Brain Imaging Identifies Best Memorization
Strategies
Why do some people remember things better than others? An
imaging study has revealed that the brain regions activated
when learning vary depending on the strategy adopted, and
that, of the four main strategies commonly employed by
people, only two result in improved recall.
http://www.memory-key.com/news/2006/news_2006Jul.htm#Strategies
Curry helps older brains
Following on from a study that found mice on a diet rich in
curcumin (the yellow pigment in the curry spice turmeric)
developed 85% few Alzheimer’s plaques than control subjects,
an investigation of 1010 older Asians (between 60 and 93
years) has found that those who ate curry occasionally or
often performed better on a standard test of cognitive
function than those who only ate curry never or rarely.

Vigorous exercise helps children's
grades
A study of sixth graders found that there was no difference
in academic performance for those taking a physical
education course and those taking the non-physical, but that
students who took part in more vigorous physical activities
at least three times a week did better in academic subjects.
http://www.memory-key.com/news/2006/news_2006Jul.htm#exercise
Drug reverses aging effect on memory
process
Rat studies suggest that a drug made to enhance memory
triggers a natural mechanism in the brain that fully
reverses age-related memory loss, even after the drug itself
has left the body.
http://www.memory-key.com/news/2006/news_2006Jul.htm#Drug
How multitasking impedes learning
Another study on how doing two things at once impairs
performance. A new imaging study provides evidence that we
tend to use a less efficient means of learning when
distracted by another task, with the consequence that tasks
learned while distracted are less transferable.
http://www.memory-key.com/news/2006/news_2006Jul.htm#multitasking
Sleep makes memories resistant to
interference
It’s pretty clear now that sleep consolidates procedural
(skill) learning, but the question of whether or not it
helps other types of memory is still very much a matter of
debate. However, a new study has found a marked effect of
sleep on our ability to remember information, providing
clear evidence of sleep’s role in consolidating the memory,
thus making it considerably more resistant to interference
from new information.
http://www.memory-key.com/news/2006/news_2006Jul.htm#Sleep
Support for labeling as an aid to
memory
A study involving an amnesia-inducing drug has shed light on
how we form new memories, reinforcing the idea that the
ability to recollect depends on the ability to link the
stimulus to a context, and that unitization (being able to
label the item with a word or phrase) increases the chances
of this linking occurring.
http://www.memory-key.com/news/2006/news_2006Jul.htm#labeling
Avoiding predators may be the reason
for our large brains
A study of predators in Africa and South America suggests a
new theory for why we evolved big brains — avoiding
predation.
http://www.memory-key.com/news/2006/news_2006Jul.htm#predators
Bigger brains associated with
domain-general intelligence
Analysis of hundreds of studies testing the cognitive
abilities of non-human primates provides support for a
general intelligence, and confirms that the great apes are
more intelligent than monkeys and prosimians.

ALZHEIMER'S NEWS

Predicting dementia risk
A large Scandinavian study has succeeded in calculating
middle-aged people's chances of developing dementia later in
life with 70% accuracy, confirming the importance of
lifestyle factors in preventing Alzheimer’s.
http://www.memory-key.com/Seniors/Alzheimers_2006b.htm#Predicting
Calorie restriction may help prevent
Alzheimer's
A mouse study has found that beta-amyloid peptides can be
reduced by restricting calorie intake, primarily through a
low carbohydrate diet, and that a high caloric intake based
on saturated fat increases levels of beta-amyloid peptides.
http://www.memory-key.com/Seniors/Alzheimers_2006b.htm#Calorie
Apples fight memory loss
A mouse study confirms an earlier study suggesting apples
increase acetylcholine levels and fight memory loss.
http://www.memory-key.com/Seniors/Alzheimers_2006b.htm#Apples
How mental and physical stimulation
slows Alzheimer's
A new study sheds light on how mental and physical activity
slows the cognitive decline seen in Alzheimer’s.
http://www.memory-key.com/Seniors/Alzheimers_2006b.htm#stimulation
Weight Loss Precedes Dementia Diagnosis
In Women
A study has come out finding that, in women, but not in men,
declining weight precedes dementia by many years.
http://www.memory-key.com/Seniors/Alzheimers_2006b.htm#Weight
Elders with dementia can tap into memory stores to give
advice
Surprisingly, it appears that the best way to converse with
an Alzheimer’s patient may be to ask them for advice. In two
studies, researchers found that adults with moderate to
severe symptoms of dementia can still be quite coherent and
informative when asked for advice.
http://www.memory-key.com/Seniors/Alzheimers_2006b.htm#advice
Donezepil slows brain deterioration
for some on road to Alzheimer's
According to a new study, the drug donepezil slows the rate
of hippocampal shrinkage in patients with mild cognitive
impairment who carried the apolipoprotein E4 (APOE 4) gene
variant.
