Heredity Plays A Part In Depression
28th December 2011 by Depressed No CommentsWhen individuals discuss someone being “depressed” quite often they are discussing what medical professionals term “unipolar depression”. Other terms used to describe the disorder are “clinical depression”, “major depressive illness”, and “major depression with melancholic features”. No matter the name, all these focus on the same illness found in the same region in the brain, destroying the identical cells and creating the exact same chemical imbalances. Other disorders that have “depression” in their title for example “bipolar depression” are quite distinctive in the cells and chemicals affected.
Over the last several decades scientific research has established a specific genetic link for unipolar depression. When one of your parents as well as other members of your immediate family are dealing with unipolar depression you have a one in five (20%) odss of battling it yourself. Should both parents receive the depressive gene your chances to be depressive too increase to one in two (50%). But even though no one in your family is experiencing unipolar depression, or has the genetic marker, the genes can and do show up spontaneously.
Just how essential this genetic aspect is has been shown by studies that focused on people with identical genes (twins) but, for a variety of reasons, were brought up apart by different parents. These medical studies concluded that, if both twins had the depression gene, both individuals were most probably affected by unipolar depression no matter the diverse lifestyle experiences and situations.
The genes which have been identified as causing unipolar depression act by allowing the brain to over react to stress activation. It’s normal for everybody to secrete a steroid stress hormone to the body and certain chemicals into the brain when confronted with a stressful situation. Even though this process is utterly normal, those who suffer from unipolar depression aren’t able turn off these hormones and chemicals once the stress is past. And when these substances remain at excessive levels for too prolonged a time, they cause significant damage to healthy brain cells which is a main contributing cause to the disease.
As an example, athletes who perform at high levels frequently release steroid stress hormones to fulfill a physical challenge such as catching a pass or hitting a baseball in a pressure circumstance. This happens for a very a brief period of time, when the immediate challenge is past the athlete’s body turns off the stress response and the entire body reverts to its standard state.
In those individuals who carry the genes associated with unipolar depression these responses to tension aren’t able to be turned off. All of the normal stresses of day-to-day life cause large amounts of the steroid stress hormones as well as other chemicals to flood the brain and this excess may cause significant injury to normally healthy brain cells which eventually causes unipolar depression.
The way our bodies and brains respond to the challenges and stresses of society are very complex.
