Final answer:
Schizophrenia can present both negative and postive symptoms. Negative symptoms, associated with chronic Schizophrenia, present as flattened emotional states and don't usually respond to medication. Positive symptoms, associated with acute Schizophrenia, present as hallucinations or delusions and do respond to medications.
Step-by-step explanation:
A person with schizophrenia who exhibits negative symptoms may have an expressionless face and toneless voice. These symptoms characterize a flattened emotional state, lack of pleasure, and basic drives. These symptoms are most common with chronic schizophrenia and are not likely to respond to drug therapy. Negative symptoms reflect a decrease or absence in certain behaviors, emotions and drives. Those with positive symptoms, on the other hand, are likely to experience hallucinations and delusions. These individuals are typically diagnosed with acute schizophrenia, which usually respond more positively to drug therapy.
