55-85, Clinical Trial, Memory Impairement
The purpose of the SNIFF study is to find out whether a type of insulin, when administered as a nasal spray, improves memory in adults with a mild memory impairment or Alzheimer’s disease (AD). The study enrolled 250 adults, age 55-85 who were diagnosed with amnestic mild cognitive impairment (aMCI) or early AD. There were 26 clinical sites involved. Scientists have learned that MCI has several subtypes. In the most common subtype with high probability of progression to Alzheimer’s disease, memory loss is the most prominent feature (other types of MCI feature other types of cognitive problems).
