A 24-year-old female patient is brought to a psychiatric unit by her family. They report that she has recently begun insisting that the television is sending her secret messages and that strangers on the internet are part of a government conspiracy against her. During the interview, she speaks rapidly and jumps from one unrelated topic to another, making it difficult to follow her thoughts. Which statement best characterizes the positive symptoms she is exhibiting?

Choice A reason: Blunted affect and withdrawal are negative symptoms of schizophrenia, linked to reduced dopamine in the prefrontal cortex and ventral striatum, decreasing emotional expression and reward-seeking. The patient’s delusions and rapid speech reflect positive symptoms, driven by mesolimbic dopamine excess, making this option irrelevant to her presentation. Choice B reason: Anhedonia and avolition, negative symptoms, stem from dopamine hypoactivity in the mesocortical pathway, reducing motivation and pleasure in schizophrenia. The patient exhibits delusions and disorganized speech, positive symptoms from mesolimbic dopamine hyperactivity, not these deficits, making this choice misaligned with her active psychotic presentation. Choice C reason: Impaired memory and attention are cognitive symptoms of schizophrenia, linked to prefrontal cortex and glutamatergic dysfunction. These differ from the patient’s positive symptoms—delusions and disorganized speech—driven by dopamine excess in the auditory cortex and mesolimbic system. This option doesn’t capture her acute psychotic manifestations. Choice D reason: Delusions and disorganized speech are positive symptoms, driven by dopamine hyperactivity in the mesolimbic system and auditory cortex in schizophrenia. Delusions reflect altered reality salience, while disorganized speech indicates prefrontal cortex disruption. These match the patient’s television-related beliefs and rapid, incoherent speech, accurately characterizing her symptoms.
