Brain mapping confirms patients with schizophrenia have impaired ability to imitate
Date:3/14/2014

According to George Bernard Shaw, "Imitation is not just the sincerest form of flattery it's the sincerest form of learning." According to psychologists, imitation is something that we all do whenever we learn a new skill, whether it is dancing or how to behave in specific social situations.

Now, the results of a brain-mapping experiment conducted by a team of neuroscientists at Vanderbilt University strengthen the theory that an impaired ability to imitate may underlie the profound and enduring difficulty with social interactions that characterize schizophrenia. In a paper published online on Mar. 14 by the American Journal of Psychiatry, the researchers report that when patients with schizophrenia were asked to imitate simple hand movements, their brains exhibited abnormal brain activity in areas associated with the ability to imitate.

"The fact that patients with schizophrenia show abnormal brain activity when they imitate simple hand gestures is important because action imitation is a primary building block of social abilities," said first author Katharine Thakkar, who conducted much of the research while completing her doctoral program at Vanderbilt and is now a post-doctoral fellow at the University Medical Center in Utrecht. "The ability to imitate is present early in life and is crucial for learning how to navigate the social world. According to current theory, covert imitation is also the most fundamental way that we understand the intentions and feelings of other people."

Schizophrenia is one of the top 10 causes of disability in developed countries worldwide. It is also an extremely costly disorder. An economic study published in 2005 estimated that the overall cost of treating schizophrenia in the U.S. in 2002 was $62.7 billion. One of the main barriers to recovery for many people with schizophrenia is their profound and enduring difficulty with social interactions. This makes it difficult for them to have relation
