Which condition is characterized by significant anxiety following a traumatic event?

Posttraumatic Stress Disorder (PTSD) is specifically characterized by significant anxiety and other psychological symptoms that arise following exposure to a traumatic event. Individuals with PTSD often experience recurring memories or flashbacks of the trauma, heightened arousal, and avoidance of situations that remind them of the traumatic experience. The anxiety in PTSD is deeply intertwined with the traumatic incident, often leading to emotional distress, changes in mood, and difficulties in functioning.

In contrast, Generalized Anxiety Disorder is marked by excessive worry about various aspects of life, which is not limited to a specific traumatic event. Obsessive-Compulsive Disorder involves intrusive thoughts and compulsive behaviors that are not specifically tied to trauma. Panic Disorder is characterized by recurrent panic attacks and the fear of experiencing them, but it does not focus on the aftermath of a traumatic experience as seen in PTSD. Therefore, among the choices, PTSD is uniquely associated with significant anxiety that follows a trauma, making it the correct answer.
