London: Scientists from Weill Cornell Medical College, New York, have identified a brain chemical linked to obsessive compulsive disorder (OCD).In the study conducted using laboratory mice, researchers found that animals lacking the molecule, known as Slitrk5, exhibit behaviours similar to the human form of the condition including excessive self-grooming and increased anxiety. However, these symptoms can be eased by fluoxetine, a drug commonly prescribed to treat OCD sufferers who demonstrate bizarre behaviour which can be upsetting both to them and their families, friends and colleagues.
The researchers added: "This model can be used to further dissect the role of Slitrk5 in molecular pathways underlying the pathogenesis of obsessive-compulsive behaviours." The research appears in journal Nature Medicine. IANS
