Biomarkers identified in ASD children
Tuesday, 05 October 2010

Researchers at Imperial College London analysed urine samples from children with ASD, non-autistic siblings and age-matched 'controls' and found increased levels of certain gut bacterial metabolites in the ASD group.  These results suggest that these metabolites could exert some kind of clinical effect in autistic individuals.

Differences in gut micro flora have been suggested as part of the problem with previous studies reporting high levels of Clostridia spp in children with autism.

Oxytocin may improve social behaviour in ASD
Friday, 13 August 2010

Oxytocin is the hormone involved in labour and lactation ( breastfeeding).  It plays a crucial role in the bonding process bewteen mother and baby and as such is thought to have a role in social and emotional behaviour.  Levels of this hormone have been found to be reduced in autistic subjects.

A team of reserachers at the Centre de Neuroscience Cognitive in France, took a group of individuals with high-functioning autism or Asperger syndrome and measured their social behaviour ( ball tossing game and looking at photos of faces ) before and after taking oxytocin via inhalation.  They found that patients responded more strongly to others and exhibited more approriate social behaviour after receiving the oxytocin, suggesting a possible therapeutic strategy.

Mitochondrial Dysfunction in ASD
Friday, 13 August 2010

Researchers have found more evidence that there is some kind of problem with mitochondria ( the power plants of cells ) in individuals with autism.  Plasma samples of children with autism, non-autistic siblings and controls ( no family history of ASD) were analysed and found to show' universal and unambiguous alterations in lipid metabolism' as well as reduced levels of glutathione, methionine and cysteine.

Lab tests on normal liver, neuronal and astrocyte ( cells that attach neurones to blood vessels ) cells showed that when exposed to high levels of glutamate ( a biochemical that excites nerve cells ) there was a decrease in levels of glutathione, methionine and cysteine similar to the abnormalities seen with the autistic subjects.

Conference on Diet & ASD-Parents Welcome
Monday, 14 June 2010

The newly launched ESPA ( Eduaction and Services for People with Autism ) is running a conference on 'Diet Intervention in Autism Spectrum Conditions' on Wednesday 6th October in Sunderland and parents are welcome to attend.

 

Experts on dietary interventions, including my colleague from the Dietitians in Autism 'group' David Rex, will be speaking and it promises to be a particularly useful event.
