About this trial

This is an interventional treatment trial for Cerebral Small Vessel Diseases focused on measuring Cerebral Small Vessel Diseases, Remote Ischemic Conditioning

Eligibility Criteria

45 Years - 80 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. 45-80 years old, and gender not limited;
  2. patient and/or caregiver report of cognitive declines with regard to memory and/or other cognitive domains lasting for at least 3 months;
  3. neither normal nor demented on the basis of the criteria of the Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) with normal or slightly impaired activities of daily living9, with Mini-mental State Examination (MMSE) score ≥ 20 (primary school) or ≥ 24 (junior school or above)10 and Montreal Cognitive Assessment (MoCA) score ≤ 26;
  4. the presence of lacunes and/or WMHs and/or CMBs on MRI
  5. absence of vascular narrowing >50% luminal diameter that could cause hemodynamic changes (MFV>90 cm/s for the intracranial internal carotid artery, 100 cm/s for MCA, >80 cm/s for basilar artery [BA] or vertebral artery) measured by TCD

Exclusion Criteria:

  1. clinical manifestations indicating that the patient was at the end-stage of cSVD;
  2. hereditary or inflammatory small vessel disorders
  3. cerebral venous injury or changes;
  4. diagnosis of nervous system degenerative diseases Alzheimer's disease, DLB, frontotemporal dementia (FTD), and so on;
  5. history of intracranial hemorrhage or significant bleeding in other parts of the body
  6. brain tumor, psychoses, or acute stroke within 6 months;
  7. cardiogenic embolism;
  8. significant bleeding coagulation dysfunction;
  9. serious liver and kidney function is not complete, malignant tumor, or serious diseases need to medical intervention or surgery;
  10. any soft tissue or vascular injury, and any disease of the extremities that may contraindicate RIC;
  11. pregnant women;
  12. life expectancy<6 months;
  13. refused to sign a consent form, poor compliance, or not to cooperate to complete whole treatment, and so on.

Arm Label

RIC group

Regular treatment

Arm Description

Device: Remote ischemic conditioning RIC is a non-invasive therapy that performed by an electric autocontrol device with cuff placed on arm. RIC procedures consist of five cycles of 5-min inflation (200 mmHg) and 5-min deflation of cuff on one arm. The procedure will be performed twice daily for consecutive 1 year after enrollment.

Outcomes

Primary Outcome Measures

Changes of volume of WMHs
The volume of WMHs was measured on Flairs and DTI. By calculating the mean diffusivity (MD) and FA of water diffusion, DTI can assess the integrity and connectivity of WM tissue from a network perspective, and reconstruct the distribution of WM pathways in the brain three-dimensionally.

Secondary Outcome Measures

Changes in hemodynamic parameters on TCD.
The peak systolic, mean, and end diastolic blood flow velocities (BFV) at the most proximal segment of bilateral MCAs, BA were measured by TCD
Changes of cognition evaluation on MoCA.
The Beijing version of MoCA were used to evaluate to evaluate the cognitive functions of patients, referring to the degree of an individual's capacity with respect to orientation, memory, calculation, language, execution and visuospatial function and so on
