Which statement helps determine whether symptoms are due to brain dysfunction rather than purely psychological causes?

• A. Diagnoses all psychiatric disorders
• B. Assess personality traits
• C. Identify whether symptoms are due to brain dysfunction rather than purely psychological causes
• D. Measure IQ

Answer: (C)

Distinguishing whether symptoms come from brain dysfunction versus purely psychological causes hinges on identifying evidence that the brain itself is impaired. The best statement focuses directly on that question—whether the symptoms are rooted in brain dysfunction rather than being solely psychological—because it guides the clinician to pursue objective, brain-based indicators rather than relying on mood, behavior, or personality alone. In practice, this involves looking for signs of organic involvement, such as focal neurological deficits, abrupt or atypical onset (for example, after injury, infection, or metabolic disturbance), or a progressive course that suggests a brain process. Clinicians then use tools like neurological examinations, brain imaging (MRI or CT), EEG, and targeted lab tests, along with neuropsychological testing, to determine if a brain basis is present and to what extent. Other options don’t directly address whether brain dysfunction is involved: diagnosing psychiatric disorders by itself doesn’t reveal brain-based impairment; assessing personality traits doesn’t reliably indicate organic brain disease; and measuring IQ is a broad cognitive snapshot that doesn’t specify whether symptoms arise from brain pathology.
