Deciphering, Construction and Validation of Magnetic Resonance Imaging Maps, Clinical Features and Outcomes in Genetic and Nongenetic Cerebral Small Vessel Diseases
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.
⁃ 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
