What Other Conditions Often Occur Alongside Rett Syndrome?

When you understand Rett Syndrome, you also want to know what else might travel alongside it — so nothing catches your family off guard.

In short

Rett Syndrome rarely walks alone. Because it affects how the brain and nervous system develop, several conditions commonly occur alongside it — most often epilepsy (seizures), breathing irregularities, scoliosis (spinal curving), movement and muscle-tone difficulties, feeding and gut challenges, and sleep disturbance. Knowing these can occur means a well-planned care team can watch for them early and support your child proactively, not reactively.

What often occurs alongside Rett Syndrome

• Seizures / epilepsy — very common, often appearing in early childhood; any suspected seizure needs prompt medical (neurology) review, not therapy first.
• Breathing irregularities — breath-holding, hyperventilation or air-swallowing, usually while awake.
• Scoliosis — curving of the spine that often progresses with age and needs orthopaedic monitoring.
• Movement and hand differences — loss of purposeful hand use with repetitive hand movements (wringing, mouthing), and changes in muscle tone or walking.
• Feeding, swallowing and gut issues — reflux, constipation, and difficulty chewing or swallowing affecting nutrition and growth.
• Sleep disturbance — irregular sleep patterns, night-time waking or laughing.
• Communication and motor challenges — these shape day-to-day support and are where structured developmental therapy helps most.

Not every child experiences all of these, and their pattern and intensity vary widely. The value of knowing is simple: a coordinated team can screen, anticipate and act early.

The Pinnacle way

A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an app, a checklist or online. From there, your family gets a coordinated plan that supports communication, movement and daily living while medical needs like seizures are managed by the right specialists. Learn more about Rett Syndrome, how occupational therapy supports hand use and daily skills, and what the AbilityScore is and how it is formed.

Next step — If your child shows any of these signs, or you simply want a clear starting point, book a developmental check with a Pinnacle clinician.
