In a study of an epidemiologic sample of 776 adolescents by Pine and associates, symptoms of majordepressioninadolescencestrongly predicted episodes of major depression in adulthood.

What Are The Signs And Symptoms

Major depression symptoms vary from person to person. To receive a diagnosis of major depressive disorder, some of these signs and symptoms must be present for at least two weeks. Anyone who has questions should consult their doctor.

  • Continued feelings of sadness, hopelessness, pessimism, emptiness
  • Fatigue, lack of energy
  • Insomnia or other sleep issues such as waking up very early or sleeping too much
  • Anxiety, irritability, restlessness

  • Forgetfulness
  • Trouble concentrating, thinking clearly, or making decisions
  • Vague aches and pains, such as headaches, joint pain, back pain, or digestive problems
  • Thoughts of death or suicide, or suicide attempts

Diagnosis Of A Depressive Episode

After taking the affected personââ¬â¢s medical history and performing a physical examination, a doctor or the mental health specialist to which the person is referred to, can diagnose a depressive episode based on the criteria set out in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition .

A major depressive episode is characterized by five or more of the following symptoms being present every day, or almost every day, for a minimum of two weeks:

  • Depressed mood for most of the day
  • Loss of interest or enjoyment in all or most activities
  • Significant unexplained weight loss or gain, or appetite changes
  • Sleep disturbances, including insomnia or sleeping too much
  • Restlessness or sluggishness
  • Tiredness or lack of energy
  • Feelings of worthlessness or excessive guilt
  • Difficulty thinking, concentrating or making decisions
  • Thoughts of death or suicide ââ¬â there may be suicide plans or suicide attempts

These symptoms should indicate a marked difference from the affected personââ¬â¢s previous functioning. For the diagnosis to be made, at least one of the symptoms needs to be depressed mood or loss of interest in most activities. It is also necessary for the symptoms to cause significant distress or impairment in social and job functioning.

If the symptoms are attributed to another mental health condition, the diagnosis and treatment may be different to that detailed here for a depressive episode.

Enhancing Healthcare Team Outcomes

An interdisciplinary approach is essential for the effective and successful treatment of MDD. Primary care physicians and psychiatrists, along with nurses, therapists, social workers, and case managers, form an integral part of these collaborated services. In the majority of cases, PCPs are the first providers to whom individuals with MDD present mostly with somatic complaints. Depression screening in primary care settings is very imperative. The regular screening of the patients using depression rating scales such as PHQ-9 can be very helpful in the early diagnosis and intervention, thus improving the overall outcome of MDD. Psychoeducation plays a significant role in improving patient compliance and medication adherence. Recent evidence also supports that lifestyle modification, including moderate exercises, can help to improve mild-to-moderate depression. Suicide screening at each psychiatric visit can be helpful to lower suicide incidence. Since patients with MDD are at increased risk of suicide, close monitoring, and follow up by mental health workers becomes necessary to ensure safety and compliance with mental health treatment. The involvement of families can further add to a better outcome of the overall mental health treatment. Meta-analyses of randomized trials have shown that depression outcomes are superior when using collaborative care as compared with usual care.

    Bipolar Disorder Depression Major Depressive Episodes And Mixed Episodes

    There is no corollary to a hypomanic episode for depression no short-term hypodepressive episode that can be diagnosed. There is a related condition known as Dysthymic Disorder or Dysthymia, which describes a long-lasting mild depression. Dysthymia cannot be diagnosed at the same time as bipolar disorder, however, because in order to qualify for a diagnosis of Dysthymia, you have to show evidence of consistently mild depressive symptoms occurring more days than not over a period of at least two years. The presence of manic or hypomanic episodes during the two year period would disqualify any dysthymic disorder diagnosis.

    What Causes Major Depressive Disorder Symptoms

    GWAS of Major Depressive Disorder and its Related Phenotypes / 978

    A single cause of major depression is as yet unknown nor could a single cause be identified in a particular depressed individual. However, research suggests that several genetic, environmental, biological and psychological factors can combine to cause depression, including an imbalance in brain chemistry or extreme changes in hormone levels during certain times like pregnancy or menopause.

    Additionally, there are other risk factors that have been shown to be linked to depression. Having one or more of these factors may, though not always, make a person more prone to major depressive disorder symptoms:

    • A personal or family history of depression or substance abuse
    • Going through a traumatic or stressful event, such as childhood trauma or current situations like the death of a loved one.
    • Certain personality traits like low self-esteem and pessimism
    • A history of other mental health conditions or eating disorders
    • Substance abuse
    • Severe, terminal, or chronic illness
    • Certain medications, including some antidepressants

    Major depressive disorder symptoms can begin at any age, but typically develops in adulthood. In children and adolescents, one prominent symptom of depression is irritability, rather than a low mood.

    What Does Mdd Look Like In Children

    As much as we hate thinking about kids experiencing MDD, the harsh truth is that around 5% of children and adolescents experience depression at any given time. The number may be much higher, since the symptoms arent always the ones parents expect and they may not seek help.

    Along with the usual signs, a depressed kid is likely to:

    • Be irritable, frustrated, angry, and on edge

    • Have frequent crying fits and temper tantrums

    • Being aloof and not having any interest in interacting with peers or classmates

    • Become super-sensitive to scolding or criticism

    • Complain of recurring tummy aches or headaches

    • Try to get out of going to school, after-school activities, and on playdates

    • See a decline in school performance

    • Experiment with vaping, smoking, or alcohol

    With Treatment How Long Does It Take To Overcome Depression

    When I started my treatment, I started with therapy alone, so things were slow going.

    However, once I got on antidepressants, I started to notice things moving in the right direction. The antidepressants brought me to a place that allowed me to focus better on my therapy treatment, so the two forms of treatment worked well together.

    While I still experience on and off symptoms of depression, I feel that after one year of treatment, my life is finally at a point where I am feeling more like a normal person. The feelings of sadness and hopelessness are significantly reduced, I am performing well at work again and I am able to enjoy my time with my friends.

    Risk Factors For Depression

    Depression is one of the most common mental health disorders in the United States. Depression can develop from biological, environmental, or psychological factors. Although depression can happen at any age, it is most likely to begin in adulthood. Depression may look different depending on the age of the individual experiencing it, but one risk factor for developing chronic mood or anxiety disorders as an adult begins with having high levels of anxiety as a child. Depression often co-occurs with other serious medical illnesses such as diabetes, cancer, Parkinsons disease, and heart disease. Depression can often make chronic medical conditions worse if left untreated. Other risk factors for depression may include:

    • History of depression in self or family members
    • Life events
    • Trauma
    • Medications, as depression could be a side effect
    • Motherhood or having a child
    • Substance use issues
    • Social isolation
    • Childhood abuse or neglect

    While genetic factors can play a crucial role in the development of depression, non-genetic factors can also be significant. Depression can be triggered through life events, even when those events seem generally positive. When a mix of genetic susceptibilities and overwhelming environmental factors combine, the more likely an individual is to develop major depressive disorder.

    Life Expectancy And The Risk Of Suicide

    7 Most Common Types of Depression

    Depressed individuals have a shorter life expectancy than those without depression, in part because people who are depressed are at risk of dying of suicide. Up to 60% of people who die of suicide have a mood disorder such as major depression, and the risk is especially high if a person has a marked sense of hopelessness or has both depression and borderline personality disorder. About 2â8% of adults with major depression die by suicide, and about 50% of people who die by suicide had depression or another mood disorder. The lifetime risk of suicide associated with a diagnosis of major depression in the US is estimated at 3.4%, which averages two highly disparate figures of almost 7% for men and 1% for women . The estimate is substantially lower than a previously accepted figure of 15%, which had been derived from older studies of people who were hospitalized.

    Depressed people have a higher rate of dying from other causes. There is a 1.5- to 2-fold increased risk of cardiovascular disease, independent of other known risk factors, and is itself linked directly or indirectly to risk factors such as smoking and obesity. People with major depression are less likely to follow medical recommendations for treating and preventing cardiovascular disorders, further increasing their risk of medical complications.Cardiologists may not recognize underlying depression that complicates a cardiovascular problem under their care.
