What is Depression?
Depression (major depressive disorder or clinical depression) is a common but serious mood disorder. It causes severe symptoms that affect how you feel, think, and handle daily activities, such as sleeping, eating, or working. To be diagnosed with depression, the symptoms must be present for at least two weeks.
Despite significant distress to the individual impairment in functioning and loss of lives to suicide, depression continues to be under-recognized and under-treated.

Types Of Depression ( What is Depression? )
- Persistent depressive disorder (also called dysthymia) is a depressed mood that lasts for at least two years. A person diagnosed with persistent depressive disorder may have episodes of major depression along with periods of less severe symptoms, but symptoms must last for two years to be considered persistent depressive disorder.
- Postpartum depression is much more serious than the “baby blues” (relatively mild depressive and anxiety symptoms that typically clear within two weeks after delivery) that many women experience after giving birth. Women with postpartum depression experience full-blown major depression during pregnancy or after delivery (postpartum depression). The feelings of extreme sadness, anxiety, and exhaustion that accompany postpartum depression may make it difficult for these new mothers to complete daily care activities for themselves and/or for their babies.
- Psychotic depression occurs when a person has severe depression plus some form of psychosis, such as having disturbing false fixed beliefs (delusions) or hearing or seeing upsetting things that others cannot hear or see (hallucinations). The psychotic symptoms typically have a depressive “theme,” such as delusions of guilt, poverty, or illness.
- Seasonal affective disorder is characterized by the onset of depression during the winter months, when there is less natural sunlight. This depression generally lifts during spring and summer. Winter depression, typically accompanied by social withdrawal, increased sleep, and weight gain, predictably returns every year in seasonal affective disorder.
- Bipolar disorder is different from depression, but it is included in this list because someone with bipolar disorder experiences episodes of extremely low moods that meet the criteria for major depression (called “bipolar depression”). But a person with bipolar disorder also experiences extreme high – euphoric or irritable – moods called “mania” or a less severe form called “hypomania.”
Examples of other types of depressive disorders newly added to the diagnostic classification of DSM-5 include disruptive mood dysregulation disorder (diagnosed in children and adolescents) and premenstrual dysphoric disorder (PMDD).
Signs and Symptoms of Depression
If you have been experiencing some of the following signs and symptoms most of the day, nearly every day, for at least two weeks, you may be suffering from depression:
- Persistent sad, anxious, or “empty” mood
- Feelings of hopelessness, or pessimism
- Feelings of guilt, worthlessness, or helplessness
- Loss of interest or pleasure in hobbies and activities
- Decreased energy or fatigue
- Moving or talking more slowly
- Feeling restless or having trouble sitting still
- Difficulty concentrating, remembering, or making decisions
- Difficulty sleeping, early-morning awakening, or oversleeping
- Appetite and/or weight changes
- Thoughts of death or suicide, or suicide attempts
- Aches or pains, headaches, cramps, or digestive problems without a clear physical cause and/or that do not ease even with treatment
Not everyone who is depressed experiences every symptom. Some people experience only a few symptoms while others may experience many. The severity and frequency of symptoms and how long they last will vary depending on the individual and his or her particular illness. Symptoms may also vary depending on the stage of the illness.
Risk Factors for Depression
Depression is one of the most common mental disorders in the world. Current research suggests that depression is caused by a combination of genetic, biological, environmental, and psychological factors.
- Personal or family history of depression
- Major life changes, trauma, or stress
- Certain physical illnesses like diabetes, cancer, etc
- Certain medications like anti tuberculosis medicines, steroids, contraceptives etc
- Certain Psychoactive substances/ drug abuse/ drug addictions like alcohol, cannabis etc
- Severe neurological illnesses like epilepsy, Parkinson’s, Dementia etc
- Post head injury, post stroke etc.
Depression, even the most severe cases, can be treated. The earlier that treatment can begin, the more effective it is. Depression is usually treated with medications, psychotherapy, or a combination of the two. If these treatments do not reduce symptoms, electroconvulsive therapy (ECT) and other brain stimulation therapies may be options to explore.
Quick Tip: No two people are affected the same way by depression and there is no “one-size-fits-all” for treatment. It may take some trial and error to find the treatment that works best for you.
ANTIDEPRESSANT MEDICATIONS OR MEDICINES FOR DEPRESSION
Antidepressants are medicines that treat depression. They may help improve the way your brain uses certain chemicals that control mood or stress. Rarely, one may need to try different antidepressant medicines before finding the one that improves your symptoms and has manageable side effects. A medication that has helped you or a close family member in the past will often be considered.
Antidepressants take time – usually 2 to 4 weeks – to work, and often, symptoms such as sleep, appetite, and concentration problems improve before mood lifts, so it is important to give medication a chance before reaching a conclusion about its effectiveness.
If you begin taking antidepressants, do not stop taking them without the help of a doctor. Sometimes people take antidepressants to feel better and then stop taking the medication on their own, and the depression returns. When you and your doctor have decided it is time to stop the medication, usually after a course of 6 to 12 months, the doctor will help you slowly and safely decrease your dose. Stopping them abruptly can cause withdrawal symptoms.
If you are considering taking an antidepressant and you are pregnant, planning to become pregnant, or breastfeeding, talk to your doctor about any increased health risks to you or your unborn or nursing child.
COUNSELING FOR DEPRESSION/ PSYCHOTHERAPY FOR DEPRESSION
Several types of psychotherapy (also called “talk therapy” or, in a less specific form, counseling) can help people with depression. There are different types of therapy available that are chosen as per the patient’s symptoms. Examples of evidence-based approaches specific to the treatment of depression include
Cognitive-behavioral therapy (CBT)
Interpersonal therapy (IPT)
BRAIN STIMULATION THERAPIES
If medications do not reduce the symptoms of depression, electroconvulsive therapy (ECT) may be an option to explore. Based on the latest research:
- ECT can provide relief for people with severe depression who have not been able to feel better with other treatments.
- In some severe cases where a rapid response is necessary or medications cannot be used safely, ECT can even be a first-line intervention.
- Once strictly an inpatient procedure, today ECT is often performed on an outpatient basis. The treatment consists of a series of sessions, typically three times a week, for two to four weeks.
- ECT may cause some side effects, including confusion, disorientation, and memory loss. Usually these side effects are short-term, but sometimes memory problems can linger, especially for the months around the time of the treatment course. Advances in ECT devices and methods have made modern ECT safe and effective for the vast majority of patients.
- ECT is not painful, and you cannot feel the electrical impulses. Before ECT begins, a patient is put under brief anesthesia and given a muscle relaxant. Within one hour after the treatment session, which takes only a few minutes, the patient is awake and alert.
Other more recently introduced types of brain stimulation therapies used to treat medicine-resistant depression include
Repetitive transcranial magnetic stimulation (rTMS) and
Vagus nerve stimulation (VNS).
If you think you may have depression, start by making an appointment to see your doctor or health care provider.
