🧬 What is Down's Syndrome? understanding trisomy 21

Down's syndrome (also known as Trisomy 21) is a genetic condition caused by the presence of an extra copy of chromosome 21. It is the most common chromosomal condition, affecting approximately 1 in 700 babies born worldwide.

Key facts:

• Down's syndrome is not a disease or an illness — it's a natural part of human diversity.
• It occurs randomly at conception and is not caused by anything parents did or didn't do.
• While there is no "cure," early intervention and support can help children with Down's syndrome thrive and reach their full potential.
• People with Down's syndrome have a wide range of abilities — each person is unique.

Types of Down's syndrome:

• Trisomy 21 (95%): Three copies of chromosome 21 in every cell.
• Translocation (3-4%): Part of chromosome 21 attaches to another chromosome.
• Mosaic Down's syndrome (1-2%): A mix of cells with and without the extra chromosome.

⚕️ Characteristics & Features common traits

While every person with Down's syndrome is unique, there are some common physical and developmental characteristics:

Physical features may include:

• Flattened facial profile and small nose
• Upward-slanting eyes with epicanthic folds
• Small ears and mouth
• Short neck and small hands with a single transverse palmar crease
• Short stature and low muscle tone (hypotonia)
• Increased flexibility in joints

Developmental and health considerations:

• Mild to moderate intellectual disability
• Delayed speech and language development
• Fine and gross motor delays
• Increased risk of certain health conditions: heart defects, hearing loss, vision problems, thyroid issues, and sleep apnoea
• Earlier onset of Alzheimer's disease in adulthood

Strengths often include: Warm and engaging personalities, strong social skills, empathy, and persistence.

🔍 Prenatal & Early Signs detection and diagnosis

Down's syndrome can be identified before or after birth. Early detection allows families to prepare and access early intervention.

Prenatal screening and diagnostic tests:

• Screening tests (non-invasive): Ultrasound (nuchal translucency), maternal blood tests (first and second trimester screening), and cell-free DNA testing (NIPT).
• Diagnostic tests (confirmatory): Chorionic villus sampling (CVS) at 10-13 weeks, amniocentesis at 15-20 weeks.

At birth, signs may include:

• Low muscle tone (hypotonia) — babies may feel "floppy"
• Excess skin at the nape of the neck
• Distinctive facial features
• Heart murmur (present in about 50% of babies with Down's syndrome)
• Difficulty feeding (due to low muscle tone)

A chromosomal analysis (karyotype) is performed to confirm the diagnosis and determine the type of Down's syndrome.

🩺 Diagnosis & Health Monitoring comprehensive care

After a diagnosis is confirmed, ongoing monitoring by a multidisciplinary team is essential to support health and development.

Recommended health monitoring includes:

• Newborn/Infancy: Echocardiogram (heart), hearing test, vision screening, thyroid function test, and feeding assessment.
• Childhood: Regular growth monitoring, hearing and vision checks, dental care, and developmental surveillance.
• Adolescence/Adulthood: Thyroid screening, sleep studies (for sleep apnoea), mental health monitoring, and Alzheimer's screening.

At Gabriella Centre, we work closely with:

• Paediatricians and geneticists
• Cardiologists, ENT specialists, and ophthalmologists
• Physiotherapists, occupational therapists, and speech therapists
• Psychologists and social workers

This collaborative approach ensures every child receives comprehensive, coordinated care.

🛠️ Support & Intervention empowering potential

Early intervention is crucial for children with Down's syndrome. Our centre offers a wide range of services tailored to each child's needs:

• Early Intervention (0-3 years): Physiotherapy to address low muscle tone, occupational therapy for sensory and fine motor skills, and speech therapy to support early communication.
• Physiotherapy: To improve strength, coordination, balance, and motor milestones. Includes exercises to support gross motor development (crawling, walking, running).
• Occupational Therapy: To develop fine motor skills, handwriting, daily living skills, and sensory processing.
• Speech & Language Therapy: To support communication, articulation, language comprehension, and alternative communication methods (AAC, signing).
• Feeding Therapy: To address difficulties with sucking, swallowing, and eating due to low muscle tone.
• School Support: Collaboration with schools to ensure appropriate educational accommodations, individualised learning plans, and social inclusion.
• Health Monitoring: Regular check-ups to manage associated health conditions.
• Family Support: Counselling, support groups, and resources for families and siblings.

Our approach: We celebrate every child's uniqueness and work with families to build skills, confidence, and independence. We focus on strengths and potential — not limitations.
