Scientists May Have Found The Root Cause Of Autism | IFLScience

 Scientists think they’ve found out what could be at the root of autism and, no, it’s not vaccines. According to a new study, it could be caused by having too many brain connections called synapses.

“An increased number of synapses creates miscommunication among neurons in the developing brain that correlates with impairments in learning, although we don’t know how,”

    An Infamous Chemical Has Been Strongly Linked To Autism

    The infamous pesticide DDT has been further implicated as a possible trigger for the development of autism spectrum disorder by an international group of epidemiologists and psychiatrists studying children who were exposed in utero.

    The level of DDT in the mother’s system was quantified by a laboratory test for DDE, the chemical that DDT is metabolized into.

    Examining this data revealed that the likelihood of autism was 32 percent higher in children whose mothers harbored DDE levels in the 75th percentile (of the range of concentrations in all subject’s mothers)

    the odds of autism with intellectual disability were a staggering 121 percent higher if the mother had DDE levels above this threshold.

    Both DDT and PCBs affect the actions of male sex hormones in utero – which are being increasingly implicated in autism – yet do so differently. DDT is known to inhibit the production and function of receptors for these hormones, whereas PCBs increase the number of receptors.

    Autism and vaccines: more than half of people in Britain, France, Italy still think there may be a link

    One of the most frustrating misperceptions in our many studies on what people commonly get wrong is the enduring myth that vaccines pose a risk to healthy children. It’s particularly maddening because it has direct and long-lasting consequences.

    In the UK, the rise in cases is often among young adults, who were less likely to be immunised as children during a period of vaccine concern sparked by Andrew Wakefield’s now completely discredited claims that the MMR vaccine caused leaks in the gut that went through the bloodstream to the brain.

    But new doubts keep being layered on, with points about freedom of choice from Italian political parties muddying the waters, and more than 20 tweets from the US president, Donald Trump, suggesting a link. This is despite many reviews that fail to find any link, including a 2014 meta-analysis of records from over 1.25m children.

    Around one in every five people believe that “some vaccines cause autism in healthy children”, and 38% are unsure whether it is true or not.

    Why do we fear vaccines?
    So why do three in five people across these countries feel unsure or believe that there actually is a link between some vaccines and autism in healthy children, despite the claims being so widely discredited? It is partly because it has many of the ingredients that drive conspiracy theories.

    First, it’s a highly emotive issue – there is little more emotional than the health of our children. We treat information differently when we are in highly emotional states

    Second, it involves medical complexity and requires an understanding of risk, which we really struggle with.

    In addition, the communications we do see on vaccines are often actively unhelpful, with sections of the media keeping these stories alive. This does not just mean television shows or articles that give space to those who make the case for the vaccine–autism link without providing space for counter claims.

    Then there is also a more subtle effect from “balanced” reporting. This is where a media item says that while a credible source disagrees with a position, some others still believe it. There is increasing evidence that this apparent balance actually serves to polarise

    In some ways, vaccines are a victim of their own success, because we are much more likely to notice phantom scares than world-changing but incremental improvements. We need to fight these frighteningly widespread vaccine misperceptions to avoid a much more attention-grabbing reverse.

    Scientists May Have Actually Found One Of The Causes Of Autism And Shockingly, It’s Not Vaccines

    Over the past few years, more and more research has been published revealing just how fundamental our gut microbiome is to our health. It can affect everything from our response to fear and negative stimuli, to our weight and mental health, to whether or not we develop autoimmune diseases such as lupus and type 1 diabetes.

    Now, a new study published in The Journal of Immunology has found a link between the gut microbiome and the neurodevelopmental condition autism using animal studies. However, it is not our own microbiome that affects whether or not we develop autism, the researchers say – it’s our mom’s.

    Enabling Autistic Children to Enjoy a Relaxed Visit to the Museum

    The National Museum of Computing in the UK is a great place to learn about the history of computing and decoding machines all the way to modern computers.

    For people with ASD, including Asperger’s syndrome and other mild forms of Autism, environmental influences can be a major problem. This is because a high sensitivity to environmental influences is present in most forms of autism. This sensitivity can seriously impair concentration, even if, as is the case with Asperger’s, those affected show above-average intelligence.

    Despite the burgeoning scientific literature examining the sluggish cognitive tempo (SCT) construct, very little is known about the clinical presentation of SCT. In clinical cases where SCT is suspected, it is critical to carefully assess not only for attention-deficit/hyperactivity disorder (ADHD) but also for other comorbidities that may account for the SCT-related behaviors, especially internalizing symptoms and sleep problems.

    Common Food Additives Have Been Linked To Anxiety And Behavior Changes

    It’s no secret that processed foods are not good for your physical health or your waistline, but a new study has highlighted how a diet rich in particular food additives might even affect your behavior too.

    The additives in question are synthetic emulsifiers – specifically polysorbate 80 and carboxymethylcellulose – that are often added to foods such as cookies, cake, bread, and margarine to improve their texture as well as extend their shelf life.

    16 years ago, a doctor published a study. It was completely made up, and it made us all sicker.
    The entire study was fabricated.

    Once upon a time, a scientist named Dr. Andrew Wakefield published in the medical journal The Lancet that he had discovered a link between autism and vaccines.

    After years of controversy and making parents mistrust vaccines, along with collecting $674,000 from lawyers who would benefit from suing vaccine makers, it was discovered he had made the whole thing up. The Lancet publicly apologized and reported that further investigation led to the discovery that he had fabricated everything.

    In the intervening years, millions have been spent on studying this further to see if there was anything that could connect autism and vaccines.

    “It’s a Spectrum” Doesn’t Mean What You Think

    Everyone knows that autism is a spectrum. People bring it up all the time.

    If only people knew what a spectrum is… because they are talking about autism all wrong.

    People think you can be “a little autistic” or “extremely autistic,” the way a paint colour could be a little red or extremely red.

    But autism isn’t that simple.

    Autism isn’t a set of defined symptoms that collectively worsen as you move “up” the spectrum.

    In fact, one of the distinguishing features of autism is what the DSM-V calls an “uneven profile of abilities.”

    Autistics Make Others Uncomfortable, Instantly

    Autistics make other people uncomfortable, and we do this almost instantly upon meeting. In my communications classes, I teach about the 50 to 500 milliseconds during which most people develop first impressions. These impressions are difficult, nearly impossible, to counteract with evidence and familiarity.

    People With Autism Are Better At Predicting Generalized Social Responses

    Autism spectrum is associated with finding it more difficult to assess the thoughts, emotions, and intentions of others on an individual basis. A Yale University team made the first large-scale test of whether this extends to struggling to predict the behavior of people in groups. To their surprise they found the opposite; people with autism are actually better than the rest of the population at predicting collective responses.

    More Than 100 Identified Genes Found To Be Associated With Autism

    A “landmark study” has identified 102 genes associated with autism spectrum disorder (ASD) in what researchers say may not only lend to understanding the causes and mechanisms behind the condition but may one day pave the way to developing precision treatments for those affected.

    “The take-home message is that there are probably many different paths to autism,” Joseph Buxbaum, Director of the Seaver Autism Center for Research and Treatment at Mount Sinai, told IFLScience. “That is the nature of complex disorders – many of the things that have been studied now and patient-based research is complicated now because the easy stuff has been figured out.”

    “As we look more and more into autism, we are discovering that it is much more complex than we thought,”

    Genes break down into two main classes, the first being a “critically important” component of turning genes “on and off” and the other being involved in nerve function. When mutated, certain genes may alter nerve function, which can be linked to autism.

    Of the 102 genes found to be associated with ASD, 49 are also associated with other developmental delays. Genes associated with ASD and other intellectual disabilities and developmental delays often overlap, but this work begins to tease apart the specificity.
