The central nervous system 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 neurologic disorders. Although neuronal dysregulation is causative of symptoms that 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 central nervous system physiology; therefore, it stands to reason that dysregulation of normal astrocyte function contributes to the etiology and progression of varied neurologic disorders. We review here some neurologic disorders associated with an astrocyte factor and discuss how the related astrocyte dysfunction contributes to the etiology or progression of these disorders or both.
