Depression and Mood Disorders

Depression

Depression is a type of mood disorder that involves the body, mood, and thoughts. It affects the way a person eats and sleeps, the way one thinks about things, and the way one feels about oneself. A depressive disorder is not a sign of weaknesses or simply a passing bad mood. Without treatment, depressive symptoms can last for weeks, months, or years. Appropriate treatment, however, can help most people who suffer from depression.
Depression can occur during adolescence, a time of great personal change. Teens may be facing changes in where they go to school, their friends, their after-school activities, as well as in their relationships with family members. These are all factors that can increase an adolescents risk for depression.

Black Dog video

It is important to remember that the Black Dog (i.e. Depression) can begin to grow in children and in teens. It's not just adults. When the Black Dog appears in children it becomes a "member" of the whole family. Luckily, as pointed, out there are effective treatments to help manage the depression, and even send it away on long holidays, and maybe even with children and teens, away for good.

    Even mildly insufficient sleep associated with increased risk for depresion and anxiety symptoms

    4/27/17
    Medscape reports that "Although past research has shown a link between severe sleep dysfunction and psychological symptoms, new research suggests that even mildly insufficient sleep duration can have an adverse effect. Examining data from a nationwide telephone survey of more than 20,000 adult participants, the investigators found that each hour of additional sleep was significantly linked to a decreased risk for symptoms of depression, hopelessness, nervousness, and feeling restless or fidgety."

    1 in 9 new mothers suffer from Postpartum Depression

    2/21/17
    Medscape reports that "Approximately one in nine women in the United States experience depressive symptoms after giving birth, according to a surveillance analysis published in the February 17, 2017 issue of Morbidity and Mortality Weekly Report. However, the proportion of mothers who experience postpartum depression has recently declined in some states. The overall prevalence of self-reported postpartum depressive symptoms (PDS) was 11.5% in 2012 for the 27 states included in the current analysis. Individual states showed wide variation, however, ranging from a low of 8.0% in Georgia to a high of 20.1% in Arkansas, according to data from the CDC Pregnancy Risk Assessment Monitoring System."

    1 in 10 preschoolers have suicidal thoughts. behaviors

    12/1/15
    Medscape reports that "About 1 in 10 children as young as age 3 years may have suicidal thoughts or suggestive behaviors, and these linger into middle childhood for 3 of 4 children, particularly for those with depression or externalizing disorders, new research suggests. Although the meaning of suicidal cognitions and behaviors at this young age remains unclear, the results suggest that they are a "clinically important phenomenon" that should not be ignored, investigators Diana J. Whalen, PhD, and colleagues write. "Our findings suggest that clinicians may need to start asking about suicidal thoughts and behaviors in young children, particularly among those with early-onset psychiatric disorders. While we do not know exactly what suicidal thoughts and behaviors mean in young children, they are likely a signal of distress and should be taken seriously," Dr Whalen told Medscape Medical News."

    Meta-analysis links low zinc level with depression

    1/6/14
    A new meta-analysis shows that individuals diagnosed with depression have less peripheral zinc in their bodies. In an interview with Medscape the authors note that ""A growing body of evidence demonstrates that experimental zinc deficiency can induce depressive-like behavior in animals, which can be effectively reversed by zinc supplementation," the authors write. Furthermore, preliminary clinical trials have suggested that zinc added to antidepressant therapy may produce more rapid or more effective improvement in depressive symptoms."

    PET Scan predicts whether therapy or meds will best lift depression

    12/22/13
    New research funded by the NIMH shows what the future might hold. In the study, pre-treatment scans of brain activity predicted whether depressed patients would best achieve remission with an antidepressant medication or psychotherapy. “Our goal is to develop reliable biomarkers that match an individual patient to the treatment option most likely to be successful, while also avoiding those that will be ineffective,” explained Helen Mayberg, M.D., of Emory University, Atlanta, a grantee of the NIH’s National Institute of Mental Health.

    Currently, determining whether a particular patient with depression would best respond to psychotherapy or medication is based on trial and error. In the absence of any objective guidance that could predict improvement, clinicians typically try a treatment that they, or the patient, prefer for a month or two to see if it works. Consequently, only about 40 percent of patients achieve remission following initial treatment. This is costly in terms of human suffering as well as health care spending.

    Using PET scans, the researchers found that "Activity in one specific brain area emerged as a pivotal predictor of outcomes from two standard forms of depression treatment: cognitive behavior therapy (CBT) or escitalopram, a serotonin specific reuptake inhibitor (SSRI) antidepressant. If a patient’s pre-treatment resting brain activity was low in the front part of an area called the insula, on the right side of the brain, it signaled a significantly higher likelihood of remission with CBT and a poor response to escitalopram. Conversely, hyperactivity in the insula predicted remission with escitalopram and a poor response to CBT."

    Oxytocin Dysfunction Seen in Both Depressed Moms and Kids

    11/24/13
    New research shows that a dysfunctional oxytocin system may underpin the long-term harmful effects of maternal depression on child development, suggesting a potential for oxytocin-based interventions, researchers say. This then leads to the possibility to therapies that help trigger the infant's oxytocin may help head off the negative effects of living with a depressed mother.

    Most teens who think about suicide do not receive mental health services

    4/10/13
    A new study founded by the NIMH find that "within the past year, 3.6 percent of adolescents had suicidal thoughts, but did not make a specific plan or suicide attempt. In addition, 0.6 percent reported having a plan, and 1.9 percent reported having made a suicide attempt within the past year. Suicidal behavior among youth was not only associated with major depression, but also with a range of other mental health problems including eating, anxiety, substance use and behavior disorders, as well as physical health problems. Between 50 and 75 percent of those teens who reported having suicidal ideation had recent contact with a service provider. However, most only had three or fewer visits, suggesting that treatment tends to be terminated prematurely. Moreover, most teens with suicidal ideation did not receive specialized mental health care.

    Research suggests how depression develops in the brain

    5/1/11
    New research funded by the NIMH. The NIMH news release states "Activating neurons in a brain structure linked to disappointment increased depression-like behaviors in rats, while suppressing the neurons' activity reduced the behaviors, according to an NIMH-funded study. The findings help to explain previous research linking this brain structure to depression in humans and highlight a cellular process that hadn't been previously explored in mood disorders research. The study was published in the February 24, 2011, issue of Nature.

    Current Depression Among Adults—United States, 2006 and 2008

    12/5/10
    New Research shows that in 2006 and 2008 9% of Adult Americans qualify for the diagnosis of depression. The prevalence of major depression increased with age, from 2.8% among persons aged 18–24 years to 4.6% among persons aged 45–64 years, but declined to 1.6% among those aged =65 years. Women were significantly more likely than men to report major depression (4.0% versus 2.7%), as were persons without health insurance coverage compared with those with coverage (5.9% versus 2.9%), persons previously married (6.6%) or never married (4.1%) compared with those currently married (2.2%), and persons unable to work (22.2%) or unemployed (9.8%) compared with homemakers and students (3.0%), persons employed (2.0%), and retired persons (1.6%).

    Resilience Factor Low in Depression, Protects Mice From Stress

    5/19/10
    Researchers have discovered a mechanism that helps to explain resilience to stress, vulnerability to depression, and how antidepressants work. The new findings, in the reward circuit of mouse and human brains, have spurred a high tech dragnet for compounds that boost the action of a key gene regulator there, called deltaFosB.
    DeltaFosB is a a transcription factor – inside neurons, and works to turn multiple genes on and off, triggering the production of proteins that perform a cell's activities. The researchers found that triggering deltaFosB in the reward circuit's hub is both necessary and sufficient for resilience. They found that it protected mice from developing a depression-like syndrome following chronic social stress. The researchers are now looking for ways to trigger the action of deltaFosB as a way to possibly treat depression.

    Rapid Antidepressant Action of Common Medication Confirmed by Repeat Trial

    5/15/10
    Confirming results from earlier research, a clinical trial of treatment for major depression showed that the medication scopolamine, commonly used for motion sickness and as a sedative, could lift symptoms of depression within days, far faster than current antidepressants. Though the study was small, the magnitude of scopolamine's effects in comparison with placebo suggests that this class of medications has potential for rapid treatment of depression.

    Whole Diet May Ward Off Depression and Anxiety

    1/6/09
    A new study finds that a traditional or whole diet characterized by vegetables, fruit, whole grains, and high-quality meat and fish may help prevent mental illness — specifically, depression and anxiety. Conversely, a Western diet high in refined or processed foods and saturated fats may increase the risk of depression, new research suggests. The research also points to the importance of Omega's in helping to prevent anxiety and depression. The authors note that high quality meat is hard to find in the United States because most cattle is raised in food lots where they are raised on corn. This makes them a very poor source for Omega 3's. In the Rochester area if you are looking for beef raised on grass the best local source is Heiden Farms. They sell meat at the Public Market.

Depression Treatment

    Metacognitive therapy shown effective for treatment of Depression in adults

    3/22/17
    Medscape reports that "Metacognitive therapy (MCT), a psychotherapeutic approach that targets persistent rumination and negative thought processes, has a large effect size when used to treat depression and may offer a viable alternative to mainstay cognitive-behavioral therapy (CBT), results from a new randomized control trial show. "The results of this trial of MCT for depression are encouraging with large and statistically significant reductions both for depressive and anxious symptoms following 10 sessions of treatment. These improvements were sustained at 6 months follow-up," the authors, led by Roger Hagen, PhD, Norwegian University of Science and Technology, Trondheim, Norway, write."

But the same effect has not been studied in children -- until now. Results from a new study are showing that children receive the same beneficial effect from being active. We're talking about moderate to vigorous physical activity that leaves kids sweaty or out of breath. Researchers at the Norwegian University of Science and Technology (NTNU) and NTNU Social Research have followed hundreds of children over four years to see if they could find a correlation between physical activity and symptoms of depression"

    Light Therapy an effective treatment for nonseasonal major depression

    11/27/15
    Medscape reports that "The combination of bright light therapy plus an antidepressant significantly improves nonseasonal major depressive disorder, and light therapy alone is more effective than antidepressant monotherapy, a randomized, placebo-controlled trial suggests. "I've studied bright light therapy in winter depression for a long time, but we always thought that winter depression was different from nonseasonal depression," Raymond Lam, MD, University of British Columbia, Vancouver, Canada, told Medscape Medical News. "So this was the first study that was placebo-controlled, and I think that while light therapy could be used on its own for some patients, more severely ill patients need combination therapy, whether that combination be an antidepressant plus psychotherapy or psychotherapy plus light therapy or light therapy plus an antidepressant.""

    Discontinue Antidepressants in Rapid-Cycling Bipolar Disorder

    6/24/15
    Medscape reports that "Discontinuing rather than maintaining antidepressant medications following treatment of depression in patients with rapid-cycling bipolar disorder (BD) appears to improve outcomes, new research shows. "In this sample, long-term continuation of antidepressants was associated with more mood episodes in patients with rapid-cycling bipolar disorder, particularly with three-fold increased rate of depressive episodes in the first year of follow-up," the investigators, led by Rif El-Mallakh, MD, Department of Psychiatry, University of Louisville, in Kentucky, write. "Any history of rapid cycling or antidepressant-induced mania is a very good predictor of doing poorly with long-term antidepressant treatment," Dr El-Mallakh told Medscape Medical News. "This population should be given nonantidepressant alternatives when they are depressed, or the antidepressants should be discontinued as soon as symptoms normalize."
