The Centers for Disease Control and Prevention (CDC) estimates that eight percent of the adolescent and adult population have depression. Depression is a mood disorder that causes continual feelings of sadness, hopelessness and helplessness. Symptoms include insomnia, irritability, concentration difficulties and loss of interest in normal activities. Here are six common triggers for depression.

Negative Cognitive Patterns
People with depression tend to have illogical, negative thought patterns that exacerbate depression. For example, one might dwell on their failures, exaggerate minor problems or have a pessimistic view of life. As a result, the negative self-talk and depression form a vicious cycle. Cognitive behavioral therapy (CBT) is an effective way of treating unhelpful thought patterns.

Trauma
Depression triggers also come in the form of past and present traumatic experiences. For example, a life changing accident or the anniversary of a death of a loved one may trigger depression. Individuals suffering from PSTD may also experience depression when exposed to situations similar to the traumatizing event.

Major Life Event
Certain major life events can cause a depressive episode. This includes events that occur at work, school and at home. For example, being fired or failure to get a job promotion at work. Divorce and dropping out of school are also primary causes of depression.

Financial Difficulties
Chronic money problems will increase daily worries and create relationship stress. Credit card debt, constant bills and a home mortgage all cause intense stress and hopelessness. This is especially true if the person lacks the financial resources to seek problem mental health care treatment.

Failing to Follow Treatment
People with depression, who are on a treatment plan, may relapse if they fail to follow their treatment plan. This can include anything from forgetting to take medication or missing a therapeutic session. Since the symptoms of depression can be overwhelming, it is important follow the treatment plan.

Isolated Aging
According to the National Institute of Mental Health (NIMH), depression often occurs among older adults. While there are contributing hereditary factors, older adults experience depression because of social isolation and health problems. Depression tends to occur with other medical conditions among older adults, such as diabetes, cancer, dementia and chronic pain.

There are many different triggers for depression. These include negative thought patterns, traumatic experiences and major life events. Financial difficulties and failing to properly follow treatment for depression are also triggers. Isolated, older adults in need of constant medical attention will benefit from hospice care centers like Cornerstone Hospice and Palliative Care to help them through their periods of depression.
