An observational study in CADASIL and CADASIL (Diagnosis), sponsored by Fondazione I.R.C.C.S. Istituto Neurologico Carlo Besta. Recruiting at 2 sites in 2 countries. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-08-31.
Sponsored by Fondazione I.R.C.C.S. Istituto Neurologico Carlo Besta · Observational
The project aims to retrospectively and prospectively analyze a population of CADASIL patients in order to study the natural history of the disease by correlating the symptom spectrum with genetic risk and specific neuroradiological and biological markers
- Stratifying patients according to their disease risk, this could contribute to the discovery of personalized therapeutic targets.
33 studies on the registry are indexed under CADASIL; 18 are open to participants now.
This study's planned enrollment of 100 is below the median of 168 across 22 observational studies indexed under CADASIL.

All patients diagnosed with genetically confirmed CADASIL and followed in the Cerebrovascular Diseases Outpatient Clinic of Neurology Unit 9 from 2008 to 2023 will be enrolled in the study.

Exclusion criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Deepen the knowledge of the clinical phenotype CADASIL patient
Each patient with CADASIL will undergo to neuroimaging, correlating it with genotype (NOTCH3 gene mutation search outcome), clinical (e.g., the index event, cerebrovascular risk factors, associated manifestations) and instrumental (radiological) characterization.
Time frame: T0- T1 (24 months)
Identify potentially reversible risk factors for disease progression
At baseline, each patient will undergo collection of demographic and clinical data (e.g., the index event, cerebrovascular risk factors, associated manifestations). Disability will be assessed with the modified Rankin Scale (mRS). Neuropsychological assessment will include administration of the Montreal Cognitive Assesment (MoCA) as a screening test. Some components of executive functions will be assessed by Frontal Assesment Battery (F.A.B) scale as a screening test of executive functions, Trail Making Test (TMT) A and B to assess visual search, psychomotor speed and selective attention (TMT test A) and in addition divided and alternating attention and cognitive flexibility by TMT test B, Attentional Matrices to assess sustained attention and visual search and Modified Five Point Test to assess spatial fluency. Finally by means of the Forward Word Span and Backward Digit Span, Verbal Short-Term Memory and Working Memory will be assessed. Alongside the neuropsychological assessment of
Time frame: 0-24 months
Identify clinical, genetic, biological and neuroradiological markers
Patients will undergo an MRI study with high-field (3T) equipment consisting of standard morphologic sequences (T1 3D TSE, T2 TSE, 3D FLAIR, SWI, DWI) to assess the extent of leukoencephalopathy, its distribution pattern, the presence of gaps and/or recent ischemic lesions in DWI sequences, perivascular spaces, and concomitant microhemorrhages. Laboratory approaches aimed at differentiating progenitors of specific cell populations (e.g., endothelial and vascular smooth muscle cells) from peripheral blood mononuclear cells (PBMCs) or fibroblasts from skin will be performed. In addition, it will be possible to isolate from peripheral blood the plasma component, intended for research and characterization of potential circulating biomarkers, by appropriate multi-omics approaches (transcriptomics, proteomics, lipidomics).
Time frame: 0-30 months
Deepen knowledge of the neuroradiological phenotype of CADASIL patients, depending on the NOTCH3 mutation locus identified (high, moderate or low risk)
Patients will undergo an MRI study with high-field (3T), in particular, high-resolution volumetric FLAIR sequences will be used to allow subsequent segmentation analyses of vascular lesions and a more correct quantitative assessment of cortical thickness values of brain areas. Advanced imaging sequences, particularly epi bold resting state for the study of functional brain connectivity, will also be provided.
Time frame: 0-30 months
