### Case Study Analysis: C.Z.
#### 1. Etiology, Course, and Structural/Functional Abnormalities of Schizophrenia
**Etiology**
Schizophrenia is a complex and multifaceted mental disorder with a poorly understood etiology, though research suggests that it arises from an interplay of genetic, neurobiological, and environmental factors.
– **Genetic Factors:** Family history is a significant risk factor for schizophrenia. Studies show that individuals with a first-degree relative with schizophrenia have a 10% risk of developing the disorder, compared to the general population risk of about 1% (Kahn & Keefe, 2013). This suggests a substantial genetic component.
– **Neurobiological Factors:** Neuroimaging studies have identified several abnormalities in brain structure and function in individuals with schizophrenia. Dopaminergic dysregulation, particularly in the mesolimbic and mesocortical pathways, is a prominent feature. Alterations in glutamate, serotonin, and GABA systems also contribute (Miller et al., 2017).
– **Environmental Factors:** Prenatal exposure to infections, malnutrition, and complications during birth are associated with an increased risk of schizophrenia. Additionally, psychosocial stressors such as trauma or adverse life events can trigger the onset in predisposed individuals (McGrath et al., 2018).
**Course**
Schizophrenia typically emerges in late adolescence to early adulthood. The course of the disorder is characterized by episodes of psychosis, with periods of remission and exacerbation. The disorder is often progressive, though its trajectory can vary widely:
– **Prodromal Phase:** Early signs of schizophrenia may include social withdrawal, unusual thoughts, or mild psychotic symptoms.
– **Acute Phase:** This phase is marked by the full-blown psychotic symptoms described by C.Z., such as delusions, hallucinations, disorganized speech, and abnormal behavior.
– **Residual Phase:** After an acute episode, individuals may experience a reduction in symptoms but still exhibit residual impairments or mild symptoms.
The overall progression can be influenced by treatment adherence, social support, and comorbid conditions (Crespo-Facorro et al., 2020).
**Structural/Functional Abnormalities**
Schizophrenia is associated with several key structural and functional brain abnormalities:
– **Structural Abnormalities:** Neuroimaging studies often reveal enlarged lateral and third ventricles, reduced gray matter volume in the frontal and temporal lobes, and abnormalities in the hippocampus (Sullivan et al., 2018).
– **Functional Abnormalities:** Functional MRI and PET studies have shown decreased activity in the prefrontal cortex, which is linked to cognitive deficits and negative symptoms. Additionally, hyperactivity in the mesolimbic dopamine system is associated with positive symptoms like hallucinations and delusions (Stephan et al., 2009).
#### 2. Evidence-Based Pharmacological and Nonpharmacological Treatment
**Pharmacological Treatment**
The first-line treatment for schizophrenia involves antipsychotic medications, which are categorized into two groups:
– **First-Generation Antipsychotics (FGAs):** These include drugs like haloperidol and chlorpromazine. They primarily target dopamine D2 receptors and are effective for reducing positive symptoms. However, FGAs are associated with extrapyramidal side effects (EPS), such as tremors and rigidity (Muench & Hamer, 2010).
– **Second-Generation Antipsychotics (SGAs):** SGAs such as risperidone, olanzapine, and aripiprazole are often preferred due to their broader receptor activity, including serotonin receptor modulation, which helps address both positive and negative symptoms with a lower risk of EPS. SGAs are also associated with metabolic side effects, including weight gain and diabetes risk (Leucht et al., 2013).
For C.Z., an SGA such as aripiprazole might be an appropriate choice due to its favorable side effect profile and efficacy in treating both positive symptoms and cognitive impairments.
**Nonpharmacological Treatment**
Nonpharmacological approaches are essential for comprehensive schizophrenia management:
– **Cognitive Behavioral Therapy (CBT):** CBT can be particularly beneficial in addressing delusions and hallucinations by helping patients challenge and reframe their distorted thoughts and beliefs. It also aids in developing coping strategies and improving overall functioning (Wykes et al., 2008).
– **Psychoeducation:** Educating C.Z. and his family about schizophrenia can improve understanding of the disorder, promote adherence to treatment, and reduce stigma. This approach also provides strategies for managing symptoms and improving daily functioning (Hogarty et al., 2004).
– **Social Skills Training:** This therapy focuses on improving interpersonal skills and daily living skills, which can help C.Z. navigate social interactions and academic responsibilities more effectively (Kurtz & Mueser, 2008).
– **Assertive Community Treatment (ACT):** ACT is a team-based approach providing intensive, community-based services, including case management, vocational training, and social support, which can be beneficial for individuals with severe schizophrenia (Mueser et al., 2013).
**Conclusion**
C.Z.’s presentation aligns with symptoms of schizophrenia, characterized by delusions, hallucinations, and disorganized behavior. The etiology involves a mix of genetic, neurobiological, and environmental factors. Effective treatment combines pharmacological interventions with nonpharmacological therapies to address both symptoms and functional impairments comprehensively.

Case Study: C.Z.
| Purpose: | Analyze and apply critical thinking skills in the psychopathology of mental health
patients and provide treatment and health promotion while applying evidence-based research. |
| Scenario: | C.Z. is a 20-year-old Caucasian male who is in his second year of college. He is seeking
treatment due to persistent fears that campus security and the local police are tracking and surveilling him. He cites occasional lags in his internet speed as evidence that surveillance devices are interfering with his electronics. His intense anxiety about this has begun getting in the way of his ability to complete schoolwork, and his friends are concerned – he says they have told him, “you’re not making sense.” C.Z. occasionally laughs abruptly and inappropriately and sometimes stops speaking mid -sentence, looking off in the distance as though he sees or hears something. He expresses concern about electronics in the room (phone, computer) potentially being monitored and asks repeatedly about patient confidentiality, stating that he wants to be sure the police won’t be informed about his treatment. His beliefs are fixed, and if they are challenged, his tone becomes hostile. |
