Possible Causes

Cerebral Palsy (CP) is a group of conditions affecting control of movement and posture. The characteristics of CP may vary widely between individuals depending on the degree and location of brain damage. Symptoms may range from mild to severe, and diagnostic techniques can help determine the extent of the condition.

While most doctors, nurses, midwives, and hospital technicians provide a high standard of care for their patients, unfortunately, many families are harmed by medical mistakes. Parents of a child suffering with Cerebral Palsy should contact an experienced Cerebral Palsy lawyer to research the cause of their child’s condition. Medical mistakes are responsible for many birth injury cases and it would be impossible for a parent, alone, to determine if medical malpractice caused their child's injury. It is only through the dedicated and thorough efforts of a legal and medical team that the cause can be ascertained.

Risk Factors

Risk factors are variables that have been observed to have an effect on the diagnosis of medical conditions. Risk factors do not, by themselves, indicate that a condition will occur, nor does the lack of a risk factor mean that a condition will not occur. The presence of risk factors may simply point to an increased likelihood, not a certainty, for the development of Cerebral Palsy.

The following risk factors in parents, may increase the risk of Cerebral Palsy (CP) in their child:

If the Mother is over 40 years old, or younger than 20 years old;
If the Father is younger than 20 years old;
African-American ethnicity. Cerebral Palsy has a higher rate of incidence within the African-American community.

The following risk factors related to pregnancy or the delivery, may increase the risk of CP:

If the pregnancy is the first, or is the fifth or later in the family;
Twinning, or multiple child pregnancy, can lead to lower birth weights and/or prematurity, increasing the risk for CP;
Vaginal bleeding in the third trimester;
Low birth weight - under 5.7 pounds;
Premature birth, less than 37 weeks;
Breech birth;
Fetal Distress, respiratory or vascular problems during delivery;
Low Apgar score. Infant heart rate, breathing, muscle tone, reflexes, and skin color are each scored as 0 (low), 1 (intermediate), or 2 (normal) after delivery. A total score of 7-10 at 5 minutes is considered normal; 4-6, intermediate; and 0-3, low. Scores that remain low 10-20 minutes after delivery indicate increased risk for CP.

Additional risk factors for Cerebral Palsy include:

Rh or ABO blood type incompatibility between mother and child;
Serious viral infections (ex., German Measles) during early pregnancy;

Cerebral Palsy Symptoms

Cerebral Palsy syndromes are grouped into four main categories: spastic, athetoid, ataxic, and mixed forms. Each type is characterized by different symptoms:

Spastic Cerebral Palsy - occurs in about 70% of cases. The spasticity is due to upper motor neuron involvement and may mildly or severely affect motor function. The syndrome may produce hemiplegia, paraplegia, quadriplegia, or diplegia.

Affected limbs usually are underdeveloped and show increased deep tendon reflexes, weakness, and a tendency toward contractures. A scissors gait and toe walking are characteristic. In mildly affected children, impairment may occur only during certain activities (eg, running). With quadriplegia, an associated impairment of oral, lingual, and palatal movement, with consequent dysarthria, is common.

Athetoid Cerebral Palsy - occurs in about 20% of cases. Slow, writhing, involuntary movements may affect the extremities (athetoid) or the proximal parts of the limbs and the trunk (dystonia); abrupt, jerky, distal movements (choreiform) also may occur. The movements increase with emotional tension and disappear during sleep. Dysarthria occurs and is often severe.

Ataxic Cerebral Palsy - occurs in about 10% of cases. Weakness, incoordination, and intention tremor produce unsteadiness, a wide-based gait, and difficulty with rapid or fine movements.

Mixed CP is not uncommon, and is a combination of the above types but is most often a mixture of spasticity and athetoid movements, with tight muscle tone and involuntary reflex.

Symptoms of Cerebral Palsy may be evident immediately after birth, or may take months or years (1,200 - 1,500 preschool children are diagnosed each year), to become noticeable. Parents may notice that their child is slow to reach developmental milestones or displays abnormal behavior.

At 3 months there may be a lack of facial expressions, the baby may not respond to some sounds, or is unable to follow movement with their eyes.
The child may not be able to bring their hands together at 4 months.
A child with Cerebral Palsy may not display the coordination to lift their head, or rollover at 6 months.
At 8 months the baby may not be able to sit up by themselves, or without support. There may be a head lag when the child is placed in a sitting position.
By 12 months the child may not be able to crawl.
Drooling is a common problem because of the lack of facial and muscle control.
Muscle tremor or spasticity may be evident, with a tendency of infants to tuck their arms in toward their sides, scissors movements of the legs, or other abnormal movements.
Feeding may be a continuous effort and problematic.
Excessive stiffness when dressing, changing diapers, or bathing.

It is important to realize that the presence of any of these symptoms does not necessarily indicate your child has Cerebral Palsy. Children develop on different timeframes, and symptoms are often outgrown. Only your doctor can make an accurate diagnosis and provide you with the information you need to care for your child.

Diagnosis

The diagnosis of Cerebral Palsy includes the consideration and monitoring of many factors, and may not be made until after the first or second years of development. A child's brain and central nervous system have an amazing ability to recover completely, or partially, following injury - this sometimes leads to a delay in diagnosis. In addition, children develop at different rates, and motor skill difficulties can frequently be signs of other problems - misdirecting diagnosis. In most cases, an interdisciplinary team of medical professionals will be gathered to review the child's strengths and weaknesses, test results, risk factors and medical history. Based on these numerous criteria, a diagnosis of Cerebral Palsy may be made.

Several tests can be used to assist in the diagnosis, and determine the severity of Cerebral Palsy:

Intelligence tests often are administered to a child with CP to evaluate mental impairment;
An electroencephalogram (EEG) traces electrical activity in the brain and can reveal patterns that suggest a seizure disorder;
Imaging tests are helpful in diagnosing hydrocephalus, structural abnormalities, and tumors. This information can help the physician assess the child's long-term prognosis;
Magnetic resonance imaging (MRI) uses a magnetic field and radio waves to create pictures of the internal structures of the brain. This study is performed on older children. It defines abnormalities of white matter and motor cortex more clearly than other methods.

Cerebral Palsy diagnosis depends on many factors, a team of medical professionals can make an accurate diagnosis, and assist in determining a long-term prognosis for the child. While a medical diagnosis can be determined, often what caused the Cerebral Palsy cannot be, read more about Cerebral Palsy Causes.

Parents of a child suffering with Cerebral Palsy should contact an experienced Cerebral Palsy lawyer to research the cause of their child’s condition. Haste is essential. Litigation may be the only way to receive compensation to which you may be entitled. Such compensation will likely include lost wages, medical bills, and/or financial compensation to heirs (in the case of a wrongful death).
