“The term “nervous breakdown” is used by some people to describe a stressful situation when life’s demands become physically and emotionally overwhelming. It affects a person’s ability to meet their own needs and do daily tasks and activities. The term was often used in the past, but mental health professionals no longer use it. Instead, you may hear the term “mental health crisis””.4

Bipolar Disorder

Is bipolar disorder the same as depression?

DotS bipolar disorder may be described as a type of depression, however bipolar disorder is not the same as depression the serious illness or clinical depression. In Bipolar Disorder: What Is Bipolar Disorder? the NIMH’s definition is:

“Bipolar disorder (formerly called manic-depressive illness or manic depression) is a mental illness that causes clear shifts in a person’s mood, energy, activity levels, and concentration. People with bipolar disorder often experience periods of extremely “up,” elated, irritable, or energized behavior (known as manic episodes) and very “down,” sad, indifferent, or hopeless periods (known as depressive episodes)”.5

Mild, Moderate or Severe

How can depression be categorised?

In Depressive Disorder (Depression): Symptoms and Patterns the World Health Organization (WHO) explain:

“A depressive episode can be categorised as mild, moderate, or severe depending on the number and severity of symptoms, as well as the impact on the individual’s functioning”.6

Symptoms

What may be symptoms of depression?

Depression“Symptoms of depression are ongoing and affect your day-to-day life. They can include:

  • Feeling sad or “empty”
  • Losing interest in favorite activities
  • Overeating, or not wanting to eat at all
  • Sleeping too much, or not enough
  • Feeling very tired
  • Feeling hopeless, irritable, anxious, or guilty
  • Having aches and pains, headaches, cramps, or digestive problems
  • Having thoughts of death or suicide
  • Changing moods or behaviors
  • Increasing use of alcohol or drugs
  • Isolating from family and friends”.7

Cause

What may cause depression?

The WHO explain:

“Depression results from a complex interaction of social, psychological, and biological factors. People who have gone through adverse life events (unemployment, bereavement, traumatic events) are more likely to develop depression. Depression can, in turn, lead to more stress and dysfunction and worsen the affected person’s life situation and the depression itself.

Depression is closely related to and affected by physical health. Many of the factors that influence depression (such as physical inactivity or harmful use of alcohol) are also known risk factors for diseases such as cardiovascular disease, cancer, diabetes and respiratory diseases. In turn, people with these diseases may also find themselves experiencing depression due to the difficulties associated with managing their condition”.8

Common or Not

How common is depression?

Globally, according to statistics quoted by the WHO:

  • “Depression is a common mental disorder.
  • Globally, an estimated 5% of adults suffer from depression”.9

In the United States according to statistics quoted by the Anxiety and Depression Association of America (ADAA) in What Is Depression? Did You Know?:

“264 million people worldwide live with depression.

  • In 2017, around 17.3 million adults age 18 or older in the U.S. had experienced at least one major depressive episode in the last year (6.7% of adults in the U.S.)”.10

In England in Depression, the (United Kingdom) Mental Health Foundation note:

“In England, 3 in every 100 people will experience depression in any given week. Even more – 8 in every 100 – will experience mixed depression and anxiety”.11

Premenstrual Dysphoric Disorder

Is premenstrual dysphoric disorder (PMDD) a type of depression?

In What Are Anxiety and Depression: What Is Depression? Types of Depression the ADAA elaborate on:

Premenstrual dysphoric disorder (PMDD) is another manifestation of depression which is a severe and sometimes disabling extension of premenstrual syndrome (PMS). Although regular PMS and PMDD both have physical and emotional symptoms, the mood changes in PMDD are much more severe and can disrupt social, occupational, and other important areas of functioning”.12

Anxiety

Is there an association between anxiety and depression?

In What Are Anxiety and Depression: What Is Depression? Depression and Anxiety Disorders: Not the Same the ADAA explain:

“Depression and anxiety disorders are different, but people with depression often experience symptoms similar to those of an anxiety disorder, such as nervousness, irritability, and problems sleeping and concentrating. But each disorder has its own causes and its own emotional and behavioral symptoms.

Many people who develop depression have a history of an anxiety disorder earlier in life. There is no evidence one disorder causes the other, but there is clear evidence that many people suffer from both disorders”.13

Menopause

Is there an association between menopause and depression?

In Mood and the Menopause, content updated 09 February 2023, the Australasian Menopause Society elaborate on:

“Risk factors for depressive symptoms/disorders are multiple and include VMS, previous mood disorders including prior MDD, reproductive related mood disturbance (severe premenstrual syndrome (PMS) or postpartum depression), other health factors, psychological and socioeconomic factors, and hormonal changes such as variability in FSH and oestradiol”.14

What is MDD?

MDD can be an abbreviation for Major Depressive Disorder.

In In Depression In Women: 4 Things To Know – 4. You Can Get Help for Depression the NIMH also include:

“There is no “one-size-fits-all” for treatment. It may take trial and error to find the best one for you. A health care provider can explain the different options and help you choose the best treatment based on your symptoms. With help, you can feel better”.16

Health Care Provider

What if I think I have depression?

If you think you have depression, it may be in your best interest to choose to talk to your health care provider about this urgently.

In Depression In Women: 4 Things To Know – 1. Depression Is A Medical Condition the NIMH explain:

“Depression is not brought on by anything a woman has or has not done, and it is not something she can “snap out” of. Most women need treatment to feel better”.17

In Find A Mental Health Professional: What Are Mental Health Professional Services? Finding the Right Professional for You the (Australian) Beyondblue note:

“It’s important to find someone you feel comfortable with. While some people find a practitioner and treatment that works for them first time, for others it can take a few tries. The main thing is to persevere – try not to let one bad experience put you off getting support”.18
