About this study

Official title: Neurocognitive and Radiological Assessments in Adult Patients With Moyamoya Disease Undergoing Surgical Revascularization

Adult patients with moyamoya disease (MMD) are reported to suffer from considerable impairment of executive function/attention. Although reduced cerebrovascular reserve (CVR) in frontal areas has been detected by perfusion MRI and then confirmed to be associated with executive dysfunction in adult MMD, the structural and functional changes is still unclear with progression of executive dysfunction. Furthermore, it is very important to study the association between the neurocognitive and radiological improvement after surgical revascularization, so as to help detecting cerebral regions which are involved in executive deterioration or improvement after surgery. Then the investigators can determine whether these regions can be used as indicators to decide rational therapeutic schedule and timing of adult MMD with executive dysfunction.

Thus the aim of this study is to primarily find out the neuropsychological and radiological correlates in adult MMD, and then to quantitatively evaluate the effectiveness of surgical revascularization in prevention of executive dysfunction in adult MMD.

Read the detailed description

Previous studies of adult moyamoya disease (MMD) have revealed that vascular cognitive impairment (VCI) is the consequence of ischemic damage to dynamic factors such as cerebral hypoperfusion, rather than to cerebral gray matter. However, it is still unclear which regions are affected by MMD and how these regions respond to the progressive cognitive decline. In other way, the investigators need to detect spatial patterns in the brain activity of MMD in order to understand its pathophysiological nature.

Surgical revascularization has been accepted as the only effective form of treatment in preventing future ischemic episodes. However, its effectiveness in cognitive protection is still unknown. Thus, the investigators determine to quantitatively evaluate cognitive and radiological outcomes in adult MMD postoperatively and during follow-ups.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Surgical RevascularizationProcedure or surgery

    Most patients in this group will be performed combined procedures of superficial temporal to middle cerebral artery bypass (STA-MCA) and encephalo-duro-myo-synangiosis (EDMS). Patients not suitable for combined procedures will be performed EDMS.

  • Conservative treatmentOther

    Patients will be medically treated with antiplatelets, antiepileptics, antihypertensives and vasodilators depending on the presentation.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Neurocognitive outcomes at 3/6/12/24-month follow-up after surgical revascularization or conservative treatment.

    Measure neurocognitive outcomes with a battery of neuropsychological tests covering global cognition, executive, memory, language, and visuospatial functions. It involves the Mini-mental state examination (MMSE), the Memory and Executive Screening test (MES), the Trail Making Test (TMT), the Auditory Verbal Learning Test (AVLT), the verbal fluency test (VFT), the Rey-Osterrieth complex figure test (CFT), etc.

    Measured: 2 years

Secondary outcomes (7)
  1. The number of participants who suffer from all stroke or death during 30 days to 24 months

    Measured: 24 months

  2. The number of participants who suffer from all kinds of adverse events related to surgery.

    Measured: 30 days

  3. Postoperative neurocognitive outcomes before discharge.

    Measure neurocognitive outcomes about 1 week after surgery according to participants' physical condition, using the tests mentioned in the primary outcome measurement.

    Measured: average of 1 week after surgery

  4. Postoperative radiological outcomes before discharge.

    Measure cerebral perfusion simultaneously with neurocognitive testing, using the single photon emission computed tomography (SPECT).

    Measured: average of 1 week after surgery

  5. The changes from baseline in modified Rankin scale (mRS) and national institutes of health stroke scale (NIHSS).

    Measured: at 7 days, 30 days, 3/6/12/24 months

  6. The changes from baseline in single photon emission computed tomography (SPECT).

    Measured: 2 years

  7. The changes from baseline in blood oxygen level-dependent functional magnetic resonance imaging (BOLD fMRI) during rest.

    Data analysis techniques include amplitude of frequency fluctuation (ALFF), regional homogeneity (ReHo), independent component analysis (ICA), voxel-based morphometry analysis (VBM), etc.

    Measured: 2 years
