Cerebral palsy is common yet still has no known cure
About 2.1 in every thousand live births involve cerebral palsy, the most common childhood movement disorder. Damage or disrupted development in motor-control brain regions—usually before birth—leaves lasting limits on posture and movement, though supportive care can still change daily life.
Cerebral palsy is a group of early-childhood movement disorders. Signs vary and can include poor coordination, stiff or weak muscles, and tremors, sometimes with sensory, vision, hearing, or speech problems. Infants may miss milestones such as rolling, sitting, crawling, or walking. The formal definition stresses permanent, non-progressive disturbances in the developing fetal or infant brain that limit activity through disordered movement and posture.
Causes are abnormal development or injury to motor, balance, and posture circuits, most often prenatally, sometimes during or soon after birth; many cases have no identified trigger. Subtypes track dominant features: spastic (stiff muscles), ataxic (poor coordination), and dyskinetic (writhing movements). Diagnosis follows developmental assessment; blood tests and imaging mainly exclude other conditions. Maternal immunization and child head-injury prevention can avert some causes. Physical, occupational, and speech therapy, medication, and surgery help individuals function; there is no known cure.
Hippocrates described related problems in the fifth century BCE; nineteenth-century work by William John Little made spastic diplegia long known as Little's disease. It remains the most common childhood movement disorder, appearing in about 2.1 of every thousand live births. The primary neurological lesion stays fixed, while high tone can drive progressive orthopedic issues as muscle-tendon units and bones grow unequally. Severely affected newborns may look very floppy or very stiff and may have associated birth defects such as spinal curvature or a small head. Symptoms can emerge or shift with age rather than appearing all at once at birth.
