one hand, it offers a unique window into neurological health—revealing lesions before symptoms ever appear. On the other, it leaves patients in a state of uncertainty, unsure whether these silent findings will ever progress to multiple sclerosis.

The good news is that medical science is advancing rapidly. Doctors now have a clearer understanding of risk factors, monitoring strategies, and even early treatment options. Patients, too, can play an active role by adopting healthy lifestyle habits, staying informed, and building supportive relationships with their healthcare team.

While RIS is not the same as MS, it deserves careful attention. With regular monitoring, proactive management, and ongoing research, many people with RIS can look forward to long, healthy, and fulfilling lives.

FAQs About RIS

1. Is RIS the same as early MS?

Not exactly. RIS shows MS-like lesions on MRI but without symptoms. Some patients progress to MS, but others never do.

2. How often should RIS patients get MRI scans?

Most neurologists recommend follow-ups every 6–12 months, though the schedule may vary depending on individual risk factors.

3. Can lifestyle changes prevent RIS from becoming MS?

Lifestyle changes can’t guarantee prevention, but healthy habits like quitting smoking, maintaining vitamin D levels, and exercising regularly may reduce risks.

4. Should all RIS patients start MS medications right away?

No. Early treatment is usually considered only for high-risk patients. Many people with RIS do well with careful monitoring alone.

5. Is RIS common?

RIS is relatively rare, found in only about 0.1–0.7% of people who undergo MRI scans for unrelated reasons.
