a sychological disorder that interests me

schizophrenia is the sychological disorder that interests me because i can't find any explanation for how people can hear voives to which the people can't hear.schizophrenia is a mental disorder that makes difficulty to tell the difference between reality and unreality.and the patients always insist and say that what they think or hear is true.so,i think that schizophrenia is different from the other mental illnesses and it is a type of madness or loss of mind.i hope to find an interpretation logically of this illness.in additions, the sychologists are also confused of the causes and the treatments of this type of disorders.
