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.

Relapse From Antidepressant Medication May Be Lack Of Response To Medication In The First Place
|
August 16, 2007
A new study by Rhode Island Hospital researchers indicates that a relapse during antidepressant continuation treatment may be due to a relapse in patients who were not true drug responders. The loss of drug response may be due to loss of placebo response (a positive medical response to taking a placebo as if it were an active medication.).
Historically, the treatment of depression is divided into three phases -- initial/acute, continuation and maintenance. During the initial phase, the goal is to reduce symptoms and psychosocial impairment. During the continuation phase, usually six months to one year after initial treatment response, the goal is to maintain the gains and prevent a relapse. In the maintenance phase, which occurs after a sustained period of improvement, the goal is to further maintain the gains and prevent recurrence of the disorder.
Mark Zimmerman, MD, director of outpatient psychiatry at Rhode Island Hospital and associate professor of psychiatry and human behavior at the Warren Alpert School of Medicine at Brown University, is the paper's lead author. Zimmerman, along with his colleague Tavi Thongy, MD, also of Rhode Island Hospital and Brown University, conducted a meta-analysis of continuation studies of new generation antidepressants that began as placebo-controlled acute phase studies. Treatment studies of depression have found that approximately 50 to 65 percent of patients respond to medication and that approximately 25 to 35 percent respond to placebo.
Past studies have indicated that a number of patients who respond to treatment in the initial phase experience a relapse or recurrence despite ongoing pharmacotherapy during the two latter phases of treatment. This return of symptoms is often interpreted as a loss of efficacy of antidepressant activity, and is referred to as tachyphylaxis or the "poop-out" effect.
Zimmerman says, "When a patient improves after being prescribed an antidepressant medication you do not know if they got better because of the medication or because they had a placebo response."
The researchers used formulas developed by Quitkin and colleagues more than a decade ago to calculate the relapse rate attributable to relapse in presumptive placebo responders. "Our study suggests that the return of symptoms despite ongoing treatment during the continuation and maintenance phases of treatment may not represent a loss of drug effect because the patient may not have experienced a true drug response in the first place."
Zimmerman also notes, "While our conclusion is limited to the continuation phase of treatment, our results suggest that these findings probably also apply to the maintenance phase of treatment."
The researchers note that these findings are not inconsistent with conclusions that continuation and maintenance studies of antidepressants have clearly established the benefit of ongoing treatment beyond the acute phase.
The study was published in the August issue of the Journal of Clinical Psychiatry.

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.
