Understanding Rett Syndrome: Symptoms, Causes and Care

• Classic Rett Syndrome: This is the most common and well-known type. Children develop normally for the first 6 to 18 months and then gradually lose skills such as speech, purposeful hand movements, and walking.
• Atypical Rett Syndrome: Children may experience milder or more severe symptoms than those seen in classic Rett syndrome. Some children retain certain skills, while others experience faster regression.
• Congenital Rett Syndrome: Symptoms appear from birth or during the first few months of life. Infants may have poor muscle tone, feeding difficulties, and severe developmental delays.
• Late-Onset Rett Syndrome: This is a rare form in which children appear to develop normally for a longer period before symptoms such as loss of speech or purposeful hand movements begin.

• Loss of Purposeful Hand Movements: Purposeful hand use may be replaced by repetitive movements such as hand wringing, tapping, squeezing, or clapping.
• Speech Problems: Children may gradually lose the ability to speak or communicate effectively.
• Movement and Coordination Problems: Walking may become unsteady, and some children eventually lose the ability to walk.
• Breathing Abnormalities: Episodes of breath-holding, rapid breathing, hyperventilation, or irregular breathing may occur while the child is awake.
• Seizures: Many children with Rett syndrome develop epilepsy and recurrent seizures.
• Slowed Head Growth: Reduced head growth may lead to microcephaly.
• Behavioural Changes: Irritability, anxiety, social withdrawal, or reduced interest in surroundings may occur.
• Cognitive and Developmental Problems: Intellectual disability and developmental delays become more noticeable as the child grows.

• Loss of speech, purposeful hand movements, or other previously acquired skills
• Delayed development, slowed head growth, or difficulty walking
• Repetitive hand movements, behavioural changes, or feeding difficulties

• The child has a prolonged seizure or repeated seizures without recovery
• There is severe breathing difficulty, prolonged breath-holding, or bluish skin
• The child suddenly becomes unresponsive or develops a serious heart rhythm problem

• Anti-seizure medicines to control epilepsy, which is common in children with Rett syndrome.
• Medicines for breathing problems such as irregular breathing or hyperventilation.
• Behavioural and sleep medicines to reduce anxiety, improve sleep quality and manage agitation.

• Speech Therapy to help children communicate using signs, gestures or assistive devices, since verbal speech is often limited.
• Physical Therapy focuses on improving posture, muscle strength and walking ability to maintain mobility as long as possible.
• Occupational Therapy supports daily living activities and provides adaptive equipment to increase independence.
• Breathing Therapy teaches techniques that may help regulate breathing patterns and reduce complications.

• A high-calorie diet is helpful for maintaining a healthy weight since many children struggle with feeding difficulties.
• Special feeding techniques or devices for children with swallowing problems.
• Regular exercise and activity to strengthen muscles, prevent stiffness and improve circulation.

• Counselling and guidance for parents is required to help with the emotional and physical challenges of caring for a child with Rett syndrome.
• Support groups and community resources to connect families with others facing similar challenges.
• Special education programs that focus on individualised learning and developmental growth.

In the past, children with Rett syndrome were not expected to live long, but advances in healthcare have significantly improved outcomes. Today, many children with Rett syndrome live into middle or even late adulthood. Factors that influence life expectancy include:

• Heart rhythm abnormalities are one of the most serious complications and a major risk factor.
• Respiratory problems like frequent lung infections and breathing irregularities may affect survival.
• Mobility issues like children who retain some ability to walk often have better long-term health.
• Quality of care such as access to therapies, nutritional support and regular monitoring improves prognosis.

• Physical Disability: Children may gradually lose the ability to walk, use their hands effectively, or control body movements.
• Communication Barriers: Loss of speech and limited nonverbal communication can make it difficult for children to express their needs and emotions.
• Feeding Challenges: Swallowing and chewing difficulties may lead to poor nutrition and the need for special feeding techniques.
• Seizures and Breathing Problems: Epileptic seizures and irregular breathing patterns may require long-term medical management.
• Behavioural Concerns: Anxiety, frustration, agitation, and social withdrawal may occur.
• Dependence on Caregivers: Many children require long-term help with mobility, feeding, communication, and daily activities.

• Scoliosis: Many children develop curvature of the spine, which may worsen with age and require physical therapy, bracing, or surgery.
• Weak Bones: Limited mobility can reduce bone strength and increase the risk of fractures.
• Heart Rhythm Problems: Abnormal heart rhythms can be a serious complication and require regular cardiac monitoring.
• Nutritional Problems: Feeding and swallowing difficulties may make it difficult to maintain a healthy weight.
• Respiratory Infections: Breathing abnormalities and swallowing difficulties may increase the risk of chest infections.
• Sleep Problems: Some children experience disrupted sleep patterns or difficulty sleeping.

• Heart Rhythm Abnormalities: Serious cardiac rhythm problems can affect long-term outcomes.
• Respiratory Problems: Frequent lung infections and breathing abnormalities may affect health and survival.
• Mobility: Maintaining movement and physical activity can support long-term health.
• Quality of Care: Access to therapies, nutritional support, medical monitoring, and complication management can improve outcomes.
