Attention
deficit-hyperactivity disorder (ADD or ADHD) is defined as a condition in which
a child has an inability to concentrate , shows disruptive behavior, lack of
concentration and sometimes excessive physical activity.
ADHD
often goes undiagnosed if not caught at an early age, and it affects many
adults who may not know of their condition.
What
are the symptoms of ADHD?
ADHD
is generally recognized by
·
A
pattern of inattention
·
Distractibility
·
impulsivity
and hyperactivity
·
Learning
disabilities or emotional problems are often seen in ADHD
·
Children
with ADHD experience an inability to sit still and pay attention in class
·
They
often engage in disruptive behavior
Dietary
changes
The
two most studied dietary approaches to ADHD are the Feingold diet and a hypoallergenic
diet.
The
Feingold diet
Benjamin Feingold, M. D developed this diet, on the idea that salicylates
(chemicals similar to aspirin that are found in a wide variety of foods) are an
underlying cause of hyperactivity. In some studies, this hypothesis does not
appear to hold up.
However,
in studies where markedly different levels of salicylates were
investigated , a causative role for salicylates could be detected in some
hyperactive children. According to a study 10 to 25% of children may be sensitive to
salicylates. Parents of ADHD children can contact local Feingold Associations
for more information about which foods and medicines contain salicylates.
The
Feingold diet also eliminates synthetic additives, dyes, and chemicals, which
are commonly added to processed foods. The yellow dye tartrazine has
been specifically shown to provoke symptoms in controlled studies of
ADHD-affected children. Again, not every child reacts, but enough do so that a
trial avoidance may be worthwhile.
The
Feingold diet is complex and requires guidance from either the Feingold
Association or a healthcare professional familiar with the Feingold diet.
Hypoallergenic
Diet
The
Hypoallergenic Diet is a clinically designed program to help you identify the
food triggers of chronic disease. The Hypoallergenic Diet is also known as the
elimination diet.
The
diet uses food elimination and re-introduction to identify foods that can cause
disease symptoms in sensitive individuals.
In
one study, children diagnosed with ADHD were put on a hypoallergenic diet,
and those children who improved (about one-third) were then challenged with
food additives.
All
of them experienced an aggravation of symptoms when given these additives.
Other studies have shown that eliminating individual allergenic foods and
additives from the diet can help children with attention problems.
Some
parents believe that consuming sugar may aggravate ADHD. One study found that
avoiding sugar reduced aggressiveness and restlessness in hyperactive children.
Lifestyle
changes
Smoking
during pregnancy should be avoided , as it appears to increase the risk of
giving birth to a child who develops ADHD.
Lead
and other heavy-metal exposures have been linked to ADHD. If other therapies do
not seem to help a child with ADHD, the possibility of heavy-metal
exposure can be explored with a health practitioner.
Nutritional
supplements
Magnesium
Some
children with ADHD have lowered levels of magnesium. In a preliminary, controlled
trial, children with ADHD and low magnesium levels were given 200 mg of magnesium
per day for six months. Compared with other magnesium-deficient ADHD children,
those given magnesium supplementation had a significant decrease in hyperactive
behavior.
L-Carnitine
In
a double-blind study, supplementation with L-Carnitine for eight weeks resulted
in clinical improvement in 54% of a group of boys with ADHD, compared with a
13% response rate in the placebo group. The amount of L-Carnitine used in this
study was 100 mg per 2.2 pounds of body weight per day, with a maximum of 4
grams per day. No adverse effects were seen , although one child developed an
unpleasant body odor while taking L-Carnitine. Researchers have found that this
uncommon side effect of L-Carnitine can be prevented by supplementing with
riboflavin. Although no serious side effects were seen in this study, the
safety of long-term L-Carnitine supplementation in children has not been well
studied . This treatment should, therefore, be monitored by a physician.
Essential
Fatty Acids
Vitamin
B
B
vitamins, particularly vitamin B6, have also been used for ADHD. Deficient
levels of vitamin B6 have been detected in some ADHD patients. In a study of
six children with low blood levels of the neurotransmitter (chemical messenger)
serotonin, vitamin B6 supplementation (15–30 mg per 2.2 pounds of body weight
per day) was found to be more effective than methylphenidate. However, lower
amounts of vitamin B6 were not beneficial. The effective amount of vitamin B6
in this study was extremely large and could potentially cause nerve damage, although
none occurred in this study. A practitioner knowledgeable in nutrition must be
consulted when using high amounts of vitamin B6. High amounts of other B
vitamins have shown mixed results in relieving ADHD symptoms.
