Intellectual Disability (ID

Intellectual Disability (ID) is a condition characterized by limitations in intellectual functioning and adaptive behavior, which covers many everyday social and practical skills. This condition begins before the age of 18.

🔹 Key Features of Intellectual Disability:

1. Below-average intellectual functioning:

   • Typically measured by an IQ score below 70.
   • Difficulty in reasoning, problem-solving, planning, abstract thinking, judgment, and academic learning.

2. Deficits in adaptive functioning:

   • Challenges in daily life skills, including:
     • Conceptual skills: language, reading, writing, money, time, number concepts.
     • Social skills: interpersonal skills, social responsibility, self-esteem, gullibility, social problem-solving.
     • Practical skills: personal care, job responsibilities, money management, recreation, and use of community resources.

3. Onset during the developmental period:

   • Signs usually appear during childhood or adolescence.
   • It is not something acquired in adulthood through brain injury or disease.

🔹 Levels of Intellectual Disability:

ID can be classified into levels depending on severity:

Level	IQ Range (approx.)	Description
Mild	50–70	Can live independently with support; struggles academically
Moderate	35–49	Needs daily support; limited communication skills
Severe	20–34	Requires extensive support; very limited language
Profound	Below 20	Dependent for all care; very limited understanding

🔹 Causes of Intellectual Disability:

• Genetic conditions (e.g., Down syndrome, Fragile X syndrome)
• Problems during pregnancy (e.g., malnutrition, infections, substance abuse)
• Birth complications (e.g., oxygen deprivation)
• Childhood illnesses or injuries (e.g., meningitis, brain injury)
• Environmental factors (e.g., lead exposure, extreme poverty)

🔹 Diagnosis:

• Standardized IQ testing
• Assessment of adaptive functioning
• Developmental history and clinical evaluation

🔹 Support and Intervention:

While ID cannot be cured, early intervention, special education, therapy, and community-based support can greatly improve quality of life. The focus is on helping the person achieve maximum independence and inclusion in society.
