Depression is psychologically rooted in loss. Some losses are tangible, like losing friends, family members, or a job. Others are internal, like losing a sense of direction or self-regard. Self-esteem injuries are one of the most common causes of depression. Feeling rejected or abandoned is another. Some depressions reflects an anger turned inward. When this is the case, a person become self-attacking, self-critical, and sometimes self-destructive.
Although often due to external events, sometimes depression doesn't appear connected to anything going on in a person's life. This is called endogenous depression, which is believed to be biological, and might be especially responsive to medication. Some people have a more persistent, chronic depression, called dysthymia, which is tied to personality. Another type of depression, agitated depression, describes a condition in which a person is depressed, but also paradoxically activated. They are irritable, restless, unable to sleep, sometimes with racing thoughts. This is a dangerous state to be in because it increases impulsivity and can lead a person to act on self-destructive thoughts.
How common is depression?
In the past year, 8 to 9 percent of US adults had a diagnosable depression. It is especially prevalent in emerging adults. Up to 21 percent of the population becomes depressed at some point in their lives.
Depression run in families. Research indicates 50 percent of the likelihood of developing depression is due to genetics. If you have a parent or sibling with depression, you're 2 to 3 times more likely to develop it yourself.
Psychodynamic therapy, cognitive-behavioral therapy (CBT), interpersonal psychotherapy (IPT), and acceptance and commitment therapy (ACT) are about equally effective in treating depression. Research indicates mindfulness-based cognitive therapy (MBCT) might be especially helpful for recurring depression.
There are many medications for depression, including SSRIs, SNRIs, and atypical antidepressants like Wellbutrin. Sometimes medications like Abilify are prescribed alongside an antidepressant to augment its effectiveness.
Research indicates combining psychotherapy and medication can yield the most benefit.
Transcranial magnetic stimulation (TMS) is a newer treatment, with minimal risks or side effects. Electroconvulsive therapy (ECT) is very effective, especially for agitated depression or depression with psychotic features.
Exercise improves depression. Research indicates it's probably as effective as medication for mild to moderate depression.
When people have vegetative symptoms, like trouble sleeping, loss of appetite, or psychomotor slowing, medication might be especially helpful.
When depression is chronic, like in dysthymia, and looks to be personality-based, psychotherapy is the treatment of choice.
