Living with CADASIL
Living with CADASIL means managing what you can — blood pressure, activity, mental health — while getting support for what you can't. The disease course varies widely; many people stay stable for years. Depression, apathy, and fatigue are common and treatable, and caregiver support matters as much as patient care.
This is the part the clinic rarely covers. Prognosis varies enormously — plenty of people stay mild and stable for a long time, and baseline health is the biggest predictor. Treat the depression and fatigue; they're part of the disease, not weakness. Build a care team that actually knows CADASIL. And don't carry it alone — caregivers need support too, because watching this is its own kind of hard.
Prognosis, honestly: Avoid the single scary “life expectancy” number. Peer-reviewed data show median age at death roughly ~65 (men) and ~71 (women), with wide variation: people with little damage at baseline had >80% survival over 18 years and stayed mild for nearly two decades. Baseline lesion/disability burden is the strongest predictor.
Common questions
- What is the life expectancy with CADASIL?
- It varies widely; peer-reviewed medians are ~65 (men)/~71 (women), but many people remain stable for years. Baseline health matters most.
- Does everyone with CADASIL end up with dementia?
- No — severity varies greatly; some remain mild for a long time.
- Where do I find a CADASIL-literate doctor?
- Seek neurologists or academic centers experienced in small-vessel disease; advocacy groups like cureCADASIL can help.
