So what exactly is Neuropsychology ?

There is a long tradition of a
close working relationship between the sport of boxing, and the
medical profession. It often seems that every time you look at the
rules and regulations, the doctors have added something else, almost
as if they are out to stifle the game with more tests and scans
and the like. So it might come as a surprise to learn that some
doctors are looking at even more tests in an area called neuropsychology.
If we look at the medical requirements
to date, the idea of neuropsychological tests might make a bit more
sense.
The annual physical examination
is fairly straightforward, and gives an indication of your general
health, with checks on pulse blood pressure, eyesight and so on.
Blood test will determine if you
have picked up a viral infection such as hepatitis, which could
be a problem if you get cut in a fight, as blood droplets can splash
as far as the third row!!
Some regulating bodies have introduced
the brain scan, as it will give a picture of the actual inside of
the brain itself. The new MRI scans can give minute detail, showing
up scars and tears of the brain tissue, as well as clots and old
bleeds. The problem with the brain scan is that it will only really
show damage once it has occurred. If a boxer has a series of scans
over a few years, they can be compared, and the appearance of signs
of damage can be seen. By then the damage has been done. The scans
cannot really predict who might come to harm, they can just give
a snapshot picture of the harm once it has occurred.
This is where neuropsychometric
or neuropsychological tests come in, as they might be able to spot
signs of impending damage before they show up on scans. Neuropsychology
is in simple terms a study of behaviour, which tries to link what
we do, to certain areas of the brain.
The psychologists have figured out
that certain bits of the brain are responsible for memory, counting,
sense of smell and so on. By looking at brain specimens from boxers
who fought 50-100 years ago, they have figured out which bits might
get hurt in boxing, and so have devised some simple tests, to monitor
the function of the brain relevant to our sport. Some people might
be worried that this sort of test will be like a school exam, and
only the bright guys will pass. This is not the case. The beauty
of these tests is that they can be done every year, and each boxer
will act as his own benchmark. Whatever he scores at year one, will
be compared with the results he gets over the next few years. The
boxer is compared to himself, and no body else.
So what do the tests involve? The
field of neuropsychology is vast, and so it is important that the
test used are simple, easy to follow and should only take about
20 minutes. Common tests used would involve drawing a figure from
memory, or copying down a code using numbers instead of letters.
Another involves joining the numbers 1-20 like a dot-to-dot puzzle.
The tests may be really simple, but can give a great deal of information
about how the brain is working. This is why some doctors think they
are the way forward. In a tough sport such as boxing we need to
know how the brain is working, not just how it looks on a scan.
The good comparison would be when
you go to buy a new car. Would you just look at a photograph and
say, “ looks fine to me. …I’ll take it “ . I hope not ! you would
want to take the car out for a drive to see how it handled, check
that the brakes and lights , radio and air conditioning were all
working…you need to check that it all functions. Each year you will
have it checked again to see that it is roadworthy. You wouldn’t
just take a picture of it . After a few years the mechanic might
say, “ it still looks good, but the oil pump is showing a really
low pressure, and is about to blow…you must stop driving this car
“.
In neuropsychology the doctor would
be telling the boxer ” you look good, but the test results are beginning
to fall off, you need to stop now” Neuropsychology is a dynamic
assessment of the brain in action, not just a static two-dimensional
picture.
Brain scans show the damage once
it is done, and beyond repair. Neuropsychology will hopefully give
us plenty of warning that things are beginning to go wrong, allowing
us as doctors to advise boxers when to stop. It will help us to
stop boxers getting hurt, rather than the scan, which will just
show us when the hurt has been done.
The use of these tests is still
a little way off. Some studies are already up and running to look
at which are the best tests to use. In years to come, if all goes
according to plan, each boxer will have a quick 20-minute test repeated
every year. This will help us, the doctors, to help you the boxer.
It isn’t just another test to annoy you; it will be done for sound
reasons so that we can really look out for, and look after you.
