There are three criteria for mental retardation. 1) IQ must be below approximately 70, as measured by an intelligence test, or in roughly the bottom 2% of the population. 2) This decline in IQ must interfere with the person's ability to function in daily life. For example, a person with mild mental retardation may have difficulty handling money, cooking for themselves, or taking medicine as prescribed. 3) Onset of these difficulties must occur prior to age 18. This is why, when a person develops these problems as a result of Alzheimer's Disease or other dementia, they are not described as mentally retarded.
