Many neurological conditions are caused by damage to neurons and glial cells. For most of these diseases there are at present no effective treatments to minimise the extent of neuronal and glial loss, and no effective way of replacing what has been lost. This picture is rapidly changing. This book describes the various conditions that lead to damage to the nervous system, and the ways in which they may be ameliorated. It covers the burgeoning science of reconstruction of the nervous system, through neuronal, glial and stem cell transplantation, axon regeneration, remyelination, plasticity and pharmacological interventions.
