How to predict a CADASIL patient’s risk for stroke or dying

Studies are needed to best determine how to measure risk and outcomes that can be used to design clinical trials. In this study investigators from Paris, France, registered 482 CADASIL patients between 2003–2020; 60 (12%) had no follow-up and were excluded. They examined risk for having either a stroke or dying, whichever occurred first. During follow-up of 422 patients, 86 had a stroke and 58 died without a stroke. Among 99 possible predictors, they found 15 that predicted time to developing a stroke or dying. There was no single analytical method that dramatically outperformed the others. Additional studies with larger numbers of patients, longer follow-up, and novel measurements to better predict risk and define outcomes that matter to patients, will help in designing future therapeutic trials.

A comprehensive review of CADASIL and its management

The American Heart Association gathered a group of experts on CADASIL and other similar diseases. This group reviewed the available evidence and produced a comprehensive, state of the art, scientific statement. They concluded that individuals with CADASIL show variability in the nature and onset of symptoms and rates of progression, and that it is important to make a diagnosis early in its course. They make recommendations for patient management and future studies to identify new treatments.

Drug Discovery · cureCADASIL Funded

Cysteine-reactive mitigators of small vessel disease-related NOTCH3 mutants

CADASIL mutations cause abnormal folding of the NOTCH3 protein — and this study asked whether small chemical compounds could correct that misfolding. Screening 21 compounds against 16 different NOTCH3 mutations, the team identified disulfiram (Antabuse, used for alcohol dependency) and auranofin (used for rheumatoid arthritis) as the broadest-acting candidates. Because both are already FDA-approved, the path to clinical testing may be meaningfully shorter than for an entirely new drug. This research was supported in part by a grant from the University of Pennsylvania Orphan Disease Center in partnership with cureCADASIL.

Defining patient-reported outcomes and priorities for clinical trials in CADASIL through an international survey

Clinical trials need to measure what patients actually experience — not just what shows up on a brain MRI. This international survey of 226 CADASIL patients across 25 countries asked people directly what symptoms burden them most. Fatigue emerged as both the most common and most debilitating symptom, followed by cognitive fog and memory difficulties — findings that have been largely absent from natural history studies. The study also documented widespread use of unvalidated medications in the absence of evidence-based guidelines. Several cureCADASIL members are listed as co-authors, making this a landmark example of patient-partnered science.

Clinical Phenotyping · Multicenter Study

Sex-based differences in disease burden and phenotype in CADASIL: a multicenter study of 368 Korean patients

One of the largest studies of sex differences in CADASIL to date, this nationwide Korean analysis found that men develop ischemic stroke at significantly younger ages (median 53 vs. 59 years) and carry a heavier burden of brain lesions (lacunes), while women more frequently experience recurrent headaches. Importantly, the male stroke risk persisted even after controlling for hypertension and smoking — suggesting sex-intrinsic biological mechanisms (hormonal, epigenetic) are at play. These findings argue for sex-informed clinical monitoring and trial design. The study also highlights distinct patterns in Asian CADASIL populations, where variant distribution and hemorrhagic stroke rates differ substantially from European cohorts.

Epidemiology · Nationwide Cohort

Early onset, high comorbidity burden, and regional disparities of CADASIL: a nationwide cohort study in South Korea

Drawing on South Korea's national health insurance database — covering 97% of the population — this study provides one of the most comprehensive epidemiological portraits of CADASIL to date. Key findings: CADASIL patients developed every neurological condition studied (stroke, dementia, epilepsy, depression) earlier and more frequently than matched controls, and carried significantly higher overall comorbidity burdens. The island of Jeju showed an incidence more than 21 times the national average, consistent with a founder effect around the R544C NOTCH3 variant. This work underscores the need for earlier and more comprehensive clinical monitoring across the full spectrum of CADASIL manifestations — not just stroke.
