About Down Syndrome

Know the facts. Challenge the myths.

Down syndrome is a genetic condition. With awareness, healthcare and inclusion, individuals living with it lead full and meaningful lives.

The Facts

Down syndrome is a genetic condition caused by the presence of an extra copy of chromosome 21. Normally every person inherits 46 chromosomes; individuals with Down syndrome have 47. This additional genetic material changes the way the body and brain develop, leading to differences in physical features, health, and learning.

The Causes

Down syndrome occurs when a baby is born with an extra chromosome 21. This happens randomly during cell division and is not caused by anything parents did or did not do. In most cases it is not inherited — only certain forms (translocation) can be passed down in families.

Types of Down Syndrome

About 95%

Trisomy 21

The most common type. Every cell in the body has an extra chromosome 21.

3–4%

Translocation

Extra chromosome 21 material attaches to another chromosome. Can sometimes be inherited.

1–2%

Mosaic

Some cells have three copies of chromosome 21, others the usual two. Often milder features.

Risk Factors & Detection

  • Parental age: The chance rises with age — about 1 in 940 at 30, increasing to 1 in 85 by age 40.
  • Genetic translocation: Families with a history of translocation have a slightly higher risk.
  • No lifestyle cause: Down syndrome is not caused by diet, behaviour or environment.
  • Screening tests: Blood tests and ultrasound (nuchal translucency) estimate risk during pregnancy.
  • Diagnostic tests: Amniocentesis and chorionic villus sampling provide accurate diagnoses.
  • In Ghana: Prenatal screening services are limited, so many families learn of the condition after birth.

Life Expectancy

Improved medical care has increased average lifespan from 10 years in the 1960s to 47 years by the 2010s. With timely healthcare, therapy and family support, many individuals with Down syndrome live long, meaningful lives.

Key Facts in Ghana

The realities families face — and the gaps DSAG is working to close.

Prevalence

More than 35,000 individuals in Ghana live with Down syndrome (about 1 in every 1,000 people).

Healthcare Challenges

Many children experience congenital heart defects and immune issues; access to specialised therapies remains limited.

Education

Teachers often lack training to support learners with Down syndrome, and implementation of inclusive education policies remains weak.

Stigma & Social Barriers

Cultural misconceptions still isolate families. Awareness and advocacy remain critical to changing attitudes.

Laws & Policies

Ghana has progressive disability rights frameworks, but enforcement and everyday implementation lag behind.

Urban-Rural Gap

Most specialised institutions are concentrated in Accra, Kumasi and other cities, leaving rural families with limited access.

Why Inclusion Matters

When persons with Down syndrome are given equal opportunities, they thrive in schools, workplaces and communities. Inclusion benefits everyone.

Inclusion is Justice

Inclusion recognizes the inherent dignity of every person — it ensures individuals with Down syndrome are active participants in society. True inclusion is not charity; it is justice.

Stronger Communities

Communities thrive when everyone is valued. Inclusion fosters empathy, acceptance and unity.

Unlocking Potential

Every person with Down syndrome has unique talents. Inclusion allows those abilities to be discovered, nurtured and celebrated.

Breaking Stigma

Inclusion challenges harmful stereotypes and shifts the narrative from limitation to possibility.

Driving Change

Inclusion inspires innovation in education, healthcare and policy — when one sector adapts, others follow.

A Shared Responsibility

Inclusion requires families, schools, healthcare providers, policymakers and communities to act together.
