Stress & Depression Early in Life Stunts Our Reward Circuits

Depression - child

Early life stress is a major risk factor for later episodes of depression. In fact, adults who are abused or neglected as children are almost twice as likely to experience depression.

Scientific research into this link has revealed that the increased risk following such childhood adversity is associated with sensitization of the brain circuits involved with processing threat and driving the stress response. More recently, research has begun to demonstrate that in parallel to this stress sensitization, there may also be diminished processing of reward in the brain and associated reductions in a person’s ability to experience positive emotions.

Researchers at Duke University and the University of Texas Health Sciences Center at San Antonio looked specifically at this second phenomenon in a longitudinal neuroimaging study of adolescents, in order to better understand how early life stress contributes to depression.

They recruited 106 adolescents, between the ages of 11-15, who underwent an initial magnetic resonance imaging scan, along with measurements of mood and neglect. The study participants then had a second brain scan two years later.

The researchers focused on the ventral striatum, a deep brain region that is important for processing rewarding experiences as well as generating positive emotions, both of which are deficient in depression.

“Our analyses revealed that over a two-year window during early to mid-adolescence, there was an abnormal decrease in the response of the ventral striatum to reward only in adolescents who had been exposed to emotional neglect, a relatively common form of childhood adversity where parents are persistently emotionally unresponsive and unavailable to their children,” explained first author Dr. Jamie Hanson.

    depression is a major issue in our world, and depression is exactly what it’s name is DE-pression the opposite of “expression”. People who are suffering with depression are suffering with issues from the past and or their present. All the traumatic/unsettling experiences and bad times they have been dealt have not been Dealt with in the right way. Most people tend to deprive themselves of expression which results in a build up of negative energy. this negative energy can cause a wide range of physical emotional and mental problems for people such as – depression, anxiety, back pain, anger, fear ect. humans need to understand the power of positive thinking. ,thoughts That we manifest become the feelings that we feel ,thoughts produce a chemical reaction in the brain, these tiny particles spinning are energy in motion (E-motion)
    Different types of thoughts all produce different levels of chemical reactions in the brain and there for we experience so many different feelings. The solution to happiness is simple, you must manifest your own happiness , for the way you live is how u will feel, practice of positive thinking and momentary awareness and making yourself familiar with ancient esoteric concepts and information is the way, but first u must remove urself from the past for it has already been, and do not wonder to far in the future for it has not come, this moment is precious and what you decide to make it !! To learn you also must unlearn!
