Depression, in plain language.
Depression is a medical condition with patterns clinicians can recognize and treatments that have been studied for decades. This site explains it the way a psychiatrist would explain it to a patient, without the noise. Written and reviewed by Shariq Refai, MD, MBA, a board-certified psychiatrist with 15 years of clinical experience.
If you're in immediate danger or thinking about ending your life, call or text 988 in the United States, or call 911. The Suicide and Crisis page lists more options.
People come to a page like this for different reasons. Some are trying to put words to what they're feeling. Some are reading on behalf of a partner, a child, a parent, or a friend. Some have already been in treatment and want a refresher in plain language. This site is built for all of those readers.
Depression is common, treatable, and often misunderstood. About 8 percent of U.S. adults experience a major depressive episode in any given year, according to the National Institute of Mental Health, and roughly one in five will at some point in their lives. It isn't a character flaw and it isn't a personality. It's a medical condition with patterns that clinicians can recognize, and with treatments studied for decades in trials reviewed by organizations such as the World Health Organization and the American Psychiatric Association. What follows is a starting point, not a substitute for an evaluation.
Most people picture depression as sadness or crying. In a clinic, the picture is usually wider. Energy drops. Sleep changes in one direction or the other, and food either loses its appeal or becomes a way to numb. Small decisions feel heavy. Things that used to be enjoyable, a show, a meal, a walk, lose their color. Thoughts slow down, or speed up into self-criticism.

Depression isn't one thing. Major depressive disorder is the form most people recognize, but there's also persistent depressive disorder, seasonal depression, postpartum depression, bipolar depression, depression after grief, depression that comes with a medical illness, and depression that travels alongside anxiety.
The Types of Depression section explains each one in plain language and notes how clinicians tell them apart.
There's no single right treatment for depression. Most people do best with a combination, often some form of psychotherapy along with attention to sleep, movement, and structure, and in many cases a medication trial under a clinician. Severe or treatment-resistant depression has more options than it used to, and a careful psychiatric evaluation is usually the first step.
The Treatment page walks through what an evaluation looks like, what therapies have evidence behind them, how antidepressants are used, and what questions to bring to a clinician.

When depression becomes urgent
Some signs need same-day attention. Thoughts of suicide with a plan or intent, sudden calm after a long period of distress, giving away possessions, gathering means, severe self-neglect, psychosis, mania, or any threat to self or others. If any of these are present, call 988, call 911, or go to the nearest emergency department.
