Study Notes

Rett Syndrome

A rare genetic disorder affecting mostly females, causing a mutation on the X chromosome, impacting brain development.
Presents with normal development until 6-18 months of age, then regression occurs.
No cure exists, management focuses on symptom control and a multidisciplinary approach.

Causes

Mutations in the Methyl CpG binding protein 2 (MeCP2) gene on the X chromosome.
The MeCP2 gene is responsible for producing a protein essential for brain development.
Mutations disrupt normal nerve cell function, leading to the characteristic symptoms.

Diagnostic Criteria

Normal prenatal and perinatal development.
Normal psychomotor development during the first few months after birth.
Normal head circumference at birth.
Onset of the following after the period of normal development:
- Deceleration of head growth between 5 and 48 months.
- Loss of previously acquired purposeful hand skills between 5 and 30 months, with development of stereotyped hand movements like hand-wringing or hand-washing.
- Loss of social engagement early on, though social interaction may develop later.
- Appearance of poorly coordinated gait or trunk movements.
- Severely impaired expressive and receptive language development, leading to severe psychomotor retardation.

Stages of Rett Syndrome

Stage 1 (6-18 months): Slowing of head growth after 5 months, lack of eye contact, diminished interest in toys, repetitive hand movements, crawling without hand use, ability to walk.
Stage 2 (1-4 years): Rapid deterioration phase with severe speech impairment, loss of motor functions, frequent hand stereotypes, sleep disturbances, and muscle tone loss.
Stage 3 (2-10 years): Plateau phase marked by apraxia (loss of ability to execute movements), gastrointestinal disorders, seizures, and behavioral improvements like less irritability and crying.
Stage 4 (after 10 years): Late Motor Deterioration phase with potential loss of mobility, decreased hand gestures, and development of scoliosis and muscle inflexibility.

Co-morbidities

Gastrointestinal problems.
Epilepsy, often appearing around the age of 3.
Scoliosis, increasing in frequency with age, particularly during puberty.

Outcome Measure

The Rett Syndrome Gross Motor Scale, a 45-point assessment tool measuring various motor tasks such as sitting, standing, walking, and running.
Scoring ranges from 0-3, with higher scores indicating greater independence.

Management

Physical Therapy: Aims to improve mobility, balance, coordination, posture, reduce apraxia through repetitive movements, and increase cardiovascular fitness.
Occupational Therapy: Addresses stereotypic hand movements, promotes hand use, and supports self-care activities.
Speech and Language Therapy: Focuses on non-verbal communication, augmentative and alternative communication (AAC), and addressing swallowing difficulties.
Environmental Modifications: Adapting the environment with items like specialized chairs, tables, and toilets.
Medications: Anticonvulsants for seizures, medications for breathing problems, constipation, reflux, and anti-arrhythmic drugs for heart rhythm issues.
Nutritional Supplements: To help with weight gain.
Parental Counseling: Provides support and guidance.
