Intellectual disabilities (ID) are a broad category of neurodevelopmental disorders that affect the cognitive and adaptive functioning of the affected person.
Formerly, intellectual disabilities were generally termed “mental retardation.” However, on the 5th of October, 2010, President Barack Obama signed the legislation that officially changed these terms.
Intellectual disabilities, which often emerge in the developmental stages of life, pose challenges in the different areas of the person’s life. These areas include learning, reasoning, problem-solving, and adapting to basic daily activities.
Some types of intellectual disabilities are Down syndrome, Fragile X syndrome, Phenylketonuria (PKU), Fetal Alcohol Spectrum Disorders, and Prader-Willi Syndrome.
Having defined what an intellectual disability truly is, let us now discuss the root causes and some diagnostic processes. We will also consider possible measures to help affected individuals and their families manage their conditions.
WHAT CAUSES INTELLECTUAL DISABILITIES?
Like most disabilities, intellectual disabilities can sprout from different causes. The major influencing factor for this variation is that intellectual disabilities can happen at any age, from birth to 18.
- Genetics: Gene mutations passed down from parents or those that occur during fetal development lead to intellectual disabilities. Some intellectual disabilities that happen because of genetics are Down syndrome and Fetal X syndrome.
- Prenatal and Birth Complications: A pregnant woman’s diet and health go a long way in determining the child’s health, growth, and development. Intake of drugs and alcohol, improperly treated maternal infections, and complications during childbirth leading to asphyxia can affect the baby’s brain and cause intellectual disabilities.
- Environmental Exposures: Conditions like meningitis, measles, whooping cough, and exposure to toxins like mercury and lead can contribute to these disabilities.
- Malnutrition: Children require all essential nutrients from birth and throughout the developmental ages for optimum brain development. When these nutrients are absent in the child’s diet, there is a risk of developing intellectual disabilities.
- Traumatic Brain Injury: Some head injuries and accidents can cause developmental disabilities, especially during developmental stages.
DIAGNOSIS
Detecting intellectual disabilities involves a series of comprehensive evaluations and observations over the developmental ages rather than relying on a one-time test. These evaluations begin with a medical evaluation that analyses the child’s prenatal and birth history, moving on to genetic tests to pinpoint genetic conditions like Down syndrome.
Health professionals also closely monitor developmental milestones to ensure the child progresses like children in that age bracket because significant delays are clear signs of intellectual disabilities.
Another vital diagnostic test is the IQ test, which assesses cognitive capabilities and the ability to handle adaptive behavior challenges compared to how other members of their peer group handle the same challenges. A score below 70 indicates an intellectual disability.
THE WAY FORWARD
Understanding and recognizing intellectual disabilities is the first step toward a breakthrough. Early intervention plays a vital role in this breakthrough because these programs provide therapy and skill-building at a young age, significantly improving development.
Also, specific education strategies enable affected persons to learn at their own pace. As the children develop, the focus can shift to vocational training to prepare the children for jobs, promoting self-sufficiency.
The community should include affected people in community activities to reduce social stigma and promote social interactions. Families can also form support groups so caregivers and affected individuals can connect and share experiences throughout their journey.
A LIFELONG JOURNEY
Intellectual disabilities are a lifelong journey, but they do not define the individual or their potential. With early diagnosis, appropriate support, and societal understanding, individuals with intellectual disabilities can lead fulfilling lives and make meaningful contributions to their communities.
Over the next couple of weeks, we will look at specific intellectual disabilities, providing more insights and understanding. The Awareness Journey continues.
