I have to say this forum has the most caring people, plus it's truly the best format I've ever seen for a forum. Very easy to navigate. The personal assistant is excellent. There's even games like tetris which can really take your mind off of negativity. I hope the chat gets fixed. smile.gif

Depression & Mental Health FAQs
US Centers for Disease Control and Prevention (CDC) estimated 40 million Americans living today will suffer from major depressive illness during their lives. Seasonal affective disorder is major depression that appears in the fall or winter and goes away in spring, thought to be caused by lack of sunlight.
Postpartum depression occurs within four weeks of a women giving childbirth. Most new mothers suffer from some form of the �baby blues.� Postpartum depression, by contrast, is major depression, thought to be triggered by changes in hormonal flows associated with childbirth. Catatonic depression is a rare form of major depression characterized by (at least two): Stupor, excessive motor activity, extreme negativism, peculiarities in voluntary movement, and repetition of other people's words or actions. - mcmanweb.com
Psychotic depression is a rare form of depression characterized by delusions or hallucinations, such as believing you are someone you are not and hearing voices.
According to the National Institute of Mental Health, approximately 18.8 million American adults, or about 9.5 percent of the US population age 18 and older in a given year, have a depressive disorder. Depression is a chronic illness that exacts a significant toll on
America's health and productivity. It affects more than 21 million
American children and adults annually and is the leading cause of
disability in the United States for individuals ages 15 to 44.
Lost productive time among U.S. workers due to depression is estimated
to be in excess of $31 billion per year. Depression frequently
co-occurs with a variety of medical illnesses such as heart disease,
cancer, and chronic pain and is associated with poorer health status
and prognosis. It is also the principal cause of the 30,000 suicides
in the U.S. each year. In 2004, suicide was the 11 th leading cause of death in the United States, third among individuals 15-24.
According to the World Health Organization, depression is presently on track to becoming the world's second-most disabling disease (after heart disease) by the year 2020. Depression is responsible for some $87 billion a year in lost productivity in the US (a conservative estimate), and according to Bank One, is responsible for most lost work days in its employees after pregnancy and childbirth. Additionally, one million people worldwide die by their own hand, most as a result of a mood disorder. Finally, the linkage between depression and a host of physical illnesses makes it arguably the world's greatest killer.
Research presented at the 56th Annual Conference of the Canadian
Psychiatric Association shows a marked link between bipolar disorder
and migraines. The odds of migraine in persons with bipolar disorder were 40% higher than the general population. Data
obtained from 36,984 people aged 15 and over, who screened positive for
manic or depressive episodes with migraine, were compared against those
who screened positive for mania but who didn�t suffer from migraines. Amongst
males, 14.9% of those with manic episodes were also diagnosed with
migraines compared with 5.8% of the general population. Amongst
females, 34.7% had both migraines and bipolar disorder compared with
14.7% who only had migraines.unquote.gif While the research was
skewed towards persons who were already diagnosed with bipolar
disorders, what does it mean for people who suffer from migraines but
who may have an undiagnosed bipolar disorder?
Migraines and headaches aren�t fully understood but the manifestations are very real and debilitating for their sufferers: Throbbing pain Nausea Heightened sensitivity to light or sound Seeing dots, wavy lines, flashing lights, or blind spots Difficulty with speech, sensation, or movement
An estimated 2.1 million
American adolescents have experienced major depression within the last
year, according to a new comprehensive government study. Researchers
surveyed more than 67,000 young people ages 12 to 17 and found that one
in 12 had suffered from serious depression in the previous year.Nearly
13 percent of girls had struggled with depression, compared to less
than 5 percent of boys. Odds of depression increased with age -- just 4
percent of 12-year-olds experienced depression but that climbed to 11
percent for older teens.

Gene Implicated In Bipolar Disorder

Gene Controlling Circadian Rhythms Implicated In Bipolar Disorder
Science Daily — Disrupt the gene that regulates the biological clocks in mice and they become manic, exhibiting behaviors similar to humans with bipolar disorder.

Scientists from UT Southwestern Medical Center show that the Clock gene, which controls the body's circadian rhythms, may be integrally involved in the development of bipolar disorder. Circadian rhythms include the daily ups-and-downs of waking, eating and other processes such as body temperature, hormone levels, blood pressure and heart activity.
"There's evidence suggesting that circadian genes may be involved in bipolar disorder," said Dr. Colleen McClung, assistant professor of psychiatry and the study's senior author. "What we've done is taken earlier findings a step further by engineering a mutant mouse model displaying an overall profile that is strikingly similar to human mania, which will give us the opportunity to study why people develop mania or bipolar disorder and how they can be treated."
Bipolar disorder, also known as manic-depressive illness, is a brain disorder that causes dramatic shifts in a person's mood, energy and ability to function -- much more severe than the normal ups and downs that most people experience. About 5.7 million American adults, or about 2.6 percent of the adult population, suffer from the psychiatric disorder.
The study included putting the mutant mice through a series of tests, during which they displayed hyperactivity, decreased sleep, decreased anxiety levels, a greater willingness to engage in "risky" activities, lower levels of depression-like behavior and increased sensitivity to the rewarding effects of substances such as cocaine and sugar.
"These behaviors correlate with the sense of euphoria and mania that bipolar patients experience," said Dr. McClung. "In addition, there is a very high co-morbidity between drug usage and bipolar disorder, especially when patients are in the manic state."
During the study, lithium was given to the mutant mice. Lithium, a mood-stabilizing medication, is most commonly used in humans to treat bipolar patients. Once treated with the drug on a regular basis, the majority of the study's mice reverted back to normal behavioral patterns, as do humans.
The researchers also injected a functional Clock gene protein -- basically giving the mice their Clock gene back -- into a specific region of the brain that controls reward functions and where dopamine cells are located. Dopamine is a neurotransmitter associated with the "pleasure system" of the brain and is released by naturally rewarding experiences such as food, sex and the use of certain drugs. This also resulted in the mice going back to normal behaviors.
"While the Clock gene is expressed throughout the brain, it's really only been studied in one particular brain region, which is the one that's involved in circadian rhythms," said Dr. McClung. "This is one of the first studies to show that Clock has a major effect on behavior in a different brain region -- specifically the one that controls reward responses and mood."
Dr. Eric Nestler, chairman of UT Southwestern's psychiatry department and also a study author, said the research is important because it establishes the first complete mouse model for studying bipolar disorder. "The lack of an animal model for bipolar disorder has been a crucial limitation in our efforts to better understand the biological basis of the disorder," said Dr. Nestler, who holds the Lou and Ellen McGinley Distinguished Chair in Psychiatric Research. "Dr. McClung's findings are therefore very important for the field and provide fundamentally new directions for one day developing improved treatments."
Other researchers from UT Southwestern's psychiatry department contributing to the study were: Dr. Shari Birnbaum, assistant professor; Dr. Sumana Chakravarty, assistant instructor; Dr. Scott Russo, postdoctoral research fellow; research technicians Ami Graham, Joseph Peevey and Kole Roybal; and Vaishnav Krishnan, MSTP student. Researchers from Harvard University, the Veterans Affairs North Texas Health Care System, Northwestern University and Howard Hughes Medical Institute also contributed.
The study was supported by grants from the National Institute on Drug Abuse and the National Institute of Mental Health, and is available online in the Proceedings of the National Academy of Sciences.

Depression & Mental Health FAQs 2
What is Clinical Depression? Clinical
depression can affect your body, mood, thoughts, and behavior. It can
change your eating habits, how you feel and think about things, your
ability to work and study, and how you interact with people. Clinical
depression is not a passing mood, a sign of personal weakness or a
condition that can be willed away. Clinically depressed people cannot
"pull themselves together" and get better. Depression can be
successfully treated by a mental health professional or certain health
care providers. With the right treatment, 80 percent of those who seek
help get better. And many people begin to feel better in just a few
weeks.
