Which of the following is NOT listed as a health problem causing intellectual disability?

• A. Whooping cough
• B. Meningitis
• C. Lead/mercury exposure
• D. Rubella infection

Answer: (D)

Intellectual disability often results from events or exposures that directly affect brain development or damage brain tissue. Meningitis is an infection that can inflame the brain’s protective layers and cause damage, leading to cognitive impairment. Exposure to heavy metals like lead or mercury disrupts neural development and function, increasing the risk of intellectual disability. If a mother contracts rubella during pregnancy, congenital rubella syndrome can occur, which includes intellectual disability as one of its possible outcomes. Whooping cough, on the other hand, is primarily a respiratory infection and is not typically associated with lasting neurodevelopmental effects like intellectual disability. So the statement that does not belong as a health problem causing intellectual disability is whooping cough.
