Major Depressive Disorder
Sadness is a natural part of the human experience. People may feel sad or depressed when a loved one passes away or when they’re going through a life challenge, such as a divorce or serious illness. These feelings are normally short-lived. When someone experiences persistent and intense feelings of sadness for extended periods of time, then they may have a mood disorder such as major depressive disorder (MDD).
MDD, also referred to as clinical depression, is a mental disorder and significant medical condition characterised by at least two weeks of pervasive low mood that can affect many areas of your life. Low self-esteem, loss of interest in normally enjoyable activities, low energy, and pain without a clear cause are common symptoms. It impacts mood and behavior as well as various physical functions, such as appetite and sleep. Some people have periods of depression separated by years, while others nearly always have symptoms present
The diagnosis of major depressive disorder is based on the person’s reported experiences and a mental status examinationmental also, health professional can make a diagnosis of major depressive disorder based on your symptoms, feelings, and behaviors.There is no laboratory test for the disorder, but testing may be done to rule out physical conditions that can cause similar symptoms and hospitalization may be necessary in cases with a risk of harm to self and may occasionally occur against a person’s wishes. Those with major depressive disorder are typically treated with counseling and antidepressant medication. Medication appears to be effective, but the effect may only be significant in the most severely depressed.
What can Cause Depression
- The biopsychosocial model proposes that biological, psychological, and social factors all play a role in causing depression. The diathesis–stress model specifies that depression results when a preexisting vulnerability, or diathesis, is activated by stressful life events. The preexisting vulnerability can be either genetic, implying an interaction between nature and nurture, or schematic, resulting from views of the world learned in childhood.
- Childhood abuse, either physical, sexual or psychological, are all risk factors for depression, among other psychiatric issues that co-occur such as anxiety and drug abuse. Childhood trauma also correlates with severity of depression, lack of response to treatment and length of illness. However, some are more susceptible to developing mental illness such as depression after trauma, and various genes have been suggested to control susceptibility and like other psychiatric conditions depression could also be genetic.
- Depression may also come secondary to a chronic or terminal medical condition, such as HIV/AIDS or asthma, and may be labeled “secondary depression. Depression may also be iatrogenic (the result of healthcare), such as drug-induced depression. Therapies associated with depression include interferons, beta-blockers, isotretinoin, contraceptives, cardiac agents, anticonvulsants, antimigraine drugs, antipsychotics, and hormonal agents such as gonadotropin-releasing hormone agonist. Drug abuse in early age is also associated with increased risk of developing depression later in life. Depression that occurs as a result of pregnancy is called postpartum depression, and is thought to be the result of hormonal changes associated with pregnancy.
