NCT01856699

Brief Summary

Aim of the SuSPect-CAA study is to prospectively evaluate the prognostic significance of cortical superficial siderosis in patients with suspected cerebral amyloid angiopathy with a primary focus on future stroke and mortality.

Study Arms (2)

Study Group

You may qualify if:

  • Fulfillment of the modified Boston criteria for CAA-related hemorrhage with evidence of supratentorial superficial siderosis on MRI
  • MR-/CT-/digital subtraction (DS) -angiography without evidence of cerebral aneurysm, arterio-venous malformation (AVM) , AV-fistula or other pathology of relevance (e.g. tumor, hemorrhagic infarction)
  • A maximum of two lobar or cerebellar intracranial hemorrhages (ICH) (old or acute)
  • Written informed consent by patient or guardian prior to study participation
  • Willingness to participate in follow-up
  • Fulfillment of the classic Boston criteria for CAA-related hemorrhage
  • Absence of superficial siderosis on MRI
  • A maximum of two lobar or cerebellar ICHs (old or acute)
  • MR-/CT-/DS -angiography without evidence of cerebral aneurysm, AVM, AV-fistula or other pathology of relevance (e.g. tumor, hemorrhagic infarction)
  • Written informed consent by patient or guardian prior to study participation
  • Willingness to participate in follow-up

You may not qualify if:

  • Severe medical condition with expected life expectancy \<3 years
  • More than two lobar or cerebellar ICH (old or acute)
  • any intracerebral hemorrhage in the deep grey matter (basal ganglia or thalami) or in the brain stem
  • Cerebral aneurysm or history of aneurysmal subarachnoid hemorrhage
  • Infratentorial siderosis
  • Infratentorial subarachnoid hemorrhage
