Efforts to ease the symptoms of autism are beginning to ramp up, with promising candidates in various stages of testing.
Attention deficit hyperactivity disorder (ADHD) and autism may have more in common than childhood onset and a few similar symptoms. New research suggests the conditions share genetic roots.
Toddlers with autism pay less attention to faces than do healthy controls, but both groups give equal attention to objects, according to a study published in the Archives of General Psychiatry. The findings challenge the idea that individuals with autism have a generalized problem with attention, suggesting instead that they struggle with attending specifically to social stimuli, researchers say.
At 6 months of age, babies who will later develop autism begin to lose some of their social skills and continue to regress until age 3, according to a study published in the Journal of the American Academy of Child & Adolescent Psychiatry.
Researchers have found a higher density of several types of interneurons — nerve cells that connect sensory and motor neurons in the brain— in postmortem brain tissue from individuals with autism, compared with healthy controls. The findings appear in the February issue of Acta Neurologica Scandinavica.
