Researchers, Using Light to Activate Neurons, Make Mice Obsessive, or Not
Two teams of researchers have pinpointed some of the neural circuitry that underlies compulsive grooming behaviors. The discoveries, reported in Science on Thursday, could guide new treatments for people with obsessive-compulsive disorder, autism, and other conditions that exhibit symptoms of repetitive and compulsive actions.
Using so-called optogenetics techniques, which precisely control neuron activity with light, one of the groups induced repetitive grooming behaviors by stimulating a neural circuit known to be overactive in OCD patients. The obsessive grooming behaviors persisted ...

Depression Raises Stroke Risk in Younger Women
Being depressed is known to increase the risk for stroke. Now a new study suggests that the association is even stronger in younger women.
Australian researchers studied 10,457 women, average age 52, without a history of stroke, surveying them every three years for 12 years. Using a well-validated depression scale, they found that about 24 percent were depressed at each survey. The study, published online this month in the journal Stroke, found 177 strokes over the study period.
Being depressed nearly doubled the risk for ...

CBT Researchers Work with Memory to Combat Compulsive Checking
Concordia University-Montreal psychology professor, Adam Radomsky, is working with Gillian Alcolado, a PhD candidate in clinical psychology, on an important study of how CBT can be used to help to tap into false beliefs about one’s memory, and thereby reverse an often debilitating symptom of OCD: compulsive checking.
Research has shown that low confidence in one’s memory can be a factor that causes checking. In order to reduce compulsive checking, Alcolado and Radomsky came up with ...
