Examples of depression in the following topics:
-
- Major depressive disorder (also called major depression and clinical depression) is a mood disorder characterized by a pervasive and persistent low mood that is accompanied by low self-esteem and by a loss of interest or pleasure in normally enjoyable activities.
- Each year about 6.7% of U.S. adults experience major depressive disorder.
- People with persistent depressive disorder are chronically sad and melancholy but do not meet all the criteria for major depression.
- However, episodes of full-blown major depressive disorder can occur during persistent depressive disorder (APA, 2013).
- Children with DMDD are at risk for depression in later childhood or adolescence.
-
-
- When most people think of mood disorders, they typically think of depression (also called major depressive disorder and clinical depression) and bipolar disorder.
- While insomnia affects at least 80% of depressed people, hypersomnia, or oversleeping, can also happen.
- Dysthymia and major depression naturally have many symptoms in common, including depressed mood, disturbed sleep, low energy, and poor concentration.
- Cognitive-behavioral therapy has been shown to be a possible treatment for depression.
- Bipolar disorder is characterized by cycles of depressive and manic episodes.
-
- Depressants cause the body to relax by increasing the neurotransmitter GABA, which decreases neuronal excitability.
- A depressant (also called a central depressant) is a chemical compound that manipulates neurotransmission levels, thereby reducing arousal or stimulation in various parts of the brain.
- Depressants are widely used throughout the world as prescription medicines and as illicit substances.
- Depressants inhibit the next neuron from sending impulses by binding to receptor molecules.

-
- The Great Depression was a severe worldwide economic depression in the decade preceding World War II.
- It was the longest, most widespread, and deepest depression of the 20th century.
- In the 21st century, the Great Depression is commonly used as an example of how far the world's economy can decline.
- In many countries, the negative effects of the Great Depression lasted until the end of World War II.
- USA annual real GDP from 1910 to 1960, with the years of the Great Depression (1929–1939) highlighted.

- Two symptoms of depression are particularly salient in the context of physical health: lack of motivation and fatigue.
- Depressed patients are often physically sedentary, which can cause a reduction in physical work capacity.
- Another common symptom of depression is increased appetite and weight gain.
- Additionally, physical activity releases endorphins which can help combat mild depressive symptoms physiologically.
- Running is frequently recommended as therapy for people with clinical depression and people coping with addiction.
-
- Schizophrenia and depression are just two examples of mental illnesses caused by a disorder of the nervous system.
- A more detailed discussion of two mental illnesses, schizophrenia and major depression, is given below.
- Major depression (also referred to as just "depression" or "major depressive disorder") affects approximately 6.7 percent of the adults in the United States each year and is one of the most common mental disorders.
- The exact causes of major depression are unknown and probably include both genetic and environmental risk factors.
- Treatments for depression include psychotherapy, electroconvulsive therapy, deep-brain stimulation, and prescription medications.
-
- Freezing point depression is a colligative property observed in solutions, brought on by the introduction of solute molecules to a solvent.
- Freezing point depression is the phenomena that describes why adding a solute to a solvent results in the lowering of the freezing point of the solvent.
- The freezing point depression can also be explained in terms of vapor pressure.
- In this equation, $\Delta T_f$ is the freezing point depression, Kf is the freezing point depression constant, and i is the van 't Hoff factor.
- The freezing point depression constant changes depending on the solvent, and the van 't Hoff factor accounts for the number of particles that a dissolving solute creates in solution.
-
- Seasonal affective disorder (SAD) is a mood disorder in which people experience depressive symptoms with a seasonal change.
- Seasonal affective disorder (SAD), also known as winter depression, winter blues, summer depression, summer blues, or seasonal depression, is a mood disorder in which people who have normal mental health throughout most of the year experience depressive symptoms in the winter summer, spring or autumn year after year.
- People who experience spring and summer depression show symptoms of classic depression including insomnia, anxiety, irritability, decreased appetite, weight loss, social withdrawal, decreased sex drive, and suicide.
- The symptoms of SAD mimic those of dysthymia or even major depressive disorder.
- At times, patients may not feel depressed, but rather lack energy to perform everyday activities.
-
- Bipolar disorder (commonly referred to as manic-depression) is a mood disorder characterized by periods of elevated mood and periods of depression.
- Both manic and depressive episodes are so intense that they interfere with everyday life.
- A major depressive episode persists for at least two weeks.
- Hypomania also tends to be reported less frequently than a distressing, crippling depression, and so people with bipolar II are often misdiagnosed with major depressive disorder.
- Children with DMDD are at risk for depression in later childhood and adolescence.
