Cerebral palsy
Cerebral palsy (CP) is a group of disorders that affect movement, balance and posture because of abnormal development of, or damage to, the developing brain. The underlying brain injury does not progressively worsen, although a person’s needs and symptoms can change over time.

Names & terminology
How this entity may be named or searched
- Canonical name
- Cerebral palsy
- Abbreviation
- CP
- Important distinction
- CP is an umbrella term for a group of movement/posture disorders rather than one single uniform disease.
- Subtype terms
- Spastic, dyskinetic, ataxic and mixed CP describe patterns/subtypes, not synonyms for all CP.
Structured entity profile
Clinical profile
What is cerebral palsy?
Cerebral palsy is a group of disorders affecting the ability to move and maintain balance and posture. It results from abnormal brain development or damage to the developing brain. CP is the most common motor disability in childhood. [1]
Signs and patterns
Signs vary from person to person and can include delayed movement milestones, abnormal muscle tone, stiffness, involuntary movements, poor coordination, difficulty walking, and problems with balance or posture. Some people have additional epilepsy, vision, hearing, learning or communication difficulties. [1]
SYMPTOM MATRIX
How cerebral palsy may present
Signs differ with age, CP type and severity; developmental surveillance is important.
- Delayed motor milestones
- Abnormal muscle tone
- Stiff or floppy movements
- Persistent movement or posture differences
- Balance or coordination difficulty
- Involuntary movements
- One-sided movement preference
- Feeding or speech difficulty
- Seizures
- Vision, hearing or learning problems
- New seizure or prolonged seizure
- Breathing or swallowing difficulty
- Sudden loss of function
- Severe unexplained pain or acute illness
CP itself is not progressive; a sudden new loss of function should prompt evaluation for another cause.
Screening and diagnosis
Diagnosis can involve developmental monitoring, formal developmental screening and detailed medical/developmental evaluation. Brain imaging, EEG, genetic or metabolic testing may be used when clinicians need to investigate the cause or exclude other conditions. CP is often diagnosed in the first or second year of life, although milder cases may take longer to confirm. [2]
During assessment I take a detailed pregnancy, birth and neonatal history, while remembering that cerebral palsy can have several causes and that a specific cause is not always identifiable.
Diagnostic pathway
How cerebral palsy is identified
Developmental monitoring and structured evaluation are used to identify motor differences and define support needs.
CDC emphasizes developmental monitoring, screening and evaluation rather than a single diagnostic test.
Treatment and support
There is no cure, but early identification and intervention can improve function and quality of life. Support may include physical, occupational and speech therapy, medicines for specific symptoms, mobility or communication devices, orthopedic care and educational services. [3]
Ongoing care is multidisciplinary. Vision and psychological well-being deserve attention alongside motor function, communication and rehabilitation needs.
Treatment & care hub
Care focuses on function, participation and associated conditions
CP treatment is multidisciplinary and changes with age, goals and functional needs.
Physical & occupational therapy
Movement, strength, positioning, self-care and participation are common therapy goals.
Speech / feeding support
Speech-language and feeding therapy may be needed.
Medicines
Medicines may be used for spasticity, seizures, pain or other associated problems.
Equipment & surgery
Orthoses, mobility devices and orthopedic or other procedures may be considered.
There is no cure for CP, but treatment and support can improve function and quality of life.
Does cerebral palsy get worse?
The underlying brain abnormality or injury that causes CP does not progressively worsen. However, the way CP affects movement, pain, joints, mobility or daily function can change across childhood and adult life, so ongoing review and support may still be needed. [1]

Persistent or significant delay in movement milestones is an important clue. Mild cerebral palsy can be harder to recognize and may not become clear until a child is older.
