What Is Cerebral Palsy? Understanding the Different Types

Cerebral palsy (CP) is the most common physical disability that begins in childhood. It is a neurological condition caused by damage to the developing brain, usually before birth, during birth, or shortly after birth. While cerebral palsy affects movement, muscle tone, posture, and coordination, it is not a progressive disease. The brain injury does not worsen over time, although the way it affects a person’s body may change with age.

Every person with cerebral palsy is unique. Some people walk independently, while others use wheelchairs. Some need little assistance with daily activities, while others require significant support. Cerebral palsy does not define a person’s intelligence, personality, or potential. Many people with CP become teachers, parents, athletes, business owners, advocates, artists, and leaders in their communities.

What Causes Cerebral Palsy?

Cerebral palsy occurs when the developing brain is injured or does not develop normally. Some possible causes include:

• Lack of oxygen to the brain before or during birth
• Premature birth
• Low birth weight
• Infections during pregnancy
• Stroke before or shortly after birth
• Head injury during infancy (less common)

In many cases, the exact cause is never identified.

The Four Main Types of Cerebral Palsy

1. Spastic Cerebral Palsy

Spastic cerebral palsy is the most common type, affecting about 80% of people with CP.

People with spastic CP have increased muscle tone, causing muscles to feel tight or stiff. This can make walking, reaching, writing, or completing everyday tasks more difficult.

Spastic CP may affect:

• One side of the body (hemiplegia)
• Mainly the legs (diplegia)
• All four limbs (quadriplegia)

2. Dyskinetic (Athetoid) Cerebral Palsy

Dyskinetic cerebral palsy causes involuntary movements that a person cannot control. These movements may be slow and twisting or sudden and jerky.

People may have difficulty with:

• Speaking clearly
• Swallowing
• Fine motor tasks
• Controlling facial muscles

Stress, excitement, or fatigue often make the movements more noticeable.

3. Ataxic Cerebral Palsy

Ataxic CP primarily affects balance and coordination.

People with ataxic CP may:

• Have an unsteady walk
• Struggle with precise hand movements
• Have difficulty judging distance
• Experience shaky movements

This is the least common form of cerebral palsy.

4. Mixed Cerebral Palsy

Many people have symptoms from more than one type of cerebral palsy. This is called mixed CP.

The most common combination is:

• Spastic and dyskinetic (athetoid)

Because everyone’s brain injury is different, no two people experience cerebral palsy in exactly the same way.

Common Challenges

Depending on the individual, cerebral palsy may also affect:

• Speech
• Swallowing
• Vision or hearing
• Balance
• Fine motor skills
• Daily living activities

Some people also experience seizures, chronic pain, or fatigue, while others do not.

Treatment and Support

Although there is no cure for cerebral palsy, many treatments help people live full and independent lives.

These may include:

• Physical therapy
• Occupational therapy
• Speech therapy
• Assistive technology
• Mobility equipment such as walkers or wheelchairs
• Medications to reduce muscle tightness
• Surgery when appropriate

Support should focus not only on physical needs but also on education, employment, relationships, and community inclusion.

Living Beyond the Diagnosis

A diagnosis of cerebral palsy is not a prediction of what someone can achieve. With support, determination, and opportunities, people with CP pursue higher education, raise families, build careers, travel, advocate for change, and contribute to their communities in countless ways.

The most important thing to remember is that cerebral palsy affects movement—not a person’s worth, dreams, or ability to make a difference.

When society focuses on accessibility, inclusion, and high expectations instead of limitations, people with cerebral palsy have the opportunity to thrive.
