If the symptoms of Alzheimer’s Disease come about because the
‘electrical’ wiring in the brain gets tangled, then there should be a way of
untangling, should there not? After all, look at the telephone wires in Asia.
They just leave them tangled and run a new set! So is the answer to ‘senior
moments’ re-wiring? Is all I have to do is get my brain hot-wired into a
wireless network plugged into Mr. Google and I can meet the world head on?
However, we’re not quite at the re-wiring yet, so we (you and
me) have to retain as much cerebral function as we can. And it turns out that it
is not all that difficult.
We have known for some time that if you don’t use your
muscles, they waste away. By not using your hands for physical work, the skin on
your hands gets thin. However, we also know that if you use your muscles again,
the muscle tissue builds up and becomes strong once more. If you use your hands
again, the skin builds up and becomes thicker. The message here is that all is
not lost! Recovery is possible.
However, we were always told that the one organ of the body
that could not reverse the wasting process was the Central Nervous System. Once
it started to fail, that was it. Dementia was just around the corner.
Alzheimer’s Disease next week.
That view has been challenged and the results are comforting,
to say the least. Experiments have been carried out that showed that by inducing
stress in an animal resulted in chemicals being released. This on its own was
nothing new, but what was new was the fact that some of these chemicals produced
a difference in the brain’s anatomy! The idea that the brain could not change
was incorrect! It could be ‘short-circuited’ resulting in a new wiring pathway.
What was even more exciting was that if the animal was
restored to its own ‘safe’ and non-threatening environment, then the brain
reverted to its pre-stressed anatomy! It was possible to ‘re-wire’ the brain.
In turn this has led to much research into the effects of
stress and its reversal, and then on to Alzheimer’s Disease (if I have
remembered to spell it correctly)! And if it were possible for its reversal too!
Returning to the research, we have shown that stress can
physically damage nerve cells used in storing memory. We have also found that
mindless watching of the goggle-box also produces a decline in brain function.
In fact the numbers are more worrying than that. It has now been found that
people with no stimulating leisure activities, and who are couch potatoes
instead, are nearly four times more likely to develop dementia compared to those
people who have leisure stimuli and do not waste hours in front of the TV.
Taking that a step further, and turning the scientific data
around to be useful, it has been found that in being the converse to the couch
potato, intellectually stimulating leisure activities had a ‘protective’ effect
for the brain and its capabilities. What is more, they have also found that if
you are doing a job you enjoy, then this was again protective, but a dull job
with no stimulus or challenge was another way to head downhill.
This does not mean that we all have to take up chess
tomorrow, because in place of intellectually stimulating hobbies, it has been
found that physical exercise itself stops memory loss and stimulates growth of
nerve cells.
Another protective factor appears to be marriage! Those who
have never married have twice as high an incidence of dementia than those who
are married. So there you are, rather than say that your wife is driving you
insane, it appears that she is driving you towards sanity instead.
So the secret towards staving off dementia and Al
whatsisname’s disease is to have a job you enjoy, get some exercise, watch a
very limited amount of TV and settle down with a good cook (sorry, that should
have read “a good book”).
