An intellectual disability affects how a person thinks, learns, and processes information. It can make understanding, communicating, socialising, and managing emotions more challenging. Intellectual disabilities can be classified as mild, moderate, or severe, depending on the level of independence or reliance on others.

Causes of Intellectual Disability

There are many different causes of intellectual disability, which may be present from birth or develop before the age of 18. Some common causes include:

• Genetic disorders, such as:
  • Down Syndrome
  • Fragile X Syndrome
  • Williams Syndrome
  • Prader-Willi Syndrome
• Childhood illnesses, such as:
  • Meningitis
  • Whooping cough or measles
• Birth trauma, which may involve a lack of oxygen to the brain, sometimes linked with conditions like cerebral palsy.

Other contributing factors can include exposure to toxins, brain malformation, maternal disease, or environmental influences such as prenatal exposure to alcohol or drugs.

Early Signs of Intellectual Disability

Intellectual disability in children is often detected when they are delayed in reaching developmental milestones. These are age-specific skills in areas such as playing, learning, speaking, and moving.

Signs may include:

• Delays in sitting up, crawling, or walking
• Difficulty with speech and memory
• Challenges with social interaction
• Problems with problem-solving and understanding consequences

Impact on Adolescents and Adults

As individuals grow, they typically develop adaptive functioning skills, which help them manage daily life and interact with others. Intellectual disabilities can impact how these skills are developed compared to peers. These skills are generally divided into three areas:

• Conceptual: Skills like language, reading, writing, and memory.
• Social: Understanding empathy, communication, social norms, and developing relationships.
• Practical: Independence in personal care, managing work, school, and financial responsibilities.

Additionally, intellectual disabilities can affect intellectual functioning, which includes learning new skills and performing well at school or work.

Early Intervention for Children with Intellectual Disabilities

Research shows that early intervention can significantly benefit children with intellectual disabilities by enhancing their development. Early intervention is typically provided by professionals such as:

• Occupational Therapists
• Speech Pathologists
• Psychologists
• Social Workers

Other early childhood support professionals funded by the NDIS may include developmental educators, early childhood teachers, and therapy assistants.

Can Therapy Help Teens and Adults with Intellectual Disabilities?

Yes! Capacity-building therapies provided by qualified professionals can be highly beneficial across all ages. These therapies help individuals develop daily living skills and strategies to make tasks easier.

Therapists begin with an assessment to tailor the intervention to the person’s unique needs. This assessment may take multiple sessions and often results in a report with recommendations for ongoing support.
