Signs & Symptoms of Depression

Understanding Depression

Learn About Depression

Everyone has periods of time in their lives when they experience feelings of sadness or hopelessness. These instances are especially common when someone experiences a major life stressor, such as losing a job or having to relocate to a new city. However, other individuals have a much stronger reaction to negative events in their life and instead of having a simple case of the blues, they struggle with debilitating depressive disorders that impact all areas of their life. Depressive disorders affect an individual’s mind, body, and thoughts leaving them to face tremendous emotional pain. The most common types of depressive disorders include:

Major depression includes a combination of symptoms that significantly disrupt a person’s ability to properly eat, sleep, work, have interpersonal relationships, or engage in activities once enjoyed. Major depressive disorder can become so debilitating that a person is unable to function normally in his or her daily life. While some people may only experience one episode of major depressive disorder in their lifetime, others may struggle with multiple cycles of depressive symptoms that come and go over time.

Minor depression is a milder form of depressive disorder that is defined by the presence of symptoms that are not severe enough to meet the criteria for major depression. While not as severe, the symptoms of mild depression can cause daily difficulties and impact one’s overall sense of well-being. Untreated minor depression should not be overlooked as it can lead to the development of major depression episodes during one’s lifespan.

Dysthymic disorder, or dysthymia, is a mental health disorder characterized by pervasive symptoms that cause an impediment in activities of daily living for two years or longer. Additionally, people who have dysthymia may experience episodes of major depressive disorder during their lifetime.

It’s important to recognize the severity of depressive disorders because if they are not properly treated, they can lead to extreme self-destructive behaviors, such as self-harm, suicidal thoughts and behaviors. However, most cases of depressive disorders are treatable using the right amount of medications, therapies, and proper self-care. Most individuals with a depressive disorder are able to overcome their depression and lead a happy, healthy, and productive life.

Causes and Risk Factors

Causes and Risk Factors for Depression

Depression is a serious mental illness that is thought to be caused by a combination of genetic, environmental, and physical risk factors working together. The most common causes and risk factors for depressive disorders include:

Genetic: Mental illnesses such as depression often run in families. People who have a first-degree relative who has struggled with depression are at a greater risk than others without a similar history for developing the disorder at some point in their lifetime. However, there are many cases of depression that occur in absence of familial history.

Physical: Neuroimaging studies conducted on the brains of those who have been diagnosed with depression show structural differences in the areas of the brain that are responsible for sleep, appetite, and behaviors. Additionally, decreased levels of certain types of neurotransmitters in the brain, including serotonin and dopamine, have been implicated in the development of depressive disorders.

Environmental: The stress and trauma associated with certain types of major life events may overwhelm a person’s ability to cope and can lead certain individuals who have other risk factors to develop depression.
