Cerebral palsy (CP) is an umbrella term encompassing a group of non-progressive, non-contagious motor conditions that cause physical disability in human development, chiefly in the various areas of body movement. Cerebral refers to the cerebrum, which is the affected area of the brain (although the disorder probably involves connections between the cortex and other parts of the brain such as the cerebellum), and palsy refers to disorder of movement. Furthermore, paralytic disorders are not cerebral palsy the condition of quadriplegia, therefore, should not be confused with spastic quadriplegia, nor tardive dyskinesia with dyskinetic cerebral palsy, nor diplegia with spastic diplegia, and so on. Cerebral palsy's nature as an umbrella term means it is defined mostly via several different subtypes, especially the type featuring spasticity, and also mixtures of those subtypes.
