That is how schizophrenia works: auditory hallucinations, confusion, inability to tell what is real and what is not. Schizophrenia isn’t something a person can simply ignore. You can’t get rid of that voice, or even the voices on your own. But what causes this problem? That was the question researchers wanted to tackle.
