What are the 5 symptoms of major depressive disorder?

There is no official list of exactly five symptoms. Clinicians use nine recognized symptoms of major depressive disorder, and a diagnosis generally takes at least five of them, present most of the day, nearly every day, for two weeks or more. One of the five has to be depressed mood or a loss of interest or pleasure.

If you typed this question into a search bar, you are probably trying to make sense of something. Maybe you have felt flat for weeks and want to know if it "counts." Maybe you are watching someone you love pull away, and you want something to hold up against what you see.

Both are fair reasons to look. This guide goes through all nine symptoms in plain language, explains where the number five comes from, and shows what a next step can look like.

If you are thinking about suicide, or you are worried about someone's safety: call or text 988 (Suicide & Crisis Lifeline), or call the Georgia Crisis & Access Line at 1-800-715-4225. If you or someone you know is in immediate danger, call 911 or go to your nearest emergency room.

Where the "5 symptoms of major depressive disorder" come from#

Major depressive disorder (MDD) is a mood disorder defined by at least two weeks of low mood or lost interest, along with changes in sleep, energy, thinking, and daily functioning. The "5" people search for is a threshold. It was never a list.

The manual clinicians use, the DSM-5-TR, describes nine symptoms. To meet the criteria, a person has five or more of them during the same two-week period, and at least one is depressed mood or loss of interest or pleasure (American Psychiatric Association).

Two more conditions apply. The symptoms have to cause real distress or get in the way of work, school, relationships, or daily life. And they can't be better explained by a medical condition, a substance, or another mental health condition.

Depression is common. The National Institute of Mental Health estimates that about 21 million U.S. adults, roughly 8.3%, had at least one major depressive episode in 2021 (NIMH). If you recognize yourself in this article, you have a lot of company.

Quick answer: five is how many symptoms a clinician looks for, out of nine possible. Two people can both have major depression and share only one symptom.

The nine symptoms, in plain language#

These are the nine symptoms commonly associated with major depressive disorder. For a diagnosis they show up most of the day, nearly every day, and they are a change from how the person usually is (NIMH).

1. Depressed mood. Feeling sad, empty, or hopeless most of the day. In teens it can look more like irritability than sadness.
2. Loss of interest or pleasure. Clinicians call this anhedonia. A hobby, a favorite show, time with friends: the things you used to look forward to stop feeling like anything.
3. Appetite or weight changes. Eating much more or much less than usual, or a noticeable change in weight without trying.
4. Sleep changes. Trouble falling or staying asleep, waking very early, or sleeping far more than usual.
5. Moving or speaking differently. Being slowed down, or restless and keyed up, in a way other people can see.
6. Fatigue or loss of energy. Being worn out even after rest. A shower or a short email takes real effort.
7. Worthlessness or excessive guilt. Harsh self-blame, often over things that aren't yours to carry.
8. Trouble thinking, concentrating, or deciding. Rereading the same line, losing your train of thought, freezing over small choices.
9. Recurrent thoughts of death or suicide. This can range from "everyone would be better off without me" to a specific plan. Any version of it deserves attention right away.

The first two are the core pair. At least one of them has to be present for the diagnosis.

Why the same diagnosis can look so different

Because the threshold is five out of nine, depression has more than one face. Imagine someone who sleeps ten hours, eats more than usual, and feels heavy and slow. Now imagine someone who barely sleeps, has no appetite, and paces the kitchen at 3 a.m.

Both could meet the criteria. That is one reason a checklist falls short on its own, and why some people with high-functioning depression go unnoticed for years.

| What people expect | What it often looks like | |---|---| | Crying all day | Feeling numb or flat | | Staying in bed | Going to work, then collapsing at home | | Obvious sadness | A short temper, pulling away from people | | A clear reason | No clear reason at all |

What separates depression from a rough couple of weeks#

Sadness after a loss, a breakup, or a hard stretch at work is part of being human, and it usually moves. Major depression differs in how long it lasts, how many parts of life it touches, and how much it gets in the way.

• Duration. At least two weeks, nearly every day.
• Breadth. Mood plus body: sleep, appetite, energy, concentration.
• Impairment. Work, relationships, or basic routines start to slip.

Depression and exhaustion can also be hard to tell apart, and our guide on burnout vs. depression covers that overlap. A low mood that has lasted two years or more may point to something different again, called persistent depressive disorder.

Medical problems can produce similar symptoms. Thyroid conditions and some other health issues can look a lot like depression (Mayo Clinic). So a clinician looks at the whole picture and often suggests a checkup with a primary care provider too.

We dove deeper into this on our YouTube channel. Watch the full episode — about 19 minutes — for a walk through all nine symptoms and what a clinician looks for.

How a clinician makes the call#

A licensed clinician diagnoses major depressive disorder through a conversation. There is no blood test for it, and no quiz settles it. A first appointment usually covers what you have noticed, how long it has been going on, how it affects your days, your health history, and whether you have ever had periods of unusually high energy or mood.

Many clinicians also use a short questionnaire called the PHQ-9. It asks about the same nine symptoms over the past two weeks, and it has been studied for more than two decades as a measure of depression severity (Kroenke, Spitzer & Williams, Journal of General Internal Medicine, 2001).

A screening score is a starting point. It shows you and your clinician where to look. It does not replace the interview, and only a licensed professional can diagnose.

What helps: evidence-based treatment for depression#

Depression is treatable, and several kinds of talk therapy have solid research behind them. The American Psychological Association's clinical practice guideline recommends a number of psychotherapies for adults with depression, including the three below (APA).

Cognitive behavioral therapy (CBT) is a structured approach that looks at how thoughts, feelings, and actions feed each other, and builds skills for changing the patterns that keep depression going. Our guide to CBT explains how sessions work.

Behavioral activation helps you return, a little at a time, to activities that bring meaning or a sense of accomplishment. You start before the motivation comes back, because waiting for motivation is usually what keeps people stuck.

Interpersonal therapy (IPT) is time-limited and focuses on relationships, role changes, grief, and conflict, and how each connects to mood.

Some people are also helped by medication, alone or alongside therapy. Whether it belongs in your plan is a decision for a prescriber, such as a psychiatrist or your primary care provider, who knows your health history.

Many people find that symptoms ease with treatment, though the pace differs from person to person. For a fuller picture, see our overview of major depressive disorder symptoms, causes, and treatment.

What depression therapy looks like at CHC

At Coping & Healing Counseling, depression therapy happens by secure video, so you can meet with a licensed therapist from home anywhere in Georgia. Early sessions focus on understanding what you are dealing with and what you want to be different.

From there, you and your therapist agree on a plan and adjust it as you go. Our team has 15+ licensed therapists (LCSWs, LPCs, and LMFTs) who work with adults, couples, families, and teens 13 and older.

What you can do this week#

You don't need a diagnosis to take a small step. These are realistic for a week when energy is low.

• Write down what you notice. A few words each evening about sleep, mood, appetite, and energy. Two weeks of notes gives a clinician far more to work with than memory does.
• Take a screening. It can put words to what you are feeling and give you something concrete to bring to a first session.
• Tell one person. One sentence is enough: "I haven't felt like myself for a while."
• Shrink the day. Pick one small thing you can finish, like a ten-minute walk or a shower, and let that count.
• Check on someone you are worried about. Try: "I've noticed you seem worn down lately. How are you really doing?" Then listen.

Frequently Asked Questions#

Is there an official list of 5 symptoms of major depressive disorder?

No. The diagnostic criteria list nine symptoms, and a diagnosis generally requires at least five of them during the same two-week period. One of the five has to be depressed mood or a loss of interest or pleasure. Five is a threshold clinicians use. It is not a fixed set of symptoms.

How long do symptoms have to last to count as major depression?

The symptoms need to be present most of the day, nearly every day, for at least two weeks, and they need to be a change from how you usually function. They also have to cause real distress or interfere with work, relationships, or daily life. A licensed clinician makes that determination.

Can you have major depression without feeling sad?

Yes. The criteria require either depressed mood or a loss of interest or pleasure, so some people never describe themselves as sad. They may feel numb, flat, irritable, or disconnected. This is one reason depression gets missed in people who keep working and taking care of everyone else.

Can an online depression test diagnose me?

No. A screening test, including the widely used PHQ-9, can show whether your symptoms deserve a closer look and how severe they seem. It cannot rule out medical causes or other conditions. Only a licensed clinician can diagnose major depressive disorder, after talking with you about the full picture.

What is the difference between sadness and major depressive disorder?

Sadness is a normal emotion that usually has a cause and eases with time. Major depressive disorder involves at least five symptoms lasting two weeks or more. It affects sleep, energy, appetite, and concentration as well as mood, and it gets in the way of daily life.

What should I do if someone I love has thoughts of suicide?

Take it seriously and stay with them. Call or text 988 to reach the Suicide & Crisis Lifeline, or call the Georgia Crisis & Access Line at 1-800-715-4225. If there is immediate danger, call 911 or go to the nearest emergency room. Asking directly about suicide does not plant the idea.

When to seek professional help#

It is worth talking with a professional when symptoms have lasted two weeks or more, when work or relationships are slipping, or when you don't feel like yourself and can't shake it. You don't have to be sure it is depression first.

A simple place to start is our Free depression test. It takes a few minutes. It is a screening, not a diagnosis, and it gives you something concrete to bring to a first session.

When you are ready, Coping & Healing Counseling offers depression therapy through online therapy across Georgia, serving all 159 counties by HIPAA-compliant video. We accept Medicaid with a $0 copay, along with Aetna, Cigna, BCBS, UHC, and Humana. You can get started online or call (404) 832-0102.

If thoughts of suicide are part of what you are carrying, please don't wait. Call or text 988 now. Our guide on getting help for suicidal thoughts explains what to expect when you reach out.

Knowing the symptoms of major depressive disorder is a first step. The next one is letting someone qualified look at the whole picture with you.
