Clinical Trial Summary

A longitudinal observational neuroimaging study of individuals with Early Onset Alzheimer's disease during the prodromal phase, and matched control group - Ultrahigh Field MRI study at 7T

Description:

This study aims to determine whether high resolution MRI at 7T and Quantitative Susceptibility Mapping (QSM) can demonstrate a specific pattern of iron overload in strategically important areas of brain as a sensitive marker of pathological Alzheimer's disease i.e. patients with subjective or mild cognitive impairment associated with Amyloid or tau pathological state in the cerebrospinal fluid.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Quantitative Susceptibility Mapping, QSM (from 7T MRI data) to hippocampal subfield volume loss at 1 year	Relationship between QSM at recruitment and to hippocampal subfield volume (QSM and hippocampal subfield volume are obtained from 7T MRI Susceptibility Weighted and T1 Weighted images)	one year
Secondary	cross-sectional and longitudinal changes in QSM in the hippocampal subfields	cross-sectional and longitudinal changes in QSM in the local hippocampal subfield QSM and volume loss after 1 year. QSM and hippocampal subfields volume will be obtained from 7T MRI data	one year
Secondary	neuropsychological measures in relation to QSM and volume loss in hippocampal subfields	neuropsychological measures at 0 and 12 months in relation to QSM and volume loss in hippocampal subfields (adjusted for APOe). QSM and hippocampal subfield volume loss are obtained from 7T MRI Susceptibility Weighted and T1 Weighted images.	one year
