Schizophrenia is a mental disease that appears with different symptoms: hallucinations, delusions, changes in behaviour, muddled thoughts based on hallucinations or delusions.
This disease, which is very serious and equally affects men and women, is frequently treated with antipsycotich drugs and they can be classified in different groups depending on their mechanism of action. This is related to their chemical structure and the consequent interaction with correspondent receptors.
