Explanation

The lifetime prevalence of schizophrenia is considered to be equal between men and women.
While the overall rate is the same, the clinical presentation and course of the illness show significant gender differences.
For example, males tend to have an earlier age of onset and are often more affected by negative symptoms, leading to a generally poorer prognosis than females.

Option A: The stated ratio of 1 in 1000 (0.1%) is a significant underestimation. Authoritative sources place the lifetime prevalence at 0.3-0.7%, which is 3 to 7 people per 1000.
Option B: This age range (25-35 years) is the peak onset period specifically for females. It does not accurately represent the overall peak onset, as males typically have an earlier onset (10-25 years).
Option D: The prognosis for any type of schizophrenia is variable and rarely described as simply 'good'. While catatonic schizophrenia can respond well to specific treatments like ECT, the overall long-term outcome is complex and often involves chronic impairment.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Epidemiology and characteristics of Schizophrenia as background academic context rather than a clinical decision trigger.
Understanding the epidemiology of schizophrenia helps nurses in early identification, especially when assessing young adults presenting with behavioral changes.
Knowledge of gender differences is crucial for patient education. For instance, a nurse can explain to the family of a young male patient why the onset is earlier and what to expect regarding negative symptoms.
Recognizing that prevalence is equal across genders helps combat stereotypes and ensures that screening and support are offered without gender bias.

How to Approach the Question

This is a factual recall question that asks you to identify the true statement among several options about schizophrenia.
First, read the question stem carefully to understand what is being asked: 'What is true about schizophrenia?'.
Evaluate each option independently based on your knowledge of the disorder's epidemiology and clinical features.
Option A (prevalence): Recall the approximate prevalence. Is 1 in 1000 correct? It's closer to 1 in 100.
Option B (age of onset): Think about the typical age of onset. Does 25-35 apply to everyone? Recall that it differs by gender.
Option C (gender): Consider the overall prevalence in males versus females. Is it equal?
