Depression is a common condition that affects millions of people worldwide. There are different types of depression that range in severity. The two main categories are normal depression, which is mild and temporary, and major depressive disorder, which is more severe and persistent.
What is normal depression?
Normal depression, also called mild or temporary depression, involves feeling sad, empty, hopeless, or irritable for short periods of time. These depressive episodes often occur in response to stressful life events, such as the death of a loved one, divorce, job loss, or financial problems. Symptoms may include:
- Feeling sad, empty, or tearful
- Fatigue and lack of energy
- Changes in appetite
- Trouble sleeping
- Feelings of guilt, worthlessness, or helplessness
- Difficulty concentrating
The symptoms of normal depression are not severe enough to significantly interfere with day-to-day activities. Episodes typically last up to 2 weeks and resolve on their own or with support from loved ones. This type of depression does not usually require treatment with medication or therapy.
What is major depressive disorder?
Major depressive disorder (MDD), also known simply as depression, involves more intense and long-lasting symptoms compared to normal depression. To receive a diagnosis of MDD, symptoms must be present most of the day, nearly every day for at least 2 weeks. Symptoms of MDD may include:
- Persistent feelings of sadness, emptiness, hopelessness
- Irritability, restlessness, anger
- Loss of interest in activities once enjoyed
- Fatigue and lack of energy
- Changes in appetite
- Sleep disturbances
- Difficulty concentrating, remembering details, and making decisions
- Physical symptoms like headaches, stomach aches, back pain
- Feelings of worthlessness or excessive guilt
- Fixation on past failures, self-blame
- Thoughts of death, suicide attempts
The symptoms of MDD are severe enough to interfere significantly with the ability to function at work, school, or in social situations. People with MDD often struggle to take care of responsibilities and relationships. MDD must be formally diagnosed by a mental health professional.
What causes normal depression vs. major depressive disorder?
Normal depression is usually triggered by stressful life events, trauma, or significant changes. When the stressor passes or the person adapts, the depressive symptoms typically resolve. In contrast, MDD can occur without an obvious trigger. Researchers believe genetics, brain chemistry, hormones, and environmental factors play a role in the development of MDD.
Risk factors for MDD include:
- Family history of depression
- Trauma or abuse during childhood
- Certain medical conditions, like cancer, stroke, heart disease, Parkinson’s disease
- Substance abuse or addiction
- Use of certain medications, like steroids or blood pressure medications
- Sleep disturbances or insomnia
- Stressful life events, trauma, grief
People with MDD often have a combination of genetic, biological, environmental, and psychological factors that contribute to the condition. Identifying risk factors can help guide treatment and prevention efforts.
How are normal depression and MDD treated?
Normal depression often resolves on its own once the source of stress passes. Self-care strategies like getting enough sleep, eating a healthy diet, exercising, and practicing relaxation techniques can help alleviate symptoms. Support from family and friends can also shorten the duration of normal depressive episodes.
For MDD, a combination of medication and psychotherapy is generally the most effective treatment approach. The most common medications prescribed for depression are:
- Selective serotonin reuptake inhibitors (SSRIs)
- Serotonin and norepinephrine reuptake inhibitors (SNRIs)
- Atypical antidepressants
- Tricyclic antidepressants
- Monoamine oxidase inhibitors (MAOIs)
These medications help adjust brain chemicals like serotonin, norepinephrine, and dopamine to improve mood and relieve depressive symptoms. Psychotherapy provides coping techniques, teaches problem-solving skills, and modifies unhealthy thought and behavior patterns. Cognitive behavioral therapy (CBT) is a common type of talk therapy found effective for treating MDD.
How long do normal depression and MDD episodes last?
By definition, normal depression or a depressive episode typically resolves within about two weeks. Persistent depressed mood lasting most of the day, nearly every day for at least 2 weeks may indicate MDD. However, the duration of MDD can vary:
- Acute MDD lasts less than 2 years
- Persistent MDD continues for 2 or more years
- Some people have chronic MDD with relapses throughout their lifetime
On average, an untreated episode of MDD lasts 6-8 months. With treatment, the duration can be shortened significantly. Even with treatment, it’s common to experience residual symptoms or relapses. Ongoing treatment, lifestyle changes, and coping skills can help manage the condition.
How are normal depression and MDD diagnosed?
There are no medical tests to diagnose depression. A diagnosis is made based on the number and severity of symptoms present. To diagnose normal depression, a doctor looks for symptoms consistent with temporary depressive episodes related to stressors.
To diagnose MDD, doctors or mental health professionals conduct an evaluation involving:
- Questionnaires about symptoms, sleep and appetite changes, thoughts and behaviors
- Physical exam and lab tests to rule out medical conditions mimicking depression
- Psychiatric interview asking about family history, trauma, substance use
- Mental status assessment of speech, mood, thought process
- Review of symptoms and duration to identify depressive episodes
The criteria for MDD diagnosis include 5 or more consistent symptoms present nearly every day for at least 2 weeks. At least one symptom must be depressed mood or loss of interest/pleasure.

The table summarizes some of the main differences in symptoms between normal depression and major depressive disorder. While normal depression is often triggered by stressful events, MDD is more persistent and debilitating.
What are the health risks associated with MDD?
Untreated clinical depression or MDD can have serious health consequences. People with depression have an increased risk of developing:
- Heart disease
- Obesity and related illnesses
- Dementia and Alzheimer’s disease
- Substance abuse problems
- Chronic pain and other physical symptoms
- Reduced quality of life
Depression is also associated with increased mortality. People with MDD have a greater risk of suicide. Up to 60% of people who die by suicide have clinical depression or another mood disorder.
What are tips for coping with normal depression?
Here are some tips that can help manage symptoms of normal depression:
- Get regular exercise – aim for 30 minutes per day of activity you enjoy
- Follow a healthy, balanced diet with plenty of vegetables and lean proteins

With MDD, working closely with your mental health providers, identifying triggers, and actively managing your symptoms are important for day-to-day functioning and long-term wellbeing. Support from loved ones also makes a big difference in recovery.
What are the main takeaways about normal depression vs. major depressive disorder?
Here are some key points about the differences between normal depression and major depressive disorder:
- Normal depression is temporary and tends to resolve within about two weeks, while MDD is more chronic and persistent.
- MDD causes more severe, disabling symptoms that significantly interfere with daily functioning.
- Normal depression is usually triggered by stressful events or situations, whereas MDD can occur without an obvious cause.
