What schizophrenic symptoms are primarmily decreased by drugs that selectively block the d2 dopamine receptor?
delusions and hallucinations so-called "positive" symptoms
Exercise therapy has been shown to improve positive and negative symptoms, cognition, and improve quality of life. Aerobic exercise has been shown to improve cognitive deficits of working memory and attention. Exercise has also been shown to increase the volume of the hippocampus in those with schizophrenia. A decrease in hippocampal volume is one of the factors linked to the development of the disease. However, there still remains the problem of increasing motivation for, and maintaining participation in physical activity. Supervised sessions are recommended.

The first-line treatment for schizophrenia is an antipsychotic. The first-generation antipsychotics, now called typical antipsychotics, are dopamine antagonists that block D2 receptors, and affect the neurotransmission of dopamine. Those brought out later, the second-generation antipsychotics known as atypical antipsychotics, can also have effect on another neurotransmitter, serotonin. Antipsychotics can reduce the symptoms of anxiety within hours of their use but for other symptoms they may take several days or weeks to reach their full effect.[36][184] They have little effect on negative and cognitive symptoms, which may be helped by additional psychotherapies and medications.
