Etiology of depression

What are the causes of depression? What is the pathophysiology of depression? How does the brain affect depression? BIOLOGICAL PERSPECTIVES ON THE ETIOLOGY OF DEPRESSION. A complex set of biological processes has been implicated in the etiology and course of depression—although such research has not always clarified whether such processes are underlying causal factors, correlates, or consequences of depression.

Depression in someone who has the biological vulnerability to develop depression may result from personal conflicts or disputes with family members or friends.

Depression is a mood disorder that causes a persistent feeling of sadness and loss of interest. Also called major depressive disorder or clinical depression , it affects how you feel, think and behave and can lead to a variety of emotional and physical problems. However, what they are unaware of is, that one of the major withdrawal symptoms of such substances is depression.

As such, substance abuse further contributes to depression. Nutrient Deficiency : In several cases, the deficiency of nutrients such as folic acid and Vitamin Bleads to the development of depression. The etiology of depression in children cannot be explained by one mechanism, as it is likely a combination of biology, personality traits, and life events. The essential amino acids are precursors to the neurotransmitters associated with depressions : serotonin , norepinephrine, phenylethylamine , and histamine.

A loss of interest in activities or feeling sad and down are symptoms that characterize this condition.

Even though most people feel sad or down for brief periods, calinical depression is more than just feeling sad. Clinically, earlier age of onset is associ- ated with a worse course of depression with greater chances of recurrence, chronicity, and impairment. Onset of depression more complex than a brain chemical imbalance.

One potential biological cause of depression is an imbalance in the neurotransmitters which are involved in mood regulation. Certain neurotransmitters, including dopamine, serotonin, and norepinephrine, play an important role in mood. Neurotransmitters are chemical substances that help different areas of the brain communicate with each other.

Depression (major depressive disorder or clinical depression ) is a common but serious mood disorder. It 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 symptoms of depression include: Persistent sa anxious, or “empty” mood. Feelings of hopelessness or pessimism. Loss of interest or pleasure in hobbies or activities. Decreased energy, fatigue, or being “slowed down”.

In spite of depression being a mental illness that will affect more than of the population at some point in their lives, the main causes of depression are yet to be pinpointed. Physical and psychological factors appear to cause depression in adults, teens and children. Depression has been linked to problems or imbalances in the brain, specifically with the neurotransmitters serotonin, norepinephrine, and dopamine. Depression may result from personal conflicts or disputes with family members or friends.

Sadness or grief from the death or loss of a loved one, though natural, can also increase the risk of depression. A family history of depression may increase the risk. Major depressive disorder has significant potential morbidity and mortality, contributing to suicide, incidence and adverse outcomes of medical illness, disruption in interpersonal relationships, substance abuse, and lost work time.
