In this paper, the qualitative properties of solutions for a kind of non-autonomous third-order neutral delay differential equations (NDDEs) are discussed. New results on the stability, boundedness and square integrability of solutions and their derivatives are obtained by using the method of Lyapunov functional. Our results generalize and extend many related results on third-order neural differential equations with and without delay in the literature. Moreover, an example is given to show the correctness and feasibility of the main results.
