25 Simple Steps to Prevent Alzheimer's
Alzheimer’s
strikes fear in all of us. The thought of losing your mind as you grow
older is terrifying and made worse by the fact that, before now, there
appeared to be little we could do to slow down or avoid Alzheimer’s, the
most common form of dementia.
However
research has found a lot of factors that raise or diminish the risk of
Alzheimer's disease. Following these tips, you could slash your chances
of developing the disease:
1. Check out your ankle
Low
blood flow in your foot is a clue to trouble in your brain and a simple
test can reveal its cognitive state and your likelihood of stroke and
dementia. The theory is blood vessel health is similar throughout the
body. The degree of clogged arteries and blood flow in the feet can
suggest atherosclerosis in cerebral blood vessels. Ask your doctor for
an ankle-brachial index (ABI) test which involves an ultrasound device
and a blood pressure cuff that compares blood pressure in your ankle
with that in your arm. To remedy any impairment of blood flow your GP
may advise stepped-up exercise or a change in diet/medication.
2. Anti-oxidant-rich foods
Certain
foods infuse your brain with antioxidants that can slow memory decline
and help prevent Alzheimer’s. All fruit and vegetables are good but top
of the list are black raspberries, elderberries, raisins and
blueberries.
3. Beware of bad fats
The
type of fat you eat changes your brain’s functioning for better or
worse. Stay away from saturated fats which strangle brain cells causing
them to become inefficient. Buy low fat or fat-free dairy products
including milk, cheese and ice cream. Cut down on deep-fried foods.
4. Grow a bigger brain
Your
brain starts to shrink when you reach 30 or 40 so it takes longer to
learn. However scientists now believe you can increase the size of your
brain through the act of learning. Try studying, learning new things or
broadening your circle of friends for stimulation.
5. Chocolate Treat
Cocoa,
the main ingredient in chocolate, has sky-high concentrations of
antioxidants called flavanols, which possess strong heart and
brain-protecting properties. Drinking cocoa increases blood flow to the
brain. Cocoa powder has twice as many flavanols as dark chocolate which
has twice a many as milk chocolate. White chocolate has zero.
6. The oestrogen evidence
Sixty
eight per cent of Alzheimer’s patients are women, possibly as midway
through life they lose the protection of the hormone oestrogen which
boosts memory. Unless your GP says otherwise, start taking oestrogen
immediately at the time of menopause – starting any later risks dementia
and strokes.
7. Raise good cholesterol
It’s
well known that having high good-type HDL blood cholesterol protects
you from heart disease. But it can also save your brain. Researchers
claim it blocks sticky stuff that destroys brain cells and acts as an
anti-inflammatory to lessen brain damage. Ways to ramp up good
cholesterol include exercise, drinking moderate amounts of alcohol and
losing weight.
8. Google something
Doing an internet search can stimulate ageing brains even more than reading a book.
And
MRI scans show that savvy surfers have twice as many sparks of brain
activity as novices. Go online to search for information, things to buy
or games to play. Although it’s not known how much it will benefit your
brain, it’s better than passive pursuits.
9. The ApoE4 gene
One
in four of you reading this has a specific genetic time bomb that makes
you three to 10 times more susceptible to developing late-onset
Alzheimer’s. The gene is called apolipoprotein E4. If you inherit a
single variant of ApoE4 from one parent, your Alzheimer’s risk triples.
If you inherit a double dose from both parents, your risk rises by 10
times. Ask your doctor about a DNA test to reveal your ApoE4 genotype.
10. Say yes to coffee
Coffee
is emerging as a tonic for the ageing brain. It is anti-inflammatory,
helps block the ill effects of cholesterol in the brain and cuts the
risks of stroke, depression and diabetes, all promoters of dementia. It
is also high in antioxidants and caffeine which stop neuronal death and
lessen diabetes, high blood pressure and strokes that bring on dementia.
For most people, a moderate daily intake of coffee, two to four cups,
won’t hurt and may help.
11. Dangers of underweight
Unexplained
weight loss after age 60 or so may be a sign of Alzheimer’s. A study
showed that women with the disease started losing weight at least 10
years before dementia was diagnosed. Among women of equal weight, those
who went on to develop dementia slowly became thinner over three decades
and, when diagnosed, weighed an average 12lb less that women who were
free of Alzheimer’s. Talk to your doctor about unexplained weight loss
after 60.
12. Drink wine
A
daily glass of wine may help delay dementia. Research says that alcohol
is an anti-inflammatory and raises good cholesterol which helps ward
off dementia. High antioxidants in red wine give it additional
anti-dementia clout. Such antioxidants act as artery relaxants, dilating
blood vessels and increasing blood flow which encourages cognitive
functioning.
13. Know the early signs
Memory
problems are not the first clue. You may notice a decline in depth
perception, for example you reach to pick up a glass of water and miss
it. Or you misjudge the distance in walking across a street.
Doing
a jigsaw puzzle or reading a map may also be confusing. Losing your
sense of smell can also be an early clue, as well as asking the same
question repeatedly or misplacing belongings in odd places (like putting
keys in the fridge). Be aware of memory problems as the earlier the
signs are spotted, the more successful lifestyle changes and medications
are likely to be.
14. Mediterranean diet
The
Mediterranean diet, no matter where you live, can help save your brain
from memory deterioration and dementia. Studies consistently find that
what the Greeks and Italians eat is truly brain food. Following this
diet – rich in green leafy vegetables, fish, fruits, nuts, legumes,
olive oil and a little vino – can cut your chances of Alzheimer’s by
nearly half. Rather than depending on just one food or a few nutrients,
it is a rich menu of many complex brain benefactors, including an array
of antioxidants, which shield brain cells from oxidative damage.
15. Middle Age Obesity
Your
brain cares if you are fat. A study showed obese people had 8% less
brain tissue and overweight people had 4% less brain tissue than normal
weight people, which according to one scientist hugely increases the
risk of Alzheimer’s. Moreover, brain shrinkage
occurred
in areas of the brain targeted by Alzheimer’s, and which are critical
for planning, long term memory, attention and executive functions, and
control of movement.
Tackle
signs of rising weight early, when you are young or middle aged. Oddly,
being obese after the age of 70 does not raise the risk of Alzheimer’s
but that doesn’t mean you should neglect exercise as it is the best way
of stimulating cognitive functioning and may delay the onset of
Alzheimer’s at any age.
16. Get a good night’s sleep
A
lack of sleep is toxic to brain cells. Sleep has surprising powers to
protect your brain against memory loss and Alzheimer’s. It is a wonder
drug that helps manipulate levels of the dreaded brain toxin peptide
beta-amyloid, a prime instigator of Alzheimer’s, which according to one
scientist puts you at accelerated risk. Research has also found that
sleeping an average of five hours or less a night is linked to large
increases in dangerous visceral abdominal fat, which can cause diabetes
and obesity that can lead to Alzheimer’s. Take naps and seek treatment
for sleep disorders.
17. Have a big social circle
Studying
the brain of a highly sociable 90-year-old woman who died from
Alzheimer’s, researchers in Chicago found that having a large social
network provided her with strong “cognitive reserve” that enabled her
brain to not realise she had Alzheimer’s. Why this happens is a mystery
but interacting with friends and family seems to make the brain more
efficient. It finds alternative routes of communication to bypass broken
connections left by Alzheimer’s. So see friends and family often and
expand your social network. The stronger the brain reserve you build
through life, the more likely you are to stave off Alzheimer’s symptoms.
18. deal with stress
When
you are under stress, your body pours out hormones called
corticosteroids, which can save you in a crisis. But persistent stress
reactions triggered by everyday events like work frustration, traffic
and financial worries can be dangerous. Over time, it can destroy brain
cells and suppress the growth of new ones, actually shrinking your
brain. Sudden traumatic events like the death of a loved one or a
life-changing event like retirement can leave a hangover of severe
psychological stress that precedes dementia. Be aware that chronic
stress can increase older people’s vulnerability to memory decline and
dementia. Seek professional advice. Antidepressants, counselling,
relaxation techniques and other forms of therapy may head off
stress-related memory loss if treated early.
19. Take care of your teeth
Bad
gums may poison your brain. People with tooth and gum disease tend to
score lower in memory and cognition tests, according to US dental
researchers who found that infection responsible for gum disease gives
off inflammatory byproducts that travel to areas of the brain involved
in memory loss.
Consequently,
brushing, flossing and preventing gum disease may help keep your gums
and teeth healthy but also your memory sharper. In another study, older
people with the most severe gingivitis – inflamed gums – were two to
three times more likely to show signs of impaired memory and cognition
than those with the least.
20. Get enough Vitamin B12
As
you age, blood levels of vitamin B12 go down and the chance of
Alzheimer’s goes up. Your ability to absorb it from foods diminishes in
middle age, setting the stage for brain degeneration years later.
Researchers at Oxford University found that a brain running low on B12
actually shrinks and a shortage can lead to brain atrophy by ripping
away, myelin, a fatty protective sheath around neurons. It can also
trigger inflammation, another destroyer of brain cells. Take 500 to
1000mcg of vitamin B12 daily after the age of 40. If you or an older
family member has unexplained memory loss, fatigue or signs of dementia,
be sure to get tested for vitamin B12 deficiency by your GP.
21. Vinegar in everything
There
is plenty of evidence that vinegar sinks risk factors that may lead to
memory decline, namely high blood sugar, insulin resistance, diabetes
and pre-diabetes and weight gain. Researchers in Phoenix, Arizona, have
noted in studies of humans and animals that the acidic stuff packs
potent glucose-lowering effects. Studies have also found it can curb
appetite and food intake, helping prevent weight gain and obesity, which
are associated with diabetes, accelerated dementia and memory loss.
Pour on the vinegar – add it to salad dressings, eat it by the spoonful,
even mix it into a glass of drinking water. Any type of vinegar works.
22. Have your eyes checked
If
you preserve good or excellent vision as you age, your chances of
developing dementia drop by an astonishing 63%. And if it’s poor, just
visiting an optician for an eye test and possible treatment at least
once in later life cuts your dementia odds by about the same amount.
Exactly how vision problems promote dementia is not clear but impaired
vision makes it difficult to participate in mental and physical
activities such as reading and exercising, as well as social activities,
all believed to delay cognitive decline. Be aware that your eyes
reflect and influence how your brain is functioning, especially as you
age. Don’t tolerate poor vision as often it can be corrected.
23. Eat curry
Curry
powder contains the yellow-orange spice turmeric, packed with curcumin,
a component reported to stall memory decline. One study showed elderly
Indians who ate even modest amounts of curry did better in cognitive
tests. Curcumin works by blocking the build-up of Alzheimer’s-inducing
amyloid plaques (deposits found in the brains of sufferers) then nibbles
away at existing plaques to slow cognitive decline.
It is recommended to eat two or three curries a week, and make it a yellow curry. Otherwise, sprinkle the spices on your food.
24. diabetes control
Having
type 2 diabetes makes you more vulnerable to Alzheimer’s. Studies show
it may double or triple your risk and the earlier diabetes takes hold,
the higher the odds of dementia. Some experts refer to Alzheimer’s as
“diabetes of the brain”. The two disorders have similar causes –
obesity, high blood pressure, high cholesterol, high fat and high sugar
diets, low physical activity as well as high blood sugar. In short,
diabetes can deliver a double whammy to the brain, destroying neurons
and increasing inflammation. Do everything possible to keep blood sugar
levels low and stick to a low-saturated fat diet and regular exercise.
25. Drink more tea
Evidence
suggests that tea stalls the cognitive loss that precedes Alzheimer’s
and that the more tea you drink, the sharper your ageing memory is.
Tea’s secret is no mystery. The leaves are packed with compounds able to
penetrate the blood-brain barrier and block neuronal damage.
One
particular green tea antioxidant can block the toxicity of
beta-amyloid, which kills brain cells. Make a point of drinking black
and green tea. Don’t add milk, it can reduce tea’s antioxidant activity
by 25%.
