- fear of loud sounds or physical contact
- limited intellect
- problems drawing or writing
- problems paying attention
- worrying too much
Medical problems of someone with Williams syndrome might include:
- narrowing of the blood vessels leaving the heart, which can cause high blood pressure and heart failure
- high calcium levels in the blood, which may cause seizures and rigid muscles
- limited movement of the joints

Young children with Williams syndrome have distinctive facial features, including:
- a broad forehead
- a short nose with a broad tip

There is neither a cure for Williams syndrome nor a standard course of treatment. Treatment is given for symptoms as needed. Most people with Williams syndrome need to live with a caregiver.
