Cerebral palsy causes : The cerebral palsies of childhood comprise a group of conditions which may be either of intra-uterine onset, or which are acquired during parturition or at a still later period. Cases of intra-uterine origin are usually developmental in character, and to this group belong porencephalia, agenesis corticalis and other defects, although evidences of hæmorrhage and sclerotic changes, as a result of traumatism, fœtal meningo-encephalitis and syphilis, have been observed in rare instances. The cerebral palsies encountered later in child-life are the result of either hæmorrhage, embolism or thrombosis.
