Answer:
Scientists in Italy discovered that patients suffering from obsessive-compulsive disorder (OCD) and people in love have similarities in their brain activity. Both groups showed increased activity in the caudate nucleus, an area of the brain that is involved in reward and motivation. Dr. Fischer, a researcher in this field, concludes that these findings suggest that there may be a connection between OCD and romantic love, and that studying this connection further could lead to new treatments for OCD. As Dr. Fischer states in an interview with CNN, “If we can learn what makes someone fall in love, we can learn how to help someone with OCD.”
