Outdated age is not any barrier to creativity. That is the view of Professor Denis O’Mahony, marketing consultant geriatrician at Cork College Hospital (CUH), who has met many individuals who’ve “remarkably excessive cognition” proper into their 90s.
“I’ve met people who find themselves publishing books and doing all types of artistic issues of their 90s. And you may consider any variety of nice artists who’ve produced a few of their finest work on the finish of their life,” he says, citing Leonard Cohen, Johnny Money and Seamus Heaney. “Many are doing terrific work in older age, not simply within the arts however by engagement in society at massive.”
O’Mahony, who can be affiliate professor within the Division of Medication, UCC, says analysis constantly tells us that individuals with wholesome life-style habits in younger and center maturity normally retain these into previous age, to their profit. “They have a tendency to have higher well being, much less power sickness once they come into their older years, retain their practical bodily and cognitive independence into superior previous age and so they are inclined to stay longer.”
The approach to life habits he’s referring to incorporate avoiding smoking, moderating alcohol consumption, every day train, ordinary social engagement and weight loss program near or absolutely Mediterranean. “These give the mind the very best shot of staying dementia-free,” he says, including that, whereas ideally you’d develop these in youth and middle-age and produce them with you into previous age, it’s by no means too early or too late to start out.
The truth is, it’s estimated that between one-third and 40% of all dementia circumstances consequence from modifiable – preventable – danger components, and O’Mahony says that in 2020 three new modifiable danger components (extreme alcohol consumption, head damage and air air pollution) had been added to the 2017 Lancet Fee’s current 9. These are much less training, hypertension, listening to impairment, smoking, weight problems, melancholy, bodily inactivity, diabetes, and rare social contact.
Well being psychologist and neuroscientist Dr Sabina Brennan’s first ebook,, has the subtitle ‘Maximise your reminiscence, increase your mind well being and defy dementia’.
Brennan says the human mind is kind of resilient and ages comparatively effectively. “We expertise a common kind of slowing, no totally different to not having the ability to run as quick, or rise up off the ground, as rapidly as we used to. It might take just a little longer than earlier than to entry data, however the data’s there – simply as correct as after we had been youthful. We expertise a small decline in reminiscence for latest occasions, which may very well be extra to do with failures in consideration – paying consideration is step one in memory-making.”
Whereas we don’t get off scot free on the subject of the fortunes of our mind as we age, it’s not all downhill. “Illness is the reason for most mind decline, however quite a lot of the decline in mind perform isn’t inevitable,” says Brennan.
Mind ageing doesn’t begin at 60, she says: analysis finds our mind begins to atrophy/shrink from round age 30. And lots of the so-called ‘age-related’ adjustments are the truth is life-style associated.
Brennan says quite a lot of the wholesome life-style issues we cease doing at in regards to the age of 30 would really maintain our mind wholesome.This, she says, is as a result of we attain a cushty level in life and cease stretching ourselves. “But, the life-style components that we cease doing would assist stop mind shrinkage and maintain our mind resilient.”
Even should you develop Alzheimer’s illness, analysis exhibits wholesome life-style habits make you extra resilient to it. Brennan factors to Nineteen Eighties analysis that regarded – after demise – for the distinction between the mind of an individual identified with Alzheimer’s illness and the mind of a similarly-aged individual with out that prognosis. “Alzheimer’s is characterised by plaques and tangles within the mind. The researchers made the wonderful discovery that 10 folks within the management group – with no prognosis – had adequate illness of their mind for a prognosis, but they’d by no means manifested any signs.”
The invention exploded scientific curiosity within the query: why had been these folks resilient to Alzheimer’s illness? “The information is kind of good however it’s not a get-out-free card,” says Brennan, explaining that the symptom-less folks had constructed up resilience, by making and sustaining easy however efficient life-style habits, enabling them to face up to the illness of their mind.
“That they had reserves of their mind that allowed continued perform regardless of the illness current of their mind. So it comes all the way down to – not how a lot illness you will have in your mind – however how a lot wholesome mind you will have.”
There’s a caveat although. Brennan says such folks – as a result of Alzheimer’s is progressive – do attain a tipping level when there’s an excessive amount of illness for the mind to manage and the individual then will get signs.
Nevertheless it’s nonetheless a optimistic message. “The individual with resilience – increased reserve ranges – will get to carry onto their cognitive perform and stay independently for longer than they’d have. And this reserve is linked to life-style components, which suggests we will construct ourselves up by making brain-healthy life-style decisions.”
Brennan divides these brain-healthy decisions into three teams:
Bodily, psychological and social. All are essential for encouraging neuroplasticity (mind skill to adapt to vary and to develop new connections between mind cells). “We’ve 86 billion mind cells, all speaking with one another and the remainder of our physique’s cells by electrical and chemical indicators. Your mind’s consistently speaking to function you.”
Whereas the mind’s simply two per cent of physique weight, it consumes about 25% of our dietary consumption. “It’s a extremely high-energy organ. And this gas, together with oxygen, is delivered by our cardiovascular system. So what’s good for our coronary heart is sweet for our mind – the extra bodily energetic we’re, the higher our cardiovascular system can service our mind.
Social exercise can be essential – no shock lockdown has been significantly damaging for older folks. “Social interplay and engagement are complicated actions that maintain the mind energetic. Social isolation and loneliness are as detrimental to bodily, psychological and mind well being as smoking and weight problems.”
Lifelong studying is significant for mind well being. Dr Michael Merzenich, Kavli prizewinning neuroscientist, chief scientific officer of California-based Posit Science and described because the ‘godfather of mind plasticity’, strongly advocates that change advantages the mind.
“See life as an increasing course of, not as a contracting course of. Have interaction with the world once more. Search for the surprises in it. Steady studying and residing life in a vigorous important manner are two of the strongest issues for enhancing your mind,” he mentioned in a 2020 interview with late US broadcaster Larry King.
Brennan additionally urges pushing past your consolation zone, looking for novelty. “If you happen to play a musical instrument, push to study a brand new piece or approach. Hearken to a unique style of music. Learn in a unique style. Attempt a unique meals. The mind has to pay quite a lot of consideration when it’s first studying one thing, it has to take a seat up and take discover – and it will get the good thing about neuroplasticity.”
Over-50s with extra optimistic perceptions of ageing stay 7.5 years longer, says Brennan. “Attitudes are highly effective – merely switching older adults’ perceptions of ageing to extra optimistic perceptions improves bodily perform to the identical degree as a six-month train programme.
Dr Joanne Feeney, senior analysis fellow with the Irish Longitudinal Research on Ageing (TILDA), says nearly all of older folks – requested to charge their very own notion of their reminiscence and cognitive skill – say it’s fairly good. “The proportion saying ‘honest’ or ‘poor’ will increase with age. Amongst 75s and over, 30% charge their reminiscence as ‘honest’ or ‘poor’, in contrast with 15% of these aged 58-64.”
Brennan says older adults taking reminiscence exams – if instructed beforehand that ‘reminiscence declines with age’ – carry out extra poorly than these not instructed this. “Giving talks to older adults, I urge them by no means to say ‘senior moments’ or ‘my reminiscence’s going’. It’s a self-fulfilling prophecy – you grow to be what you say,” she says, including that whereas one in three describes older folks as dependent/sick/frail, in actuality solely 5% of over 65s stay in nursing properties/assisted residing.
adequate good high quality sleep’s essential for mind well being. “The mind’s a high-energy organ. It produces quite a lot of metabolic waste, which may solely be cleared once you sleep. Your mind has a job of labor to do at night time, checking out reminiscence, clearing out in order to soak up extra data throughout the day,” says Brennan.
The sleep cycle shifts with age – you are inclined to wake earlier, so must go to mattress earlier. “Many individuals ignore this. They at all times went to mattress at 11pm so that they nonetheless do, although they’re waking at 5am.” Advisable sleep for 18-64-year-olds is seven to 9 hours; for 65 and over, it’s seven to eight. Steadiness and regularity round mealtimes and hydration are additionally necessary for sustaining brain-sharpness – in addition to steadiness between work and play, time spent in entrance of screens and being in nature and between train and restoration time.
Evidently holding your mind sharp as you age comes down merely to residing a full life.

Siobhan Cahill, group dementia care coordinator with HSE in Cork, has these brain-boosting suggestions:
Motion helps to spice up manufacturing of feel-good neurotransmitters (endorphins). Any reasonable cardio exercise that raises a mild sweat – for instance, recreation of tennis, hike or swim can create feel-good endorphins. Get your physique transferring – strolling, gardening, home tasks – so long as it’s cardio, all of it counts in the direction of boosting brain-health.
Like the center, the mind advantages from a weight loss program low in saturated fat and excessive in brightly-coloured fruits and inexperienced greens. Consuming oily fish lubricates our mind – wealthy in omega-3 fat, it seems to dampen irritation within the mind and bump up the creation of latest mind cells. A Mediterranean weight loss program contains excessive consumption of fruit, veg, beans, peas and complicated carbs, with reasonable quantities of fish. Olive oil is the primary fats supply of fats. Consuming a small glass of pink wine throughout dinner is a part of it.
Simply 10 minutes of social interplay can tremendously improve mind efficiency. Any easy social interplay with others could be extra helpful than extra extensively practised mind exercises (enjoying chess, fixing tough crossword puzzles). Be part of a ebook/movie membership, group group, choir or sports activities workforce. Social interplay is a tonic in your mind, stimulating mind cells to develop new connections and strengthening these already fashioned.
Psychological stimulation is a crucial ingredient to staying brain-sharp. Problem/stretch your self. Keep away from getting caught in a rut, at all times doing the identical factor. Attempt extra complicated Sudoku/crosswords. Be taught new talent/new language/bridge/new passion. Develop laptop abilities. Studying something new boosts mind connections and builds cognitive reserves.
Your mind wants it to run easily. Whereas we sleep, recollections are sorted and embedded into mind circuits. Sleep can increase powers of recall.
