Cerebral Palsy: What, Why and How?
Thursday, January 12th, 2012Cerebral palsy is a brain disorder that affects as many as 2 to 3 children per 1,000. Loosely translated into “brain paralysis”, cerebral palsy, or CP is the leading cause of childhood disability involving function and development.
Signs and Symptoms
Cerebral palsy is caused by brain damage that cannot be reversed and has no cure. Parents may begin to notice various signs that their child is failing to meet certain key developmental milestones.
Those targets may include:
- Problems maintaining head movements after 2 months
- Pulling one side of the body while crawling or not being able to sit up by themselves by 10-12 months
Other noticeable medical issues associated with CP might include the inability to crawl or stand with support following their first birthday or not being able to walk after 2 years.
Issues with Muscle Tone
Other signs and symptoms of cerebral palsy might include problems with muscle tone, reflexes and posture.
For example, the most identifiable sign of cerebral palsy is harm to muscle tone. This relates to muscles working together by sustaining correct resistance.
The body works and moves by muscles synchronizing with other muscles and this frequently occurs in pairs. In other words as some muscles contract, others relax. Even something as simple as raising an arm necessitates coordination of many muscles; some bending while others relax. The brain injury or irregularity that resulted in cerebral palsy impairs the nervous system to manage muscle movement.
Problems With Posture
Cerebral palsy also affects posture and balance. Indications that something is awry might become noticeable as a baby begins to sit up and learns to move about. Normal posture is symmetrical.
For instance, an infant in a sitting position would normally have both legs in front of them and when bent or curved, they copy or mirror each other. But with irregular or uneven posture, this is not the case. In fact, parents or caregivers might notice that especially with hip-joints, one area will twist or curve inward, while the other side will turn outward.
What caused my baby’s cerebral palsy?
Cerebral palsy stems from damage to various parts of the baby’s still-developing brain. This type of harm can occur early in the mother’s gestational period. It can also occur as the infant is working its way through the birth canal. As many as 10 percent of cerebral palsy cases begin as the baby makes its way through the birth canal. However, the majority of cerebral palsy cases actually begin before the baby is born.
Risk Factors
As the baby grows in the mother’s womb, certain risk factors can develop. It is important that doctors closely monitor mother and baby during pregnancy.
Some of the risk factors include anything from infection and seizures to something known as Rh factor incompatibility. This refers to a difference or discrepancy in the blood between mom and baby that can actually cause cognitive damage.
