Which statement regarding the pathophysiology and etiology of schizophrenia is correct?
A)"Brain imaging shows that there is reduced blood flow to the thalamus, frontal lobe, and temporal lobes."
B)"There is an increased number of nicotinic receptors in the hippocampus, which makes it harder to form new memories and interpret sensory stimuli."
C)"Genetics does not seem to factor into the cause of the disease."
D)"The ventricles and sulci of the brain are decreased in size."

A)There are many abnormalities of the central nervous system in a client with schizophrenia. Brain imaging studies of individuals with schizophrenia consistently reveal a pattern of structural abnormalities that include decreased volumes of gray matter in the prefrontal cortex, temporal lobes, hippocampus, and thalamus; enlarged ventricles and sulci; and decreased blood flow to the frontal lobe, thalamus, and temporal lobes. A decreased number of nicotinic receptors in the hippocampus makes it harder for the client with schizophrenia to form new memories and interpret sensory stimuli. Genetics seems to factor into the cause of the disease, as familial patterns of the disease are noted. In the client with schizophrenia, the ventricle and sulci of the brain are increased in size.
