Depression

Sadness touches our lives at different times but usually comes and goes. Depression, in contrast, often has enormous depth and staying power. It is more than a passing bout of "the blues." a “bad day,” or temporary sadness. Depression can leave you feeling continuously burdened and can drain the joy you once got out of pleasurable activities.

The most common symptom of depression is a low mood that can sometimes appear as irritability. For someone who is depressed, things that used to feel rewarding or meaningful no longer hold the same appeal.

The good news is that depression is treatable, and understanding its types and recognizing its symptoms is an important first step toward finding effective help and feeling better.

Types of depression?

Depression isn't a one-size-fits-all illness. Instead, it can take many forms and everyone's experience is different.

There are several types of depression, including:

Major depression. With major depression, there is a profound sadness or a sense of despair. The symptoms of major depression are defined as lasting at least two weeks, but usually they go on much longer.You may hearmajor depression called clinical depression or major depressive disorder (MDD), which are the medical terms that doctors use when major depression is clinically diagnosed.

Bipolar disorder (previously called manic depression or manic depressive illness). Bipolar disorder is a mental disorder characterized by wide mood swings from high (manic) to low (depressed). It is commonly divided into two subtypes (bipolar I and bipolar II) based on the dividing line between mania and hypomania.

  • Bipolar I disorder is the classic form where a person has had at least one manic episode.
  • In bipolar II disorder, the person has never had a manic episode but has had at least one hypomanic episode and at least one period of significant depression.

Most people who have manic episodes also experience periods of depression. In fact, there is some evidence that the depression phase is much more common than periods of mania in this illness. Bipolar depression can be much more distressing than mania and, because of the risk of suicide, is potentially more dangerous.

Persistent depressive disorder (previously called dysthymia). Persistent depressive disorder is less severe than an episode of major depression, but lasts longer. Many people with this disorder describe having been depressed as long as they can remember or feeling as though they go in and out of depression all the time.

Peripartum depression (or postpartum depression). Peripartum refers to the period during pregnancy and after childbirth. If a woman has significant symptoms of depression within weeks to months after giving birth, she may havepostpartum depression. Peripartum depression is not the same as the "baby blues," a term that describes the very common and brief period of emotional sensitivity that usually doesn't interfere with functioning as a mother, and almost always goes away within a few weeks. Peripartum depression affects up to 15% of new mothers.

Seasonal affective disorder. Depression that occurs mainly during the winter months is usually called seasonal affective disorder, or SAD. It also may be called major depressive disorder with seasonal pattern.

What are the main symptoms of depression?

A variety of symptoms usually accompany the low mood of any type of depression. And the symptoms can vary significantly among different people.

A depressed person may gain or lose weight, eat more or less than usual, have difficulty concentrating, and have trouble sleeping or sleep more than usual. He or she may feel tired and have no energy for work or play. Small burdens or obstacles may appear impossible to manage. The person can appear slowed down, or agitated and restless. The symptoms can be quite noticeable to others.

A particularly painful symptom of this illness is an unshakable feeling of worthlessness and guilt. The person may feel guilty about a specific life experience or may feel general guilt not related to anything in particular. If pain and self-criticism become great enough, they can lead to feelings of hopelessness, self-destructive behavior, or thoughts of death and suicide. The vast majority of people who suffer severe depression do not attempt or die by suicide, but they are more likely to do so than people who are not depressed.

Many people with depression also have anxiety. They may worry more than average about their physical health. They may have excessive conflict in their relationships, or function poorly at work. Sexual functioning may also be a problem.

Symptoms of major depression include:

  • distinctly depressed or irritable mood
  • loss of interest or pleasure
  • decreased or increased weight or appetite
  • decreased or increased sleep
  • appearing slowed or agitated
  • fatigue and loss of energy
  • feeling worthless or guilty
  • poor concentration or indecisiveness
  • thoughts of death, or suicide plans or attempts.

Lesser known symptoms of depression include substance use, pain, and neglecting personal hygiene.

People with persistent depressive disorder may have many of the same symptoms. While the symptoms tend to be less severe, they are long-lasting.

Specific to postpartum depression, in addition to usual depressive symptoms, a new mother with it may find it hard to concentrate and lose interest in anything, even the baby. Some mothers may feel overwhelmed by the baby's needs and become intensely anxious. This can lead to persistent troubling thoughts or obsessions about the baby's well-being and compulsive repetitive actions, such as checking on the baby constantly or phoning the pediatrician repeatedly to ask questions.

How is depression diagnosed?

It's important to be evaluated by a doctor or other health care professional, since physical illnesses and medication side effects can sometimes cause or worsen depression. The simplest screening tool to help determine if a person may be depressed is called the Patient Health Questionnaire‑2 (PHQ-2) which covers two core questions about depression:

Over the last two weeks, how often have you experienced:

  • little interest or pleasure in doing things
  • feeling down, depressed, or hopeless.

If the answers reflect more than several days over the past two weeks, your doctor will pursue additional questions.

Many people with depression do not seek evaluation or treatment because of stigma. The person may feel the depression is their fault or may worry about what others will think. Also, the depression itself may distort a person’s ability to recognize the problem. People with depression are also at more risk of abusing alcohol or other substances. For all of these reasons, it is especially important for family members or friends to encourage someone showing symptoms of depression to seek help.

How is depression treated?

No single treatment, whether it’s a drug or a style of therapy, can ease depression in every case. However, research suggests you will improve your chances of getting relief if you combine antidepression medication and therapy. One report that pooled findings from 25 studies found that adding psychotherapy to an antidepressant drug was more helpful than medication alone in treating major depression. Earlier research suggested that one reason therapy and medication may complement each other is that they have different effects on the brain.

Often, treatment is divided into three phases. Keep in mind, though, that there are no sharp lines dividing the phases, and very few people take a straight path through them.

  1. In the initial phase, the aim is to relieve symptoms. Generally, this occurs within four to eight weeks, but it may take longer depending on your response to the first treatments you try.
  2. In the continuation phase, you work with your doctor to maximize your improvements. Further treatment adjustments, such as modifying the dosage of a depression medication and sometimes adding a second drug, can help. This period may take another four to five months.
  3. In the maintenance phase, the aim is to prevent relapse. Ongoing treatment is often necessary, especially if you have already experienced several depressive episodes, have chronic low mood, or have risk factors that make a recurrence more likely.

It is often reasonable to start with either an antidepressant medication or psychotherapy. For mild depression, therapy is oftentimes preferred over medication. For moderate depression, either therapy or medication are reasonable. Generally, as symptoms become more severe, it is more important to consider medication earlier in your treatment. If one type of treatment alone isn’t helping you — and especially if your depression is getting worse — you can always try combination treatment.

Of course, consider all your options carefully, and discuss them with the professional you are consulting.

Medication for depression

A medication from a class of antidepressants called selective serotonin reuptake inhibitors (SSRIs) is often prescribed first. These medications include fluoxetine (Prozac), sertraline (Zoloft), paroxetine (Paxil), citalopram (Celexa), and escitalopram (Lexapro). They are not without problems, but they are fairly easy to take and relatively safe compared with previous generations of antidepressants.

SSRIs are known to cause problems with sexual functioning, some nausea, and an increase in anxiety in the early stages of treatment.

Other effective antidepressants include bupropion (Wellbutrin), venlafaxine (Effexor), mirtazapine (Remeron), and duloxetine (Cymbalta).

In recent years, newer medications have become available including vortioxetine (Trintellix) and vilazodone (Viibryd), which work somewhat differently from SSRIs. Dextromethorphan/bupropion (Auvelity) may work faster than traditional antidepressants. For treatment-resistant depression, esketamine (Spravato), a nasal spray given under medical supervision, is an option. For peripartum depression, zuranolone (Zurzuvae) is a short-term oral medication.

It usually takes at least two to six weeks of taking an antidepressant to see improvement. It may take several attempts to find the medication that works best. Once the right medication is found, it may take up to a few months to find a proper dose and for the full positive effect to be seen.

Therapy for depression

A number of different psychotherapy techniques have been demonstrated to be helpful, depending on the causes of the depression, the availability of family and other social support, and an individual's personal style and preference. A technique called cognitive behavioral therapy can help a depressed person recognize negative thinking and teach techniques for controlling symptoms. Other types of therapy, including psychodynamic, insight-oriented, and interpersonal psychotherapy, can help depressed people to sort out conflicts in important relationships or explore the history behind symptoms.

Lifestyle approaches for depression

In addition to medication and talk therapy, other modalities such as exercise can help alleviate some symptoms of depression. Research shows that exercise is one of the most effective lifestyle treatments for depression. Evidence also suggests that yoga, with its combination of breathwork, mindfulness, and physical activity, can offer specific benefits.

Interventions such as light therapy in the winter can help some people with seasonal affective disorder. This form of therapy is also recommended for nonseasonal depression as well.

Some research suggests an association between a Mediterranean diet and a lessening of depressive symptoms.

If you suffer from depression, you will benefit from learning all you can about the illness. You can also make use of any support networks that may be available in your community.

Does taking an antidepressant increase suicide risk?

The FDA still requires manufacturers of antidepressants to include a so-called “black box warning” on their product labeling. The warning is intended to address the concern that antidepressants may increase the risk of suicide in children, adolescents, and young adults. This problem has remained a focus of research, but the evidence surrounding it remains hard to interpret.

A small number of young people taking these medications probably do have an unusual reaction and end up feeling much worse, rather than better. Any medication that affects mood can have an unexpected negative effect in some people.

However, some experts worry that this warning has had too much of a chilling effect on the use of antidepressants for treatment. It is potentially dangerous for both doctors and patients to be too cautious about using a helpful intervention. When depression goes untreated, the risk of suicide goes up. Paradoxically, it is possible that the labeling puts more people at risk for suicide if it means that some people do not receive the treatment they need.

Therefore, independent of this debate, it is always important to monitor your treatment closely. No matter what age you are or what treatment you’re getting, report any troubling symptoms or worsening mood to your doctor immediately.

What causes depression?

Depression arises from a combination of biological, psychological, and environmental factors. Certain brain regions that regulate mood may not function as well in people with depression, and communication between nerve cells in these areas can become disrupted, making it harder for a person's brain to regulate his or her mood.

Hormone changes, such as during pregnancy or the postpartum period, and thyroid disorders may also negatively affect mood. An individual’s life experiences can further affect these biological processes while a person's genetic makeup can also influence how vulnerable they are to experiencing depression.

An episode of depression can be triggered by a stressful life event. But in many cases, depression does not appear to be related to a specific event.

Episodes of depression can occur at any age. Depression is diagnosed in women twice as often as in men, which may partly reflect differences in how women and men report symptoms and seek care. People who have a family member with major depression are more likely to develop depression or drinking problems.

How to help someone with depression

Like a pebble thrown into a pond, depression creates ripples that spread far from their immediate point of impact. Those closest to people who have these illnesses often suffer alongside them. It’s upsetting and often frustrating to deal with the inevitable fallout. But you can do a lot to help a loved one and yourself handle this difficult period.

Encourage them to get treatment and stick with it. Remind the person about taking antidepressant medication or keeping therapy appointments.

Don’t ignore comments about suicide. If you believe your loved one is suicidal, call his or her doctor or therapist. Mental health professionals can’t divulge information about a patient without permission, but it is not a violation of confidentiality for them to listen to you. In urgent situations, if you can’t reach the doctor or therapist, you may want to call a local crisis hotline for advice or bring the person to a local ER.

Care for yourself. Being a caregiver is a difficult job. You may want to seek individual therapy or join a support group. Numerous mental health organizations sponsor such groups, and can also provide you with information on the illness and the latest treatments.

Offer emotional support. Your patience and love can make a huge difference. Ask questions and listen carefully to the answers. Try not to brush off or judge the other person’s feelings, but do offer hope. Suggest activities that you can do together, and keep in mind that it takes time to get better. Don’t worry if you don’t know what to say; it takes a great deal of training (such as that received by therapists) to advise people in emotional distress.

Recognize that depression may manifest as irritability or anger, which is often directed toward family and other loved ones. Remind yourself that a disease is causing your loved one to act differently or perhaps be difficult. Do not blame him or her, just like you wouldn’t if it were chronic physical pain that caused the person to change in certain ways.
