Medicalxpress.com: Late-breaking mutations may play an important role in autism

Lim, Walsh and colleagues overlapped the post-zygotic mutations they identified from blood DNA samples with publicly available gene expression data from brain autopsies (via the BrainSpan Project). This enabled them to roughly map the brain regions in which the mutated genes are expressed. In this image, representing prenatal brain

Medicalxpress.com: Study identifies tools to identify patients at risk for autism spectrum disorders

A tool intended to detect signs of autism in high-risk infants can be used to help identify and treat patients with tuberous sclerosis complex (TSC), a genetic disorder, who most need early intervention. Moreover, they can identify these patients earlier than ever before.

A new study, published online in

Avoiding direct eye contact with others is one of the most common characteristics associated with individuals with Autism Spectrum Disorder. Many non-spectrum folks have traditionally assumed it is a sign of social or personal indifference.

Not so, says a new study published this month in

There is greater variety in the size of men’s brains than of women’s. This could help explain why some psychiatric disorders such as ADHD and autism are more prevalent in boys. Leiden brain researcher Lara Wierenga has published an article about this in the international journal

Individuals with autism spectrum disorder (ASD) often find it difficult to look others in the eyes. This avoidance has typically been interpreted as a sign of social and personal indifference, but reports from people with autism suggests otherwise. Many say that looking others in the eye is uncomfortable or stressful for them – some will even say that “it burns” – all of which points to a neurological cause. Now,
