If you or a loved one have noticed changes in your memory or thinking as you’ve grown older, this could reflect typical changes that occur with ageing. In some cases though, it might suggest something more, such as the onset of dementia.
The best thing to do if you have concerns is to make an appointment with your GP, who will probably run some tests. Assessment is important because if there is something more going on, early diagnosis can enable prompt access to the right interventions, supports and care.
But current methods of dementia screening have limitations, and testing can be daunting for patients.
Our research suggests virtual reality (VR) could be a useful cognitive screening tool, and mitigate some of the challenges associated with current testing methods, opening up the possibility it may one day play a role in dementia diagnosis.
Where current testing is falling short
If someone is worried about their memory and thinking, their GP might ask them to complete a series of quick tasks that check things like the ability to follow simple instructions, basic arithmetic, memory and orientation.
These sorts of screening tools are really good at confirming cognitive problems that may already be very apparent. But commonly used screening tests are not always so good at detecting early and more subtle difficulties with memory and thinking, meaning such changes could be missed until they get worse.
A clinical neuropsychological assessment is better equipped to detect early changes. This involves a comprehensive review of a patient’s personal and medical history, and detailed assessment of cognitive functions, including attention, language, memory, executive functioning, mood factors and more. However, this can be costly and the testing can take several hours.
Testing is also somewhat removed from everyday experience, not directly tapping into activities of daily living.
Enter virtual reality
VR technology uses computer-generated environments to create immersive experiences that feel like real life. While VR is often used for entertainment, it has increasingly found applications in health care, including in rehabilitation and falls prevention.
Using VR for cognitive screening is still a new area. VR-based cognitive tests generally create a scenario such as shopping at a supermarket or driving around a city to ascertain how a person would perform in these situations.
Notably, they engage various senses and cognitive processes such as sight, sound and spatial awareness in immersive ways. All this may reveal subtle impairments which can be missed by standard methods.
VR assessments are also often more engaging and enjoyable, potentially reducing anxiety for those who may feel uneasy in traditional testing environments, and improving compliance compared to standard assessments.

Most studies of VR-based cognitive tests have explored their capacity to pick up impairments in spatial memory (the ability to remember where something is located and how to get there), and the results have been promising.
Given VR’s potential for assisting with diagnosis of cognitive impairment and dementia remains largely untapped, our team developed an online computerised game (referred to as semi-immersive VR) to see how well a person can remember, recall and complete everyday tasks. In our VR game, which lasts about 20 minutes, the user role plays a waiter in a cafe and receives a score on their performance.
To assess its potential, we enlisted more than 140 people to play the game and provide feedback. The results of this research are published across three recent papers.
Testing our VR tool
In our most recently published study, we wanted to verify the accuracy and sensitivity of our VR game to assess cognitive abilities.
We compared our test to an existing screening tool (called the TICS-M) in more than 130 adults. We found our VR task was able to capture meaningful aspects of cognitive function, including recalling food items and spatial memory.
We also found younger adults performed better in the game than older adults, which echoes the pattern commonly seen in regular memory tests.

In a separate study, we followed ten adults aged over 65 while they completed the game, and interviewed them afterwards. We wanted to understand how this group – who the tool would target – perceived the task.
These seniors told us they found the game user-friendly and believed it was a promising tool for screening memory. They described the game as engaging and immersive, expressing enthusiasm to continue playing. They didn’t find the task created anxiety.
For a third study, we spoke to seven health-care professionals about the tool. Overall they gave positive feedback, and noted its dynamic approach to age-old diagnostic challenges.
However, they did flag some concerns and potential barriers to implementing this sort of tool. These included resource constraints in clinical practice (such as time and space to carry out the assessment) and whether it would be accessible for people with limited technological skills. There was also some scepticism about whether the tool would be an accurate method to assist with dementia diagnosis.
While our initial research suggests this tool could be a promising way to assess cognitive performance, this is not the same as diagnosing dementia. To improve the test’s ability to accurately detect those who likely have dementia, we’ll need to make it more specific for that purpose, and carry out further research to validate its effectiveness.
We’ll be conducting more testing of the game soon. Anyone interested in giving it a go to help with our research can register on our team’s website.

The Most Anti Aging Exercise
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 referenced this (excellent) video before, but never actually put it under the spotlight in one of these features, so here we go!
Deep squats
It’s about deep squats, also called Slav squats, Asian squats, sitting squats, resting squats, or various other names. However, fear not; you don’t need to be Slavic or Asian to do it; you just need to practice.
As for why this is called “anti-aging”, by the way, it’s because being able to get up off the ground is one of the main tests of age-related mobility decline, and if you can deep-squat comfortably, then you can do that easily. And so long as you continue being able to deep-squat comfortably, you’ll continue to be able to get up off the ground easily too, because you have the strength in the right muscles, as well as the suppleness, comfort with range of motion, and balance (those stabilizing muscles are used constantly in a deep squat, whereas Western lifestyle sitting leaves those muscles very neglected and thus atrophied).
Epidemiological note: chairs, couches, and assorted modern conveniences reduce the need for squatting in daily life, leading to stiffness in joints, muscles, tendons, and ligaments. Many adults in developed countries struggle with deep squats due to lack of use, not aging. Which is a problem, because a lack of full range of motion in joints causes wear and tear, leading to chronic pain and degenerative joint diseases. People in countries where squatting is a common resting position have lower incidences of osteoarthritis, for example—contrary to what some might expect, squatting does not harm joints but rather protects them from arthritis and knee pain. Strengthening leg muscles through squatting can alleviate knee pain, whereas knee pain is often worsened by inactivity.
Notwithstanding the thumbnail, which is showing an interim position, one’s feet should be flat on the ground, by the way, and one’s butt should be nearby, just a few inches off the ground (in other words, the position that we see her in for most of this video).
Troubleshooting: if you’re accustomed to sitting in chairs a lot, then this may be uncomfortable at first. Zuzka advises us to go gently, and/but gradually increase our range of motion and (equally importantly) duration in the resting position.
You can use a wall or doorway to partially support you, at first, if you struggle with mobility or balance. Just try to gradually use it less, until you’re comfortable deep-squatting with no support.
Since this is not an intrinsically very exciting exercise, once you build up the duration for which you’re comfortable deep-squatting, it can be good to get in the habit of “sitting” this way (i.e. deep squatting, still butt-off-the-floor, but doing the job of sitting) while doing other things such as working (if you have an appropriate work set-up for that*), reading, or watching TV.
*this is probably easiest with a laptop placed on an object/surface of appropriate height, such as a coffee table or such. As a bonus, having your hands in front of you while working will also bring your center of gravity forwards a bit, making the position easier and more comfortable to maintain. This writer (hi, it’s me) prefers her standing desk for work in general, with a nice ergonomic keyboard and all that, but if using a laptop from time to time, then squatting is a very good option.
In terms of working up duration, if you can only manage seconds to start with, that’s fine. Just do a few more seconds each time, until it’s 30, 60, 120, and so on until it’s 5 minutes, 10, 15, and so on.
You can even start that habit-forming while you’re still in the “seconds at a time” stage! You can deep-squat just for some seconds while you:
- pick up something from the floor
- check on something in the oven
- get something out of the bottom of the fridge
…etc!
For more on all this, plus many visual demonstrations including interim exercises to get you there if it’s difficult for you at first, enjoy:

Beetroot vs Tomato – Which is Healthier?
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.
Our Verdict
When comparing beetroot to tomato, we picked the beetroot.
Why?
Both are great! But we say beetroot comes out on top:
In terms of macros, beetroot has more protein, carbs, and fiber, making it the more nutritionally dense option. It has a slightly higher glycemic index, but also has specific phytochemicals that lower blood sugars and increase insulin sensitivity, more than cancelling that out. So, a clear win for beetroot in this regard.
In the category of vitamins, beetroot has more of vitamins B2, B5, B7, and B9, while tomato has more of vitamins A, C, E, and K. We’d call that a 4:4 tie, but tomato’s margins of difference are greater, so we say tomato wins this round.
When it comes to minerals, beetroot has more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc, while tomatoes are not higher in any mineral. An easy win for beetroot here.
Looking at polyphenols and other remaining phytochemicals, beetroot has most, and especially its betalain content goes a long way. Tomatoes, meanwhile, have a famously high lycopene content (a highly beneficial carotenoid). All in all, it could swing either way based on subjective factors, so we’re saying it’s a tie this time.
Adding up the sections makes for an overall win for beetroot, but by all means enjoy either or both; diversity is good!

The Art Of Letting Go – by Nick Trenton

You may be wondering: is this a basic CBT book? And, for the most part, no, it’s not.
It does touch on some of the time-tested CBT techniques, but a large part of the book is about reframing things in a different way, that’s a little more DBT-ish, and even straying into BA. But enough of the initialisms, let’s give an example:
It can be scary to let go of the past, or of present or future possibilities (bad ones as well as good!). However, it’s hard to consciously do something negative (same principle as “don’t think of a pink elephant”), so instead, look at it as taking hold of the present/future—and thus finding comfort and security in a new reality rather than an old memory or a never-actual imagining.
So, this book has a lot of ideas like that, and if even one of them helps, then it was worth reading.
The writing style is comprehensive, and goes for the “tell them what you’re gonna tell them; tell them; then tell them what you told them” approach, which a) is considered good for learning b) can feel a little like padding nonetheless.
Bottom line: this reviewer didn’t personally love the style, but the content made up for it.

Beyond “Make Your Bed”—life lessons from experience

Beyond “Make Your Bed”—life lessons from experience
This is Admiral William H. McRaven, a former United States Navy four-star admiral who served as the ninth commander of the United States Special Operations Command.
So, for those of us whose day-to-day lives don’t involve coordinating military operations, what does he have to offer?
Quick note: 10almonds’ mission statement is “to make health and productivity crazy simple”.
We tend to focus on the health side of this, and in the category of productivity, it’s often what most benefits our mental health.
We’re writing less for career-driven technopreneurs in the 25–35 age bracket and more for people with a more holistic view of productivity and “a good life well-lived”.
So today’s main feature is more in that vein!
Start each day with an accomplishment
McRaven famously gave a speech (and wrote a book) that began with the advice, “make your bed”. The idea here doesn’t have to be literal (if you’ll pardon the pun). Indeed, if you’re partnered, then depending on schedules and habits, it could be you can’t (sensibly) make your bed first thing because your partner is still in it. But! What you can do is start the day with an accomplishment—however small. A short exercise routine is a great example!
Success in life requires teamwork
We’re none of us an island (except in the bathtub). The point is… Nobody can do everything alone. Self-sufficiency is an illusion. You can make your own coffee, but could you have made the coffee machine, or even the cup? How about, grown the coffee? Transported it? So don’t be afraid to reach out for (and acknowledge!) help from others. Teamwork really does make the dream work.
It’s what’s inside that counts
It’s a common trap to fall into, getting caught up the outside appearance of success, rather than what actually matters the most. We need to remember this when it comes to our own choices, as well as assessing what others might bring to the table!
A setback is only permanent if you let it be
No, a positive attitude won’t reverse a lifelong degenerative illness, for example. But what we can do, is take life as comes, and press on with the reality, rather than getting caught up in the “should be”.
Use failure to your advantage
Learn. That’s all. Learn, and improve.
Be daring in life
To borrow from another military force, the SAS has the motto “Who dares, wins”. Caution has it place, but if we’ve made reasonable preparations*, sometimes being bold is the best (or only!) way forward.
*Meanwhile the Parachute Regiment, from which come 80% of all SAS soldiers, has the motto “Utrinque paratus”, “prepared on all sides”.
Keep courage close
This is about not backing down when we know what’s right and we know what we need to do. Life can be scary! But if we don’t overcome our fears, they can become self-realizing.
Writer’s note: a good example of this is an advice I sometimes gave during my much more exciting (military) life of some decades ago, and it pertains to getting into a knife-fight (top advice for civilians: don’t).
But, if you’re in one, you need to not be afraid of getting cut.
Because if you’re not afraid of getting cut, you will probably get cut.
But if you are afraid of getting cut, you will definitely get cut.
Hopefully your life doesn’t involve knives outside of the kitchen (mine doesn’t, these days, and I like it), but the lesson applies to other things too.
Sometimes the only way out is through.
Be your best at your worst
Sometimes life is really, really hard. But if we allow those moments to drive us forwards, they’re also a place we can find more strength than we ever knew we had.
Keep on swimming
It’s said that the majority in life is about showing up—and often it is. But you have to keep showing up, day after day. So make what you’re doing sustainable for you, and keep on keeping on.

For tennis star Destanee Aiava, borderline personality disorder felt like ‘a death sentence’ – and a relief. What is it?
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.
Last week, Australian Open player Destanee Aiava revealed she had struggled with borderline personality disorder.
The tennis player said a formal diagnosis, after suicidal behaviour and severe panic attacks, “was a relief”. But “it also felt like a death sentence because it’s something that I have to live with my whole life”.
A diagnosis is often associated with therapeutic nihilism. This means it’s viewed as impossible to treat, and can leave clinicians and people with the condition in despair.
In fact, people with this disorder can and do recover with adequate support. Understanding it is caused by trauma is fundamental to effectively treat this complex and poorly understood mental illness.
A stigmatising diagnosis
The name “borderline personality disorder” is confusing and adds greatly to the stigma around it.
Doctors first used “borderline” to describe a condition they believed was in-between two others: neurosis and psychosis.
But this implies the condition is not real in itself, and can invalidate the suffering and distress the person and their loved ones experience.
“Personality disorder” is a judgemental term that describes the very essence of a person – their personality – as flawed.
What is borderline personality disorder?
People with the disorder can express a range of symptoms, but high levels of anxiety – including panic attacks – are usually constant.
Symptoms cluster around four main areas:
- high impulsivity (leading to suicidal thoughts and behaviour, self-harm and other risky behaviours)
- unstable or poor sense of self (including low self-esteem)
- mood disturbances (including intense, inappropriate anger, episodic depression or mania)
- problems in relationships.
People with the disorder greatly fear being abandoned and as a result, commonly have distressing difficulties in interpersonal relationships.
This creates a “push-pull” dynamic with loved ones, as people with borderline personality disorder seek closeness, but push away those they love to test the strength of the relationship.
For example, they may escalate a small issue into a major disagreement to see if the loved one will “stick with them” and reinforce their love.
Conversely, if a loved one appears distant or fed up – for example, is thinking about ending the relationship – the person with borderline personality disorder will make major efforts to “pull” them back. This might look like a flurry of messages, expressions of despair, or even suicidal behaviours.
People with borderline personality disorder greatly fear being abandoned, making relationship issues common. Drazen Zigic/Shutterstock Who does it affect?
The disorder affects one in 100 Australians, although this is likely a conservative estimate, as diagnosis is based on the most severe symptoms.
Women are much more likely to be diagnosed with it than men – but why this is so remains a major debate, with political and sociological factors playing a role in making psychiatric diagnoses. Symptoms usually begin in the mid to late teens.
While an initial response to receiving a diagnosis can be comforting for some, it is commonly seen as a chronic, relapsing condition, meaning symptoms can return after a period of improvement.
Borderline personality disorder can fluctuate in intensity and mimic other conditions such as major depression, bipolar disorder, anxiety disorders and psychosis.
Estimates suggest 26% of presentations at emergency departments for mental health issues are by people diagnosed with personality disorders, particularly borderline personality disorder.
What causes it?
The main cause for borderline personality disorder appears to be trauma in early life, compounded by repeated traumas later.
Early life trauma can lead to biological changes in the brain that cause behavioural, emotional or cognitive shifts, leading to social and relationship issues. This is known as complex post-traumatic stress disorder.
Aiava has acknowledged the disorder is “mainly from childhood trauma”, although she has not given details about her specific experiences.
People with borderline personality disorder usually have complex post-traumatic stress disorder. But complex post-traumatic stress disorder doesn’t always result in a borderline personality disorder diagnosis.
Although the two disorders are not identical, they share many similarities, in particular that they are both caused by complex and repeated trauma.
However those with borderline personality disorder tend to experience more rage, emotional disturbances and have a greater fear of abandonment.
They also face greater stigma, whereas the term “complex post-traumatic stress disorder” doesn’t carry the same negative connotations and focuses on the cause of the condition – trauma – rather than “personality”, leading to better treatment options.
The recognition of the major role of trauma in borderline personality disorder is an important step forward in treating the disorder. But because of the stigma associated with it, using the diagnosis of complex post-traumatic stress disorder maybe a better step forward in the future.
Can it be treated?
There are many effective psychological therapies and other treatments for people with borderline personality disorder or complex post-traumatic stress disorder.
For example, dialectical behavioural therapy is a type of cognitive therapy that helps people learn skills such as tolerating distress, managing relationships, regulating emotions and practising mindfulness.
The treatment of people with post-traumatic stress disorder, including victims of war and rape, has taught us a lot about how to treat complex, underlying trauma. For example, with trauma-focused psychological therapies.
Other new treatments, such as eye movement desensitisation and reprogramming, have also shown to be effective.
Many people with borderline personality disorder who receive treatment and have supportive relationships are able to “outgrow” the condition. Others may need to continue to manage symptoms while pursuing a good quality of life.
Treating trauma, not personality
Rethinking borderline personality disorder as a trauma disorder enables a more effective and understanding approach for those with it.
Understanding what trauma does to the brain means newer, targeted medications can also be used.
For example, our research has shown how the brain’s glutamate system – the chemicals responsible for learning and making sense of one’s environment – is overactive in people with complex post-traumtic stress disorder. Medications that work on the glutumate system may therefore help alleviate borderline personality disorder symptoms.
Educating partners and families about borderline personality disorder, providing them support and co-designing crisis strategies are also important parts of total care. Preventing early life trauma is also critical.

Scheduling Tips for Overrunning Tasks

Your Questions, Our Answers!
Q: Often I schedule time for things, but the task takes longer than I think, or multiplies while I’m doing it, and then my schedule gets thrown out. Any ideas?
A: A relatable struggle! Happily, there are remedies:
- Does the task really absolutely need to be finished today? If not, just continue it in scheduled timeslots until it’s completed.
- Some tasks do indeed need to be finished today (hi, writer of a daily newsletter here!), so it can be useful to have an idea of how long things really take, in advance. While new tasks can catch us unawares, recurring or similar-to-previous tasks can be estimated based on how long they took previously. For this reason, we recommend doing a time audit every now and again, to see how you really use your time.
- A great resource that you should include in your schedule is a “spare” timeslot, ideally at least one per day. Call it a “buffer” or a “backup” or whatever (in my schedule it’s labelled “discretionary”), but the basic idea is that it’s a scheduled timeslot with nothing scheduled in it, and it works as an “overflow” catch-all.
Additionally:
- You can usually cut down the time it takes you to do tasks by setting “Deep Work” rules for yourself. For example: cut out distractions, single-task, work in for example 25-minute bursts with 5-minute breaks, etc
- You can also usually cut down the time it takes you to do tasks by making sure you’re prepared for them. Not just task-specific preparation, either! A clear head on, plenty of energy, the resources you’ll need (including refreshments!) to hand, etc can make a huge difference to efficiency.
