Nasal Insulin to Fight Forgetfulness-Long-acting Insulin Detemir-120 Days (SL120)

Nasal Insulin to Fight Forgetfulness-Long-acting Insulin Detemir-120 Days (SL120)

Overall Status: 
No longer recruiting
Brief Description: 

The study will examine the effects of intranasally administered long-acting insulin detemir on cognition in people with Alzheimer's disease or amnestic mild cognitive impairment (aMCI).

Patient Qualifications: 
Min AgeMax AgeGenderHealthy Volunteers
50 Years

Inclusion Criteria: 

  • Age 50-89
  • Diagnosed with mild/moderate Alzheimer's disease or MCI

Exclusion Criteria: 

  • Excessively high or low blood pressure, heart rate
  • Pre-existing diabetes not controlled by exercise/diet
  • Significant elevations in lipids, liver enzymes
  • Menstrual period within the last 12 months
  • Significant neurological or medical disorder other than Alzheimer's disease
  • Prohibited medications: Previous or current use of insulin, significant use of nasal decongestants, current use of antipsychotic, anticonvulsive, anxiolytic, glucocorticoids, or sedative medications

Detailed Description: 

There is growing evidence that insulin contributes to multiple brain functions and that insulin dysregulation can contribute to Alzheimer's disease pathogenesis. Therapies aimed at restoring normal insulin signaling in the central nervous system may have beneficial effects on brain function. Intranasal administration of insulin increases insulin signaling in the brain without raising peripheral levels and causing hypoglycemia (abnormally low blood sugar).

Insulin detemir is an insulin analogue that may have better action in the brain than other insulin formulations because of its albumin-binding properties. Participants will receive insulin detemir, regular insulin, or placebo over a 4-month period. The investigators will test the hypothesis that insulin and insulin detemir will both improve memory and daily functioning in people with Alzheimer's or MCI compared with placebo, but that insulin detemir will have the greatest effect.
