A 28 year old female presents with complains of reduced sleep with disorganized behaviour since 9 months. She feels there is a camera fixed behind her head which always follows her. Which of the following is likely diagnosis?
**Core Concept**
The underlying principle being tested is the diagnosis of psychiatric disorders, specifically **schizophrenia**, which is characterized by a disintegration of the process of thinking, of contact with reality, and a disintegration of personality. The patient's symptoms, such as disorganized behavior and delusions, are key features of this condition. **Psychotic disorders** are a group of severe mental illnesses that cause abnormal thinking and perceptions.
**Why the Correct Answer is Right**
The patient's complaint of a camera fixed behind her head, which always follows her, is a classic example of a **delusion of persecution**, a type of delusion commonly seen in schizophrenia. The patient's disorganized behavior and reduced sleep also support this diagnosis. Schizophrenia is a chronic and severe mental disorder that affects how a person thinks, feels, and behaves, and is characterized by a range of symptoms, including **hallucinations**, **delusions**, and **disorganized thinking**.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the symptoms described do not match those of a mood disorder, such as depression or bipolar disorder.
**Option B:** This option is incorrect because anxiety disorders do not typically present with delusions or disorganized behavior.
**Option C:** This option is incorrect because personality disorders do not typically present with psychotic symptoms such as delusions.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that schizophrenia is characterized by a combination of positive symptoms, such as **hallucinations** and **delusions**, and negative symptoms, such as **social withdrawal** and **apathy**. Early recognition and treatment of schizophrenia can significantly improve outcomes.
**Correct Answer:** D. Schizophrenia.
