I have a friend who's child is having unexplained seizures. She is really watching her MSG intake. She was surprised to find how ubiquitous it is in food and beverage. It is something to consider as well as a food diary.
Good luck,
"My interest in ADD and ADHD arose from my studies on the process of
excitotoxicity. Excitotoxicity is a neurological phenomenon associated
with certain amino acids that produce a delayed degeneration of
particular neurons when exposure occurs outside the cell. This process
has been proposed as the central event in many neurological disorders,
including strokes, head injury, migraines, hypoglycemia,
ischemia/hypoxia as well as causing toxicity directly.
We know that several of these excitotoxins play a vital role in brain
development, primarily glutamate and aspartate. It must be appreciated
that glutamate is the most abundant neurotransmitter in the brain. But,
elaborate steps are taken to assure that extracellular concentrations of
this substance remain only for a very short time ( milliseconds) and in
very low concentrations.
During brain development, there are wide physiological fluctuation in
glutamate brain levels. This series of events plays a vital role in
brain development. Too much or too little glutamate can result in
abnormal development of the brain. For example, high concentration of
glutamate in utero can cause neuron death in special brain areas and
even abnormal formation of brain pathways. That is, the brain is mis-
wired. This can result in anything from mild learning difficulties to
severe neuroendocrine, behavioral and learning deficits. There is some
evidence, for example, that abnormally low concentrations of glutamate
at critical times can result in schizophrenia. Some neuroscientist are
suggesting that such conditions as ADD, ADHD and autism may be cause by
such glutamate abnormalities.
Clinically, we know that many such children will significantly improve
when taken off foods containing excitotoxins, such as MSG ( and its many
disguised forms) and aspartame. It appears that several
neurotransmitters are abnormally functioning in ADD, such as dopamine,
norepinephrine, serotonin, histamine, and acetylcholine.
Almost a decade ago, it was found that feeding pregnant animals MSG
produced a form of learning difficulty similar to ADD. The offspring had
normal simple learning but showed profound defects in complex learning.
In a followup study of these offspring, it was found that they had an
80% reduction in frontal lobe acetylcholine levels and a 50% reduction
in norepinephrine. The latter plays a vital role in attention and
ability to focus. We also know that dopamine plays a vital role in
performance and memory. Serotonin deficiency appears to play a vital
role in violent and antisocial behavior.
It is also of interest that a significant number of these children are
reactive hypoglycemics. We know that hypoglycemia not only precipitates
the release of glutamate in the brain, but that magnifies the toxic
effect of all excitotoxins. Unfortunately, many food have excitotoxins
added to them as taste enhancers.
The approach to this disorder requires first, the removal of all food
borne excitotoxins. This must be done as early as possible. The longer
and more intense the exposure the more likely permanent damage will
develop. Manipulating the various neurotransmitters by nutritional means
is the next step. This involves several avenues of approach. Each step
requires patience. Other methods, such as biofeedback, can be helpful
during this period. Remember, biofeedback can alter brain chemistry. We
still have much to learn about this disorder. You should also be aware
that every child is different.
Treatment has to be tailored to each individual case.
