Narrator: This is Science Today. Although there are drugs that can alleviate the disturbing hallucinations and delusions of schizophrenia, Karen Schmidt, a biological anthropologist at the University of California, found that many patients still have trouble getting along in society because of whatís called "emotional flattening".
Schmidt: And this has a number of manifestations. One that I was interested in was the loss, or the relative lack of facial expression and non-verbal gestural expression in people with schizophrenia.
Narrator: In a series of cross-cultural studies, Schmidt found that people react negatively towards those who have this lack of facial movement.
Schmidt: Itís a very hard to live in society when you have basic problems with social interaction. When people find you to be strange when youíre speaking to them and it causes very severe problems for people with schizophrenia. If in some way they could be solved or people could be educated about the specific difficulties, then maybe we could reduce a lot of the stress and a lot of the emotional pain that people with schizophrenia go through.
