The Hidden Impact of Vanishing White Matter (VWM) on Families

New Research Sheds Light on the Burden for Parents, Siblings, and Partners

A groundbreaking international study has revealed something our community has long known: Vanishing White Matter (VWM) doesn’t just affect patients. It deeply impacts their families too.

A new study, “The impact of vanishing white matter on unaffected family members,” published in the Orphanet Journal of Rare Diseases and led by Romy J. van Voorst and colleagues, represents the first large-scale effort to examine how VWM affects parents, siblings, and partners of those living with the disease.

What is Vanishing White Matter?

VWM is a rare, progressive neurological disorder caused by changes in the EIF2B1-5 genes.

It leads to the loss of white matter in the brain, disrupting communication between nerve cells.
Symptoms can progress suddenly, sometimes triggered by minor stressors such as a fever or fall.
VWM is inherited in an autosomal recessive pattern, meaning both parents must pass on the altered gene.

While research continues to search for effective treatments and cures, this study highlights another urgent need: supporting the families who live with VWM every day.

About the Study

Researchers surveyed and interviewed 100 family members across several roles:

52 mothers
29 fathers
13 siblings
6 partners

They used a mixed-methods approach, combining:

Quantitative tools: standardized health and quality-of-life questionnaires (EQ-5D-5L, EQ-5D-Y-3L, PedsQL™-FIM, PedsQL™-SC)
Custom VWM-specific inventories tailored to each family role
Qualitative interviews that captured lived experiences in their own words

This approach gave both statistical insight and deeply personal perspectives.

What Families Shared

Quantitative Results

Mothers and partners scored significantly below the general population on quality-of-life scales.
Mothers and fathers reported reduced family functioning and higher emotional strain.
Siblings were closer to norms overall, but emotional functioning—like anxiety, sadness, or loneliness—stood out as their greatest challenge.

Qualitative Themes

Three clear themes emerged across all family roles:

Lack of knowledge and empathy from healthcare providers
- Families described frustration with providers who did not understand VWM or dismissed their experiences.
The unpredictability of the disease
- Because sudden episodes can cause irreversible decline, families live with constant uncertainty.
The heavy burden of caregiving
- Emotional exhaustion, financial stress, and balancing work and family responsibilities were common across parents, siblings, and partners.

Family Perspectives

Here’s how the impact looked across different family members:

Mothers: Often reported emotional exhaustion, loss of career opportunities, and being the main point of care coordination.
Fathers: Described increased financial pressure and carrying more household responsibilities.
Partners: Shared struggles with burnout, managing daily duties, and balancing their own emotional needs.
Siblings: Talked about feeling invisible, struggling to express emotions, and living with unspoken stress.

Why This Matters

This study is a call to action. It shows that the ripple effects of VWM extend far beyond patients. To truly support our community:

Healthcare providers must offer empathetic communication and include family wellbeing in care.
Support systems should provide mental health resources, financial guidance, and peer connections for all family members.
Advocacy groups and policymakers need to recognize this “hidden burden” and fund comprehensive support services.

Moving Forward Together

Families affected by VWM already carry a heavy load. By recognizing and addressing the needs of parents, siblings, and partners, we can build a more compassionate care model that serves the whole community.

The United Leukodystrophy Foundation is committed to amplifying research like this and ensuring families feel supported, understood, and less alone.
