**Question:** A 41 year old woman working as an Executive Director is convinced that the management has denied her promotion by preparing false repos about her competence and have forged her signature on sensitive documents so as to convict her. She files a complaint in the police station and requests for security. Despite all this she attends to her work and manages the household. She is suffering from:

A. **Post-Traumatic Stress Disorder (PTSD)**
B. **Obsessive-Compulsive Disorder (OCD)**
C. **Personality Disorder**
D. **Depression**

**Correct Answer:** A. Post-Traumatic Stress Disorder (PTSD)

**Core Concept:** Post-Traumatic Stress Disorder (PTSD) is a mental health condition that develops in response to a traumatic event or series of events that involves life-threatening experiences, witnessing a traumatic event, or experiencing a traumatic event as a direct victim. Symptoms include intrusive memories, avoidance behaviors, negative mood changes, and hyperarousal.

**Why the Correct Answer is Right:** The correct answer is PTSD because the described patient has experienced a traumatic event (denial of a promotion, falsified reports, and forged signatures) which triggers the development of PTSD symptoms. Her coping mechanisms include attending work and managing the household, which might be an attempt to cope with the stress. However, she seeks police assistance, indicating distress and difficulty in dealing with the situation.

**Why Each Wrong Option is Incorrect:**

A. **Obsessive-Compulsive Disorder (OCD)**: OCD is characterized by recurrent, unwanted thoughts (obsessions) and repetitive behaviors or mental acts (compulsions). The described patient does not exhibit obsessions or compulsions related to the traumatic event but instead, the coping mechanisms, distress, and seeking police help indicate PTSD.

B. **Personality Disorder**: Personality disorders involve long-standing and inflexible patterns of thinking or behavior that deviate from the diagnostic criteria for other mental disorders. The patient's behavior and distress aligns more with the PTSD diagnostic criteria, not personality disorders.

C. **Depression**: Depression typically involves persistent feelings of sadness, loss of interest, or pleasure and changes in sleep, appetite, and concentration. The patient's coping mechanisms, distress, and involvement with the police indicate that PTSD is more likely.

**Clinical Pearl:** Understanding the correct diagnosis of mental health conditions is crucial as it guides appropriate treatment strategies and helps the patient access the appropriate support systems.
