Cerebral Palsy Birth Injury Claims: What Families Should Know

Cerebral palsy (CP) is the most common motor disability of childhood — and one of the most misunderstood conditions in birth injury law. Some CP cases stem from preventable oxygen deprivation during delivery. Many do not. Understanding which story the medical evidence supports is the first step for any family wondering whether a legal claim is possible.

What cerebral palsy is

The CDC defines cerebral palsy as “a group of disorders that affect a person’s ability to move and maintain balance and posture,” caused by “abnormal brain development or damage to the developing brain that affects a person’s ability to control their muscles.” The name breaks down simply: “cerebral” refers to the brain, “palsy” to weakness or problems using the muscles.

Several facts from the CDC are worth absorbing early, because they shape realistic expectations:

• CP does not worsen over time, though the exact symptoms can change across a person’s lifetime.
• There is no cure, but treatment — medicines, surgery, braces, physical, occupational, and speech therapy — can improve quality of life, especially when started early.
• Severity varies enormously. A person with mild CP might walk a little awkwardly without special help; a person with severe CP might need special equipment to walk or need lifelong care.
• Related conditions are common, including intellectual disability, seizures, and problems with vision, hearing, or speech.

The latest CDC tracking data show about 2.4 out of every 1,000 U.S. children aged 8 years have CP, monitored through the CDC’s Autism and Developmental Disabilities Monitoring (ADDM) Network.

Types of cerebral palsy

Doctors classify CP by the main type of movement disorder involved. The CDC describes four main types:

• Spastic CP — the most common type, affecting about 80% of people with CP. Muscles are stiff, making movements awkward. It is further described by body area: diplegia (mainly legs), hemiplegia (one side of the body), or quadriplegia (all four limbs, the trunk, and the face — the most severe form).
• Dyskinetic CP — problems controlling movement of the hands, arms, feet, and legs; movements are uncontrollable, slow and writhing or rapid and jerky. Muscle tone can swing between too tight and too loose, even within a single day.
• Ataxic CP — problems with balance and coordination; unsteady walking and difficulty with precise movements like writing.
• Mixed CP — symptoms of more than one type, most commonly spastic-dyskinetic.

The type and severity matter legally because they drive the child’s lifelong care needs — and care needs drive the economic damages a claim seeks to recover. Our guide to life care plans explains how experts project those needs.

What causes CP — and how often birth plays a role

This is the section that matters most, so read it carefully. The CDC states that people “used to think that CP was mainly caused by lack of oxygen during the birth process” but that “now, scientists think that this causes only a small number of CP cases.”

The numbers behind that statement:

• The majority of CP — 85% to 90% — is congenital, meaning it relates to brain development or damage that occurred before or during birth, and in many cases the specific cause is never identified.
• A small percentage is acquired CP, caused by brain damage more than 28 days after birth — usually from infection (such as meningitis) or head injury.
• The abnormal brain development or damage can happen before birth, during birth, within a month after birth, or during the first years of life while the brain is still developing.

Known risk factors for congenital CP include being born too early or too small, multiple birth, maternal infection during pregnancy, and complications during birth — but risk factors are not causes, and most children with risk factors do not develop CP.

The honest takeaway: most CP is not caused by medical negligence. Any article or advertisement suggesting otherwise is selling something. A claim exists only in the minority of cases where the evidence specifically ties the child’s CP to substandard care.

When CP may support a birth injury claim

A cerebral palsy claim is viable when medical experts can connect the child’s condition to a breach of the standard of care during pregnancy, labor, or delivery. The scenarios attorneys investigate most often include:

• Prolonged oxygen deprivation (perinatal asphyxia). Fetal monitoring showed distress — persistent decelerations, loss of variability — and providers failed to respond appropriately, or delayed a needed C-section. NOLO identifies perinatal asphyxia as a central issue in birth-related malpractice claims, noting that severe oxygen deprivation can lead to brain damage.
• Delayed emergency delivery. Clear indications for immediate delivery were present, but the delivery was delayed without justification, and the child suffered a brain injury consistent with that delay. See our article on delayed C-section claims.
• Mismanaged maternal conditions. Preeclampsia, infection, or other pregnancy complications that the standard of care required providers to detect and treat — and that foreseeably endangered the baby’s brain.
• Traumatic delivery injuries. In some cases, mechanical trauma during a difficult delivery contributes to brain injury.

In each scenario, the legal work is the same: prove the standard of care, the breach, the injury, and causation — with causation being, as NOLO notes, “a problem in birth-related malpractice cases much more often than in other kinds of personal injury claims.” Our article on oxygen deprivation at birth covers the delivery-room medicine behind these cases.

When the evidence points away from negligence

Families deserve honesty about the other side of the ledger. A CP claim is unlikely to succeed when the evidence shows:

• The CP stems from a prenatal developmental cause — genetics, early-pregnancy infection, or abnormal brain formation — that no delivery-room decision could have changed.
• The delivery records show providers recognized problems promptly and responded according to accepted practice, but the outcome was poor anyway.
• Imaging and expert review place the brain injury’s timing well before labor began.
• The specific cause cannot be determined at all. Without a demonstrable breach and a causal link, there is no claim — however devastating the diagnosis.

This is why reputable birth injury attorneys have cases screened by independent medical experts before filing. A good attorney will tell you when the evidence does not support a claim. That answer is painful, but it is far better than years of litigation built on hope rather than evidence.

What a CP claim seeks to cover

When a CP claim does move forward, compensation aims to fund the child’s needs over a lifetime. NOLO explains that compensatory damages include economic damages (medical bills, therapy, equipment, lost earning capacity) and noneconomic damages (pain and suffering, loss of enjoyment of life), with many states capping noneconomic damages.

For CP specifically, the largest component is usually future care: physical, occupational, and speech therapy; assistive technology and mobility equipment; home modifications; specialized education support; and attendant care. Life care plans — detailed projections prepared by medical and economic experts — are how attorneys quantify these needs. Because the child is a minor, courts typically must approve any settlement and the funds are protected in trusts or structured settlements, as our guide to how settlements are paid explains.

Frequently asked questions

My child was diagnosed with CP at age 2. Is it too late to ask questions?

Not necessarily. CP is often diagnosed in early childhood as missed motor milestones become clear, and many states extend filing deadlines for minors. But deadlines still exist and vary by state — get a legal opinion promptly rather than assuming you have time.

Does a CP diagnosis mean someone is at fault?

No. Most CP has no negligent cause. A diagnosis is a medical finding, not a legal conclusion. Only expert review of the pregnancy and delivery records can assess whether substandard care played a role.

What records will an attorney want to see?

Prenatal records, fetal monitoring strips, labor and delivery notes, neonatal records, and brain imaging (MRI/CT). The attorney’s medical experts use these to reconstruct what happened and when.

Can CP be caused by something that happened after birth?

A small percentage of CP is acquired after birth — usually from infection like meningitis or from head injury more than 28 days after birth. Those cases raise different legal questions than delivery-room claims.

Will my child need to be involved in the legal process?

Generally no. A parent or guardian ad litem represents the child’s interests, and the child’s participation is not required. Courts protect minors’ interests by reviewing settlements before they become final.
