Therapeutic Effects of Intranasally-Administered Insulin in Adults with Amnestic Mild Cognitive Impairment (aMCI) or Mild Alzheimer's Disease (AD) (ADC-046-INI)

The purpose of this study is to find out if a type of insulin (Humulin® R) improves memory when it is given intranasally (as a "nasal spray") to adults with a mild cognitive (memory) impairment or early Alzheimer's disease (AD). This study will also look at the effect of intranasal insulin (INI) has on the brain structure and function and markers of AD in the cerebrospinal fluid (CSF) and blood.
