Depression: A Common but Serious Mood Disorder

Depression is a mood disorder that causes a persistent feeling of sadness and loss of interest. It can affect how you feel, think and behave and can interfere with your daily functioning. Depression is not a sign of weakness or a character flaw. It is a treatable medical condition that affects millions of people around the world.
What are the symptoms of depression?
Depression can cause a variety of symptoms, some of which may include:
- Persistent sad, anxious or empty mood
- Feelings of hopelessness, pessimism, guilt, worthlessness or helplessness
- Loss of interest or pleasure in hobbies and activities
- Decreased energy, fatigue or feeling slowed down

The severity, frequency and duration of these symptoms may vary depending on the individual and the type of depression. To be diagnosed with depression, the symptoms must be present for at least two weeks.
What are the causes of depression?

There is no single cause of depression. It is likely the result of a complex interaction of biological, psychological, social and environmental factors. Some of the possible risk factors for developing depression include:
- Having a family history of depression or other mental disorders
- Experiencing stressful life events such as loss, trauma, abuse, divorce or financial problems
- Having a chronic medical condition such as diabetes, heart disease, cancer or chronic pain
- Having certain personality traits such as low self-esteem, pessimism or perfectionism
- Using alcohol or drugs to cope with stress or negative emotions
- Hormonal changes during pregnancy, postpartum period, menopause or premenstrual syndrome
- Lack of social support or isolation
- Exposure to violence, neglect or poverty
However, it is important to note that depression can affect anyone at any age and from any background. It is not a sign of personal weakness or a character flaw. It is a treatable medical condition that requires professional help.
How is depression treated?

The good news is that depression is treatable and most people can recover from it with appropriate care. The most common forms of treatment for depression are medication and psychotherapy. Sometimes, a combination of both may be recommended.
Medication: Antidepressants are drugs that work by affecting the levels of certain chemicals in the brain called neurotransmitters. They can help improve mood, sleep, appetite and concentration. There are different types of antidepressants available and they may have different effects and side effects depending on the individual. It may take several weeks for antidepressants to start working and it is important to follow the doctor’s instructions and not stop taking them without consulting the doctor first.
Psychotherapy: Psychotherapy (also called talk therapy or counseling) is a process where a trained mental health professional helps the person with depression understand and cope with their thoughts, feelings and behaviors. Psychotherapy can help the person identify and change negative patterns of thinking and behavior that contribute to depression. It can also help the person develop coping skills, improve self-esteem and enhance relationships. There are different types of psychotherapy such as cognitive-behavioral therapy (CBT), interpersonal therapy (IPT), psychodynamic therapy and family therapy.
In addition to medication and psychotherapy, there are other ways to help manage depression such as:
- Lifestyle changes: Eating a balanced diet, exercising regularly, getting enough sleep and avoiding alcohol and drugs can help improve physical and mental health.
- Social support: Reaching out to family, friends, support groups or online communities can provide emotional support and reduce isolation.
- Self-care: Engaging in activities that bring joy and relaxation such as hobbies, music, art, meditation or yoga can help reduce stress and
