Research by UAB neurobiologist reveals missing chemical causing PTSD

Scientists have discovered that a chemical known as ‘neuropeptide Y’ is low or missing from the brains of those with post-traumatic stress disorder in what could be a breakthrough in treatment for PTSD, reports Patrick Thomas of ABC 33/40.

When brains function normally, neuropeptide Y is released after trauma to produce anxiety relief. Levels of neuropeptide Y are low or non-existent in those with PTSD.

This discovery could potentially lead to ways to prevent PTSD before it begins.
