Mental Retardation

Mental retardation is a developmental disability that first appears in children under the age of 18. It is defined as an intellectual functioning level (as measured by standard tests for intelligence quotient) that is well below average and significant limitations in daily living skills (adaptive functioning).

Gene mutations lead to autism and mental retardation
Researchers working with Professor Gudrun Rappold, Director of the Department of Molecular Human Genetics at Heidelberg University Hospital, have discovered previously unknown mutations in autistic and mentally impaired patients in what is known as the SHANK2 gene, a gene that is partially responsible for linking nerve cells. However, a single gene mutation is not always enough to trigger the illness.

Autistic people don't want hugs
Why do people with fragile X syndrome, a genetic defect that is the best-known cause of autism and inherited mental retardation, recoil from hugs and physical touch – even from their parents?

Gene defect can cause sever mental retardation as Angelman syndrome
Researchers at Duke University Medical Center and the University of North Carolina have discovered in mice how a single disrupted gene can cause a form of severe mental retardation known as Angelman syndrome.

Genetic mutation increases risk of preterm birth
Genetic mutations in the Toll-like receptor 4 (TLR4) gene appear to have significant association with inflammatory injury to the placenta and developing baby, researchers from the University of Pittsburgh's department of obstetrics, gynecology and reproductive sciences report at the 28th annual meeting of the Society for Maternal-Fetal Medicine. Scientific sessions continue through Saturday, Feb. 2, at the Dallas Hyatt Regency at Reunion.

Changes in X chromosome may lead to mental retardation
University of Adelaide geneticist Dr Jozef Gecz and a team of Belgium and UK scientists have achieved a major breakthrough in discovering the causes of intellectual disability. Dr Gecz, a senior researcher who is based at the Women's and Children's Hospital in Adelaide, has collaborated with an international research team to reveal that various mutations of a small part of the X chromosome lead to mental retardation.

Fragile X syndrome affecting brain cells
Researchers at UT Southwestern Medical Center are uncovering how brain cells are affected in Fragile X syndrome, the most common cause of inherited mental retardation and the most common genetic cause of autism.

Potential drugs for mental retardation and autism treatment
Researchers at MIT's Picower Institute for Learning and Memory have corrected key symptoms of mental retardation and autism in mice. The work, which will be reported in the Dec. 20 issue of Neuron, indicates that a certain class of drugs could have the same effect in humans. These drugs are not yet approved by the FDA, but will soon be entering into clinical trials.
