简要总结

The main goal of the T1rho/BBRC2017 study is to assess the capability of the MRI sequences T1rho + multicomponent T2 relaxation analysis of detecting abnormal cerebral protein deposition in AD patients in comparison with an age-matched cognitively healthy control group. Both the AD and control groups will had previously undergone amyloid PET imaging to confirm/discard cerebral proteinopathy in the context of other research studies.

入选标准

  • •Age ≥ 60 years
  • •Informed, written consent form
  • •To fully satisfy the criteria for one of the two following 2 groups:
  • •for the AD group:
  • •Diagnosed with AD as defined per the International Working Group IWG 2 criteria (fulfilling core clinical criteria plus positive core AD CSF biomarkers): Light to mild AD defined by Mini-Mental State Examination (MMSE) score between 15 and 27 (included).
  • •Documented positive visual read (as per EMA-approved procedures for each respective tracer) of an amyloid PET scan, which in the opinion of the principal investigator is consistent with a diagnosis of AD in the last 24 months.
  • •Lumbar puncture with core AD CSF biomarkers available in the last 24 months.
  • •For the cognitively health group:
  • •Normal cognition as defined by the ALFA study cognitive workup (Molinuevo et al. 2016).
  • •CONFIDENTIAL 17
  • •[18F]-Flutemetamol PET scan performed in the context of the PET FLUTEMETAMOL-FDG/BBRC2015 study in the last 24 months.
  • •Lumbar puncture with core AD CSF biomarkers preferably available in the last 24 months.

排除标准

  • •Past or present history of major brain disorders other than MCI or AD.
  • •Contraindication to MRI scanning or conditions precluding entry into the scanners (e.g. morbid obesity, claustrophobia, etc.).
  • •Participation in a clinical trial for a disease modifying drug for AD.
  • •Hypoperfusion pattern not consistent with AD diagnosis, as assessed by ASL.

结局指标
