Close monitoring could give early warning of MS disease course

Patients with multiple sclerosis who have breakthrough disease activity early in the course of treatment with interferon beta-1a are at high risk for severe worsening and poor long-term outcomes, research shows.

Adults with autism have unreliable neural sensory responses to visual, auditory and touch

Autistic adults have unreliable neural sensory responses to visual, auditory, and touch stimuli, according to research published in the journal Neuron. This poor response reliability, the study's authors conclude, appears to be a fundamental neural characteristic of autism.

Obese adults with excess visceral fat, biomarkers of insulin resistance more likely to develop diabetes

Obese adults with excess visceral fat (fat located inside the abdominal cavity, around the body's internal organs) and biomarkers of insulin resistance had an associated increased risk for the development of type 2 diabetes mellitus, while obese individuals with higher amounts of total body fat and subcutaneous fat (underneath the skin) did not have this increased risk, according to a study in the September 19 issue of JAMA, and theme issue on obesity.

Obese individuals with excess visceral fat more likely to develop type 2 diabetes

Obese individuals with excess visceral fat (abdominal fat that surrounds the body-s internal organs) have an increased risk for the development of Type 2 diabetes, according to a new study by researchers at UT Southwestern Medical Center. By contrast, persons with excess abdominal subcutaneous fat (fat underneath the skin) were not at higher risk for the onset of diabetes.

‘C’ variant disrupts brain connectivity in children with ASD

Over the past decade, researchers have made great strides in identifying genes that lead to an increased risk of autism spectrum disorders (ASD), which result in a continuum of social deficits, communication difficulties and cognitive delays. But it's still critical to determine how exactly these genetic risk factors impact the brain's structure and function so that better treatments and interventions can be developed.
