Support Children with Individualized Educational Requirements

Intellectual disability, also known as an intellectual developmental disorder, refers to a condition characterized by limitations in cognitive functioning and adaptive behavior.

Individuals with intellectual disability may experience difficulties in areas such as communication, learning, problem-solving, and daily life skills.


Causes of Intellectual Disability

Intellectual disability can have various causes, including:

  1. Genetic Factors: Some cases of intellectual disability result from genetic conditions, such as Down syndrome, fragile X syndrome, or chromosomal abnormalities.
  2. Prenatal Factors: Certain prenatal factors can contribute to intellectual disability, such as maternal infections, exposure to toxins or drugs, or complications during pregnancy.
  3. Perinatal Factors: Difficulties during childbirth, premature birth, or lack of oxygen to the brain during delivery can also lead to intellectual disability.
  4. Postnatal Factors: Infections, head injuries, malnutrition, exposure to toxins, or neglect during early childhood can impact cognitive development.

Diagnosis of Intellectual Disability

The process of diagnosing intellectual disability involves a comprehensive assessment conducted by medical professionals, psychologists, and specialists in the field. The evaluation typically includes:

  1. Medical Examination: A thorough medical examination helps rule out any underlying medical conditions that may be contributing to intellectual disability.
  2. Intellectual Assessment: Intelligence quotient (IQ) tests are administered to measure cognitive abilities and determine the individual’s intellectual functioning.
  3. Adaptive Behavior Assessment: Evaluating adaptive skills, such as communication, self-care, socialization, and motor skills, helps assess an individual’s ability to function in daily life.
  4. Developmental History: Gather information about the individual’s developmental milestones and any potential factors that may have influenced their cognitive development.
