Major Depressive Disorder Treatment: Finding the Right Path to Recovery

What is Major Depressive Disorder?



Major depressive disorder, also known simply as depression, is a common but serious mood disorder that 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. Some key symptoms of major depressive disorder include:



- Persistent sad, anxious, or "empty" mood

- Feelings of hopelessness or pessimism

- Irritability, restlessness, or excessive crying

- Loss of interest or pleasure in activities once enjoyed

- Decreased energy, fatigue, being "slowed down"

- Problems with sleeping, sleeping too much, or finding it difficult to sleep

- Overeating or appetite loss

- Problems with concentrating, remembering, making decisions

- Persistent physical symptoms that do not respond to treatment, such as headaches, digestive disorders, and chronic pain

- Thoughts of death or suicide, or suicide attempts



Major Depressive Disorder Treatment must also cause significant distress or impairment in social, occupational, or other important areas of functioning. They cannot be due to the physiological effects of a substance or other medical condition.



What Causes Depression?



While the exact causes of depression are not fully known, it is believed to involve several factors:



Genetics - Depression tends to run in families. If a parent or sibling has depression, a person is more likely to develop it. This suggests that a genetic vulnerability can be passed down through generations.



Brain Chemistry - Abnormalities in certain neurotransmitters (chemical messengers that carry signals between brain cells) involved in mood regulation, such as serotonin and norepinephrine, may underlie some types of depression.



Life Events and Stressors - Stressful life events like loss of a loved one, financial problems, health issues, trauma, or social isolation can all trigger a depressed mood in vulnerable individuals or make existing depression worse. Persistent stressful life situations can lead to prolonged activation of the body's stress response and wear down a person's mental health.



Medical Conditions - Certain medical conditions like hyperthyroidism, cancer, heart disease, chronic fatigue syndrome, or chronic pain are associated with higher risks for depression.



Personality Traits - People with low self-esteem, poor social skills, and pessimistic styles of thinking may be more likely to experience depressive symptoms. Those with trauma histories or substance abuse issues also face increased risks.



Diagnosing Major Depressive Disorder



To be diagnosed with major depressive disorder, a person must have at least five of the core symptoms nearly every day for at least two weeks. These include depressed mood, lack of interest in activities, significant weight changes, insomnia or hypersomnia (excessive sleeping), psychomotor agitation or retardation, fatigue, worthlessness or inappropriate guilt, diminished ability to concentrate, and recurring thoughts about death or suicide.



The symptoms must also be significantly impairing the person's ability to function at work, school, or in relationships and social activities. A complete physical exam and lab tests will also rule out any medical conditions that could be causing similar symptoms.



A licensed mental health professional such as a psychologist or psychiatrist conducts a clinical interview and uses diagnostic criteria from the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) or the International Classification of Diseases (ICD-10) to determine if a major depressive disorder diagnosis is appropriate.



Understanding the Different Types of Depression



While major depressive disorder is the most common type, there are also some other forms of diagnosable depression:



Persistent Depressive Disorder - This formerly called dysthymia, it involves chronic depressed mood for at least two years along with other ongoing symptoms that interfere with functioning, but symptoms are less severe than major depression.



Premenstrual Dysphoric Disorder - Severe irritability, depressed mood, feeling overwhelmed or fatigued that occur weekly during the premenstrual phase of the menstrual cycle and stops within a few days of menstruation beginning.



Postpartum Depression - Affected about 15% of new mothers, onset within 4 weeks postpartum. Symptoms range from mild to severe and risk increases with things like family history depression, lack of social support, stressful life events.



Psychotic Depression - Presence of psychotic features along with depressive symptoms such as hallucinations and delusions of guilt, poverty, or illness.



Seasonal Affective Disorder (SAD) - Recurrent depression that occurs at the same time each year, usually starting in fall or winter months when there is less natural sunlight.



Bipolar Disorder - Involves cycling episodes of mania or hypomania in addition to major depressive episodes. Symptoms are more severe than regular ups and downs.



Treating Major Depressive Disorder



Once a diagnosis of major depressive disorder has been made, treatment should begin as soon as possible as untreated depression can worsen over time or even become treatment resistant. The goals of treatment are to relieve symptoms, improve functioning, and prevent future episodes and suicide risk.



The most common and effective treatments for treating major depression are:



Psychotherapy - Talk therapies such as cognitive behavioral therapy (CBT), interpersonal therapy, and others help change negative thought and behavior patterns that may contribute to depression. On average, 50-60% of people with major depression get substantial relief from psychotherapy alone.
