<P> Athetoid cerebral palsy or dyskinetic cerebral palsy (sometimes abbreviated ADCP) is primarily associated with damage to the basal ganglia in the form of lesions that occur during brain development due to bilirubin encephalopathy and hypoxic - ischemic brain injury . ADCP is characterized by both hypertonia and hypotonia, due to the affected individual's inability to control muscle tone . Clinical diagnosis of ADCP typically occurs within 18 months of birth and is primarily based upon motor function and neuroimaging techniques . Athetoid dyskinetic cerebral palsy is a non-spastic, extrapyramidal form of cerebral palsy . Dyskinetic cerebral palsy can be divided into two different groups; choreoathetoid and dystonic . Choreo - athetotic CP is characterized by involuntary movements most predominantly found in the face and extremities . Dystonic ADCP is characterized by slow, strong contractions, which may occur locally or encompass the whole body . </P> <P> Mixed cerebral palsy has symptoms of athetoid, ataxic and spastic CP appearing simultaneously, each to varying degrees, and both with and without symptoms of each . Mixed CP is the most difficult to treat as it is extremely heterogeneous and sometimes unpredictable in its symptoms and development over the lifespan . </P> <P> Because the causes of CP are varied, a broad range of preventative interventions have been investigated . </P> <P> Electronic fetal monitoring has not helped to prevent CP, and in 2014 the American College of Obstetricians and Gynecologists, the Royal Australian and New Zealand College of Obstetricians and Gynaecologists, and the Society of Obstetricians and Gynaecologists of Canada have acknowledged that there are no long - term benefits of electronic fetal monitoring . Prior to this, electronic fetal monitoring was widely used to prop up obstetric litigation . </P>
