|What causes ADD ?
|Question Date: 2004-12-10|
Unfortunately, doctors/scientists do not really
have an answer to your question yet. The symptoms
of ADD have become well recognized and
described (inattention, lack of focus, sometimes
hyperactivity), but researchers are still not sure
of the exact cause. At the moment, most research
suggests some neurobiological reason -->
meaning, the chemicals and nerves in the brains
of people with ADD, behave a little differently
than in non-ADD people.
ADD may be genetic because some families seem
to have a high number of ADD people.
Some people have suggested that diet and family
environment may lead to ADD, but most research
indicates that these causes are unlikely.
The good news is that ADD is now widely
recognized, so people who have it can get the
medical and phsychological help they need to lead
normal and productive lives.
There are many hypothesis as to what
causes Attention Deficit Disorder (ADD).
The most prominent is that ADD is genetic.
That is, if one of your parents has it, then you
are at a 25% chance to have ADD.
Another hypothesis is that multimedia such as
television, internet, and video games are involved
with ADD. The idea behind this hypothesis is that
these different forms of stimulation inundate the
brain and result in a short attention to one media
channel. You can image switching your attention
from instant messaging to email to television, you
get the picture.
Fundamentally, behavior elicited by ADD has
something to do with changes in the brain.
I read a recent study that mentions some
shampoos as being implicated risks for pregnant
women. Shampoo and other preservatives are said to
cause nerve cells not to grow correctly, which
causes neurological disorders.
Nobody knows for sure what causes ADD, or even
how to accurately diagnose this condition. ADD
is probably caused by a chemical imbalance in the
brain--either too much or not enough of some
specific chemical, possibly a neurotransmitter. We
don't know for sure, though, and it's very
difficult to test for some of these brain
Some researchers want to split the
condition into two different ones: ADD and ADHD
(attention deficit hyperactive disorder),
because some people with ADD are also hyperactive
but some are not. Since many other conditions,
like sleep disorders and depression, can have
symptoms just like ADD, many people get
mis-diagnosed. And since we don't know for
sure what causes the condition, treating it is
difficult. Different treatments work
differently in different people--even people who
definitely have ADD, not some other condition.
