Final answer:
Atypical antipsychotics are used to treat both the negative and 1) positive signs of schizophrenia.
Step-by-step explanation:
Schizophrenia is a mental illness characterized by symptoms such as hallucinations, delusions, inappropriate emotional responses, and difficulty thinking. These symptoms are referred to as positive symptoms because they represent an excess or distortion of normal functioning. Atypical antipsychotics work by blocking dopamine receptors in the brain, which helps reduce the positive symptoms of schizophrenia.
For example, medications such as risperidone and olanzapine are commonly prescribed to manage the positive symptoms of schizophrenia. These medications can help alleviate hallucinations and delusions, allowing individuals with schizophrenia to experience a clearer perception of reality. Therefore the correct answer is 1) Positive.
