💛 Intellectual Disability (Intellectual Developmental Disorder – DSM-5-TR) Easy Read Guide – Students, Parents, Carers, Educators

 



1️⃣ What is Intellectual Disability?

  • Intellectual disability is a condition that starts in childhood.

  • It affects:

    • Learning and understanding information

    • Communication and social skills

    • Daily life skills, like self-care and work

  • Not laziness – it is a developmental condition

  • With support, people can live full and meaningful lives


2️⃣ How is it Diagnosed?

Doctors use a guide called DSM-5-TR.

To be diagnosed, a person must have all three:

  1. Difficulties with thinking and learning

    • Understanding information

    • Solving problems

    • Learning at school or in daily life

    • Remembering things

    • IQ may be tested (~65–75), but IQ alone is not enough

  2. Difficulties with daily life skills
    These are called adaptive skills, grouped as:

    • Conceptual: reading, writing, numbers, money, time

    • Social: talking to others, understanding feelings, making friends

    • Practical: personal care, daily routines, work or school tasks

  3. Start before age 18

    • Problems must begin in childhood or teenage years


3️⃣ Levels of Support

  • Mild: some support needed

  • Moderate: regular support needed

  • Severe: a lot of support needed

  • Profound: full-time support needed

Support can include:

  • Individualised education plans (IEPs in US / EHCPs in UK)

  • Therapy and life skills training

  • Family, community, and school support


4️⃣ Symptoms of Intellectual Disability

A. Intelligence-related symptoms

  • Slow or delayed learning in school or daily life

  • Slower reading and comprehension

  • Difficulty with reasoning, judgment, problem-solving, and planning

  • Distractibility or trouble focusing

B. Adaptive behavior symptoms

  • Slower learning of self-care (bathing, dressing, toilet training)

  • Slower social development and understanding social rules

  • Needing help with daily activities longer than expected

  • Difficulty managing time, money, chores, appointments, or medications

  • Trouble understanding social boundaries

  • Difficulty forming friendships or romantic relationships


5️⃣ Causes of Intellectual Disability

Before birth (prenatal):

  • Genetics: inherited conditions like Down syndrome, Fragile X, Prader-Willi

  • Infections: rubella, toxoplasmosis affecting fetal brain

  • Teratogens: alcohol, tobacco, certain medications, radiation

  • Medical conditions in pregnancy: thyroid problems or hormonal issues

During birth:

  • Lack of oxygen (hypoxia)

  • Premature birth

  • Brain injuries during delivery

Early childhood:

  • Brain injuries or accidents

  • Exposure to toxins like lead or mercury

  • Infections like meningitis or measles

  • Tumors or growths in the brain

  • Medical conditions like epilepsy or severe seizures


6️⃣ Conditions that Can Occur Alongside Intellectual Disability

  • ADHD (Attention Deficit / Hyperactivity Disorder)

  • Autism Spectrum Disorder

  • Impulse control disorders

  • Anxiety or depression

  • Movement disorders

  • Health problems linked to specific genetic conditions


7️⃣ Diagnosis & Tests

  • Multiple steps: assessing intelligence and adaptive skills

  • Early identification: some tests can identify ID in young children

  • Severity classification:

    • Mild: mental age 9–12, may work/live independently with support (~85% of cases)

    • Moderate: mental age 6–9, can communicate simply, needs varying support

    • Severe: mental age 3–6, communicates with words/gestures, daily care needed

    • Profound: mental age <3, usually nonverbal, full-time care needed

Possible tests:

  • IQ and adaptive functioning assessments

  • Laboratory tests (blood, urine)

  • Genetic counseling

  • Brain imaging (MRI, CT scans)


8️⃣ Management & Treatment

No cure exists, but support improves quality of life.

Treatment includes:

  • Education support: IEPs, modified learning programs

  • Behavioral support: learning daily skills and adaptive behaviors

  • Vocational training: work-related skills and independence

  • Family education: helping caregivers support a loved one

  • Medication: for related conditions (anxiety, ADHD, seizures, etc.)


9️⃣ Important Message

  • Intellectual disability is developmental, not caused by laziness

  • IQ alone does not define a person

  • Support is tailored to daily life skills

  • With the right support, people can live meaningful, independent lives
