Comparing brain imaging techniques in patients with mild cognitive impairment and subjective cognitive decline

Clinical Applicability of Pseudo-continuous Arterial Spin Labeling as a Substitute for FDG-position Emission Tomography in MCI and SCD Patients

Observational University of Milano Bicocca · NCT05756270

This study is testing if a new brain imaging technique can be a good alternative to a standard method for checking blood flow in the brains of people with mild cognitive issues and memory concerns.

What this trial studies

This observational study aims to evaluate the effectiveness of pseudo-continuous arterial spin labeling (pCASL) as a potential substitute for fluorodeoxyglucose positron emission tomography (FDG-PET) in assessing cerebral perfusion in patients with mild cognitive impairment (MCI) and subjective cognitive decline (SCD). Participants will undergo brain imaging using both pCASL and FDG-PET, along with lumbar punctures and blood tests to analyze biomarkers related to cognitive decline. The study will also investigate the correlation between hypoperfusion patterns identified by pCASL and metabolic patterns observed with FDG-PET, as well as the ability of pCASL to predict conversion to dementia over a three-year period.

Who should consider this trial

Good fit: Ideal candidates include individuals diagnosed with mild cognitive impairment or subjective cognitive decline who meet specific clinical criteria.

Not a fit: Patients with contraindications to MRI or FDG-PET, secondary causes of cognitive decline, or significant neurological or psychiatric comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a less invasive and more accessible method for assessing brain function in patients at risk of dementia.

How similar studies have performed: While there have been studies exploring the use of pCASL in cognitive decline, this specific comparison with FDG-PET in MCI and SCD patients is relatively novel.
