INTRODUCTION
Most
doctors who treat patients suffering from bipolar depression, as well as the
patients themselves, would probably agree that it is a condition that is
challenging to treat in a fully effective manner. Although an increasing number
of pharmaceutical compounds to address depressions and to stabilize moods are
becoming available, these are not always fully satisfactory for many patients.
Many bipolars, for example, find that medications that are available can lead to
significant side effects, and therefore find themselves having to choose between
living with these unpleasant effects or discontinuing medications (or decreasing
dosages) and somehow learning to manage despite severe mood swings. Others find
that despite an exhaustive trial-and-error process involving different
combinations of drugs, their mood swings continue to present major problems for
them. Finally, many bipolar women who want to have children face the option of
either undergoing extremely difficult mood swings while pregnant or taking a
risk that their children will suffer birth defects, since all of the available
mood stabilizers are known or suspected to be harmful to developing fetuses in
human populations.
This summary of information about alternative
medicine is designed to help to address these problems by giving bipolars an
additional tool they can use to control their illness. In some cases, such
alternative methods may work in a complementary way to the use of conventional
medications, helping them to work better or, in some cases, to lower necessary
dosages. In other cases, alternative treatments may be effective on their own,
allowing some people to gradually taper off of their existing medications or (in
cases where current mood stabilizers are deemed unacceptable by the patient and
doctor because of health complications) may help to lessen mood swings to the
point where patients can lead more normal and satisfying lives.
Alternative methods to the management of bipolar
disorder tend to work in one or more of three different ways. First, some
therapies seem to work in a similar fashion to pharmaceuticals, but with fewer
side effects, in the direct management of moods. For example, acupuncture seems
to be fairly effective at controlling mania for many people over the short-term,
while the herb St. Johns Wort seems to have activity as an anti-depressant.
Second, some alternative methods look for alternate
explanations for what psychiatrists may have labeled as manic-depression. For
example, food allergies may cause severe mood swings in some people, and
untreated endocrine problems of all sorts are widely recognized as causing mood
difficulties.
Third, some treatments attempt to improve the overall
health of the individual, under the theory that this will allow the body to more
effectively fight off mood problems (especially depressions). Such theories
suggest that when an individual's health becomes taxed, the "weakest
link" is the one that is likely to snap. For some people, this means that
high blood pressure of heart problems will occur; for others, that cancer will
form; and for still others, that mood problems will result. It is generally
recognized that periods of emotional or physical stress tend to worsen mood
disorders (especially depressions) in many manic-depressives, for example, and
that learning to deal better with stress (perhaps through psychotherapy) and
proper nutritional and exercise habits may to some extent help to keep the
disease under control. Many alternative practitioners recommend going a step
farther, however, and suggest that some other kinds of more active methods (such
as those described below) may provide additional help.
With a few exceptions, most of the alternative
methods described below tend to address depressions or the short-term mood
fluctuations suffered by "rapid-cyclers" (and generally treated by
most knowledgeable doctors with anticonvulsants) rather than the more
"classic," longer-term highs and lows that are usually treated with
lithium. Many alternative practitioners, in fact, state that despite their best
efforts, lithium is still a necessity for some patients, although they may tend
to attempt to minimize the necessary dosage through a variety of other means.
Most alternative practitioners, however, seem to believe that the need for the
long-term use of antidepressants by bipolar or unipolar depressives can usually
be eliminated through the use of alternative treatments, although it may take a
substantial amount of work before this can be accomplished. The use of anti-convulsants
such as Depakote and Tegretol seems to fall somewhere in the middle of the two
extremes: although the use of alternative methods may help many patients to
taper off of these medications, some need to continue to use at least small
dosages in order to remain stable. (It should be noted that since most
antidepressants increase rapid-cycling in many patients, the elimination of the
antidepressants may make these drugs less necessary.) In many cases, however,
decreasing the dosage of anti-manic agents is almost as desirable as eliminating
the need for medications entirely, since side effects tend to be substantially
less at smaller dosages for most patients.
Most of the therapies listed below tend to be
relatively safe and have few side effects for most people. Nevertheless, a few
points should be kept in mind. First, the patient's doctor should be kept aware
of the types of alternative treatments that are being used, and should closely
monitor any positive or negative effects that might occur as well as any
attempts to decrease the dosages of any medications that are being used.
Manic-depression is a serious illness that may have fatal consequences if
inadequately treated, and psychiatric medications may have severe side effects
if they are discontinued too abruptly or not kept in balance with one another.
In general, most psychiatrists (especially ones that specialize in medications,
who are preferable for bipolars since their medications are often difficult to
manage) are not very well-versed in alternative methods of treating bipolar
disorder and may put up some resistance or need to be supplied with relevant
information before they will render an opinion. In general, if a practitioner
strongly objects to a particular treatment for a particular reason, then it may
make sense to look into other methods instead. On the other hand, if a doctor
objects to all non-drug approaches, then the patient may have to take a stand
that he or she wants to try some of these approaches anyway, or may need to find
another doctor, if alternative methods are to be pursued.
Let me reiterate that I am not a medical practitioner
myself; however, I have done extensive reading on the topic and have attempted
to summarize the information on a variety of alternative treatments that is
widely available or that has been published in medical journals. However, I
strongly encourage you to use this information only as a starting point, and to
read more about the methods that you are interested in pursuing and/or to seek
out appropriate specialists.
In general, although alternative therapies can be
helpful, they do seem to require a substantial commitment on the part of the
individual---they are not nearly as convenient as simply taking a few pills
every day. In addition, using alternative techniques can be quite expensive,
since most insurance companies do not cover such treatments as acupuncture,
nutritional supplements or even food allergy testing. Still, for people who find
conventional medications to be insufficient or unacceptable for one reason or
another, the availability of alternative medications can be potentially useful
and therefore worth pursuing.
Alternative Approaches to the
Treatment of Manic-Depression
GENERAL
BOOKS
Following
are some books that discuss a variety of natural approaches to treating mood
disorders. References of more specific books dealing with particular types of
treatments are listed under the appropriate sections.
 | "Optimal
Wellness," Ralph Golan, M.D., Ballantine Books, New York, 1995. A
wonderful book that discusses a variety of conditions (including most of
those discussed below) that can lead to suboptimal health. For those who
want just one book on the topic of alternative approaches to health
(including mental health), this would be a good choice.
|
 | "The
Good News About Depression," Mark S. Gold, M.D., Bantam Books, New York,
1993. Not a "holistic medicine" book per se, but discusses a
variety of alternative diagnoses to depression and manic-depression
(including hormonal problems, nutritional deficiencies and environmental
toxicity) that the author believes should be ruled out before proceeding
with pharmaceutical treatment.
|
The
next four books deal specifically with issues related to alternative treatments
of depression and manic-depression, and provide roughly the same kinds of
information. Any of them would be a good choice.
 | "Beyond
Prozac," Michael J. Norden, M.D., HarperCollins, New York, 1995.
|
 | "Dealing
with Depression Naturally," Syd Baumel, Keats Publishing, New Canaan,
CT, 1995.
|
 | "Depression
and Natural Medicine," Rita Elkins, Woodland Publishing, Pleasant
Grove, Utah, 1995.
|
 | "Natural
Alternatives to Prozac," Michael T. Murray, N. D., William Morrow and
Company, New York, 1996.
|
In
addition, readers may be interested in looking at some books dealing with the
topic of chronic fatigue, since bipolar disorder often has many of the same
symptoms and responds well to the same kinds of approaches as chronic fatigue:
 | "The
Canary and Chronic Fatigue," by Majid Ali, M.D., Life Span Press,
Denville, NJ, 1994. Although written in a somewhat haphazard manner, this is
a substantive book dealing with the topic in a relatively innovative manner
by a respected physician and associate professor of pathology at Columbia
University.
|
 | "From
Fatigued to Fantastic," by Jacob Teitelbaum, M.D., Avery Publishing Group, Garden City
Park, N. Y., 1996. Although the title sounds like a bit of an overstatement,
this book cover the common alternative treatments for Chronic Fatigue
Syndrome in a readable and common-sense manner. Includes references and
protocols to share for the benefit of physicians treating the problem.
|
 | "The Downhill Syndrome,"
by Pavel Yutsis, M. D. and Morton Walker, M. D., Avery Publishing, Garden
City Park, N. Y., 1997. Another fairly good book on the topic of Chronic
Fatigue Syndrome.
|
 | "Chronic
Fatigue Syndrome: The Hidden Epidemic," Jesse A. Stoff, M. D. and Charles R
Pellegrino, Ph.D., Harper Perennial, 1992.
|
 | "Chronic
Fatigue Syndrome and the Yeast Connection,"
William G. Crook, M.D., Professional Books, Jackson, Tennessee, 1992.

Alternative
Treatments III- NUTRITIONAL APPROACHES
NUTRITIONAL
APPROACHES
A
wide variety of vitamins, minerals and amino acids are related to the
maintenance of a normal mood; deficiencies of any of these can present problems.
Advocates of nutritional approaches to the treatment of mood disorders give
several reasons why supplementation may be appropriate. First, most Americans do
not eat ideal diets (for instance, they tend to consume substantial quantities
of processed foods and empty calories such as sugar, white flour and alcohol,
and often neglect to eat certain important food groups entirely), meaning that
they may be deficient in even the Recommended Daily Allowances (RDAs) for many
nutritional compounds. In addition, many people believe that the RDAs for many
substances are designed only to protect the individual from life-threatening
disease (e.g. scurvy, beri-beri, etc.), and that more subtle physical
dysfunction (such as mood problems) may occur as a result of deficiencies even
when the RDAs are achieved. Finally, some evidence suggests that certain people,
such as those inclined toward mood disorders, require greater-than-normal
amounts of some nutritional substances for optimal functioning, either because
they do not easily absorb certain compounds, or because their abnormal
metabolisms make higher amounts necessary.
Nutritional substances such as herbs may be useful
not because they are inherently required by the body, but because they exhibit
pharmacological actions that can suppress the symptoms of depression and/or help
the body to repair itself. The action of such substances should be considered
similar to that of prescription medications used to treat mood disorders;
however, natural substances of this sort usually cause far fewer side effects
than do most prescribed drugs.
Those interested in exploring a nutritionally based
approach to the management of mood disorders should be aware that most
physicians (including psychiatrists) tend to be relatively ignorant and
skeptical about the efficacy of this course of action. This is probably the case
because most physicians tend to receive little training in nutrition (most
medical schools devote, at most, only an hour or two of lecture time in a
broader class to the topic), and because less controlled research has been done
on the efficacy and safety of nutritional substances than on pharmaceuticals
(primarily because drug companies have no incentive to research such substances
since they cannot be patented, advocates of a nutritionally based approach
argue). Nevertheless, an increasing number of books, many written by
well-credentialed physicians, covering this topic are available, as listed
below.
Following is a summary of some various nutritional
substances that have been shown or reputed to be useful in the management of
mood disorders such as depression or manic-depression:
Mood-Stabilizing
Compounds
Relatively
few substances are said to have the ability to control mood swings directly in
the manner that prescription mood-stabilizers do. In addition, it may be the
case that those substances that have been identified may be more useful in
controlling rapid-cycling (which tends to be addressed with anticonvulsants by
psychopharmacologists) than in the longer, more "traditional" swings
that are often successfully addressed through the use of lithium. For this
reason, lithium (itself a natural substance and probably required by the body in
trace quantities) is often recommended by those people favoring a nutritional
approach to mood disorders; however, alternative practitioners seem to be more
likely to recommend the lowest possible dosage of this substance (often
substantially lower than those prescribed by many psychiatrists), supplemented
with other measures.
Other than lithium, substances that may have
mood-stabilizing effects include the following:
1. Phosphatidyl Choline (Lecithin)
A fairly convincing number of studies suggest that this substance has
significant effects on the manic-depressive, with some claiming that it
stabilizes moods while others suggesting that it serves as a mood depressant. It
is probable that it actually has both actions (as does the prescription drug
Depakote). For that reason, although lecithin may be useful in helping to
stabilize moods, it should probably be used cautiously, with the patient
starting at a fairly low dosage (perhaps 2 capsules of a 35% concentration of
the substance per day) and then increasing gradually until moods are stabilized
or mild depression is encountered. The recommended amount of this substance for
this use seems to vary widely---some people suggest that relatively small
amounts (perhaps 3-12 capsules per day) can be quite effective, while others
suggest that only much greater amounts tend to be fully effective. (More
concentrated forms of this substance are available but not usually stocked in
health food stores.) Even if lecithin is only partially successful in reducing
mood swings, however, this may still be helpful for those who want to reduce
their dosages of prescription medications (for instance, because of side effects
at higher amounts) or for those who suffer less severe mood swings. Most writers
seem to recommend splitting up the dosages of lecithin over the course of the
day (2-3 times per day), or taking the full dosage at night, although there do
not seem to be any studies addressing this issue.
2.
L-Taurine
Taurine is an amino acid that has been shown to have anti-convulsant
qualities, and appears to be potentially helpful for both epileptics and those
suffering from manic-depression (especially the rapid-cycling form). The usual
recommended dosage seems to be 500-1000 mg, 1-3 times per day, although there
seems to be no experimental or anecdotal evidence that larger dosages can cause
any unwanted side effects. As with all amino acids, pharmaceutical quality
product in capsules is preferable, despite the higher cost----capsules tend to
be absorbed more easily, and lesser-quality forms may have the potential of
being subject to contamination (such as that which occurred with tryptophan
several years ago). Divided dosages are probably preferable.
3. GABA
GABA is usually classified as amino acid, although it actually serves as a
neurotransmitter (there are more GABA sites in the brain than for any of the
other neurotransmitters such as dopamine or serotonin). GABA basically serves as
an inhibitory transmitter, keeping the brain and body from going into
"overdrive." Currently, for instance, pharmaceutical companies are
working on a GABA Reuptake Inhibitor that would artificially keep more GABA in
the synapses of the brain (similar to what Prozac and related drugs do for
serotonin) as a treatment for anxiety). Supplementation of GABA seems to be
quite effective for anxiety disorders as well as insomnia (especially the type
of insomnia where racing thoughts keep the individual from falling asleep). In
addition, although there has been little if any research reported on this, there
is also reason to believe that GABA may be effective in the treatment of
manic-depression, since many of the substances that are currently used for this
purpose (including Depakote and, obviously, gaba-pentin) affect GABA usage.
Those who want to experiment with the usage of GABA for anxiety or
manic-depression should start at a low dosage (perhaps 250 mg at bedtime or when
anxiety occurs) and observe their reactions before taking a larger amount. This
may be especially important for those people taking mood stabilizers that may
affect GABA usage, since the interaction between the two may cause an
undesirable overreaction to occur (just as those who are taking serotonin-based
drugs such as Prozac should be careful about taking serotonin's precursor,
tryptophan). Undesirable effects of too much GABA may include tingling or
numbness in extremities or trunk of the body and shortness of breath; if this
occurs, take a smaller amount in the future.
Other
Nutrients Related to Mood
1.
B Complex
The B vitamins are important factors in determining mood; deficiencies of any
or all of these vitamins can produce significant symptoms relating to
depression, anxiety, irritability, lethargy and fatigue. Many bipolars state
that supplementation of B vitamins is extremely important to helping them to
feel better. In general, B vitamins tend to work best together as a group;
taking too much of any of them may result in deficiencies of others and,
therefore, unwanted symptoms. B complex tends to be sold in B50 (50 mg of most
of these vitamins, 50 mcg of a few, and 400 or 800 mcg of folic acid) or B100
(100 mg/mcg) dosages; bipolars may find relief with as little as 1 B50 or as
many as 6 B100s per day. As with many other supplements, capsule form may be
preferable although it is more expensive (some people say manic-depressives do
not absorb this vitamin complex easily), and divided dosages also may be
preferred. Although other factors (such as some medications) may interfere, a
dark yellow-orange urine color may suggest that the individual is taking a
sufficient quantity of this vitamin complex.
2. B1 (Thiamin)
Although B vitamins are usually best taken as a group, there are certain
circumstances when larger amounts of a particular vitamin may be useful. Thiamin
deficiencies tend to produce the following clusterof symptoms, frequently
reported by the manic-depressive: chronic fatigue, irritability, memory loss,
personality changes (such as aggression), insomnia, anxiety, restlessness, night
terrors, appetite loss, sensitivity to noise, numbness and tingling in hands and
feet, and circulation problems. Supplementation is usually 100 to 500 mg of this
vitamin per day, in addition to the B complex.
3. B6 (Pyridoxine/Pyridoxal-5-Phosphate)
Deficiency of this vitamin can cause irritability, which is expressed by many
manic-depressives. Those women who suffer from PMS, birth-control-pill-induced
irritability, and post-partum depression often have deficiencies of this
vitamin. In addition to the irritability quotient, there are several ways to
detect deficiencies for this substance. a) Try the following test: Extend your
hand, palm up, then try to bend the two joints in your fingers (not the knuckles
of your hand), until your fingertips reach your palm. (This is not a fist, only
two joints are bent.) Do this with both hands. If it is difficult, if finger
joints don't allow tips to reach your palms, a pyridoxine deficiency is likely.
b) Have yourself tested for pyroluria. This is a condition where an
above-average amount of a substance called "kryptopyroles" circulate
in the body. The substance is harmless in itself; however, it tends to attach
itself to both B6 and zinc and to pull these substances out of the body through
the urine, causing deficiencies of both. Most doctors are unaware of this test,
but if you insist they will be able to order it from Norsom Medical
Laboratories, 7243 West Wilson Avenue, Harwood Heights, IL, 60656, (708)
867-9709 . c) Deficiency of B6 causes motion sickness; if you tend toward this
malady, you may be more confident that you have a deficiency of this vitamin.
Supplementation of B6 is a bit tricky, since high dosages over long periods of
time may result in numbness of fingers and (especially) toes and (if extremely
high dosages of several thousand milligrams per day are used for an extended
period of time) permanent nerve damage. Precautions include: a) Don't take B6 by
itself; include an at least somewhat proportional amount of B complex. Some
people think that it is not the excess B6 itself that causes problems, but
rather the deficiency of the other vitamins that excess amounts leads to. b) Use
the more bioavailable pyridoxal-5-phosphate form. c) Don't take amounts in
excess of what is necessary to control symptoms. d) If symptoms of tingling or
numbness in the toes or fingers results, reduce the dosage immediately.
Recommended amounts of pyridoxal-5-phosphate (in addition to that obtained from
a B complex) range from as little as 10 mg per day to as much as 250 mg; 50 mg
is probably sufficient for most people. (If regular B6 is used, the amounts used
are generally 50-500 mg, with 100 mg as an acceptable amount for many people.)
4. B12
B12 is a vitamin necessary for energy production; a deficiency of it can
cause fatigue, anemia and lack of coordination. B12 is a vitamin that is
difficult to absorb through the digestive system; in particular, older people
(whose digestive systems are less efficient than younger ones) are often
deficient in this vitamins. In addition, since this vitamin is present mostly in
meats, vegetarians are often deficient. In general, the sublingual or nasal
forms of this vitamin are preferred (B12 shots are also available through
physicians); between 500 to 2000 mcg per day is generally thought to be an
appropriate amount for supplementation. In extreme circumstances, doctors can
also give shots of several thousand mcg. (No adverse side effects to even very
large amounts seem to have been reported.)
5. Folic Acid
Folic acid is a vitamin that has recently received significant attention in
the media for its importance in preventing spinal malformations in fetuses.
Manic-depressives, however, need to be careful about taking high dosages
(probably in excess of 3000 mcg per day), since anecdotal evidence has suggested
that this may lead to manic behavior. Large dosages of folic acid also reduces
the efficiency of anticonvulsants such as Depakote for epileptics and (probably)
manic-depressives. Finally, as most people are aware, the use of drugs such as
Depakote can lead to spinal malformations in fetuses. All of this suggests that
folic acid seems to act in a way that is opposite from Depakote or other
anticonvulsants, and therefore should usually be avoided except in the amounts
present in foods or B complex. (Vitamin pills are allowed, by decree of the FDA,
to include no more than 800 mcg of folic acid, so unless a substantial number of
these are taken per day, this probably shouldn't be a problem.) An exception is
when the patient has a demonstrated deficiency of folic acid (observable through
blood tests), either spontaneous or caused through the use of anticonvulsants or
other drugs; in this case, supplementation to bring the vitamin to the normal
blood level may be used.
6. Magnesium and Calcium
A majority of Americans do not consume the RDA of magnesium. This is
problematic since magnesium deficiency may lead to various problems such as
anxiety, insomnia (especially that which consists of waking up in the middle of
the night and being unable to go back to sleep), fatigue (as experienced in
chronic fatigue syndrome), fibromyalgia, high blood pressure or PMS.
Supplementation of this mineral is therefore desired for most people, especially
those with mood problems. Magnesium is usually supplemented concurrently with
calcium, since the two work together and since absorption tends to be greater
when they are taken together. (Calcium may also act to relax the individual.)
The usual recommendation is 2 parts calcium to 1 part magnesium---for example,
1000 mg of calcium and 500 mg of magnesium---taken at bedtime; however, a higher
ratio of magnesium may be used to control PMS or similar conditions. Calcium
carbonate is the most easily obtained form of calcium but is the lest
digestible; many people (especially older individuals) will obtain better
results through the use of other forms such as amino acid chelates, calcium
citrate or hydroxapatite.
7. Manganese
Manganese is a trace mineral that, in deficiency, can produce fatigue,
irritability, memory problems and (most specific for diagnosis) ear noises such
as ringing.
8. Zinc
An deficiency in zinc can contribute to mental problems, and is especially
common among people who suffer from pyroluria (see the section on B6 above).
Deficiencies of this mineral are common, since it's hard to get enough zinc from
the typical American diet (unless oysters are regularly consumed). Recent
studies suggest that zinc supplementation is especially important during
pregnancy. Generally, supplementation of no more than 30 mg is recommended
unless a diagnosis of pyroluria has been made through lab tests.
9. L-Tyrosine
L-tyrosine is an amino acid that serves as a precursor to the
neurotransmitters norepinephrine and dopamine, which have been shown to be
deficient in many manic-depressives during their depressed cycles. The
supplementation of this amino acid may help the body to form more of these
substances during these difficult times; in addition, it may be helpful in cases
when clinical or subclinical thyroid disease is present. General recommendations
are usually 500-5,000 mg per day, on an empty stomach in the morning or early
afternoon (start at a low level and then work up gradually). As with all amino
acids, try to get pharmaceutical grade product in capsules.
10.
L-Phenylalynine and DL-Phenylalynine
Phenylalynine is a precursor to tyrosine, and so exhibits many of the same
effects. In addition, the supplementation of phenylalynine can help the body to
produce a substance called "phenylethylamine," which has been shown to
be deficient in many manic-depressives. (Phenylethylamine is also present in
chocolate and marijuana, and is created by the body in greater amounts when the
individual is "in love"; conversely, a deficiency such as that
suffered by many manic-depressives may lead to an unhappy feeling similar to
that which "normal" people feel when they are heartbroken.)
Phenylethylamine is supposedly present to a greater degree in the DL form of
phenylalynine than the L form; however, the DL form may be more likely to
increase blood pressure. (The issue of blood pressure increases is often cited
as a problem for both the DL and L forms. This increase should be no more than
10 points for an hour or two after the substance is consumed; however, those
people who are inclined toward high blood pressure should monitor theirs
carefully and decrease or discontinue their use of this substance if a problem
is observed.) The usual recommendation for the COMBINATION of tyrosine and
phenylalynine (DL or L) is 500 to 5,000 mg per day, on an empty stomach in the
morning or early afternoon. It is generally recommended that users start with a
low dose and work up gradually.
11. Methionine
Methionine is an amino acid that has been shown to be helpful for some
individuals suffering from depression. (Its metabolite, SAM, has also been used
to treat depression in some countries, but is not currently available in the
United States.) A reasonable dosage seems to be 500-2000 mg per day.
12.
L-Tryptophan and 5-Hydroxy-Tryptophan
L-tryptophan is an amino acid that serves as a precursor to the
neurotransmitter serotonin (the one that is affected by SSRI drugs such as
Prozac, Zoloft and the like). L-tryptophan was quite popular in treating
depression and insomnia during the 1980s; however, in 1990 the substance was
deemed responsible for a number of deaths and pulled from the market in the
United States. Although the deaths were later attributed to a contamination of
the product (non-pharmaceutical grade) made by one particular manufacturer, L-Tryptophan
is currently available primarily by prescription in the United States, although
this may change in the near future. (Some retailers have been known to sell
veterinary versions of the amino acid for human use, however; one problem with
this is that animal-grade amino acids may not be of the highest quality.) One
phamacy that sells l-Tryptophan by prescription is Belmar, 1-800-525-943. It is
also available over-the-counter in some European countries such as Holland.
However, another related product,
5-hydroxy-tryptophan, is currently available over the counter. 5-HTP is a
metabolite of tryptophan (that is made in the body) that may work even better
than tryptophan, so it may be worth a try for people who suffer from depression,
irritability or other symptoms
