Reduction of Amyloid in the Brain and Retina After Treatment With IVIG for Mild Cognitive Impairment.

Objective: To assess whether intravenous immunoglobulin (IVIG) in subjects with mild cognitive impairment (MCI) results in a reduction in amyloid in the central nervous system (CNS).

Methods: Five subjects with MCI underwent baseline Florbetapir positron emission tomography and retinal autofluorescent imaging. All were administered IVIG (Octagam 10%) at 0.
