CP affects the part of the brain that controls muscle movements. The majority of children with cerebral palsy are born with it, although it may not be detected until months or years later. The early signs of cerebral palsy usually appear before a child reaches 3 years of age. The most common are a lack of muscle coordination when performing voluntary movements (ataxia); stiff or tight muscles and exaggerated reflexes (spasticity); walking with one foot or leg dragging; walking on the toes, a crouched gait, or a "scissored" gait; and muscle tone that is either too stiff or too floppy. Other neurological symptoms that commonly occur in individuals with CP include seizures, hearing loss and impaired vision, bladder and bowel control issues, and pain and abnormal sensations. A small number of children have CP as the result of brain damage in the first few months or years of life, brain infections such as bacterial meningitis or viral encephalitis, or head injury from a motor vehicle accident, a fall, or child abuse. The disorder isn't progressive, meaning that the brain damage typically doesn't get worse over time. Risk factors associated with CP do not cause the disorder but can increase a child's chance of being born with the disorder.CP is not hereditary.
Causes and Risk Factors
Cerebral palsy is caused by damage to the fetal or infant brain. It occurs when there is neurological damage before, during, or within five years of birth that prevents the brain from developing properly. Damage to the parts of the brain that control motor function causes children with CP to struggle with posture, balance and movement. Although this disability affects muscle movement, it isn't caused by problems with the actual muscles or nerves-it is strictly caused by developmental brain damage.
Common Causes of Cerebralstrongalsy:
- Bacterial and viral infections.
- Bleeding in the brain (hemorrhaging).
- A lack of oxygen to the brain before, during or after birth (asphyxia).
- Prenatal exposure to drugs and alcohol, mercury poisoning from fish and toxoplasmosis.
- Head injuries sustained during birth or in the first few years of infancy.
