Conditions We Treat in Autism and Developmental Disabilities (CADD)


22q Deletion

The 22q11.2 deletion syndrome is a condition caused by a missing section of chromosome 22.

Pediatric Angelman Syndrome

Pediatric Angelman Syndrome (AS) is a genetic condition characterized by problems learning and thinking, delays in developing speech/language, difficulty controlling and coordinating muscle movements, seizures, and a happy, easily excited disposition.

Pediatric Autism Spectrum Disorder

Autism Spectrum Disorder affects every child differently. This means that people may present with either very mild difficulties or very severe difficulties, with a wide range of severity between those two extremes. Along with deficits in social communications, individuals with ASD may have restricted, repetitive patterns of behavior, interests or activities.

Brain Injuries

Some children acquire damage to their brains over the course of childhood due to a car accident, severe fall, or other serious event. The term Traumatic Brain Injury (TBI) is used to describe a sudden trauma to the head, such as when the head violently hits an object or an object breaks the skull and enters brain tissue.

Pediatric Cerebral Palsy

Pediatric Cerebral Palsy is a disorder of movement, muscle tone or posture that is usually caused by damage to the brain before birth.

Developmental Delay or Regression

Medical experts have developed checklists of “developmental milestones.” These milestones describe skill sets that children should meet by certain ages. Your child’s ability to crawl, sit up, speak, and hold objects—and even throw tantrums—are a few examples. If your child doesn't seem to be meeting the averages, it’s possible that they may be affected by a condition called developmental delays.

Pediatric Down Syndrome

The Down Syndrome Clinic at Children’s Health℠ Specialty Center Dallas Campus is designed to serve all the health needs of children with Down syndrome.


Pediatric epilepsy causes a child to have repeated seizures, which can vary in type, duration and frequency over time. Learn more about what to expect with this condition.

Fragile X Syndrome

Fragile X syndrome (FXS) is a genetic or hereditary disorder passed down from parent to child. FXS is the most common cause of inherited intellectual and developmental disabilities.

Intellectual Disability

Intellectual disability is a term used when a person has difficulty with certain skills such as communicating, taking care of him or herself, and social skills. A child with an intellectual disability learns and develops more slowly than a typical child.

Lysosomal Storage Disease

Lysosomal Storage Diseases are a group of about 50 disorders, characterized by a build-up of toxic materials in the body’s cells of the skeleton, skin, brain, heart and nervous system.

Neurofibromatosis (NF)

Neurofibromatosis causes tumors to grow on nerve tissue throughout the body. Learn how these tumors can affect hearing, vision, the heart and more.

Phelan-McDermid Syndrome

Phelan-McDermid Syndrome (Deletion 22Q13) is a genetic condition associated with delays in language, motor, and social development.

Pitt Hopkins Syndrome

Pitt Hopkins Syndrome is a rare genetic disorder that causes many symptoms, including intellectual disability, gastrointestinal issues, and seizures.

Speech and Language Impairment

Children who have difficulty producing speech or communicating with others may be diagnosed with a Specific Language Impairment (SLI).

Pediatric Turner Syndrome

Pediatric Turner Syndrome (TS) is caused by rare chromosomal abnormalities of the XX chromosome. Learn about Turner Syndrome symptoms & causes with Children's Health.

Williams Syndrome

Williams syndrome is a rare genetic disorder that can lead to problems with development. Symptoms of Williams Syndrome include delays in development of speech, difficulty paying attention, feeding problems, problems with thinking and learning, and short stature.
