Excerpt from Paralysis and Other Diseases of the Nervous System in Childhood and Early Life It must also be remembered that there is a large class of diseases met with in children, the so-called birth palsies. Under this name are included many varieties of paralysis having the one characteristic in common that they date from birth. Some no doubt arise during intra uterine life from some condition of unknown nature interfering with the development of cerebral structures. Some probably result from maternal conditions, detachments of the placenta. Some are probably to be traced somewhat indefinitely to maternal ill health or injury. A certain number also probably arise as a result of injury during a long and difficult, or at least an abnormal, labour and the physical condition in these cases may be associated with varying degrees of mental defect.
