Abstract
We present a short review on dielectric susceptibility properties of quasi one-dimensional charge and spin density waves. Emphasis is made on new features we have observed in recent measurements performed at very low frequencies and at low temperatures: a critical slowing down of the real part of the dielectric susceptibility towards a temperature $T_{\rm g}$ and the bifurcation between two relaxation time processes near $T_{\rm g}$. We interpret these data as resulting from a transition of the charge and the spin density wave into a glassy-like state.
