Problems
with memory are a very common problem for people who have experienced a
traumatic brain injury (TBI). A lot of
people think of memory as being “good or bad”, but it is a lot more complicated
then that. There are a couple different
types of memory I’m going to explain here.
To
start things off, I’d like to say that everybody has memory for taste and
smell. The majority of people know the
taste of sugar and the smell of a rose. More
importantly there are visual memory and hearing memory. Visual memory is what we see; it allows us to
remember where we have been, where you’ve put something, or what you’re
eating. Visual memory is stored in the
right hemisphere of the brain. We have a
special part in our brain for verbal or hearing memory. This is stored in the left hemisphere of the
brain. The hearing part helps a person remember what they have read because
things we’ve read translate into language.
Next,
I’d like to talk about immediate memory and short-term memory. Immediate memory doesn’t last to long. It
might last just for a couple minutes.
You use immediate memory when a school teacher tells you a math problem
and you have to remember it long enough to write it down immediately. When a person has a head injury their
immediate memory might not be affected, but most head injured people experience
problems with short-term memory.
Immediate memory is something that is quickly “spit back”, but
short-term memory is information remembered after 30 minutes. An example would
be if the teacher said the math problem and it wasn’t written down, then the
teacher asks if anybody remembered the math problem 30 minutes later. I would
have difficulties remembering it, as would most people with brain
injuries. Short-term memory is what affects
a lot of brain injured individuals.
The
last type of memory I’m going to talk about is long-term memory. Long-term memory is information that is
recalled after a day, a couple weeks, or even 15 years. Long-term memory is the least effected by
head injuries. In fact, a lot of people
with head injuries will say, I can tell you what important thing I did 15 years
ago, but I have trouble remembering what I just did 15 minutes ago.
Information
flows in through the middle of our brain and branches out like branches on a
tree. Before the information heads off
to the different areas of our brain, it is channeled and filtered by a
system. When the brain is injured, the
middle areas that information passes through get pressed on because of
swelling. The middle area of the brain is also resting on a bone in the
skull. Forward and backward movement of
the brain in an accident can cause the middle areas to be ripped or scraped.
What
can we do to help us remember stuff? It
helps to get organized. For example, always put money in the same place. This way the second you have to grab some
extra cash, you know right where to look. Another way which will help, and I do
it a lot, is to write things down. I
write down the groceries I need to buy throughout the week, this way when the
day comes that I do my grocery shopping, I have my entire list right at hand. I
do this because there is no way I could possibly remember it all.
