With increased public awareness of the early signs and recent American Academy of Pediatrics recommendations that all 18- and 24-month-olds be screened for autism spectrum disorders, there is an increasing need for diagnostic assessment of very young children. However, unique challenges exist in applying current diagnostic guidelines for autism spectrum disorders to children under the age of 2 ...
Autism spectrum disorders are a group of developmental disabilities characterized by atypical development in socialization, communication, and behavior. The term autism spectrum disorders describes three of the five pervasive developmental disorders, including autistic disorder, Asperger syndrome, and pervasive developmental disorder—not otherwise specified. Symptoms of autism spectrum disorder...
Chronic infectious diseases, including tick-borne infections such as Borrelia burgdorferi may have direct effects, promote other infections and create a weakened, sensitized and immunologically vulnerable state during fetal development and infancy leading to increased vulnerability for developing autism spectrum disorders. A dysfunctional synergism with other predisposing and contributing facto...
BACKGROUND Aberrant brain connectivity, especially with long-distance underconnectivity, has been recognized as a candidate pathophysiology of autism spectrum disorders. However, a number of diffusion tensor imaging studies investigating people with autism spectrum disorders have yielded inconsistent results. METHODS To test the long-distance underconnectivity hypothesis, we performed a syste...
This study examined the relations among loneliness, friendship, and emotional functioning in adults (N = 108) with autism spectrum disorders. Participants completed self-report measures of symptoms of autism spectrum disorders, loneliness, number and nature of friendships, depression, anxiety, life satisfaction, and self-esteem. The results indicated that loneliness was associated with increase...
Previous work leaves open the question of whether children with autism spectrum disorders aged 6-12 years have delay in producing gestures compared to their typically developing peers. This study examined gestural production among school-aged children in a naturalistic context and how their gestures are semantically related to the accompanying speech. Delay in gestural production was found in c...
AIM To review current studies on the effectiveness of neurofeedback as a method of treatment of the core symptoms of autism spectrum disorders (ASD). METHOD Studies were selected based on searches in PubMed, Ovid MEDLINE, EMBASE, ERIC, and CINAHL using combinations of the following keywords: 'Neurofeedback' OR 'EEG Biofeedback' OR 'Neurotherapy' OR 'Mu-Rhythm' OR 'SMR' AND 'Autism' OR 'Autism...
CONTEXT Mercuric compounds are nephrotoxic and neurotoxic at high doses. Thimerosal, a preservative used widely in vaccine formulations, contains ethylmercury. Thus it has been suggested that childhood vaccination with thimerosal-containing vaccine could be causally related to neurodevelopmental disorders such as autism. OBJECTIVE To determine whether vaccination with a thimerosal-containing ...
normal 0 false false false en-us x-none ar-sa according to the world health organization (who), factors such as growing electricity demand, ever-advancing technologies and changes in social behaviour have led to steadily increasing exposure to man-made electromagnetic fields. dental amalgam fillings are among the major sources of exposure to elemental mercury vapour in the general population....
OBJECTIVE Individuals with autism spectrum disorders typically have normal visuospatial abilities but impaired executive functioning, particularly in abilities related to working memory and attention. The aim of this study was to elucidate the functioning of frontoparietal networks underlying spatial working memory processes during mental rotation in persons with autism spectrum disorders. ME...
