Exercise may protect against cognitive decline


Exercise may protect against cognitive decline

A new study conducted by researchers at the University of Miami in Florida, suggests exercise in older age may slow the rate of cognitive decline and knock off a decade of the brain.

Researchers found that adults over the age of 50 who engaged in light or no exercise showed a significantly faster decline in memory and cognitive skills, compared with those who engaged in moderate to intense exercise.

Similar research in the past suggested that any amount of exercise may reduce the risk of Alzheimer's disease by 50%.

Although, these types of studies are in abundance, researchers say it is important to understand how cognitive decline may be slowed by lifestyle factors, especially with an ageing population.

Dr.Clinton B. Wright, of the University of Miami in Florida notes:

"The number of people over the age of 65 in the United States is on the rise, meaning the public health burden of thinking and memory problems will likely grow.”

"Our study showed that for older people, getting regular exercise may be protective, helping them keep their cognitive abilities longer."

For the study, the researchers evaluated data of 876 adults aged 50 and older - an average age of 71 - free of memory and thinking problems that were part of the Northern Manhattan Study.
Participants were asked how often they had exercised in the previous 2 weeks and how long they had exercised for.


Almost 90% of the participants said they engaged in either light exercise or no exercise at all. The other 10% reported engaging in moderate to high-intensity exercise, such as running, aerobics or calisthenics.

Approximately seven years later, participants had to take part in memory and thinking tests and undergo brain imaging with Magnetic Resonance Imaging (MRI). The same cognitive tests were completed again five years later.

Participants who engaged in light or no exercise demonstrated a decline in memory and thinking skills compared with participants who did moderate or high-intensity exercise over a 5-year period. Researchers said the difference was comparable to 10 years of ageing.

According to the research team, this association remained after accounting for a number of potentially confounding factors, including alcohol consumption, smoking, body mass index (BMI) and blood pressure.

Dr. Wright said:

"Physical activity is an attractive option to reduce the burden of cognitive impairment in public health because it is low cost and doesn't interfere with medications.

Our results suggest that moderate to intense exercise may help older people delay aging of the brain, but more research from randomized clinical trials comparing exercise programs to more sedentary activity is needed to confirm these results."

The study was published online in the journal Neurology.

  1. My name is Olisa Blessing, I feel so decent. I never thought I would be this healthy again in my life. I have worked as an air hostess ( cabin crew ) for 3years but early this year, I lost my job because of this deadly disease called Herpes virus (HSV). I never felt sick or notice any symptoms. Not until the day all workers were asked to bring their doctors report card, that was how I got tested and I found out that I'm HSV positive and that made me lose my job because it was considered as an STD and is an incurable disease. I was so depressed that I started thinking of suicide.
    I explained my situation to an older friend of mine, who often said to me 'a problem shared is a problem half solved. She felt so pity for me that she referred me to Dr. Utu Herbal Cure, that was how I contacted Dr. Utu and got the medication from him and was cured for real.
    I went back to my work a month later with another HSV negative test result and they carried out another test to be very sure and they found out I am negative.
    Finally, the initial test was replaced with a negative result and my position was restored to me with an apology letter and a salary increment.
    Beware of impersonators,
    Dr. Utu can only be reached at:

  2. I was able to overcome senile dementia via a complete naturopathic procedure.

    About two years ago, when I was 56, I started feeling foggy and had occasional memory lapses. My wife, Mary, started to notice it, too, but I also have hearing issues so she thought that was the trouble. My memory problems deepened very gradually over the years, and we lived with it, compensating as needed. I became less social. After some months thereafter, it got to the point where we couldn’t keep making excuses or ignoring it. I had gone from doing our grocery shopping without a list to going with a list, to having the list but not buying what was on it.

    Mary went online to do some research, and it was during this process we had been fortunate enough to come across Dr. Utu Herbal Cure: an African herbalist and witch doctor whose professional works had majored on the eradication of certain viral conditions, especially dementia, ( improving the memory capacity positively), via a traditional, naturopathic process and distinguished diet plan. It was by the administration of this herbal specialist that I had been able to improve my condition for better. So to say, the encounter with the above-mentioned herbal practitioner was the first time we ever heard there was something that possibly can be done to improve my memory functionality.

    By the existence of such an encounter, I was able to learn of the new approach by which this herbalist successfully treated dementia conditions, which included a distinguished herbal therapy and lifestyle changes of which I had undergone to a tremendous, positive effect.
    It was after the completion of the herbal therapy I had started to experience a great deal of cognitive improvement when it came to rational decision making.

    In brief, I was able to go through the dreadful hollows of senile dementia without any further hazardous damage to my health condition, and within a short period. Had it not been for the support of my wife, of whom had encouraged me to undergo the above-mentioned therapy and that of the herbal practitioner of whom now happens to be benefactor - I would have been long exposed to the further perils of this condition and of which had been apt to result to a calamitous end.

    I would also wish for the same positiveness upon patients who may happen to be suffering from this debilitating disease, and would warmly beseech them to find a confidant like this herbal specialist with whose professional services I was able to attain a divine recovery.
