Summary

This trial is testing whether intranasal insulin can help reduce symptoms of PTSD.

Who is the study for?
This trial is for men and women aged 21-65 with current PTSD who can consent to participate. It's not for those with severe brain injuries, metal in their body that affects MRI, claustrophobia, recent changes in mental health treatments, unstable medical conditions, diabetes treated with insulin or pills, high suicide/homicide risk, contraindication to insulin use or certain psychiatric disorders.
What is being tested?
The study tests if intranasal insulin can help reduce symptoms of PTSD compared to a placebo (a substance with no active drug). Participants will receive either the nasal spray containing insulin or a placebo without knowing which one they are getting.
What are the potential side effects?
Potential side effects may include local irritation inside the nose from the spray and low blood sugar levels due to insulin. Other risks might be related to typical reactions from nasal sprays such as sneezing or runny nose.
