We provide a condition under which a version of Shannon's entropy power inequality will hold for dependent variables. We first provide a Fisher information inequality extending that found in the independent case. The key ingredients are a conditional expectation representation for the score function of a sum, and the de Bruijn identity which relates entropy and Fisher information.
