Intranasal Insulin Reaches Brain Regions Tied to Memory

Technology Networks

description

A new imaging study from Wake Forest University School of Medicine has shown that insulin administered intranasally can reach specific brain regions associated with memory and cognition in older adults. The study, published in Alzheimer’s & Dementia: Translational Research & Clinical Interventions, also indicates that insulin uptake differs between individuals with mild cognitive impairment and those without. Using positron emission tomography (PET) and a radiolabeled insulin tracer, researchers tracked the distribution of intranasal insulin in the brains of 16 participants aged around 72 years.
