Annotation: tuberous sclerosis

Article Abstract:

There are many unresolved issues surrounding the rare genetic disorder of tuberous sclerosis, including its natural history and medical management, but it is possible to give some guidelines on these issues. The condition has physical manifestations, including typical skin lesions and cortical tubers and subependymal nodules in the brain. It has neuropsychiatric manifestations, including epilepsy. There are cognitive and developmental impairments, and 51% of sufferers are autistic. Hyperactivity is common. Researchers have found some evidence for a link between specific brain abnormalities and other manifestations.

A model of preverbal social development and its application to social dysfunctions in autism

Article Abstract:

Studies of early face perception are used to develop a model of how face expressions might be transduced to initiate consonant internal affect, related outward expressions and other behaviors. Underlying neural mechanisms and processes are identified, and the model is generalized to offer an account of aspects of typical preverbal social development, which is then used to develop aetiological hypotheses about the lack of social interest and motivation in autism, and to provide a framework for evaluating other theories of autism.

Speech-in-noise perception in high-functioning individuals with autism or Asperger's syndrome

Article Abstract:

Speech-in-noise perception abilities in high-functioning individuals with autism or Asperger's syndrome were measured using speech reception thresholds (SRTs). The study revealed that a reduction in the ability to gather information through glimpses present in the temporal dips in the noise generated this syndrome or deficit.
