Cerebral palsy (CP)

The following factors can increase the likelihood of CP:

• difficult or premature birth
• twins or multiple birth
• mother’s age below 20 or over 40
• father under 20
• first child or fifth (or more) child
• baby of birth weight less than 2.5 pounds
• premature birth, less than 37 weeks

A combination of factors such as low birth weight and being a twin can increase the probability.

Symptoms of cerebral palsy normally become noticeable around 18 months to 2 years old. Although sometimes diagnosis is later in childhood. Your child might have problems with movement, co-ordination and development.

Possible signs of CP can include:

• delays in reaching development milestones
• being too stiff or too floppy
• fidgety, jerky or clumsy movements
• muscle spasms
• walking on tiptoes

Symptoms will vary depending on the severity and type of cerebral palsy.

Cerebral palsy – Symptoms (NHS)

There are 3 main types. Many people will have a mixture of these.

The Gross Motor Function Classification System shows how someone's CP might affect them.

Spastic cerebral palsy

Spasticity means the muscle tone is tight and stiff. This reduces a person's range of movement. As the muscle tone is so tight, spasticity can be very painful with muscles often going into spasm. It can affect different areas of the body.

Dyskinetic cerebral palsy

Sometimes called dystonic, athetoid or choreoathetoid cerebral palsy. Dyskinetic CP causes uncontrolled, involuntary, sustained or intermittent muscle contractions. It may be difficult to maintain an upright position. The person may find it difficult to control the tongue, vocal cords and breathing. This may affect speech and language.

Ataxic cerebral palsy

Ataxia is defined as an inability to activate the correct pattern of muscles during movement. This affects balance and spatial awareness. It can make it difficult to judge your body position in relation to things around you. Ataxia can affect the whole body. Most people with ataxia can walk but they will be unsteady with shaky movements. Ataxia can also affect speech and language.

Mixed cerebral palsy

Many people will have a mix of types.

You may also come across terms such as:

• hemiplegia (1 side of the body affected)
• diplegia (2 limbs affected)
• monoplegia (1 limb affected)
• quadriplegia (4 limbs affected)

Some people may have associated conditions; while others may not. These can include:

• learning difficulty, as children with CP cover the same range of intelligence as other children
• epilepsy, which affects up to a third of children with CP
• hearing impairment in only 8% of children
• visual impairment
• problems with sleep
• communication difficulties
• feeding difficulties
• drooling
• problems with toileting
• behaviour issues, which affect 1 in 4 children with CP
• periventricular leukomalacia (PVL)

In general, people with CP will have the same life expectancy as anyone else. CP itself is not progressive; the injury to the brain does not change. The effects may change over time for better or worse.
