Father inspired after child's autism improved by course of antibiotic

---

A parent has been prompted to investigate the connections between gut bacteria and autism following surprising improvements in his son's autism while taking an antibiotic for strep throat.

Amoxicillin is a form of penicillin and is frequently used to treat bacterial infections such as bronchitis, pneumonia and tonsillitis.

John Rodakis' son was prescribed a 10-day course ofamoxicillin, one of the most frequently used  antibiotics in the US, and within just 4 days of commencing the treatment, changes were observed in his autism symptoms.

"[He] began making eye contact, which he had previously avoided; his speech, which was severely delayed, began to improve markedly; he became less 'rigid' in his insistence for sameness and routine; and he also displayed an uncharacteristic level of energy, which he had historically lacked," explains Rodakis.

In an article published in Microbial Ecology in Health and Disease, Rodakis describes this unexpected turn of events and the journey of discovery he has since embarked upon, as he attempts to understand what caused his son's symptoms to change.

It became apparent to him early in his investigation that many other parents had experienced similar changes following courses of antibiotics, with some even routinely giving their autistic children antibiotics in order to improve their symptoms.

As well as these positive experiences, Rodakis also notes that some parents found their children's symptoms worsened under the influence of the medicine. "In my view, these stories are not contradictory but rather reinforce the notion that an antibiotic can create an effect in autism," writes Rodakis..... read more

Link between autism genes and higher intelligence, study suggests

Genes linked with a greater risk of developing autism may also be associated with higher intelligence, a study suggests.

Researchers have found new evidence linking genetic factors associated with autism to better cognitive ability in people who do not have the condition.

The relationship between autism and intelligence is not clear, researchers say. Although up to 70 per cent of individuals with autism have an intellectual disability, some people with the disorder have relatively well-preserved, or even higher than average, non-verbal intelligence, the team says.

Autism is a developmental disability that can cause significant language and speech difficulties. Non-verbal intelligence enables people to solve complex problems using visual and hands-on reasoning skills requiring little or no use of language.

Researchers at the Universities of Edinburgh and Queensland analysed almost 10,000 people recruited from the general population of Scotland. Individuals were tested for general cognitive ability and had their DNA analysed.

The team found that even among people who never develop autism, carrying genetic traits associated with the disorder is, on average, linked to scoring slightly better on cognitive tests...... read more.
