technique that uses electrodes placed in the brain to modify brain activity by sending a constant electrical signal to the nearby nuclei. Treatment of muscle tone issues via deep brain stimulation typically targets the global pallidus and has shown to significantly improve symptoms associated with ADCP. The specific mechanism by which DBS affects ADCP is unclear. DBS of the globus pallidus interna improves dystonia in people with dyskinetic CP in 40% of cases, perhaps due to variation in basal ganglia injuries. Prognosis The severity of impairment and related prognosis is dependent on the location and severity of brain lesions. Up to 75% of patients will achieve some degree of ambulation. Speech problems, such as dysarthria, are common to these patients. References External links Cerebral palsy types Rare diseases
