Active substance
intranasal insulin
What this could lead to
If it works, this could point toward a new way to ease PTSD symptoms using a familiar drug.
What could go wrong
This is a very small early-stage trial with only 20 people, so results may not apply broadly. It is testing symptom relief, not a cure.
