Final answer:
Cognitive symptoms of schizophrenia tend to persist even with treatment. These symptoms are a recognized aspect of the illness but not a primary diagnostic criterion. They can be present before the onset of psychosis and may also be seen in non-psychotic relatives.
Step-by-step explanation:
Of the statements regarding cognitive symptoms of schizophrenia made by Dr. Brubaker, the most accurate one is that cognitive symptoms tend to persist even with treatment. Symptomatic relief for schizophrenia primarily targets hallucinations, delusions, and negative symptoms, but cognitive deficits, such as problems with memory, attention, and problem-solving abilities, often remain. These cognitive symptoms can persist despite the use of antipsychotic medications that reduce dopamine neurotransmission, as they are not as responsive to these treatments.
While not one of the primary diagnostic criteria, cognitive symptoms are commonly recognized in people with schizophrenia. It is also noteworthy that cognitive symptoms may be present not only in patients but also among non-psychotic relatives, suggesting a potential genetic or familial link. Cognitive symptoms are not typically present solely after the first psychotic episode, as they can also develop or be present before onset.
