| Depression, Bipolar Disorder
and Omega 3 |
More than 20 million children and adults in
the U.S. are affected by major depression or bipolar disorder,
and depression has been shown to be a leading cause of disability
worldwide. In recognition of the scope and burden of these
serious medical illnesses, The National Institute of Mental
Health, (NIMH), a U.S. Government Agency, launched a major
effort to assess our current knowledge and to plan a course
of research that will move the Nation ahead in answering unsolved
questions related to mood disorders. |

To accomplish the task of reviewing the science and
recommending how to spur scientific progress, NIMH convened nine
scientific workgroups in January 2001. The groups spanned the breadth
of the relevant science, from genetics to clinical trials and psychosocial
interventions, to research that examines the service system and
obstacles to care. The workgroups were comprised of nationally recognized
scientific experts, members of the National Advisory Mental Health
Council, representatives of consumer and advocacy groups, and NIMH
staff.
One of the experts writing and speaking on this subject
was Joseph R. Hibbeln, M.D. who wrote the following article on March
8, 2002 on Omega 3 and its emerging protective role as a potential
treatment for borderline personality disorders.
Emerging protective roles for omega-3 fatty
acids in affective and aggressive disorders. A potential treatment
for borderline personality disorders?
Recent data from epidemiological studies and placebo
controlled intervention trials in affective and aggressive disorders
suggest that omega-3 essential fatty acids may have a role in the
therapy of borderline personality disorder since these conditions
have several common features. Although the idea that the dietary
intake of polyunsaturated fatty acids could be efficacious in this
disorder may seem unusual, it should be pointed out that their importance
have already been widely recognized in major illnesses including
heart disease, cancers, rheumatoid arthritis and diabetes. Despite
the observation that the majority of the brain is comprised of lipids
and fatty acids, the examination of the role of lipids and fatty
acids in psychiatric disorders is still in its infancy. Of particular
interest are two polyunsaturated essential fatty acids: docosahexaenoic
acid (DHA) and arachidonic acid (AA), which are selectively concentrated
in synaptic neuronal membranes and thought to be necessary for optimal
neurodevelopment. These fatty acids, and their precursors, cannot
be made de novo and are available only from dietary sources such
as seafood, which is a rich source of DHA and other omega-3 fatty
acids such as eicosapentaenoic acid (EPA). Disorders with affective
and/or impulsive features appear to be responsive to greater omega-3
fatty acid intake. In cross-national analyses, greater seafood consumption
has been associated with lower prevalence rates of major depression
across a 50-fold range, lower prevalence rates of bipolar disorders
across a 30-fold range, and lower rates of homicide mortality across
a 20-fold range. Randomized, double-blind, placebo-controlled trials
of mixtures of DHA and EPA or of EPA alone have documented robust
responses in bipolar disorder, treatment resistant depression (two
trials) and in reducing measures of hostility and aggression. Since
patients with borderline personality disorder frequently have concurrent
affective and impulsive features, but respond poorly to most medications,
omega-3 fatty acids can be explored as a potential treatment alternative.

Signs and symptoms of depression (or a depressive
episode) include:
• Lasting sad, anxious, or empty mood •
Feelings of hopelessness or pessimism • Feelings of guilt,
worthlessness, or helplessness • Loss of interest or pleasure
in activities once enjoyed, including sex • Decreased energy,
a feeling of fatigue or of being "slowed down" •
Difficulty concentrating, remembering, making decisions •
Restlessness or irritability • Sleeping too much, or can't
sleep • Change in appetite and/or unintended weight loss or
gain • Chronic pain or other persistent bodily symptoms that
are not caused by physical illness or injury • Thoughts of
death or suicide, or suicide attempts
A depressive episode is diagnosed if 5 or more of
these symptoms last most of the day, nearly every day, for a period
of 2 weeks or longer.
Descriptions offered by people with bipolar disorder
give valuable insights into the various mood states associated with
the illness:
Depression: I doubt completely my
ability to do anything well. It seems as though my mind has slowed
down and burned out to the point of being virtually useless….
[I am] haunt[ed]… with the total, the desperate hopelessness
of it all…. Others say, "It's only temporary, it will
pass, you will get over it," but of course they haven't any
idea of how I feel, although they are certain they do. If I can't
feel, move, think or care, then what on earth is the point?
Hypomania: At first when I'm high,
it's tremendous… ideas are fast… like shooting stars
you follow until brighter ones appear…. All shyness disappears,
the right words and gestures are suddenly there… uninteresting
people, things become intensely interesting. Sensuality is pervasive,
the desire to seduce and be seduced is irresistible. Your marrow
is infused with unbelievable feelings of ease, power, well-being,
omnipotence, euphoria… you can do anything… but, somewhere
this changes. Mania: The fast ideas become too fast and there are
far too many… overwhelming confusion replaces clarity…
you stop keeping up with it—memory goes. Infectious humor
ceases to amuse. Your friends become frightened…. everything
is now against the grain… you are irritable, angry, frightened,
uncontrollable, and trapped.
TO SUM UP: Essential fatty acids
are critical components of synaptic membranes. Data suggesting
efficacy in Omega 3 treatment in numerous psychiatric disorders
has been emerging worldwide. Omega-3 fatty acids found
in fish oil are being studied to determine their usefulness, alone
and when added to conventional medications, for long-term treatment
of bipolar disorder.
