Study of Intravenous Immunoglobulin in Amnestic Mild Cognitive Impairment

Summary

Patients with mild cognitive impairment (MCI) are a group recognized at being at high risk of progressing to Alzheimer disease. Treatment of MCI with immunotherapy with intravenous immunoglobulins (IVIG) could potentially reduce the risk of progression to Alzheimer disease. This study will evaluate the efficacy of intravenous immunoglobulin in patients with MCI over 24 months after the first infusion. This study will also document conversion from MCI to Alzheimer's Disease.
