Traumatic Stress Syndrome
Traumatic Stress Syndrome was a psychological disorder whose symptoms included irritability, sleeplessness, obsessional thoughts, and reckless behavior.

In an alternate 2374, The Doctor diagnosed Captain Janeway with the disorder while they were passing through Krenim territory. He did this after treating Janeway for third-degree burns as a result of her deliberately entering deflector control while a fire raged inside to reactivate the main deflector array while the  was being bombarded by micrometeoroids. He classified this as reckless behavior and threatened to relieve her of duty if she did not allow The Doctor to monitor her.

Janeway refused, and was thus relieved of command. However, Janeway denied this order, even threatening to deactivate The Doctor, which he classified as yet another symptom of her instability. In the end, Janeway returned to duty knowing that she would face a court martial for refusing to follow The Doctor's orders. ()
