Autistic people's nerve cells differ before birth, new study finds
"Such studies will lead to a better understanding of brain development in both autistic and typical individuals."
- Autism spectrum disorder (ASD) is a neurodevelopmental condition that can cause significant social, communication, and behavioral challenges.
- Although a diagnosis of autism can typically be made around the age of 2, the average age for diagnosis in the United States is after 4 years old.
- A new study shows that the atypical development of autism in human brain cells starts at the very earliest stages of brain organization, which can happen as early as the third week of pregnancy.

By treating the cells with an array of growth factors, the scientists were able to drive the hair cells to become nerve cells (or neurons), much like those found in either the cortex or the midbrain region.</p><p>These induced pluripotent stem cells (referred to as IPSCs) retain the genetic identity of the person from which they came, and the cells restart their development as it would have happened in the womb. This provides a look into that person's brain development.</p><p>At various stages, the researchers examined the developing cells' appearance and sequenced their RNA to see which genes the cells were expressing. On day 9 of the study, developing neurons from typical people formed "neural rosettes" (an intricate, dandelion-like shape indicative of typically developing neurons). Cells from autistic people formed smaller rosettes (or did not form any rosettes at all), and key developmental genes were expressed at lower levels.</p><p>Days 21 and 35 of the study showed cells from typical and autistic people differed significantly in a number of ways, proving that the makeup of neurons in the cortex differs in the autistic and typically developing brains.</p><p>John Krystal, Ph.D., Editor-in-Chief of Biological Psychiatry, <a href="https://www.sciencedaily.com/releases/2020/08/200824091958.htm" target="_blank">explains</a>: "The emergence of differences associated with autism in these nerve cells shows that these differences arise very early in life."</p><p><strong>Along with the variations, there were some things that proved similar.<br></strong>Additionally, cells directed to develop as midbrain neurons (a brain region that's not implicated in autism dysfunction) showed only negligible differences between typical and autistic individuals. The similarities are just as important as the differences, as they mark how the autistic brain and typical brain develop uniquely from the earliest stages of growth.</p><p>"The use of iPSCs allows us to examine more precisely the differences in cell fates and gene pathways that occur in neural cells from autistic and typical individuals. These findings will hopefully contribute to our understanding of why there is such diversity in brain development," said Dr. Dr. Deepak Srivastava, who supervised the study.</p><p><strong>The intention of this study is not to find ways to "cure" autism, but to better understand the key genetic components that contribute to it.<br></strong>Simon Baron-Cohen, Ph.D., Director of the Autism Research Centre at Cambridge and the study's co-lead, added that "some people may be worried that basic research into differences in the autistic and typical brain prenatally may be intended to 'prevent,' 'eradicate,' or 'cure' autism. This is not our motivation, and we are outspoken in our values in standing up against eugenics and in valuing neurodiversity. Such studies will lead to a better understanding of brain development in both autistic and typical individuals."</p>Hannah Gadsby has a message for anti-vaxxers
In "Douglas," the Australian comedian opens up about her autism diagnosis.
- In her new Netflix special, "Douglas," comedian Hannah Gadsby targets anti-vaxxers.
- Diagnosed with autism four years ago, Gadsby discusses the dangers of believing vaccinations cause autism.
- Some high-profile anti-vax activists use their platform in order to sell supplements and books.

They're also prone to "willfully manipulate statistics," as the osteopathic study proves. This doesn't change the fact that anti-vaxxers are woefully outnumbered, however loud social media seems. Tragically, the loudest voice in the room gets taken seriously, sometimes. </p><p>After discussing her autism diagnosis, Gadsby begins the skit. </p><p style="margin-left: 20px;">"Do you know what causes autism? No, you f***ing don't. If you honestly think you do, your confidence is making you stupid." </p><p>She's aware anti-vaxxers are likely in the room. Her core demographic is wealthy, entitled white women, which is "a Venn diagram with a lot of crossover." Gadsby holds no hope in changing minds, because that's not how closed minds work: "They don't work; they're closed for business." </p><p>She then pretends vaccines cause autism, although "pretending is not science." She's not upset about being on the spectrum. That doesn't mean having autism is easy; quite the contrary. It's difficult to always be the odd one out. That said, Gadsby brilliantly advocates for autism. </p><p style="margin-left: 20px;">"As difficult as this life is, it's nice to have a life. And it's particularly nice to have this life in a world without polio. Polio is bad, and that is a fact, not a feeling."</p><p>Text on a screen will never compare to Gadsby's delivery: the crescendo of "polio," the playful yet serious expression on her face when delivering this information. Her critique doesn't stop there. </p><p style="margin-left: 20px;">"I would rather have autism than be a sociopath like you."</p><p>Tough statement, which she qualifies. Believing your child is more important than all other children means you're not playing for the team. You've wrapped yourself up so tightly in a belief system that self-righteousness has become your creed. Far from being a posture on Twitter, this mindset has real-world consequences. </p><p>First, there's the economic angle. Discredited physician Andrew Wakefield, who was <a href="https://www.bmj.com/content/342/bmj.c5347" target="_blank">paid to falsify data</a> in his infamous measles vaccine-autism study, <a href="http://www.medicine.mcgill.ca/epidemiology/hanley/c609/Material/BMJpartII.pdf" target="_blank">filed a patent</a> for a single-jab measles vaccine as the same time he was decrying vaccines. His objective appears to have been financial from day one. </p>Protesters hold banners against the 5G technology and vaccines as others shout slogans during an anti-government protest in front of the parliament in Sofia on May 14, 2020.

Her book was published by a house whose <a href="https://www.youtube.com/watch?v=j9WuTxRZFNQ&t=74s" target="_blank">sole focus</a> is promoting anti-vaccination rhetoric.</p><p>Second, the health consequences.

The result: over 4,000 children were infected with measles last fall. At least 70 died. An anti-vax advocate <a href="https://www.bbc.com/news/world-asia-50682881" target="_blank">promoted</a> the use of papaya leaf for treating measles; he was later arrested. The situation was so bad, the Samoan government declared a state of emergency and banned children under the age of 17 from gathering publicly. </p><p>Anti-vax rhetoric <a href="https://khn.org/news/why-measles-hits-so-hard-within-n-y-orthodox-jewish-community/" target="_blank">also hit</a> Orthodox Jewish communities hard last year.

More vaccine-autism facts for the fact-averse.
- A massive new study finds absolutely no link between MMR vaccination and autism.
- Some question the expenditure of yet more research money on convincing conspiracy theorists.
- There are already 206 measles cases this year in the U.S., and the disease is up by 30% globally, despite previous near-eradication.
The 2019 Danish vaccine-autism study
<p>The study from scientists at Denmark's Statens Serum Institut finds no statistical link whatsoever between the administration of MMR doses and the likelihood of developing autism. It also found no correlation between areas in which vaccines are administered and clusters of autism diagnoses occur. In fact, as the anti-vax movement has grown, so has the incidence of autism, from 1 out of 68 eight-year-olds having it in 2016, to <a href="http://www.autism-society.org/news/2018-cdc-autism-incidence-rate-statement-from-the-autism-society/" target="_blank" data-vivaldi-spatnav-clickable="1">1 out of 59 in 2018</a>.</p><p>The researchers studied the medical histories of Danish children born between 1999 and the end of 2010. Using population registries, they were able assess other risk factors — including sibling histories of autism — and look for correspondences between vaccinations and the occurrence of autism. Speaking of the statistics presented in the study, global health expert <a href="http://vaccines.emory.edu/faculty-evc/primary-faculty/omer_saad.html" target="_blank" data-vivaldi-spatnav-clickable="1">Saad Omer</a> tells the <a href="https://www.washingtonpost.com/nation/2019/03/05/measles-vaccine-doesnt-cause-autism-says-new-decade-long-study-half-million-people/?utm_term=.b8972078fe24" target="_blank" data-vivaldi-spatnav-clickable="1"><em>Washington Post</em></a>, "The appropriate interpretation is that there's no association whatsoever."</p>Money well spent or wasted?

<p>Dispositive as the new study's evidence is, Omer and others consider it questionable to use research money sorely needed elsewhere to convince anti-vaxxers. As bioethicist <a href="https://sites.google.com/site/sydmjohnson/" target="_blank" data-vivaldi-spatnav-clickable="1">Syd M Johnson</a> says, "They are immune to facts."

By "opportunity cost," Omer refers to the lost chance of developing cures with these funds, warning, "continuing to evaluate the MMR-autism hypothesis might come at the expense of not pursuing some of the more promising leads."</p>A teen leading the way

Why Are So Many Musical Geniuses Asocial? A New Study Reveals an Interesting Link
Musical savants have “enhanced pitch discrimination” and “increased auditory perceptual capacity.” But why?
We often see in the media autistic savants who can write and play music like grand masters with incredible talent and flourish. In fact, of autistic savants and savants in general, having extraordinary musical talent is one of the most common advantages. A new study published in the journal Cognition, suggests a reason for it. Those with autism spectrum disorder (ASD) have superior hearing.
