Depression Education
Depression is a common mental health condition that can affect how you feel, think, sleep, eat, and handle daily life. It is more than feeling sad or having a difficult day. Depression can cause ongoing low mood, loss of interest or pleasure, low energy, trouble concentrating, sleep changes, and other symptoms that interfere with everyday activities.
Depression, also called major depressive disorder, is a mental health condition that affects mood, thoughts, behavior, and daily functioning.
A person with depression may feel sad, empty, hopeless, irritable, or disconnected from things they usually enjoy. Symptoms can also affect sleep, appetite, energy, concentration, motivation, and physical well-being.
Depression can range from mild to severe. It is treatable, but the right treatment plan depends on the person’s symptoms, health history, and individual needs.
Sadness is a normal emotion that often develops in response to disappointment, loss, stress, or another difficult experience. It may improve as circumstances change or with time and support.
Depression usually involves a wider group of symptoms that last longer and interfere with everyday life. A clinician may consider how long symptoms have been present, how severe they are, and how much they affect work, school, relationships, sleep, self-care, or other daily activities.
Depression does not look exactly the same for everyone. Some people experience emotional symptoms, while others notice changes in sleep, energy, concentration, appetite, or physical functioning.
Some people with depression may have repeated thoughts about death, suicide, or self-harm. These symptoms require prompt attention and should not be ignored.
Depression usually does not have one single cause. A combination of biological, genetic, psychological, medical, environmental, and life factors may contribute.
Depression can affect anyone. Risk may be higher in people with a personal or family history of depression, significant stress or trauma, chronic health problems, major life changes, or other mental health conditions.
Having one or more risk factors does not mean someone will develop depression.
Depression can occur in several forms. The type, pattern, duration, and severity of symptoms can help guide diagnosis and treatment.
Major depressive disorder involves episodes of depression that may include low mood, loss of interest, changes in sleep or appetite, low energy, poor concentration, and other symptoms that affect daily life.
Persistent depressive disorder involves long-lasting depressive symptoms that may continue for years. Symptoms may be less severe at times but can still affect daily functioning.
Some people experience depression during a particular season of the year, often during months with less daylight.
Depression can occur during pregnancy or after childbirth and may affect mood, sleep, bonding, energy, and daily functioning.
Bipolar disorder can include periods of depression, but it is different from major depressive disorder because people with bipolar disorder also experience manic or hypomanic episodes.
Because treatment may differ, identifying the correct diagnosis is important. Learn more about bipolar disorder.
Depression is diagnosed based on your symptoms, how long they have been present, how they affect daily life, and your overall medical and mental health history.
During an evaluation, a healthcare professional may ask about your mood, sleep, appetite, energy, concentration, motivation, medications, substance use, medical conditions, stress, and other symptoms.
A clinician may also use a structured depression questionnaire to help measure symptoms and track changes over time.
In some cases, medical evaluation or laboratory testing may be considered to look for health conditions that could contribute to symptoms.
Diagnosis is not based on a single symptom or an online checklist. A professional evaluation can help determine whether symptoms are consistent with depression or another condition.
Depression treatment is individualized. Depending on the type and severity of symptoms, treatment may include psychotherapy, medication, supportive lifestyle changes, or a combination of approaches.
Psychotherapy, often called talk therapy, can help people identify patterns in thoughts, emotions, behaviors, relationships, and coping. Different types of therapy may be used depending on the person’s needs.
Antidepressant medications may be considered for some people with depression. Medication choice depends on symptoms, health history, previous treatment, possible side effects, and other factors.
Sleep, regular movement, social connection, daily routines, nutrition, stress management, and treatment of other health conditions may support recovery as part of an overall care plan.

Coping strategies can support recovery, especially when used alongside professional care when needed.
Depression can make even basic tasks feel difficult. Small, realistic steps may be more manageable than trying to make many changes at once.
Some people continue to have depression symptoms even after starting treatment. This does not automatically mean there are no other options.
A clinician may need to review the diagnosis, treatment history, medication response, side effects, other health conditions, sleep, stress, and additional factors before deciding what may be appropriate next.

Consider talking with a mental health or healthcare professional if symptoms are persistent, worsening, or interfering with your work, school, relationships, parenting, sleep, appetite, self-care, motivation, or other daily responsibilities.
You do not have to wait until symptoms become severe before asking for help. An evaluation can help clarify what you are experiencing and whether treatment may be appropriate.
