Major Chandra, an infantry soldier, was posted in the border area with his unit. One day, an informer gave a message that terrorists have entered in a school and are threating to blow it, if some of their terrorist prisoners are not released. The major entered the school premises along with other soldiers, but was shocked to see the terrorists armed with the latest weapons. Soon the firing started, as the terrorists had an advantageous position so they immediately shot down a few soldiers without caring for their life. Major Chandra entered the school and started firing which led to killing of the terrorists and he got badly injured. Though the Major has recovered, still he gets flashback and recurring nightmares.

Identify the disorder, Major Chandra is suffering from:

Post-traumatic Stress Disorder

The correct answer is Option (2) → Post-traumatic Stress Disorder

Major Chandra's symptoms, such as flashbacks and recurring nightmares, are hallmark signs of PTSD. This disorder develops in response to experiencing or witnessing a traumatic event, such as the life-threatening situation Major Chandra faced during the terrorist encounter.

"Trauma- and Stressor-Related Disorders : Very often people who have been caught in a natural disaster (such as tsunami) or have been victims of bomb blasts by terrorists, or been in a serious accident or in a war-related situation, experience post-traumatic stress disorder (PTSD). PTSD symptoms vary widely but may include recurrent dreams, flashbacks, impaired concentration, and emotional numbing. Adjustment Disorders and Acute Stress Disorder are also included under this category."
