Neural correlates of self-injurious behavior in Prader-Willi syndrome

Neural correlates of self-injurious behavior in Prader-Willi syndrome.

Individuals with Prader-Willi syndrome (PWS), a genetic disorder caused by mutations to the q11-13 region on chromosome 15, commonly show severe skin-picking behaviors that can cause open wounds and sores on the body. To our knowledge, however, no studies have examined the potential neural mechanisms underlying these behaviors. Seventeen individuals with PWS, aged 6-25 years, who showed severe ...

Self-injurious behavior: A comparison between Prader-Willi syndrome, Down syndrome and Autism

The term Self-injurious Behavior (SIB) represents behavioral characteristics that can damage body tissue. Persons with Intellectual Disability (ID) have a greater probability of developing inadequate behavior such as SIB. Literature indicates the presence of SIB in different syndromes. In the Prader-Willi Syndrome (PWS) the most frequent physical manifestation is skin-picking, which involves th...

Prader-Willi Syndrome

Prader-Willi syndrome is a neurogenetic disorder characterized by hypotonia and feeding difficulties in infancy, followed by hyperphagia, hypogonadism, mental retardation, and short stature. It was the first recognized microdeletion syndrome identified with high-resolution chromosome analysis, the first recognized human genomic imprinting disorder, and the first recognized disorder resulting fr...

Prader-Willi syndrome.

Prader-Willi syndrome is a multi system disorder characterized by neonatal hypotonia, later obesity, hyperphagia and mental retardation. It occurs sporadically, either as a result of microdeletion of chromosome 15p (70%) or as a result of maternal disomy of chromosome 15 (30%). The major problems encountered by parents are those of hyperphagia, food-seeking and obesity, and conduct disorder, pa...
