ADHD drugs: Are they the answer?
drugs usually fall within three classes of medication;
the stimulants, the
Recent research has concluded that ADHD drugs are now having some
effectiveness in controlling ADHD symptoms, The use of these
ADHD drugs have been founded on virtual chance discoveries of their
effectiveness, and as of yet have not been developed according to
any theoretical rationale. However, continuing research is emerging
which is defining recent theoretical models, emphasizing behavioral
inhibition as being a central aspect of the nature of this disorder.
Some level of control of this behavioral inhibition seems to be
current focus on the use of ADHD drugs.
ADHD drugs and the
neurological research indicate that there are brain regions which
subserve certain inhibitions which may be involved in the cause or
ADHD, and that ADHD drugs such as the stimulants seem to produce
their greatest effects within these brain regions. Until recently,
it was not clear precisely how these medications affected brain
functioning, and more specifically what their sites and
neurochemical modes of actions may be. It now appears as if the
major therapuetic effects of these ADHD drugs are achieved through
alterations in the frontal-striatal activity of the brain. Their
biochemical impact is believed to be centered on at least three or
more neurotransmitters important to the functioning of this part of
the brain which are related to response inhibition: dopamine,
norepinephrine, epinephrine, and perhaps even the neurotransmitter
How do these ADHD
The direct rationale
for employing these ADHD drugs, may be that they directly effect if
only temporarily, the deficiencies in these neural systems related
to behavioral inhibition and self-regulation.
