Learn More About Depression
What is depression?
Depression is a serious mental health disorder that affects the whole body including mood and thoughts. It touches every part of one’s life.
It is important to know that depression is not a weakness or character flaw—it is a chemical imbalance in the brain that needs to be treated.
If you have one episode of depression, you are at risk of having more throughout life. Without treatment, depression can happen more often and become more serious.
Scientists believe that depression doesn’t have a singular cause, but may be brought on by a traumatic event, changes in life circumstances, genetics, changes in the brain, or alcohol or drug addiction.
Anyone can feel sad or depressed at times. However, depression is more intense and harder to manage than normal feelings of sadness. A person may have different symptoms of depression including:
- Ongoing sad, anxious, or “empty” mood
- Feeling hopeless or helpless
- Having low self-esteem
- Feeling inadequate or worthless
- Excessive guilt
- Repeating thoughts of death or suicide, wishing to die, or attempting suicide (Note: people with these symptoms should get help right away)
- Loss of interest in usual activities or activities that were once enjoyed, including sex
- Relationship problems
- Trouble sleeping or sleeping too much
- Changes in appetite and/or weight
- Decreased energy
- Trouble concentrating
- A decrease in the ability to make decisions
Left untreated, depression can be a debilitating illness for individuals and their families. Often, symptoms are not recognized for their severity and can worsen, and severe depression may lead to suicidal thoughts and actions.
Common treatments for depression include individual and group therapy, and medications as appropriate.
Other treatments may include TMS (transcranial magnetic stimulation), ECT (electroconvulsive therapy), or ketamine, which have been found to have profound effects on individuals with depression, especially for those who have not found relief in symptoms through other treatment methods.
Many factors contribute to depression, and it is likely caused by an imbalance of brain chemicals. Life events (such as stressful life changes) may also contribute to a depressed mood. Depression also tends to run in families. The exact biological cause of depression is still being investigated, including by scientists at McLean like Diego A. Pizzagalli, PhD.
Suicidal behavior is defined as a preoccupation or act that is focused on causing one’s own death voluntarily.
- Suicidal ideation refers to thoughts of suicide or wanting to take one’s own life
- Suicidal behavior refers to actions taken by one who is considering or preparing to cause his or her own death
- Suicide attempt usually refers to an act focused on causing one’s own death that is unsuccessful in causing death
- Suicide refers to having intentionally caused one’s own death
Talking about suicide is the best way to prevent it. Although it is not possible to predict suicide with any certainty, our best tool is recognition of the signs that many people exhibit when contemplating suicide.
These three behaviors should prompt you to seek immediate help for you or a loved one:
- Talking about wanting to die or to kill oneself
- Looking for a way to kill oneself, such as searching online or obtaining a gun
- Talking about feeling hopeless or having no reason to live
