What’s the difference? is a new editorial product that explains the similarities and differences between commonly confused health and medical terms, and why they matter.
Changes in thinking and memory as we age can occur for a variety of reasons. These changes are not always cause for concern. But when they begin to disrupt daily life, it could indicate the first signs of dementia.
Another term that can crop up when we’re talking about dementia is Alzheimer’s disease, or Alzheimer’s for short.
So what’s the difference?
What is dementia?
Dementia is an umbrella term used to describe a range of syndromes that result in changes in memory, thinking and/or behaviour due to degeneration in the brain.
To meet the criteria for dementia these changes must be sufficiently pronounced to interfere with usual activities and are present in at least two different aspects of thinking or memory.
For example, someone might have trouble remembering to pay bills and become lost in previously familiar areas.
It’s less-well known that dementia can also occur in children. This is due to progressive brain damage associated with more than 100 rare genetic disorders. This can result in similar cognitive changes as we see in adults.
So what’s Alzheimer’s then?
Alzheimer’s is the most common type of dementia, accounting for about 60-80% of cases.
So it’s not surprising many people use the terms dementia and Alzheimer’s interchangeably.
Changes in memory are the most common sign of Alzheimer’s and it’s what the public most often associates with it. For instance, someone with Alzheimer’s may have trouble recalling recent events or keeping track of what day or month it is.
We still don’t know exactly what causes Alzheimer’s. However, we do know it is associated with a build-up in the brain of two types of protein called amyloid-β and tau.
While we all have some amyloid-β, when too much builds up in the brain it clumps together, forming plaques in the spaces between cells. These plaques cause damage (inflammation) to surrounding brain cells and leads to disruption in tau. Tau forms part of the structure of brain cells but in Alzheimer’s tau proteins become “tangled”. This is toxic to the cells, causing them to die. A feedback loop is then thought to occur, triggering production of more amyloid-β and more abnormal tau, perpetuating damage to brain cells.
Alzheimer’s can also occur with other forms of dementia, such as vascular dementia. This combination is the most common example of a mixed dementia.
Vascular dementia
The second most common type of dementia is vascular dementia. This results from disrupted blood flow to the brain.
Because the changes in blood flow can occur throughout the brain, signs of vascular dementia can be more varied than the memory changes typically seen in Alzheimer’s.
For example, vascular dementia may present as general confusion, slowed thinking, or difficulty organising thoughts and actions.
Your risk of vascular dementia is greater if you have heart disease or high blood pressure.
Frontotemporal dementia
Some people may not realise that dementia can also affect behaviour and/or language. We see this in different forms of frontotemporal dementia.
The behavioural variant of frontotemporal dementia is the second most common form (after Alzheimer’s disease) of younger onset dementia (dementia in people under 65).
People living with this may have difficulties in interpreting and appropriately responding to social situations. For example, they may make uncharacteristically rude or offensive comments or invade people’s personal space.
Semantic dementia is also a type of frontotemporal dementia and results in difficulty with understanding the meaning of words and naming everyday objects.
Dementia with Lewy bodies
Dementia with Lewy bodies results from dysregulation of a different type of protein known as α-synuclein. We often see this in people with Parkinson’s disease.
So people with this type of dementia may have altered movement, such as a stooped posture, shuffling walk, and changes in handwriting. Other symptoms include changes in alertness, visual hallucinations and significant disruption to sleep.
Do I have dementia and if so, which type?
If you or someone close to you is concerned, the first thing to do is to speak to your GP. They will likely ask you some questions about your medical history and what changes you have noticed.
Sometimes it might not be clear if you have dementia when you first speak to your doctor. They may suggest you watch for changes or they may refer you to a specialist for further tests.
There is no single test to clearly show if you have dementia, or the type of dementia. A diagnosis comes after multiple tests, including brain scans, tests of memory and thinking, and consideration of how these changes impact your daily life.
Not knowing what is happening can be a challenging time so it is important to speak to someone about how you are feeling or to reach out to support services.
Dementia is diverse
As well as the different forms of dementia, everyone experiences dementia in different ways. For example, the speed dementia progresses varies a lot from person to person. Some people will continue to live well with dementia for some time while others may decline more quickly.
There is still significant stigma surrounding dementia. So by learning more about the various types of dementia and understanding differences in how dementia progresses we can all do our part to create a more dementia-friendly community.
The National Dementia Helpline (1800 100 500) provides information and support for people living with dementia and their carers. To learn more about dementia, you can take this free online course.

What’s the difference between ADD and ADHD?
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.
Around one in 20 people has attention-deficit hyperactivity disorder (ADHD). It’s one of the most common neurodevelopmental disorders in childhood and often continues into adulthood.
ADHD is diagnosed when people experience problems with inattention and/or hyperactivity and impulsivity that negatively impacts them at school or work, in social settings and at home.
Some people call the condition attention-deficit disorder, or ADD. So what’s the difference?
In short, what was previously called ADD is now known as ADHD. So how did we get here?
Let’s start with some history
The first clinical description of children with inattention, hyperactivity and impulsivity was in 1902. British paediatrician Professor George Still presented a series of lectures about his observations of 43 children who were defiant, aggressive, undisciplined and extremely emotional or passionate.
Since then, our understanding of the condition evolved and made its way into the Diagnostic and Statistical Manual of Mental Disorders, known as the DSM. Clinicians use the DSM to diagnose mental health and neurodevelopmental conditions.
The first DSM, published in 1952, did not include a specific related child or adolescent category. But the second edition, published in 1968, included a section on behaviour disorders in young people. It referred to ADHD-type characteristics as “hyperkinetic reaction of childhood or adolescence”. This described the excessive, involuntary movement of children with the disorder.
It took a while for ADHD-type behaviour to make in into the diagnostic manual. Elzbieta Sekowska/Shutterstock In the early 1980s, the third DSM added a condition it called “attention deficit disorder”, listing two types: attention deficit disorder with hyperactivity (ADDH) and attention deficit disorder as the subtype without the hyperactivity.
However, seven years later, a revised DSM (DSM-III-R) replaced ADD (and its two sub-types) with ADHD and three sub-types we have today:
- predominantly inattentive
- predominantly hyperactive-impulsive
- combined.
Why change ADD to ADHD?
ADHD replaced ADD in the DSM-III-R in 1987 for a number of reasons.
First was the controversy and debate over the presence or absence of hyperactivity: the “H” in ADHD. When ADD was initially named, little research had been done to determine the similarities and differences between the two sub-types.
The next issue was around the term “attention-deficit” and whether these deficits were similar or different across both sub-types. Questions also arose about the extent of these differences: if these sub-types were so different, were they actually different conditions?
Meanwhile, a new focus on inattention (an “attention deficit”) recognised that children with inattentive behaviours may not necessarily be disruptive and challenging but are more likely to be forgetful and daydreamers.
People with inattentive behaviours may be more forgetful or daydreamers. fizkes/Shutterstock Why do some people use the term ADD?
There was a surge of diagnoses in the 1980s. So it’s understandable that some people still hold onto the term ADD.
Some may identify as having ADD because out of habit, because this is what they were originally diagnosed with or because they don’t have hyperactivity/impulsivity traits.
Others who don’t have ADHD may use the term they came across in the 80s or 90s, not knowing the terminology has changed.
How is ADHD currently diagnosed?
The three sub-types of ADHD, outlined in the DSM-5 are:
- predominantly inattentive. People with the inattentive sub-type have difficulty sustaining concentration, are easily distracted and forgetful, lose things frequently, and are unable to follow detailed instructions
- predominantly hyperactive-impulsive. Those with this sub-type find it hard to be still, need to move constantly in structured situations, frequently interrupt others, talk non-stop and struggle with self control
- combined. Those with the combined sub-type experience the characteristics of those who are inattentive and hyperactive-impulsive.
ADHD diagnoses continue to rise among children and adults. And while ADHD was commonly diagnosed in boys, more recently we have seen growing numbers of girls and women seeking diagnoses.
However, some international experts contest the expanded definition of ADHD, driven by clinical practice in the United States. They argue the challenges of unwanted behaviours and educational outcomes for young people with the condition are uniquely shaped by each country’s cultural, political and local factors.
Regardless of the name change to reflect what we know about the condition, ADHD continues to impact educational, social and life situations of many children, adolescents and adults.

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.

10 Tips To Reduce Morning Pain & Stiffness With Arthritis
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.
Physiotherapist and osteoarthritis specialist Dr. Alyssa Kuhn has professional advice:
Just the tips
We’ll not keep them a mystery; they are:
- Perform movements that target the range of motion in stiff joints, especially in knees and hips, to prevent them from being stuck in limited positions overnight.
- Use relaxation techniques like a hot shower, heating pad, or light reading before bed to reduce muscle tension and stiffness upon waking.
- Manage joint swelling during the day through gentle movement, compression sleeves, and self-massage .
- Maintain a balanced level of activity throughout the day to avoid excessive stiffness from either overactivity or, on the flipside, prolonged inactivity.
- Use pillows to support joints, such as placing one between your knees for hip and knee arthritis, and ensure you have a comfortable pillow for neck support.
- Eat anti-inflammatory foods prioritizing fruits and vegetables to reduce joint stiffness, and avoid foods high in added sugar, trans-fats, and saturated fats.
- Perform simple morning exercises targeting stiff areas to quickly relieve stiffness and ease into your daily routine.
- Engage in strength training exercises 2–3 times per week to build stronger muscles around the joints, which can reduce stiffness and pain.
- Ensure you get 7–8 hours of restful sleep, as poor sleep can increase stiffness and pain sensitivity the next day. 10almonds note: we realize there’s a degree of “catch 22” here, but we’re simply reporting her advice. Of course, do what you can to prioritize being able to get the best quality sleep you can.
- Perform gentle movements or stretches before bed to keep joints limber, focusing on exercises that feel comfortable and soothing.

Intermittent Fasting for Women Over 50 – by Emma Sanchez
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.
Intermittent fasting is promoted as a very healthful (evidence-based!) way to trim the fat and slow aging, along with other health benefits. But, physiologically and especially metabolically, the average woman is quite different from the average man! And most resources are aimed at men. So, what’s the difference?
Emma Sanchez gives an overview not just of intermittent fasting, but also, how it goes with specifically female physiology. From hormonal cycles, to different body composition and fat distribution, to how we simply retain energy better—which can be a mixed blessing!
We’re given advice about how to optimize all those things and more.
She also covers issues that many writers on the topic of intermittent fasting will tend to shy away from, such as:
- mood swings
- risk of eating disorder
- impact on cognitive thinking
…and she does this evenly and fairly, making the case for intermittent fasting while acknowledging potential pitfalls that need to be recognized in order to be managed.
Lastly, the “over 50” thing. This is covered in detail quite late in the book, but there are a lot of changes that occur (beyond the obvious!), and once again, Sanchez has tips and tricks for holding back the clock where possible, and working with it rather than against it, when appropriate.
All in all, a great book for any woman over 50, or really also for women under 50, especially if that particular milestone is on the horizon.

Can Ginkgo Tea Be Made Safe? (And Other Questions)
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.
It’s Q&A Day at 10almonds!
Have a question or a request? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝I’d be interested in OTC prostrate medication safety and effectiveness.❞
Great idea! Sounds like a topic for a main feature one day soon, but while you’re waiting, you might like this previous main feature we did, about a supplement that performs equally to some prescription BPH meds:
❝Was very interested in the article on ginko bilboa as i moved into a home that has the tree growing in the backyard. Is there any way i can process the leaves to make a tea out of it.❞
Glad you enjoyed! First, for any who missed it, here was the article on Ginkgo biloba:
Ginkgo Biloba, For Memory And, Uh, What Else Again?
Now, as that article noted, Ginkgo biloba seeds and leaves are poisonous. However, there are differences:
The seeds, raw or roasted, contain dangerous levels of a variety of toxins, though roasting takes away some toxins and other methods of processing (boiling etc) take away more. However, the general consensus on the seeds is “do not consume; it will poison your liver, poison your kidneys, and possibly give you cancer”:
Ginkgo biloba L. seed; A comprehensive review of bioactives, toxicants, and processing effects
The leaves, meanwhile, are much less poisonous with their ginkgolic acids, and their other relevant poison is very closely related to that of poison ivy, involving long-chain alkylphenols that can be broken down by thermolysis, in other words, heat:
However, this very thorough examination of the potential health benefits and risks of ginkgo tea, comes to the general conclusion “this is not a good idea, and is especially worrying in elders, and/or if taking various medications”:
In summary:
- Be careful
- Avoid completely if you have a stronger-than-usual reaction to poison ivy
- If you do make tea from it, green leaves appear to be safer than yellow ones
- If you do make tea from it, boil and stew to excess to minimize toxins
- If you do make tea from it, doing a poison test is sensible (i.e. start with checking for a skin reaction to a topical application on the inside of the wrist, then repeat at least 6 hours later on the lips, then at least 6 hours later do a mouth swill, then at least 12 hours later drink a small amount, etc, and gradually build up to “this is safe to consume”)
For safety (and legal) purposes, let us be absolutely clear that we are not advising you that it is safe to consume a known poisonous plant, and nor are we advising you to do so.
But the hopefully only-ever theoretical knowledge of how to do a poison test is a good life skill, just in case

From banning junk food ads to a sugar tax: with diabetes on the rise, we can’t afford to ignore the evidence any longer
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.
There are renewed calls this week for the Australian government to implement a range of measures aimed at improving our diets. These include restrictions on junk food advertising, improvements to food labelling, and a levy on sugary drinks.
This time the recommendations come from a parliamentary inquiry into diabetes in Australia. Its final report, tabled in parliament on Wednesday, was prepared by a parliamentary committee comprising members from across the political spectrum.
The release of this report could be an indication that Australia is finally going to implement the evidence-based healthy eating policies public health experts have been recommending for years.
But we know Australian governments have historically been unwilling to introduce policies the powerful food industry opposes. The question is whether the current government will put the health of Australians above the profits of companies selling unhealthy food.
benjamas11/Shutterstock Diabetes in Australia
Diabetes is one of the fastest growing chronic health conditions in the nation, with more than 1.3 million people affected. Projections show the number of Australians diagnosed with the condition is set to rise rapidly in coming decades.
Type 2 diabetes accounts for the vast majority of cases of diabetes. It’s largely preventable, with obesity among the strongest risk factors.
This latest report makes it clear we need an urgent focus on obesity prevention to reduce the burden of diabetes. Type 2 diabetes and obesity cost the Australian economy billions of dollars each year and preventive solutions are highly cost-effective.
This means the money spent on preventing obesity and diabetes would save the government huge amounts in health care costs. Prevention is also essential to avoid our health systems being overwhelmed in the future.
What does the report recommend?
The report puts forward 23 recommendations for addressing diabetes and obesity. These include:
- restrictions on the marketing of unhealthy foods to children, including on TV and online
- improvements to food labelling that would make it easier for people to understand products’ added sugar content
- a levy on sugary drinks, where products with higher sugar content would be taxed at a higher rate (commonly called a sugar tax).
These key recommendations echo those prioritised in a range of reports on obesity prevention over the past decade. There’s compelling evidence they’re likely to work.
Restrictions on unhealthy food marketing
There was universal support from the committee for the government to consider regulating marketing of unhealthy food to children.
Public health groups have consistently called for comprehensive mandatory legislation to protect children from exposure to marketing of unhealthy foods and related brands.
An increasing number of countries, including Chile and the United Kingdom, have legislated unhealthy food marketing restrictions across a range of settings including on TV, online and in supermarkets. There’s evidence comprehensive policies like these are having positive results.
In Australia, the food industry has made voluntary commitments to reduce some unhealthy food ads directly targeting children. But these promises are widely viewed as ineffective.
The government is currently conducting a feasibility study on additional options to limit unhealthy food marketing to children.
But the effectiveness of any new policies will depend on how comprehensive they are. Food companies are likely to rapidly shift their marketing techniques to maximise their impact. If any new government restrictions do not include all marketing channels (such as TV, online and on packaging) and techniques (including both product and brand marketing), they’re likely to fail to adequately protect children.
Food labelling
Food regulatory authorities are currently considering a range of improvements to food labelling in Australia.
For example, food ministers in Australia and New Zealand are soon set to consider mandating the health star rating front-of-pack labelling scheme.
Public health groups have consistently recommended mandatory implementation of health star ratings as a priority for improving Australian diets. Such changes are likely to result in meaningful improvements to the healthiness of what we eat.
Regulators are also reviewing potential changes to how added sugar is labelled on product packages. The recommendation from the committee to include added sugar labelling on the front of product packaging is likely to support this ongoing work.
But changes to food labelling laws are notoriously slow in Australia. And food companies are known to oppose and delay any policy changes that might hurt their profits.
Health star ratings are not compulsory in Australia. BLACKDAY/Shutterstock A sugary drinks tax
Of the report’s 23 recommendations, the sugary drinks levy was the only one that wasn’t universally supported by the committee. The four Liberal and National party members of the committee opposed implementation of this policy.
As part of their rationale, the dissenting members cited submissions from food industry groups that argued against the measure. This follows a long history of the Liberal party siding with the sugary drinks industry to oppose a levy on their products.
The dissenting members didn’t acknowledge the strong evidence that a sugary drinks levy has worked as intended in a wide range of countries.
In the UK, for example, a levy on sugary drinks implemented in 2018 has successfully lowered the sugar content in UK soft drinks and reduced sugar consumption.
The dissenting committee members argued a sugary drinks levy would hurt families on lower incomes. But previous Australian modelling has shown the two most disadvantaged quintiles would reap the greatest health benefits from such a levy, and accrue the highest savings in health-care costs.
What happens now?
Improvements to population diets and prevention of obesity will require a comprehensive and coordinated package of policy reforms.
Globally, a range of countries facing rising epidemics of obesity and diabetes are starting to take such strong preventive action.
In Australia, after years of inaction, this week’s report is the latest sign that long-awaited policy change may be near.
But meaningful and effective policy change will require politicians to listen to the public health evidence rather than the protestations of food companies concerned about their bottom line.
