It is well established that a mood disorder can increase an individual's risk for substance abuse, but there is also evidence that the converse is true; substance abuse can increase a person's vulnerability to stress-related illnesses. Now, a new study finds that repeated cocaine use increases the severity of depressive-like responses in a mouse model of depression and identifies a mechanism that underlies this cocaine-induced vulnerability. The research, published by Cell Press in the August 25 issue of the journal Neuron, may guide development of new treatments for mood disorders associated with substance abuse.
