Description	The fourth-order neutral differential equation with damping term is investigated. There are given conditions that are optimal in a certain sense, guaranteeing the oscillation of all proper solutions. The continuability of solutions and the existence of nonoscillatory bounded solutions are investigated as well. Some results are new for equation without delays.
