Leonard, who is bullied at school and shows increased agitation, may be diagnosed with what condition?

Leonard's situation aligns with the characteristics of post-traumatic stress disorder (PTSD), which can develop after experiencing or witnessing a traumatic event, including ongoing bullying. Symptoms of PTSD can include heightened levels of anxiety, agitation, flashbacks, and avoidance of reminders of the trauma, all of which could be present in a person who is being bullied.

While generalized anxiety disorder focuses on excessive worry and anxiety across various situations without a specific triggering event, PTSD is more specifically linked to trauma exposure. Similarly, bipolar disorder involves mood swings that range from manic highs to depressive lows, and obsessive-compulsive disorder entails unwanted, intrusive thoughts and behaviors aimed at reducing anxiety. None of these conditions directly address the experience of trauma related to bullying in the same way PTSD does. Thus, Leonard's heightened agitation in response to bullying is most appropriately classified under PTSD.
