Sep. 4, 2013 — Because animals can’t talk, researchers need to study their behavior patterns to make sense of their activities. Now researchers at Tel Aviv University are using these zoological methods to study people with serious mental disorders.Prof. David Eilam of TAU’s Zoology Department at The George S. Wise Faculty of Life Sciences recorded patients with obsessive-compulsive disorder and “schizo-OCD” — which combines symptoms of schizophrenia and OCD — as they performed basic tasks.

They noted that the behavioral differences identified in the study could be used to help diagnose patients with OCD and other obsessive-compulsive disorders, including schizo-OCD.The taxonomy of mental disorders”I realized my methodology for studying rat models could be directly applied to work with humans with mental disorders,” Prof. Eilam said. “Behavior is the ultimate output of the nervous system, and my team and I are experts in the fine-grained analysis of behavior, be it of humans or of other animals.”The main features of OCD are, of course, obsessions and compulsions.
