Symptoms:

Symptoms of cerebral palsy can be very different between people with this group of disorders. Symptoms may:

• Be very mild or very severe
• Only involve one side of the body or both sides
• Be more pronounced in either the arms or legs, or involve both the arms and legs

Symptoms are usually seen before a child is 2 years old, and sometimes begin as early as 3 months. Parents may notice that their child is delayed in reaching, and in developmental stages such as sitting, rolling, crawling, or walking.

There are several different types of cerebral palsy. Some people have a mixture of symptoms.

Symptoms of spastic cerebral palsy, the most common type, include:

• Muscles that are very tight and do not stretch. They may tighten up even more over time.
• Abnormal walk (gait): arms tucked in toward the sides, knees crossed or touching, legs make "scissors" movements, walk on the toes
• Joints are tight and do not open up all the way (called joint contracture)
• Muscle weakness or loss of movement in a group of muscles (paralysis)
• The symptoms may affect one arm or leg, one side of the body, both legs, or both arms and legs

The following symptoms may occur in other types of cerebral palsy:

• Abnormal movements (twisting, jerking, or writhing) of the hands, feet, arms, or legs while awake, which gets worse during periods of stress
• Tremors
• Unsteady gait
• Loss of coordination
• Floppy muscles, especially at rest, and joints that move around too much

Other brain and nervous system symptoms:

• Decreased intelligence or learning disabilities are common, but intelligence can be normal
• Speech problems (dysarthria)
• Hearing or vision problems
• Seizures
• Pain, especially in adults (can be difficult to manage)

Eating and digestive symptoms

• Difficulty sucking or feeding in infants, or chewing and swallowing in older children and adults
• Problems swallowing (at all ages)
• Vomiting or constipation

Other symptoms:

• Increased drooling
• Slower than normal growth
• Irregular breathing
• Urinary incontinence

Signs and tests:

A full neurological exam is critical. In older people, testing cognitive function is also important.

The following other tests may be performed:

• Blood tests
• CT scan of the head
• Electroencephalogram (EEG)
• Hearing screen
• MRI of the head
• Vision testing
