Short answer

b. positive; negative

Step-by-step solution

Understand Symptoms of Schizophrenia

Schizophrenia has two main categories of symptoms: positive and negative. Positive symptoms include hallucinations, delusions, and thought disorders. Negative symptoms involve diminished emotional expression, lack of motivation, and withdrawal from social activities.

Differentiate Drug Effectiveness

Both traditional and atypical antipsychotic drugs are known to be more effective at treating positive symptoms such as hallucinations and delusions. However, they are generally less effective at addressing negative symptoms like lack of motivation and social withdrawal.

Analyze the Options

Given the knowledge that antipsychotics work best on positive symptoms and are less effective on negative symptoms, analyze the answer choices: - a. negative; positive - b. positive; negative - c. cognitive; emotional - d. emotional; cognitive

Select the Correct Answer

The correct answer must reflect that antipsychotics primarily improve positive symptoms and have limited efficacy on negative symptoms. Therefore, the correct choice is option b: positive; negative.

Key concepts

Positive Symptoms

In schizophrenia, positive symptoms refer to excesses or exaggerations of normal functions. These symptoms heighten perception and can distort reality. They are called "positive" because they add something to a person's normal experience. Some common positive symptoms include:

• Hallucinations: These are sensory experiences that appear real but are created by the mind. A person may see or hear things that aren't present.
• Delusions: These are strong beliefs that are unlikely to be true and often involve misinterpretations of reality.
• Thought Disorders: These can involve unusual or dysfunctional ways of thinking, such as having trouble organizing thoughts or making connections between ideas.

Positive symptoms are often more noticeable and can significantly interfere with daily functions. However, they are also more responsive to treatment with antipsychotic drugs. Understanding these symptoms helps in effectively targeting them in therapeutic settings.

Negative Symptoms

Negative symptoms of schizophrenia represent a loss of normal function rather than an addition like positive symptoms. These symptoms often make it difficult for individuals to perform typical daily activities and can severely impact quality of life. Key negative symptoms include:

• Diminished Emotional Expression: This involves a reduction in the expression of emotions in the face, voice tone, or lack of gestures and movements normally used to convey emotions.
• Lack of Motivation: Described as avolition, this entails a severe lack of enthusiasm or desire to engage in purposeful activities.
• Social Withdrawal: Individuals may begin to avoid social interactions, leading to increased isolation.

Negative symptoms are generally tougher to treat with antipsychotic medications compared to positive symptoms. This is because there's often minimal response to drugs; thus, psychosocial interventions are crucial in managing these symptoms.

Antipsychotic Drugs

Antipsychotic drugs are primarily used to treat schizophrenia and other mental health conditions. They function by altering the effects of neurotransmitters in the brain, such as dopamine. The key facts about antipsychotic drugs include:

• Traditional Antipsychotics: These are also known as first-generation antipsychotics. They are more effective in treating positive symptoms but often come with substantial side effects like muscle stiffness or tremors.
• Atypical Antipsychotics: Also called second-generation antipsychotics, these tend to have fewer side effects while still being effective in addressing positive symptoms. They also attempt to manage negative symptoms, but often with limited success.
• Treatment Approach: While medication is crucial for managing symptoms, a comprehensive treatment plan including therapy and social support is often necessary to improve overall well-being.

Despite their effectiveness on positive symptoms, both traditional and atypical antipsychotics have limited impact on negative symptoms. They are essential in forming a part of a broader treatment strategy that involves different therapeutic approaches and support systems.
