What Is Rett Syndrome?
Rett syndrome (also called Rett disorder) is a rare neurodevelopmental disorder that affects brain growth and development. It starts in childhood, almost exclusively in girls. Its effects on brain development can affect areas such as muscle growth, walking and communication.
What Causes Rett Syndrome?
Most children diagnosed with Rett syndrome have a gene (MECP2) that changes (or mutates) and interrupts typical brain development. This mutation causes the brain to either make too little of an essential protein, or to make damaged protein the body can’t use. As a result, the brain cannot develop typically. Most cases of Rett syndrome aren’t inherited.
The condition, which can produce symptoms similar to those of autism, is linked to mutations in a gene on the X chromosome. For this reason, approximately 95 percent of children diagnosed with Rett syndrome are girls. Rett syndrome in boys is extremely rare.
Rett Syndrome Symptoms and Effects
Most infants with Rett syndrome are girls who appear to develop typically until age 2 or 3. Rett syndrome symptoms appear to progress in stages. These phases vary depending on how serious the disease is, and how far along.
Infants with Rett syndrome usually have no symptoms during the first 6 to 12 months of life. Then, during the early-onset stage (usually between 6 to 18 months), development slows or stalls. Children stop gaining developmental skills, such as walking or talking. They might also lose skills they had achieved.
Common Rett syndrome symptoms at this stage include:
- Challenging behaviors.
- Crying or irritability.
- Difficulty crawling or walking.
- Loss of, or decline in, speech skills.
- Loss of eye contact or visual interaction.
- Loss of muscle tone (muscle weakness, floppiness).
- Lack of ability to use hands effectively.
- Repetitive hand movements (wringing, washing, tapping).
- Slowed brain and head growth.
Experts believe the behavioral challenges linked to Rett syndrome might result from communication difficulties or an altered sensory system.
Because of its symptoms, Rett syndrome often gets mistaken for autism, cerebral palsy or a developmental delay. And because signs of slowed head and brain growth can be subtle, Rett syndrome might go unnoticed until other delays become obvious.
Later Stages of Rett Syndrome
As children enter their early teenage years, the effects of Rett syndrome usually slow down. Their behavior might improve, and they might cry less or be less irritable. Alertness, attention span and nonverbal communication might also improve.
However, seizures and movement problems are common. Due to immobility and muscle weakness, joint deformities and scoliosis might also arise. Many children remain at this stage for the rest of their lives.
Rett Syndrome Diagnosis and Treatment
Kids who have symptoms of Rett syndrome should see a neurologist or neurodevelopmental pediatrician for testing to determine a diagnosis.
Although there is not yet a cure for Rett syndrome, treatment can minimize its effects. As part of a comprehensive treatment plan, specialists can recommend ways to:
- Slow the loss of abilities.
- Improve or preserve movement.
- Encourage communication and socialization.
Rett syndrome treatment options might include:
- Assistive technology for custom seating and mobility equipment to improve or maintain independence.
- Braces (also known as orthoses) to help manage bone and joint deformities.
- Medicines to control seizures, reduce breathing issues, or maintain a steady heartbeat.
- Occupational therapy to improve or maintain functional hand use and ease repetitive hand movements.
- Physical therapy to improve or maintain mobility and balance.
- Speech therapy to help with nonverbal communication and social skills.
- Surgery for severe scoliosis or other joint deformities.
If your child lives with the effects of Rett syndrome, they need the support and care of a team of experts who understand this complex condition.

How a Diagnosis of Rett Syndrome Inspired a Community of Advocacy
When her daughter Amatullah was born, Bisharo Jama knew she would arrive to a loving household stocked with everything she would need, including plenty of hand-me-downs from her siblings. At a few months old, Amatullah seemed just as chubby, beautiful and healthy as her siblings were at her age. But then she started to change in ways Bisharo never anticipated.
