Eligibility
Inclusion criteria
Inclusion criteria: 1. Age>=45 years old, =80 points. 2. Diagnosed with cerebral small vessel disease, and the cranial MRI image within 1 year meets the 2023 international STRIVE-2 standard: a) Presumed vascular-derived cavities: subcortical round or oval cavities filled with cerebrospinal fluid, typically 3-15 mm in diameter. A Fazekas scale score of >=2 is required; b) White matter hyperintensity: hyperintensity of bilateral cerebral hemisphere symmetry on magnetic resonance T2-weighted images. A Fazekas scale score of >=2 is required; c) Cerebral microhemorrhage: magnetic resonance T2-weighted images or hypointense lesions with a diameter of 2-5mm on a magnetically sensitive sequence. Requiring >=5 microbleeding foci; d) Iron deposition on the surface of the cerebral cortex: linear hypointensity on the surface of the cerebral cortex on magnetic resonance T2 gradient echoes or other blood-sensitive sequences; 3. There is no clear history of stroke in the past, and there is no sequelae of focal neurological impairment. 4. Cognitive decline reported by the patient or observed by the clinician in the case of confirmed cerebral small vessel disease, but the cognitive impairment is not sufficient to significantly interfere with functional independence. MMSE scale > = 18 points, ADL scale > = 80 points are required. 5. Able to cooperate with the completion of neuropsychological tests, the overall cognitive function scale score decreases (below the cut-off score, or significantly decreases compared with the pre-onset level) or at least two cognitive domain scale scores in the full set of neuropsychological tests (2 standard deviations below the reference value in healthy people, or significantly decreased compared with the pre-onset level). 6. Although there may be subtle difficulties in complex functional tasks, cognitive impairment is not sufficient to significantly interfere with functional independence. MMSE scale > = 18 points, ADL scale > = 80 points are required. 7. Sign the informed consent form.
Exclusion criteria
Exclusion criteria: 1.Meet the diagnostic criteria of dementia; 2.Precuneus lesions; 3.The intracranial lesions have been diagnosed as demyelinating diseases, white matter dystrophy, intracranial space occupying lesions, autoimmune encephalitis, etc. 4.Cognitive impairment can be explained by other causes, such as Alzheimer's disease, frontotemporal dementia, dementia with lewy bodies, delirium, acute cerebral infarction, acute cerebral hemorrhage, major depression, chronic alcoholism, metabolic disorders, adverse drug reactions or brain trauma. 5.Complications such as severe anxiety, depression, excessive daytime sleepiness, mental disorders, etc., can not cooperate with cognitive function tests. 6.Combined with lower extremity fracture, joint deformity, etc., can not cooperate with gait test. 7.Combined with hearing allergy, uncontrolled hypertension, recent heart disease, severe cardiopulmonary insufficiency, malignant tumor, pregnancy, etc. 8.There are contraindications related to rTMS. a) Concomitant history of epilepsy; b) There are metal implants in the body, such as pacemakers, deep brain electrodes, vagus nerve stimulators, cochlear implants, metal stents for intracranial blood vessels, mechanical valves, etc.
