Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Age ≥ 60 years
* Informed, written consent form
* To fully satisfy the criteria for one of the two following 2 groups:

1. 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.
2. 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.

Exclusion Criteria

* 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.
