The central nervous system (CNS) is comprised of numerous cell types that work in concert to facilitate proper function and homeostasis. Disruption of these carefully orchestrated networks results in neuronal dysfunction, manifesting itself in a variety of neurological disorders. While neuronal dysregulation is causative of symptoms manifest in the clinic, the etiology of these disorders is often more complex than simply a loss of neurons or intrinsic dysregulation of their function. In the adult brain, astrocytes comprise the most abundant cell type and play key roles in CNS physiology, therefore it stands to reason that dysregulation of normal astrocyte function contributes to the etiology and progression of varied neurological disorders. We review here some neurological disorders associated with an astrocyte factor and discuss how the related astrocyte dysfunction contributes to the etiology and/or progression of these disorders.
