Current intellectual deficits of two or more standard deviations below the population mean, which generally translates into performance in the lowest 3% of a person's age and cultural group, or an IQ of 70 or below.

In addition, this study examined guidelines for consideration of intelligence test part scores and consideration of the unreliability of IQs through consideration of the standard error of measurement (SEM) or an IQ range. As found in previous studies, results revealed great variation in the specific eligibility guidelines for MR from state to state. The greatest variation appeared to be across the adaptive behavior considerations. Approximately 20% of states (10) recommend consideration of intelligence test part scores, and approximately 39% of states (20) recommend attention to unreliability of IQs through consideration of the SEM...

Questions are raised, based on analysis of data from a sample of 200 young adults, regarding the use of different composite scores from intelligence batteries in place of the total (full scale) IQ score when considerable variability exists in an IQ batteries composite scores.

As noted in Science Daily, the study links a “large family of genes known as protocadherins with a condition known as ‘epilepsy and mental retardation limited to females’ (EFMR).” EFMR is described as “relatively uncommon” and also hereditary, …….with successive generations of women affected. In just one of seven families studied across the world, 23 women were affected by the disorder across five generations. This discovery will now enable such families to benefit from genetic counselling, including screening for the genetic muta...

Antipsychotics are generally not FDA-approved for the treatment of aggressive behavior, this has simply been an off-label and common practice by many physicians for years. The researchers followed 86 non-psychotic people with an intellectual disability (what we in the U.S. would term either a developmental disability or mental retardation) and aggressive or challenging behaviors. Patients were randomly assigned to one of three treatment groups — an older antipsychotic (Haldol), a newer at...
