What’s the difference between autism and Asperger’s disorder?

Swedish climate activist Greta Thunberg describes herself as having Asperger’s while others on the autism spectrum, such as Australian comedian Hannah Gatsby, describe themselves as “autistic”. But what’s the difference?
Today, the previous diagnoses of “Asperger’s disorder” and “autistic disorder” both fall within the diagnosis of autism spectrum disorder, or ASD.
Autism describes a “neurotype” – a person’s thinking and information-processing style. Autism is one of the forms of diversity in human thinking, which comes with strengths and challenges.
When these challenges become overwhelming and impact how a person learns, plays, works or socialises, a diagnosis of autism spectrum disorder is made.
Where do the definitions come from?
The Diagnostic and Statistical Manual of Mental Disorders (DSM) outlines the criteria clinicians use to diagnose mental illnesses and behavioural disorders.
Between 1994 and 2013, autistic disorder and Asperger’s disorder were the two primary diagnoses related to autism in the fourth edition of the manual, the DSM-4.
In 2013, the DSM-5 collapsed both diagnoses into one autism spectrum disorder.
How did we used to think about autism?
The two thinkers behind the DSM-4 diagnostic categories were Baltimore psychiatrist Leo Kanner and Viennese paediatrician Hans Asperger. They described the challenges faced by people who were later diagnosed with autistic disorder and Asperger’s disorder.
Kanner and Asperger observed patterns of behaviour that differed to typical thinkers in the domains of communication, social interaction and flexibility of behaviour and thinking. The variance was associated with challenges in adaptation and distress.

Between the 1940s and 1994, the majority of those diagnosed with autism also had an intellectual disability. Clinicians became focused on the accompanying intellectual disability as a necessary part of autism.
The introduction of Asperger’s disorder shifted this focus and acknowledged the diversity in autism. In the DSM-4 it superficially looked like autistic disorder and Asperger’s disorder were different things, with the Asperger’s criteria stating there could be no intellectual disability or delay in the development of speech.
Today, as a legacy of the recognition of the autism itself, the majority of people diagnosed with autism spectrum disorder – the new term from the DSM-5 – don’t a have an accompanying intellectual disability.
What changed with ‘autism spectrum disorder’?
The move to autism spectrum disorder brought the previously diagnosed autistic disorder and Asperger’s disorder under the one new diagnostic umbrella term.
It made clear that other diagnostic groups – such as intellectual disability – can co-exist with autism, but are separate things.
The other major change was acknowledging communication and social skills are intimately linked and not separable. Rather than separating “impaired communication” and “impaired social skills”, the diagnostic criteria changed to “impaired social communication”.
The introduction of the spectrum in the diagnostic term further clarified that people have varied capabilities in the flexibility of their thinking, behaviour and social communication – and this can change in response to the context the person is in.
Why do some people prefer the old terminology?
Some people feel the clinical label of Asperger’s allowed a much more refined understanding of autism. This included recognising the achievements and great societal contributions of people with known or presumed autism.
The contraction “Aspie” played an enormous part in the shift to positive identity formation. In the time up to the release of the DSM-5, Tony Attwood and Carol Gray, two well known thinkers in the area of autism, highlighted the strengths associated with “being Aspie” as something to be proud of. But they also raised awareness of the challenges.
What about identity-based language?
A more recent shift in language has been the reclamation of what was once viewed as a slur – “autistic”. This was a shift from person-first language to identity-based language, from “person with autism spectrum disorder” to “autistic”.
The neurodiversity rights movement describes its aim to push back against a breach of human rights resulting from the wish to cure, or fundamentally change, people with autism.

The movement uses a “social model of disability”. This views disability as arising from societies’ response to individuals and the failure to adjust to enable full participation. The inherent challenges in autism are seen as only a problem if not accommodated through reasonable adjustments.
However the social model contrasts itself against a very outdated medical or clinical model.
Current clinical thinking and practice focuses on targeted supports to reduce distress, promote thriving and enable optimum individual participation in school, work, community and social activities. It doesn’t aim to cure or fundamentally change people with autism.
A diagnosis of autism spectrum disorder signals there are challenges beyond what will be solved by adjustments alone; individual supports are also needed. So it’s important to combine the best of the social model and contemporary clinical model.

The Worry Trick – by Dr. David Carbonell

Worry is a time-sink that rarely does us any good, and often does us harm. Many books have been written on how to fight anxiety… That’s not what this book’s about.
Dr. David Carbonell, in contrast, encourages the reader to stop trying to avoid/resist anxiety, and instead, lean into it in a way that detoothes it.
He offers various ways of doing this, from scheduling time to worry, to substituting “what if…” with “let’s pretend…”, and guides the reader through exercises to bring about a sort of worry-desensitization.
The style throughout is very much pop-psychology and is very readable.
If the book has a weak point, it’s that it tends to focus on worrying less about unlikely outcomes, rather than tackling worry that occurs relating to outcomes that are likely, or even known in advance. However, some of the techniques will work for such also! That’s when Dr. Carbonell draws from Acceptance and Commitment Therapy (ACT).
Bottom line: if you would like to lose less time and energy to worrying, then this is a fine book for you.

What’s Lurking In Your Household Air?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
As individuals, we can’t do much about the outside air. We can try to spend more time in green spaces* and away from traffic, and we can wear face-masks—as was popular in Tokyo and other such large cities long before the pandemic struck.
*The well-known mental health benefits aside (and contrary to British politician Amber Rudd’s famous assertion in a televised political debate that “clean air doesn’t grow on trees”), clean air comes mostly from trees—their natural process of respiration scrubs not only carbon dioxide, but also pollutants, from the air before releasing oxygen without the pollutants. Neat!

We are fortunate to be living in a world where most of us in industrialized countries can exercise a great degree of control over our home’s climate. But, what to do with all that power?
Temperature
Let’s start with the basics. Outside temperature may vary, but you probably have heating and air conditioning. There’s a simple answer here; the optimal temperature for human comfort and wellbeing is 20℃ / 68℉:
Scientists Identify a Universal Optimal Temperature For Life on Earth
Note: this does not mean that that is the ideal global average temperature, because that would mean the polar caps are completely gone, the methane stored there released, many large cities underwater, currently hot places will be too hot for human life (e.g. outside temperatures above human body temperature), there will be mass extinctions of many kinds of animals and plants, including those we humans require for survival, and a great proliferation of many bugs that will kill us. Basically we need diversity for the planet to survive, arctic through to tropical and yes, even deserts (deserts are important carbon sinks!). The ideal global average temperature is about 14℃ (we currently have about 15℃ and rising).
But, for setting the thermostat in your home, 20℃ / 68℉ is perfect for most people, though down as far as 17℃ / 61℉ is fine too, provided other things such as humidity are in order. In fact, for sleeping, 18℃ / 62℉ is ideal. This is because the cooler temperature is one of the several things that tell our brain it is nighttime now, and thus trigger secretion of melatonin.
If you’re wondering about temperatures and respiratory viruses, by the way, check out:
The Cold Truth About Respiratory Infections: The Pathogens That Came In From The Cold
Humidity
Most people pay more attention to the temperature in their home than the humidity, and the latter is just as important:
❝Conditions that fall outside of the optimal range of 40–60% can have significant impacts on health, including facilitating infectious transmission and exacerbating respiratory diseases.
When humidity is too low, it can cause dryness and irritation of the respiratory tract and skin, making individuals more susceptible to infections.
When humidity is too high, it can create a damp environment that encourages the growth of harmful microorganisms like mould, bacteria, and viruses.❞
~ Dr. Gabriella Guarnieri et al.
So, if your average indoor humidity falls outside of that range, consider getting a humidifier or dehumidifier, to correct it. Example items on Amazon, for your convenience:
Humidity monitor | Humidifier | Dehumidifier
See also, about a seriously underestimated killer:
Pneumonia: Prevention Is Better Than Cure
Now, one last component to deal with, for perfect indoor air:
Pollution
We tend to think of pollution as an outdoors thing, and indeed, the pollution in your home will (hopefully!) be lower than that of a busy traffic intersection. However…
- The air you have inside comes from outside, and that matters if you’re in an urban area
- Even in suburban and rural areas, general atmospheric pollutants will reach you, and if you’ve ever been subject to wildfire smoke, you’ll know that’s no fun either.
- Gas appliances in the home cause indoor pollution, even when carbon monoxide is within levels considered acceptable. This polluting effect is much stronger for open gas flames (such as on gas cookers/stoves, or gas fires), than for closed gas heating systems (such as a gas-powered boiler for central heating).
- Wood stoves/fireplaces are not an improvement, in fact they are worse, and don’t get us started on coal. You should not be breathing these things, and definitely should not be burning them in an enclosed space.
- That air conditioning, humidifier, dehumidifier? They may be great for temperature and humidity, but please clean/change the filter more often than you think is necessary, or things will grow there and then your device will be adding pathogens to the air as it goes.
- Plug-in air-freshening devices? They may smell clean, but they are effectively spraying cleaning fluids into your lungs. So please don’t.
So, what of air purifiers? They can definitely be of benefit. for example:
But watch out! Because if you don’t clean/change the filter regularly, guess what happens! That’s right, it’ll be colonized with bacteria/fungus and then be blowing those at you.
And no, not all of them will be visible to the naked eye:
Is Unnoticed Environmental Mold Harming Your Health?
Taking a holistic approach
The air is a very important factor for the health of your lungs (and thus, for the health of everything that’s fed oxygen by your lungs), but there are more things we can do as well:

A Therapeutic Journey – by Alain de Botton
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
We’ve often featured The School of Life’s videos here on 10almonds, and most of those are written by (and often voiced by) Alain de Botton.
This book lays out the case for mental health being also just health, that no person is perfectly healthy all the time, and sometimes we all need a little help. While he does suggest seeking help from reliable outside sources, he also tells a lot about how we can improve things for ourselves along the way, whether by what we can control in our environment, or just what’s between our ears.
In the category of limitations, the book is written with the assumption that you are in a position to have access to a therapist of your choice, and in a sufficiently safe and stable life situation that there is a limit to how bad things can get.
The style is… Alain de Botton’s usual style. Well-written, clear, decisive, instructive, compassionate, insightful, thought-provoking.
Bottom line: this isn’t a book for absolutely everyone, but if your problems are moderate and your resources are comfortable, then this book has a lot of insights that can make your life more easy-going and joyful, without dropping the seriousness when appropriate.

How does cancer spread to other parts of the body?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
All cancers begin in a single organ or tissue, such as the lungs or skin. When these cancers are confined in their original organ or tissue, they are generally more treatable.
But a cancer that spreads is much more dangerous, as the organs it spreads to may be vital organs. A skin cancer, for example, might spread to the brain.
This new growth makes the cancer much more challenging to treat, as it can be difficult to find all the new tumours. If a cancer can invade different organs or tissues, it can quickly become lethal.
When cancer spreads in this way, it’s called metastasis. Metastasis is responsible for the majority (67%) of cancer deaths.
Cells are supposed to stick to surrounding tissue
Our bodies are made up of trillions of tiny cells. To keep us healthy, our bodies are constantly replacing old or damaged cells.
Each cell has a specific job and a set of instructions (DNA) that tells it what to do. However, sometimes DNA can get damaged.
This damage might change the instructions. A cell might now multiply uncontrollably, or lose a property known as adherence. This refers to how sticky a cell is, and how well it can cling to other surrounding cells and stay where it’s supposed to be.
If a cancer cell loses its adherence, it can break off from the original tumour and travel through the bloodstream or lymphatic system to almost anywhere. This is how metastasis happens.
Many of these travelling cancer cells will die, but some will settle in a new location and begin to form new cancers.
Some cells settle in a new location.
Scipro/ShutterstockParticular cancers are more likely to metastasise to particular organs that help support their growth. Breast cancers commonly metastasise to the bones, liver, and lungs, while skin cancers like melanomas are more likely to end up in the brain and heart.
Unlike cancers which form in solid organs or tissues, blood cancers like leukaemia already move freely through the bloodstream, but can escape to settle in other organs like the liver or brain.
When do cancers metastasise?
The longer a cancer grows, the more likely it is to metastasise. If not caught early, a patient’s cancer may have metastasised even before it’s initially diagnosed.
Metastasis can also occur after cancer treatment. This happens when cancer cells are dormant during treatment – drugs may not “see” those cells. These invisible cells can remain hidden in the body, only to wake up and begin growing into a new cancer months or even years later.
For patients who already have cancer metastases at diagnosis, identifying the location of the original tumour – called the “primary site” – is important. A cancer that began in the breast but has spread to the liver will probably still behave like a breast cancer, and so will respond best to an anti-breast cancer therapy, and not anti-liver cancer therapy.
As metastases can sometimes grow faster than the original tumour, it’s not always easy to tell which tumour came first. These cancers are called “cancers of unknown primary” and are the 11th most commonly diagnosed cancers in Australia.
One way to improve the treatment of metastatic cancer is to improve our ways of detecting and identifying cancers, to ensure patients receive the most effective drugs for their cancer type.
What increases the chances of metastasis and how can it be prevented?
If left untreated, most cancers will eventually acquire the ability to metastasise.
While there are currently no interventions that specifically prevent metastasis, cancer patients who have their tumours surgically removed may also be given chemotherapy (or other drugs) to try and weed out any hidden cancer cells still floating around.
The best way to prevent metastasis is to diagnose and treat cancers early. Cancer screening initiatives such as Australia’s cervical, bowel, and breast cancer screening programs are excellent ways to detect cancers early and reduce the chances of metastasis.
The best way to prevent cancer spreading is to diagnose and treat them early.
Peakstock/ShutterstockNew screening programs to detect cancers early are being researched for many types of cancer. Some of these are simple: CT scans of the body to look for any potential tumours, such as in England’s new lung cancer screening program.
Using artificial intelligence (AI) to help examine patient scans is also possible, which might identify new patterns that suggest a cancer is present, and improve cancer detection from these programs.
More advanced screening methods are also in development. The United States government’s Cancer Moonshot program is currently funding research into blood tests that could detect many types of cancer at early stages.
One day there might even be a RAT-type test for cancer, like there is for COVID.
Will we be able to prevent metastasis in the future?
Understanding how metastasis occurs allows us to figure out new ways to prevent it. One idea is to target dormant cancer cells and prevent them from waking up.
Directly preventing metastasis with drugs is not yet possible. But there is hope that as research efforts continue to improve cancer therapies, they will also be more effective at treating metastatic cancers.
For now, early detection is the best way to ensure a patient can beat their cancer.

Is Your Gut Leading You Into Osteoporosis?

Bacterioides Vulgatus & Bone Health
We’ve talked before about the importance of gut health:
And we’ve shared quite some information and resources on osteoporosis:
- The Bare-bones Truth: Osteoporosis Mythbusting
- Osteoporosis Exercises (What To Do, And What To Avoid)
- Vit D + Calcium: Too Much Of A Good Thing?
- Collagen For Bones: We Are Such Stuff As Fish Are Made Of
- Which Osteoporosis Medication, If Any, Is Right For You?
How the two are connected
A recent study looked at Bacterioides vulgatus, a very common gut bacterium, and found that it suppresses the gut’s production of valeric acid, a short-chain fatty acid that enhances bone density:
❝For the study, researchers analyzed the gut bacteria of more than 500 peri- and post-menopausal women in China and further confirmed the link between B. vulgatus and a loss of bone density in a smaller cohort of non-Hispanic White women in the United States.❞
Pop-sci source: Does gut bacteria cause osteoporosis?
The study didn’t stop there, though. They proceeded to test, with a rodent model, the effect of giving them either:
- more B. vulgatus, or
- valeric acid supplements
The results of this were as expected:
- Those who were given more B. vulgatus got worse bone microstructure
- Those who were given valeric acid supplements got stronger bones overall
Study source: Gut microbiota impacts bone via Bacteroides vulgatus-valeric acid-related pathways
Where can I get valeric acid?
We couldn’t find a handy supplement for this, but it is in many foods, including avocados, blueberries, cocoa beans, and an assortment of birds.
Click here to see a more extensive food list (you’ll need to scroll down a little)
Bonus: if you happen to be on HRT in the form of Estradiol valerate (e.g: Progynova), then that “valerate” is an ester of valeric acid, that your body can metabolize and use as such.
Enjoy!

Stick with It – by Dr. Sean Young
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Most of us know the theory when it comes to building new habits and/or replacing old ones, and maybe we even implement those ideas. So why is our success rate still not as high as we think it should be?
Dr. Sean Young is here to do science to it!
This book comes with advice and explanations that rely a lot less on “that sounds reasonable” and a lot more on “in this recent high-quality study, researchers found…”
And, at 10almonds, we love that. We’re all for trying new things that sound reasonable in general… but we definitely prefer when there’s a stack of solid science to point to, and that’s the kind of thing we recommend!
Dr. Young is big on using that science to find ways to trick our brains and get them working the way we want.
Each chapter has lots of science, lots of explanations, and lots of actionable step-by-step advice.
Bottom line: if you’re all over “Atomic Habits”, this one’s the science-based heavy-artillery for your practical neurohacking.
