Aging begins at 45- Tips on how to Prevent Early Memory Loss

Monday, January 9th, 2012



The latest scientific study pins memory loss from aging to the age of 45.  Here are some ways to prevent early onset dementia like Alzheimer’s disease and reclaim your youth.


45- Is it the new 60?

According a recent study on cognitive decline, the first signs of aging, such as memory loss, begin at the age of 45.  The UK study, which tracked 5,198 men and 2,192 women, suggests that people should become more proactive in preventing Alzheimer’s disease much earlier than earlier expected.

  • Participants between the ages of 45-70 submitted to various cognitive testing, including vocabulary, memory, reasoning, and auditory and visual learning abilities.
  • Examples of cognitive testing include identifying patterns, recalling short words, naming words from memory beginning with the letter “S,” or animal names.
  • Scientists met with study volunteers three times during a 10-year period.
  • Results: With the exception of vocabulary, cognitive scores in memory, reasoning, and learning abilities declined in all age groups, beginning at the ages of 45-49, for both men and women.
  • For men and women, dementia escalated by the age of 65-70.
  • Older males saw a 9.6% decline by age 70, while elderly females of the same age exhibited a 7.4% decline.

Here’s Your Brain on B12 Deficiency- Memory Loss and Aging


Lifestyle changes to prevent memory loss

By making some simple changes in your life, you can delay symptoms of aging that include memory loss, confused thinking, fatigue, and hair greying.

Here are some helpful tips:

  • Increase intake of vitamins and minerals, including healthy omega-3 oils, vitamin D, vitamin C, and B complex vitamins, particularly vitamin B12, which is proven to aid in cognitive functioning and maintaining healthy brain mass.
  • Eat low cholesterol, low-fat foods.
  • Avoid high fat or processed foods.
  • Restrict sodium intake.
  • Exercise every day.
  • Check your blood pressure.
  • Quit smoking.

Prevent vitamin B12 deficiency

Numerous studies prove that vitamin B12 is more than just the energy vitamin- it also is essential for brain health and rejuvenation.  Vitamin B12 protects your nervous system, aids in producing red blood cells, builds DNA, and boosts cognitive skills.

  • By controlling homocysteine levels, vitamin B12 helps lower your risk for heart attack and stroke.  Scientists have noticed a high correlation between elevated levels of homocysteine in the blood and increased risk for dying of heart failure or stroke.
  • Scientific research also indicates a direct relationship between low levels of vitamin B12, reduced brain volume, and decreased cognitive skills, such as loss of short-term memory
  • Besides memory loss, other age-related symptoms of vitamin B12 deficiency include premature hair loss, hair greying, fatigue, difficulty walking, difficulty concentrating, and emotional problems like depression and nervousness.

Vitamin B12 and Brain Size

Monday, March 8th, 2010

Vitamin B12 is linked to brain size, and therefore this vitamin may help prevent dementia by maintaining brain volume, according to a study published in Neurology (September 9, 2008).

The study focused on 107 volunteers whose average age was 73 years, ranging from 61 to 87 years old. All participants were required to undergo a physical examination, brain MRI and CT scans. Only people in good physical and mental health were included in this study.

For this study, blood samples were also taken of the volunteers. Tests were done to measure vitamin B12 plasma levels, in addition to levels of homocysteine, folate and methylmalonic acid (MMA). These measurements were taken once a year over the duration of five years.

For all the volunteers, the B12 plasma levels fell within the range of normal.

At the end of the five-year period, the volunteers were again subject to brain scans and memory tests. Subjects who had the most brain loss also had lower concentrations of B12. No correlation was made between brain loss and levels of homocysteine, folate or MMA.

The results of this study demonstrated that those people with lower B12 plasma levels were six times more likely to have a loss of brain volume and a decrease in brain size than those with higher levels. Therefore, the authors of this study have concluded that by increasing the consumption of of vitamin B12 among the elderly can reverse brain shrinkage, and possibly prevent memory loss as well. It is hoped that future clinical trials will determine the affects of vitamin B12 supplementation on brain shrinkage.

In the meantime, the authors of this study would advise the geriatric population to increase their intake of vitamin B12 through meat, fish, milk and fortified cereals.
