Common symptoms of cerebral palsy

The most common signs of cerebral palsy typically appear between 12 and 18 months of age, and are classified as either physical or neurological in nature. Parents should monitor for any of the following red flags.

These cerebral palsy symptoms present differently in each child, depending on the type, location, and extent of brain damage. They can range from muscle issues and movement limitations to speech and vision difficulties. A combination of any of the below should prompt a call to your child’s doctor.

Common physical symptoms

Physical (motor) signs of cerebral palsy often cause issues with coordination, muscle composition or control, and balance. Physical symptoms may include:

Common neurological symptoms

Neurological symptoms relate to issues of the nervous system and brain, often affecting learning, communication or the senses. Neurological symptoms include:

It’s important to notify your child’s pediatrician if you detect any of these symptoms. Early detection of CP can be crucial in managing the condition effectively.

Spotting the early signs of cerebral palsy

One of the earliest red flags is delayed developmental milestones. If a baby isn’t rolling over, sitting up, crawling, or taking first steps within the typical age range, it may signal underlying issues with muscle control, coordination, or balance.

When a baby’s development doesn’t follow the expected path, it can be unsettling — especially if the signs are subtle. But in the case of cerebral palsy, early detection can make a world of difference.

4 early signs of cerebral palsy

Physical signs can vary, but common early indicators include:

  • Unusual posture, like a persistently arched back
  • Stiff or floppy limbs that appear tense or unusually limp
  • A tendency to favor one side of the body
  • Feeding difficulties such as trouble sucking, swallowing, or prolonged mealtimes

Parents might also notice motor delays, such as a baby struggling to grasp objects or bring their hands to their mouth — small actions that require fine-tuned motor control.

Even visual tracking issues, excessive fussiness, or weak reflexes can point to something more serious. These aren’t just developmental detours — they can be early clues that the brain’s motor pathways aren’t developing as they should.

Not every delay is a sign of cerebral palsy — babies grow at their own pace, and many catch up just fine. Some symptoms can also point to other conditions that look similar to CP. But if your instincts say something is off, trust them. Timely consultation with a healthcare professional can lead to early intervention, which is critical in improving long-term outcomes.

When medical errors lead to cerebral palsy

Sadly, not every case of cerebral palsy is a natural occurrence. Too often, it results from avoidable medical malpractice — mistakes made during pregnancy, labor, or delivery that end in lifelong consequences for a child.

Cerebral palsy caused by medical negligence typically stems from a breakdown in the standard of care. Common causes of cerebral palsy linked to medical mistakes include:

These aren’t rare accidents — they are lapses in judgment or protocol by professionals trained extensively to avoid them. It’s not uncommon for doctors to evade questions about what went wrong, or for parents never to receive a full explanation of their child’s injury.

If you suspect mistakes occurred during your delivery, it’s important to speak with a qualified birth injury lawyer. The Cerebral Palsy Center has lawyers who can review your case today at no cost.

Cerebral palsy symptoms at different ages

Cerebral palsy can show up in different ways depending on your child’s age. Knowing what to look for at each stage helps you act early — when intervention matters most.

If something feels off in your child’s development, trust your instinct and notify their doctor. The following symptoms should raise concern at each age group.

Symptoms in babies under 3 months

0–3 months
  • Struggling to hold their head up when lying on their back or being picked up
  • Muscles that seem overly tight or stiff
  • Limbs that feel unusually soft or floppy
  • Crossing legs when picked up
  • Pushing away from you rather than snuggling in

Symptoms after 6 months

6 months

By this stage, most babies are starting to explore their movement. Signs of concern include:

  • Inability to roll over from back to front or vice versa
  • Not bringing hands together or to the mouth
  • Reaching consistently with only one hand, while the other stays clenched in a fist

Symptoms in toddlers after 12 months

12 months

Older babies should be gaining independence in how they move and explore. Concerning signs include:

  • Using only one side hand or leg to crawl
  • Crawling crooked or dragging hands or limbs
  • Sliding on buttocks or hopping on knees instead of crawling on all fours

For a fuller walkthrough of what to expect at this stage, see our guide on cerebral palsy symptoms in toddlers.

Symptoms in children aged 2–3

2–3 years

By age 2 to 3, signs of cerebral palsy primarily appear as delays in reaching normal milestones of development, movement, or communication:

  • Muscle stiffness or floppiness
  • Weak arm or leg muscles
  • Jerking or uncontrolled movements
  • Tremors or spasms
  • Difficulty speaking or hearing
  • Walking on tiptoes

Not every unusual movement indicates cerebral palsy. However, if you notice patterns that don’t match typical developmental timelines, schedule an evaluation as soon as possible. Early cerebral palsy diagnosis leads to better long-term outcomes.

Cerebral palsy is a lifelong condition, so for what to expect beyond childhood, see cerebral palsy symptoms in adults and how CP symptoms progress over time.

Symptoms of cerebral palsy by type

Cerebral palsy is a broad diagnosis that shows up differently depending on which areas of the brain are affected. Understanding the types of cerebral palsy is key to recognizing the condition and getting the right treatment as early as possible.

The four main types — spastic, ataxic, athetoid (dyskinetic), and hypotonic — each carry distinct symptoms. Some individuals are diagnosed with mixed cerebral palsy, a combination of more than one type.

75–85%
Spastic — most common type
~10%
Athetoid / dyskinetic type
5–10%
Ataxic — rarest type
Most common · 75–85%

Spastic cerebral palsy

Caused by damage to the motor cortex, spastic CP leads to increased muscle tone, making movement stiff and jerky.

  • Stiff or tight muscles, especially in arms and legs
  • Awkward or scissored walking pattern
  • Difficulty with fine motor tasks like writing
  • One-sided weakness (hemiplegia) or stiffness in both legs (diplegia)
Athetoid / dyskinetic

Dyskinetic cerebral palsy

Caused by damage to the basal ganglia, this type leads to involuntary, uncontrolled movements. Muscle tone shifts between too tight and too loose.

  • Involuntary movements in the face, arms, or trunk
  • Facial grimacing or drooling due to poor oral motor control
  • Difficulty with feeding, speaking, and breathing rhythmically
  • Muscle tone that fluctuates throughout the day
Hypotonic

Hypotonic cerebral palsy

Characterized by decreased muscle tone, hypotonic CP can be particularly difficult to diagnose in infancy.

  • Very loose, floppy muscles
  • Delayed head control or inability to sit without support
  • Poor reflexes and reduced muscle strength
  • Slow motor skill development
Rarest type

Ataxic cerebral palsy

Stems from damage to the cerebellum, the part of the brain that controls coordination and balance.

  • Poor balance and unsteady gait
  • Shaky hands or tremors when reaching for objects
  • Trouble with depth perception
  • Slurred or slow speech (ataxic dysarthria)

Mixed cerebral palsy symptoms

Mixed CP occurs when damage affects multiple brain areas, producing a blend of symptoms from different types. The most common mix is spastic-dyskinetic. Symptoms can involve muscle stiffness paired with involuntary movements, fluctuating tone across different muscle groups, and complex challenges with walking, balance, and coordination. Each case is unique.

Symptoms of conditions associated with cerebral palsy

Cerebral palsy rarely presents on its own. The brain injuries that cause CP can also lead to associated conditions — called comorbidities — that affect learning, behavior, communication, and sensory processing. Fortunately, most can be managed effectively with the right care plan.

Screening for these coexisting disorders is just as important as treating cerebral palsy itself. Common conditions associated with CP include:

If your child has been diagnosed with cerebral palsy, make sure they are also screened for these additional challenges. Early, coordinated care involving doctors, therapists, and educators can dramatically improve outcomes. For a fuller walkthrough of cognitive, emotional, sensory, and behavioral effects, see our guide on non-motor symptoms of cerebral palsy.

Less common symptoms of cerebral palsy

While most people associate cerebral palsy with challenges in movement, balance, or speech, there are many other symptoms of CP that are less commonly known.

Children affected by cerebral palsy can also experience:

Parents should monitor for any combination of these symptoms and notify their child’s doctor with concerns. Early detection greatly improves treatment outcomes.

Financial assistance from a cerebral palsy claim

According to some estimates, the lifetime cost of care for a child with cerebral palsy can reach as high as $1.7 million. Even with health insurance, Medicaid, and community grants, there is often a significant gap left for families to cover.

Common financial challenges for families include:

That’s why it’s essential to explore every possible form of financial support. Families may be eligible for disability benefits and some are entitled to substantial compensation through a birth injury lawsuit, especially if their child’s cerebral palsy was caused by a medical mistake.

Doctors and hospitals carry malpractice insurance for this exact reason — to compensate families when negligent care leads to permanent injury. Our lawyers have helped thousands of families recover compensation to cover therapy, equipment, schooling, and more.

Frequently asked questions about cerebral palsy symptoms

Children with cerebral palsy may start to show physical or neurological signs in the first 12 months. However, CP is usually not formally diagnosed until age 2 to 3, when doctors can determine whether a child has missed key developmental milestones like rolling over, sitting, crawling, or walking.

The hallmark symptom of cerebral palsy is difficulty with movement and coordination. Among the various motor challenges, spasticity — stiff muscles and exaggerated reflexes — is the most commonly reported, affecting around 75–85% of those diagnosed. It causes tight, rigid limbs, jerky or awkward movements, and trouble with balance and posture. The severity varies widely: some may have a slight limp while others require full-time support.

Children who have experienced the brain injury that leads to cerebral palsy may start to show symptoms of motor delay within the first 12 months. Parents can look for signs as early as 6 months, including tight or weak muscles, crossing legs when picked up, pushing away from parents, inability to roll over, or poor head control.

Cerebral palsy is a nonprogressive condition — the underlying brain damage does not worsen over time. However, symptoms can change as a person ages. Some may worsen due to functional impairments or secondary conditions; others may improve as children adapt to assistive devices, therapy, and advancing technology. Early intervention through consistent therapy is the most effective way to improve long-term function.
