Schizophrenia is a chronic and severe mental disorder that affects how a person thinks, feels and behaves. People with schizophrenia may seem like they have lost touch with reality and symptoms include: hallucinations, delusions and thought and movement disorders. Because the causes of schizophrenia are still unknown, treatments focus on eliminating the symptoms of the disease. Clinical trials now in phase 3 show the potential of artemisinin and artesunate in eliminating said symptoms.
