Following years of debate, researchers have found that t persistent depression causes brain damage and not the other way around.
Neurologists had previously thought that t brain damage was a predisposing factor for chronic depression, but according to a new study published in Molecular Psychiatry reveals something much different.
The study, which consisted of 9,000 individual samples, collected from the ENIGMA group, prospered in definitively proving a causal relationship in between persistent depression and mental retardation.
Magnetic resonance images (MRIs) showed evidence of hippocampus shrinking in 1,728 clients detected with persistent depression compared to the 7,199 healthy individuals partaking in the research study.
Specifically, the research study found that those clients detected with a significant depressive condition, “showed robust decreases in hippocampal volume (1.24%) in MDD clients compared to healthy controls.”

What is the hippocampus?
The hippocampus is a small location of the brain that is located in the medial temporal lobe of the brain. It is comprised of 2 halves, one of which resides on each hemisphere of the brain.
It generally concurs that the main performance of the hippocampus encompasses the development of new memories, the formation of long-term memory, and spatial navigation.
Inside the hippocampus resides the amygdala.
The amygdala is a part of the brain which has previously been linked with depression
Research studies in the past have recommended a direct relationship in between a shrinkage in the hippocampus and depression, but the sample size of previous research studies hasn’t been big enough to yield definitive outcomes.
The hippocampus and depression.
Scientists have discovered that in addition to its value in forming and keeping memories, the hippocampus is likewise essential in controlling emotions.
Teacher Ian Hickie, a co-author of the research study and a popular psychological health advocate, describes the hippocampus’ relationship to depression:
“Your whole sense of self-depends on continually understanding who you are in the world, your state of memory is not about just knowing the best ways to do Sudoku or remembering your password– it’s the whole principle we hold of ourselves”
Teacher Hickie further elaborates on the relationship in between a shrinkage in the hippocampus and modifications in habits observed in animals from the past:
“We’ve seen in a lot of other animal experiments that when you diminish the hippocampus, you do not just change memory, you alter all sorts of other behaviors related to that– so shrinking is connected with a loss of function.”
Those who struggle with depression usually have low self-confidence and lack self-confidence in managing their lives. It is common for those suffering from depression to likewise have a deflated ego, which merely describes a person’s sense of self.
This could potentially affect how one forms memories, and how they view themselves in the past and thus project themselves in the future.
What is depression?
Depression is a relatively helpless frame of mind where one takes very downhearted thought patterns as truth. The keyword is “apparently.”
Someone who is depressed typically has a deflated sense of self and a malfunctioning understanding of the world around them and how they see themselves in it.
I think that the state of depression manifests through repetitively regretting your past and fearing the future. It is not a particular conscious choice.
I believe that it is a consequence of recurring thought patterns that result in a negative outlook on life and one’s self in it.
An unfavorable outlook and believed cycle only lead to more unfavorable thoughts without some form of intervention.
Sort of how like an avalanche only goes faster and grows when careening down a snow-covered mountain.
These data worrying hippocampus decrease are intriguing as one might argue that the reduction in the hippocampus parallels this modification in idea pattern.
Could not it be harder for somebody with even the tiniest reduction to get out of this unfavorable thought cycle without the full capacity of their brain?
Change Your Outlook.
From my experience, my journey conquering this condition began when I accepted exactly what my misdirected thoughts were telling me for what they were thoughts.
I found for much of my life that I tried to escape this mindset which in a sense provided validity to it.
One simple, but efficient tool in breaking devoid of depression is to obtain in touch with the present moment. Meditation and yoga have actually been important in my daily life.
Surrounding yourself with positive individuals is likewise extremely helpful in getting rid of depression.
Often when someone is depressed, they simply can not see the light at the end of the tunnel or discover any hope in their life.
That does not suggest that those around them can’t show them it’s there though!
Depression in the United States.
Depression is not something that should be taken lightly.

Depression is not merely unhappiness, nor is it is the symptom of the weak point.
