Many factors may play a role in depression, including genetics, brain biology and chemistry, and life events such as trauma, loss of a loved one, a difficult relationship, an early childhood experience, or any stressful situation.

Depression can happen at any age, but often begins in the teens or early 20s or 30s. Most chronic mood and anxiety disorders in adults begin as high levels of anxiety in children. In fact, high levels of anxiety as a child could mean a higher risk of depression as an adult.

Depression can co-occur with other serious medical illnesses such as diabetes, cancer, heart disease, and Parkinson’s disease. Depression can make these conditions worse and vice versa. Sometimes medications taken for these illnesses may cause side effects that contribute to depression. A doctor experienced in treating these complicated illnesses can help work out the best treatment strategy.

Research on depression is ongoing, and one day these discoveries may lead to better diagnosis and treatment. To learn more about current research, visit the NIMH website at www.nimh.nih.gov.

1) DEPRESSION QUIZ - PSYCH CENTRAL

There are several types of depressive disorders.

Major depression: Severe symptoms that interfere with the ability to work, sleep, study, eat, and enjoy life. An episode can occur only once in a person’s lifetime, but more often, a person has several episodes.

Persistent depressive disorder: A depressed mood that lasts for at least 2 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 2 years.

Some forms of depression are slightly different, or they may develop under unique circumstances. They include:

Psychotic depression, which occurs when a person has severe depression plus some form of psychosis, such as having disturbing false beliefs or a break with reality (delusions), or hearing or seeing upsetting things that others cannot hear or see (hallucinations).

Postpartum depression, which is much more serious than the “baby blues” that many women experience after giving birth, when hormonal and physical changes and the new responsibility of caring for a newborn can be overwhelming. It is estimated that 10 to 15 percent of women experience postpartum depression after giving birth.

Seasonal affective disorder (SAD), which is characterized by the onset of depression during the winter months, when there is less natural sunlight. The depression generally lifts during spring and summer. SAD may be effectively treated with light therapy, but nearly half of those with SAD do not get better with light therapy alone. Antidepressant medication and psychotherapy can reduce SAD symptoms, either alone or in combination with light therapy.

Bipolar disorder is different from depression. The reason it is included in this list is because someone with bipolar disorder experiences episodes of extreme low moods (depression). But a person with bipolar disorder also experiences extreme high moods (called “mania”).

Not everyone who is depressed experiences every symptom. Some people experience only a few symptoms. Some people have 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.

Women with depression do not all experience the same symptoms. However, women with depression typically have symptoms of sadness, worthlessness, and guilt.

Depression is more common among women than among men. Biological, lifecycle, hormonal, and psychosocial factors that are unique to women may be linked to their higher depression rate. For example, women are especially vulnerable to developing postpartum depression after giving birth, when hormonal and physical changes and the new responsibility of caring for a newborn can be overwhelming.

Men often experience depression differently than women. While women with depression are more likely to have feelings of sadness, worthlessness, and excessive guilt, men are more likely to be very tired, irritable, lose interest in once-pleasurable activities, and have difficulty sleeping.

Men may turn to alcohol or drugs when they are depressed. They also may become frustrated, discouraged, irritable, angry, and sometimes abusive. Some men may throw themselves into their work to avoid talking about their depression with family or friends, or behave recklessly. And although more women attempt suicide, many more men die by suicide in the United States.

Before puberty, girls and boys are equally likely to develop depression. A child with depression may pretend to be sick, refuse to go to school, cling to a parent, or worry that a parent may die. Because normal behaviors vary from one childhood stage to another, it can be difficult to tell whether a child is just going through a temporary “phase” or is suffering from depression. Sometimes the parents become worried about how the child’s behavior has changed, or a teacher mentions that “your child doesn’t seem to be himself.” In such a case, if a visit to the child’s pediatrician rules out physical symptoms, the doctor will probably suggest that the child be evaluated, preferably by a mental health professional who specializes in the treatment of children. Most chronic mood disorders, such as depression, begin as high levels of anxiety in children.

The teen years can be tough. Teens are forming an identity apart from their parents, grappling with gender issues and emerging sexuality, and making independent decisions for the first time in their lives. Occasional bad moods are to be expected, but depression is different.

Older children and teens with depression may sulk, get into trouble at school, be negative and irritable, and feel misunderstood. If you’re unsure if an adolescent in your life is depressed or just “being a teenager,” consider how long the symptoms have been present, how severe they are, and how different the teen is acting from his or her usual self. Teens with depression may also have other disorders such as anxiety, eating disorders, or substance abuse. They may also be at higher risk for suicide.

Children and teenagers usually rely on parents, teachers, or other caregivers to recognize their suffering and get them the treatment they need. Many teens don’t know where to go for mental health treatment or believe that treatment won’t help. Others don’t get help because they think depression symptoms may be just part of the typical stress of school or being a teen. Some teens worry what other people will think if they seek mental health care.

Depression often persists, recurs, and continues into adulthood, especially if left untreated. If you suspect a child or teenager in your life is suffering from depression, speak up right away.

Depression is treated with medicines, talk therapy (where a person talks with a trained professional about his or her thoughts and feelings; sometimes called “psychotherapy”), or a combination of the two. Remember: No two people are affected the same way by depression. 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.

Antidepressants are medicines that treat depression. They may help improve the way your brain uses certain chemicals that control mood or stress.

There are several types of antidepressants:

There are other antidepressants that don’t fall into any of these categories and are considered unique, such as Mirtazapine and Bupropion.

Although all antidepressants can cause side effects, some are more likely to cause certain side effects than others. You may need to try several different antidepressant medicines before finding the one that improves your symptoms and has side effects that you can manage.

Most antidepressants are generally safe, but the U.S. Food and Drug Administration (FDA) requires that all antidepressants carry black box warnings, the strictest warnings for prescriptions. In some cases, children, teenagers, and young adults under age 25 may experience an increase in suicidal thoughts or behavior when taking antidepressants, especially in the first few weeks after starting or when the dose is changed. The warning also says that patients of all ages taking antidepressants should be watched closely, especially during the first few weeks of treatment.

Common side effects listed by the FDA for antidepressants are:

Other more serious but much less common side effects listed by the FDA for antidepressant medicines can include seizures, heart problems, and an imbalance of salt in your blood, liver damage, suicidal thoughts, or serotonin syndrome (a life-threatening reaction where your body makes too much serotonin). Serotonin syndrome can cause shivering, diarrhea, fever, seizures, and stiff or rigid muscles.

Your doctor may have you see a talk therapist in addition to taking medicine. Ask your doctor about the benefits and risks of adding talk therapy to your treatment. Sometimes talk therapy alone may be the best treatment for you.
