Rett syndrome
Rett syndrome is a rare genetic neurodevelopmental disorder, most commonly affecting girls. It causes severe impairment in speech, movement, and cognitive development.
Symptoms usually appear between 6 and 18 months of age, after a period of apparently typical early development.
🧬 Cause
Rett syndrome is caused by a spontaneous mutation in the MECP2 gene.
- Usually occurs randomly (de novo mutation)
- Affects brain development and nerve signalling
- Not inherited in most cases
🧠 Key Symptoms
🗣️ Loss of skills
- Loss of spoken language
- Loss of purposeful hand use
✋ Hand movements
- Hand-wringing
- Clapping
- Tapping
- “Washing” motions
- Hands often move to mouth
🚶 Movement difficulties
- Walking problems
- Stiff muscles (spasticity)
- Toe walking
🧠 Brain and growth changes
- Slowed head growth (microcephaly)
- Loss of developmental skills
👁️ Communication and social behaviour
- Loss of speech
- Strong eye contact (“eye pointing”) used for communication
- Autistic-like withdrawal
🌬️ Breathing issues
- Breath-holding
- Hyperventilation
- Swallowing air
⚠️ Other symptoms
- Seizures
- Sleep problems
- Teeth grinding
- Scoliosis
📈 Stages of Progression
Stage I – Early Onset (6–18 months)
- Subtle developmental slowing
- Low muscle tone
- Reduced eye contact
Stage II – Rapid Regression (1–4 years)
- Loss of speech
- Loss of hand skills
- Noticeable regression
Stage III – Plateau (2–10 years)
- Some behavioural stabilisation
- Motor difficulties continue
- Eye contact may improve
Stage IV – Late Motor Deterioration
- Reduced mobility
- Muscle weakness
- Scoliosis
- Cognition often remains stable
💡 Key Message
Rett syndrome is a lifelong condition caused by a genetic mutation, with changing physical and developmental effects over time.
💊 Management
There is no cure, but support includes:
- Physiotherapy
- Speech and communication support
- Seizure management
- Mobility support
- Specialist care
Most individuals survive into adulthood with appropriate care.
🧩 2. EASY READ VERSION (SIMPLE LANGUAGE)
🧠 Rett Syndrome
- Rett syndrome is a rare condition
- It mostly affects girls
- It starts in early childhood
🧬 What causes it
- A change in a gene called MECP2
- It happens by chance
- It is not anyone’s fault
🗣️ What happens
Children may:
- Lose speech
- Lose hand skills
- Have trouble moving
✋ Hand movements
People may:
- Wring their hands
- Clap or tap
- Put hands to their mouth
🚶 Other changes
- Walking may be difficult
- Muscles may be stiff
- Head growth may slow
🌬️ Breathing
Some people may:
- Hold their breath
- Breathe fast
- Have irregular breathing
💡 Key message
- Rett syndrome is lifelong
- People need support
- Communication is still possible
