Official title
Deciphering, Construction and Validation of Magnetic Resonance Imaging Maps, Clinical Features and Outcomes in Genetic and Nongenetic Cerebral Small Vessel Diseases
Overview
The TAG-SVD enrolled patients with clinical and neuroimaging features of cerebral small vessel disease (CSVD). All enrolled patients will receive next-generation sequence (NGS) with probes designed to target five candidate CSVD genes, and patients will be divided into genetic or non-genetic groups accordingly. Their clinical features and outcome will be followed for at least 2 years.
Interventions
- Diagnostic test MRI
Patients will repeat study-protocol MRI at baseline (enrollment) and at least once in 1 year or 2 years follow-up (depends on availability).
Primary outcome measures
- Number of patients with incident stroke [Time frame: 2 years]
Secondary outcome measures (1)
- Number of patients with incident dementia [Time frame: 2 years]
Eligibility criteria
Inclusion criteria
Participants must have at least one of the following symptoms/signs or history
- stroke (especially small vessel occlusion type of ischaemic stroke, spontaneous ICH or young stroke)
- cognitive impairment or dementia
- gait disturbance
- parkinsonism (especially vascular parkinsonism features)
- headache (especially migraine)
- positive family history of hereditary CSVD
- MRI evidence of CSVD (MRI may be done for other reasons), including mild to moderate white matter hyper intensity, any lacune, or any cerebral microbleed
Exclusion criteria
- MRI evidence of CSVD due to other inflammatory, malignancy, or structural lesions
- patients or family members not willing to sign informed consent
Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
