Cognition and behavior: Regression marks autism syndrome

by  /  12 September 2012

Characteristic symptoms of Phelan-McDermid syndrome — a disorder caused by the loss of the 22q13.3 chromosomal region — may include bipolar disorder and a sudden loss of skills during adulthood, according a study published in June in Molecular Syndromology.

Genetics: Rare epilepsy syndromes share autism mutations

by  /  22 August 2012

Individuals with either of two rare forms of epilepsy have duplications or deletions that encompass genes implicated in autism and language impairment, according to a study published 27 June in Epilepsia.

Scientists track adult regression in autism-related syndrome

by  /  26 July 2012

Several scientists at the Phelan-McDermid Syndrome Foundation’s annual meeting focused on the wide range of symptoms, including a sudden loss of motor and cognitive skills, that seem to crop up in adults with the disorder.


Historic diagnosis

by  /  13 July 2012

Childhood disintegrative disorder may be the longest-lived of childhood psychiatric diagnoses. Austrian educator Theodor Heller described it more than 100 years ago, while working in a school for disabled children he had founded with his father. That reign may soon come to an end.


Maternal antibodies may affect brain size in autism

by  /  12 July 2012

The action of certain maternal antibodies on the fetal brain may underlie the large brain size seen in some children with autism, according to preliminary findings from both monkey and human studies presented at a conference in Boston last week.

Facial features provide clue to autism severity

by  /  20 October 2011

Boys with autism have a distinct facial structure that differs from that of typically developing controls, according to a study published 14 October in Molecular Autism.


Molecular mechanisms: Pathway linked to regressive autism

by  /  12 October 2011

Defects in a signaling pathway that regulates learning and memory could underlie regressive autism, a sudden loss of language or social ability.
