Clinical Trial Summary

The aim is to assess the relationship between levels of IGF-I system components and cognitive status in patients with Alzheimer's disease (AD), in elderly subjects with normal cognitive function, and in patients with mild cognitive impairment (MCI).


Clinical Trial Description

AD is the most common cause of dementia. During aging, decline of biological brain functions due to a number of genetic and environmental factors facilitates the onset of AD. MCI includes prodromal AD.

The identification of the risk factors for AD must be a priority in order to define the best therapeutic approach.

Recent data support the notion that IGF-I pathway accounts for neuronal protection, with a dual effect, on both brain Aβ peptide and tau protein.

This large, multicenter, prospective, observational, cross-sectional population-based study in 3 parallel groups (200 participants per group) is aimed to assess differences between IGF-I and IGFBP3 circulating levels and polymorphisms in AD patients and control elderly subjects, and in MCI patients. ;
